Title: Wire lead nipping tool
IPC: H02G1/00
Filed: 1962-09-17
Abstract: 957,552. Nipping. CHICAGO PNEUMATIC TOOL CO. Sept. 17, 1962 [Oct. 26, 1961], No. 38301/62. Heading B3W. A pneumatically operated wire nipping tool adapted to be held in the palm of the hand and having a pneumatic throttle control arrangement which includes a manipulative lever 71 that may be adjusted for operation of the throttle valve, comprises a cylindrical body 11 closed at one end, a detachable cylinder head 14 rotatively adjustable in the opposite end of the body, a pair of crossed levers 17, 18 carried by the cylinder head, each having a cutting jaw at one end, a pneumatically powered piston 39 for actuating the levers relatively to one another and means for releasably locking the cylinder head in its adjusted position. The cylinder head 14 has a screw threaded connection 31 with the cylinder 11, the cylinder head having a cylindrical interior area 36 which combines with the cylindrical bore 13 in the cylinder 11 to form a piston chamber. The forward end of the piston has a central slot the bottom surface of which forms a cam slide 49. The cylinder head has a rectangular interior area 41 forwardly of the cylindrical interior area 36, the rear ends of the levers 17, 18 extending slidably through the rectangular area 41. The nipper implement is pivoted on a cross pin 15 which passes through the lever 18. A spring 27 biases the levers apart so that the cammed under surface of the lever 17 is adapted to ride up and down the cam slide 49. A pair of coil springs 77 disposed between the piston and a shoulder 42 on the cylinder head 14 urge the piston 39 rearwardly. On pressing the lever 71 down upon the cap of the slide valve 58 the O-ring 64 seals over the vent 65, the exhaust orifice 66 is closed and pressure air flows through ports 68, 67 to the piston chamber to drive the piston 39 forwardly. On release of the lever 71, the valve is loaded by a spring 61 so that an O-ring seals over the inlet port 63 and the inlet orifice is sealed, the exhaust orifice 65 being opened and the piston cylinder vented to atmosphere. A screw 84 threaded into the back of the piston cylinder co-operates with the piston and regulates the stroke thereof. A lock screw is provided to supplement the threaded frictional engagement of the cylinder head in the housing. In a modification one of the nipper implement levers is rigidly fastened to the cylinder head.

Title: Multifocal ophthalmic lens blanks and lenses and methods of making the same
IPC: G02C7/06
Filed: 1935-12-20
Abstract: 447,377. Spectacle lenses. HUBBELL, D. D., 82, North High Street, Columbus, Ohio, U.S.A. Dec. 20, 1935, No. 35343. Convention date, Dec. 20, 1934. [Class 97 (i)] A blank from which a bifocal &c. lens can be ground with the reading portion having prismatic power in any desired direction, is made from a main portion 1 having a substantially plane base 4 and a spherical upper surface 3, the centre of curvature cf which is displaced from the axis of the portion 1, so that the surface 3 is inclined to the base 4. A second portion 5, of the same glass as the portion 1 and of substantially the same outline, is formed with a deep recess 6 into which is fused a piece of glass 7 of higher refractive index than the pieces 1, 5. The surface 8 of the composite piece 5, 7 is ground to the same curvature as the surface 3 of the piece 1 and these two surfaces are placed in contact and the two pieces then fused together. The resulting blank, Fig. 9, consists of a piece of glass 7 of high refractive index embedded in glass of lower refractive index, the lower surface 9 of the piece 7 being part of the original surface 3 and therefore having a, known relationship to the base 4. A lens in which the reading segment has prismatic power of any desired orientation can be produced from this blank by suitably grinding its upper surface. For example, by grinding to the curve 10 of Fig. 10 a reading segment with prism base up is produced, while if the blank is ground to the curve 10 of Fig. 12, a reading segment with prism base down is obtained. The prescription curve for the finished lens is formed on the base 4.

Title: An instrument for the observation of the speed of aircraft or analogous purposes
IPC: G01P3/36
Filed: 1932-12-13
Abstract: 411,853. Aircraft speed-indicator. WALKER, J. H., 21, Lancaster Road, Hampstead, London. Dec. 13, 1932, Nos. 35348/32 and 5583/33. [Class 106 (iii).] In apparatus in which an optical system produces an image of the ground or other stationary object and a moving index device is synchronized with the image to determine the speed, the optical system is adjustable to ensure constant size of image despite variations of altitude or distance of the object so that direct readings of speed may be taken. The movement of an aeroplane may be observed from the ground. The lenses 2, 3 produce on the graticule 4 an image of the ground which may be viewed by the eyepiece 1, 7, the lenses being independently adjustable by a verge ring 6 according to the altitude as determined independently. The verge ring when rotated moves the holder 11 of the lens 3 vertically by means of a pin 12 on the holder engaging a cam groove in the tube 8 to which the ringis secured. The holder 13 of the lens 2 is similarly adjusted through the medium of a non-rotating tube 15 carrying a pin 8<c> which engages a cam groove in the tube 8, the tube 15 and holder 13 being connected by pins passing through longitudinal slots in the fixed guide tube 5. The moving index, by which the speed of the image is measured, is formed by a spiral line 26 on the edge of a rotating disc 25 mounted on a vertical shaft 29, the spiral lines being approximately at right angles to lines on the graticule which coincide with the direction of movement of the image. This condition is brought about by rotary adjustment of the upper part of the apparatus about the upper end of the fixed tube 5, the connection between the two including a spring ring 22 and a pointer 24 indicating the angular adjustment and the drift. The apparent radial movement of the spiral lines indicates the speed, the disc being driven at varying speed by an electromotor until synchronization with the image is obtained. The speed is regulated by control of the motor and by a centrifugal governor or brake, while a tachometer driven from the vertical shaft 29 through a horizontal shaft 36 indicates the ground speed directly. The index may be viewed by reflection.

Title: Improvements in magnetic core switching networks
IPC: H03K19/16
Filed: 1956-11-20
Abstract: 843,496. Circuits employing bistable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 20, 1956 [Nov. 23, 1955], No. 35501/56. Class 40 (9). [Also in Group XIX] The inputs to a logical circuit are each supplied from a winding on a first magnetic core connected in circuit with a winding on a second core such that switching of the first core induces current in the supply circuit to switch the second core whereas the simultaneous switching of all the second cores induces current in each supply circuit insufficient to switch the first cores but sufficient to provide an output. Fig. 2 shows an AND gate in which inputs IX, IY, IZ, are applied to windings on cores 12 of square loop material. The logical circuit comprises the core 22 supplied from three parallel branches including the windings 16 and 26 and the resistors 24. Switching of a core 12 in response to an input induces current in a winding 16 sufficient to switch the associated core 28 the high impedance of winding 26 preventing the flow of current through resistor 24 sufficient to affect the logical core 22. After the registration of inputs in cores 12 and 28 a clock pulse source IR restores all switched cores 28 and induces current in the windings 26 which does not overcome the coercive force of cores 12, and consequently meets low impedance, but is sufficient, when all outputs from the parallel branches are combined to switch the logical core 22. Core 22 is, therefore, switched in response to all inputs and no fewer. Restoration of cores 12 by source IA induces current in windings 16 which combine to restore logical core 22. In the EXCLUSIVE-OR gate of Fig. 3, the clock pulse source IR reads out the registration of inputs IX, IY, in cores 44 the outputs of which are cross-connected with the cores 47. If neither or both inputs are present cores 47 are undisturbed and restoration by pulse source IA produces no output in windings 50. If only one input is present one core 47 is switched by read-out of cores 44 and when reset by source IA gives an output. To increase the coercive force of cores 41 and 47 a bias is applied from source IDC. By connecting a winding on a core between earth and the junction of cross-connected windings 48 on cores 47 the additional core may be switched when both windings 48 are energized but remain undisturbed when only one is energized. Since AND and OR outputs are present the circuit comprises a binary half-adder. Fig. 5 shows a NOT gate in which a signal SB, if it occurs, is coincident with a clock-pulse IB and the registration in both of cores 86 is read out by source IR to act in opposition on core 84 which consequently gives no output. If a registration is given by the clock-pulse alone, core 84 gives an output. Restoration of cores 81 by source IA also restores core 84. Specifications 748,558 and 760,175 are referred to.

Abstract: 380,323. Loosening tobacco leaves. QUESTER, E., 141, W³llnerstrasse, Lindenthal, Cologne, Germany. Dec. 24, 1931, No. 35733. Convention date, Jan. 3. [Class 130.] The tobacco leaves are first passed through a loosening-device h, and the unloosened leaves are then separated from the loosened leaves by a device comprising two funnels a, b arranged one in front of the other, and in which the leaves are subjected to a current of air conveying the loosened leaves, together with dust and like impurities, into the second funnel b and through a conduit d to a sifting-drum m, for example as described in Specification 335,259, [Class 130, Tobacco]. The unloosened leaves fall through the funnel a into a container k, or on to a conveyer which carries them back for further treatment in the loosening- rolls h. Heavy foreign bodies are discharged into a chamber i on the funnel a. The current of air may be produced by a blast through a nozzle l, adjustable about a pivot, or by suction, and the action of the air current is varied by means of dampers /, g and an adjustable baffle p. The dust is carried away through a suction conduit n connected to the sifting-drum m, and the loosened leaves fall into a truck o or other conveying-device.

[Class 29.] Compression machines and systems. -A machine comprises a substantially cylindrical horizontallydisposed unit having evaporation and condensationspaces 1, 2 respectively provided with brine and cooling water tubes 11, 15 and separated by heat insulation 6, and a support G for the rotary compressor K and its driving motor M. The refrigerant vapour is discharged by the compressor through the pipe 17 into the condensation space 2, the lubricant entrained by the vapour being trapped in a pocket 31 from which it returns hrough the pipe 25 to the compressor. Surplus oil overflows through the pipe 32 and collects with the condensate at the bottom 18 of the space 2. From the condensation space the condensate together with some lubricant flows through the pipe 19 and a valve 40 into a chamber and thence through a pipe 21 into the lower part of the evaporation space 1. The valve 40 is controlled by a float 40<1> in a chamber 20 connected by pipes 41, 43 to the vapour and liquid or lubricant spaces respectively of the evaporator. By connecting the pipe 43 to the lubricant sump 26 of the evaporation space lubricant will be forced into the float chamber. The vaporized refrigerant passes through the tube 22 to the compressor suction port 34, while lubricant is withdrawn from the sump 26 through the pipe 28. The support G for the motor and the compressor is resiliently carried upon rubber cords seated in grooves 29 in the support. The brine-circulating pump 45, Fig. 5, and its motor m may be housed in an end cover of the unit, instead of being secured to the cover as in Fig. 3.

Title: Improvements in or relating to compressors for gas turbine jet propulsion engines
Inventor: PETRIE JAMES ALEXANDER
IPC: F01D5/22
Filed: 1964-09-04
Abstract: 1,065,278. Axial-flow compressors; compressor blades. ROLLS-ROYCE Ltd. Sept. 4, 1964, No. 36436/64. Headings F1C and F1T. In an axial-flow compressor for a gas turbine jet propulsion engine, the radially outer ends of the first stage stator blades are attached to the casing and the radially inner ends are disposed adjacent an abutment mounted on the rotor whereby axial movement of the stator blades is restricted. The compressor shown comprises first-stage stator blades 26 brazed or welded at their outer ends into slots in the casing 16 and brazed or welded at their inner ends into a ring 50. An annular abutment 52 on the ring 50 has a small axial clearance from an annular abutment 53 on the outer race of a ball bearing 54, the inner race being fixed on a rotor hub 20. Inlet guide vanes 24 carry the outer race of the front bearing 23 of the rotor, an annular abutment 7 on the outer race being disposed upstream of an annular abutment 8 on the rotor. Should a bird strike the inlet guide vanes 24, their resultant axial deflection is limited by the abutment 7 coming into contact with the abutment 8. The number of the vanes 24 is increased beyond the usual number and their leading edges are sharpened to cut the ingested bird into small pieces, whereby subsequent blades suffer less damage. Similar provision is made in the case of the stator blades, which are reduced in chord so that they retain their standard profile and space chord ratio despite their increased number and their sharper leading edges. The reaction of the pieces of bird on the stator blades 26 causes them to move forwardly until abutment 52 abuts the abutment 53 to limit the movement. Abutment 53. and the outer race of the bearing 54 then stop rotating. Each rotor blade 25, 27 is fixed to the rotor by a dowel pin 34 which is a close fit instead of the usual loose fit allowing the blade some freedom to roll. In addition, the abutting faces of adjacent blade roots are serrated to lock the rotor blades together to resist deflection in a circumferential direction. Adjacent blades are interconnected by aerofoil struts 37, 51. Rotor blades 25, 27 and, it may be, stator blades 28 are of titanium.

Title: Process for the production of pregnanolones
IPC: C07J75/00
Filed: 1934-12-24
Abstract: Pregnanolone and allo-pregnanolone are prepared from the corresponding 3-hydroxy bisnorcholanic acids by a process which comprises converting the acid into an ester, preferably a methyl ester, reacting on it with a Grignard reagent, transforming the reaction product into the corresponding secondary-tertiary carbinol, dehydrating the carbinol, and oxidizing the unsaturated compound obtained.  The 3-hydroxy group may be protected during the series of operations by esterification etherification, or halogenation.  The preferred method of dehydrating the secondary-tertiary carbinol is to heat with glacial acetic acid and distill in a high vacuum, and the preferred oxidizing agent which is used in the following step is ozone.  In examples: (1) the methyl ester of 3-hydroxybisnor-allocholanic acid acetylated on the hydroxy group is treated with phenyl magnesium bromide, the reaction product distilled with steam and the non-volatile portion boiled with alcoholic potassium hydroxide.  The aromatic carbinol so obtained is boiled for several hours with glacial acetic acid and then distilled slowly in a high vacuum.  The unsaturated secondary alcohol produced is treated with ozone in chloroform solution and the ozonide decomposed with water.  The hydroxy ketone C21H34O2 is thus obtained; (2) The methyl ester of 3-hydroxy-bisnor-allocholanic acid is treated as described in example (1) without protection of the 3-hydroxy group.  The same product, i.e. allo-pregnanolone-20 is obtained. The methyl ester of 3-hydroxybisnoncholanic may be similarly treated to yield pregnanolone-20.

Filed: 1964-09-09
Abstract: 1,072,159. Heating and cooling systems; radiator filler caps. LA PUBLICITE FRANCAISE. Sept. 9, 1964 [Nov. 13, 1963], No. 36991/64. Headings F4S and F4U. In a system for cooling the I.C. engine of a vehicle and heating the air within the vehicle, a thermostatically controlled valve e remains closed whilst the temperature is below 70-80 C., the water by-passing the radiator R through a pipe f. An open-ended venting conduit 1 is provided to allow for air displacement whilst filling the system when the valve e is closed, the conduit 1 branching from an outlet pipe d below the valve and terminating within the filling neck 2 of the radiator. Within the radiator cap 6 is mounted a spring 5 carrying a valve 4 which normally closes the end of the conduit 1 when the cap is in position. Any circulation through the radiator whilst the engine is warming up is thus avoided and heat for an interior air heating radiator S is more quickly available. In a modification, Fig. 2 (not shown), a radiator cap carrying a pressure and a suction valve has in addition a bellshaped auxiliary valve (25) which is spring- urged against a seating pad (26) in order to close off the chamber 27 and the end of the venting conduit when the filler is in place. In a further form similar to Fig. 1, the overflow pipe in the filler neck has a spring-closed valve with a permanent vent aperture (25).
