Title: Improvements in or relating to machines for levelling the bottoms of boots or shoes
IPC: A43D89/00
Filed: 1937-02-25
Abstract: 491,082. Levelling shoe bottoms. UNITED SHOE MACHINERY CORPORATION. Feb. 25, 1937, No. 5638. Convention date, Feb. 27,1936. [Class 17 (i)] In a machine of the kind described in Specification 269,114, [Class 17 (i)], having a shoe support including a toe rest and a rockable last pin, a saddle for holding a shoe on the support and means for forcing the saddle against the shoe bottom, a locking device is connected with the last pin to allow it to rock towards the toe rest while the saddle is being forced against the shoe, but to prevent rocking movement thereafter in the opposite direction during the levelling operation. As described in the prior Specification, the saddle 28 is connected by springs 30, 48, on each side with parallel arms 32 of a hand lever 34 each linked to a lever 58 having a depending arm 59, the two arms being connected by a pin 62. The last pin 22 is rocked by a link 26 connected by a pin 84 with a link 66 slotted to slide on the pin 62 and carrying a member 68 which can be turned up to engage the pin 62. On the pin 84 are pivoted four pawls, two on each side of the link 26, the ends of which are urged against teeth on a plate 78 secured to the heel post 14. The springs 30 engage spiral grooves in members 36, 38 at the ends of each spring, and one of the lower members has an arm' on which is a pin 94 engaging a curved rib 92 on the end pawl, which pawl also carries a pin 98 co-operating with the tails of the other three pawls. When the handle 34 is raised to release the saddle at the conclusion of the levelling operation, the pin 94 retracts the pawls. If the saddle is not to be used, and the shoe jacked by the last pin only, the saddle is usually swung forwardly and draped over the hand lever. In this position, also, the pin 94 holds the pawls away from the plate 78. In addition, a latch 104 may be swung up to engage a shoulder 106 on the end pawl positively to hold the pawls out of action. Specification 447,683 also is referred to.

Abstract: 1,207,992. Strip-perforating machines. PURDY & McINTOSH (ELECTRONIC DEVELOPMENTS) Ltd. 1 Feb., 1968 [6 Feb., 1967], No. 5642/67. Heading B6W. When preparing a perforated tape for controlling a composing-machine, at the end of each line the operator decides whether thin spaces are to be added, and if so punches an "add thin space" signal (binary value 40) followed by "return" (2) and "elevate" (8) signals, the tape having a 6-bit code. The tape is then run in reverse through a combined readrecord unit 10 comprising a reading head 20 sensing only channels 1-5 and a punch 12 aligned with channel 6. The reading head senses the "add thin space" signal as 8, giving a sequence 8-2-8 or 8-2 only. The signals 2, 8 are decoded in a matrix 22 and emerge on outputs 24, 28 connected to three-stage shift registers 30, 32 and AND gates 34, 36, in one case through an inverter 38. For adding spaces, a flip-flop 40 is set to open a gate 42, whereupon a spaceband signal (4) on line 26 operates the punch. Otherwise the flip-flop is reset and the gate closed.

Abstract: 633,866. Gun aiming mechanism. LANDUCCI, F. A., NICHOLLS, K. H., and LEES, D. M. Feb. 26, 1948, No. 5722. [Classes 92 (i) and 92 (ii)] Means for aiming guns on unstable platforms comprises a mounting with elevating and training means 18, 19 under power control and a gun 9 on the mounting itself capable of universal movement under power control, the gun and mounting being stabilized. by a gyroscope 4 on the mounting which operates the power controls 16, 21 and has precessing torques applied to it by a joy-stick 23 to move a line of sight 15 (optical, radar or searchlight) to follow a target and apply to the gun by power means 12, 14 angular deflection in training and elevation to aim at a future target position. As shown, an optical telescope 7 and the gun 9 are carried by the same stabilized mounting, but the sight and gyroscope, together with a dummy gun, can be mounted separately for control of a distant gun actuated from the dummy gun. The movements about axes C, D of the gimbal frames of the gyroscope 4 spinning about axis S are conveyed by linkages 22, 17 respectively, to servo control valves 21, 16 for the motors 19, 18, connections 7B, 71 to the universally-mounted telescope 7 being provided to eliminate lag. The precessing torques applied to the gyroscope through joy-stick 23 operate through frames 24, 28 on torsion springs 26, 30 and the angles of precession, which are proportional to the angular velocities of the sight line movement in following the target, are conveyed to the gimbal-mounted gun through linkage 34, 37, hydraulic power cylinders 12, 14 and frames 12A, 14A, the time of flight being introduced through handle 41 acting through nuts 43, 42, slotted links 46, 44 and bell-cranks 47, 45 on calculators 48, 49 connected to differential gears 35, 38.

Abstract: 1,122,331. Printing apparatus. MOSSTYPE CORP. 9 Feb., 1966 [15 March, 1965], No. 5758/66. Heading B6C. A combined rotary proofing press and plate mounting machine comprises a hand-driven rotary cylinder couple 10 and 11 of equal diameters the plate cylinder 11 carrying a readily removable plate carrier 11c whilst the impression cylinder 10 mounts a master copy E of the matter to be printed by the plate. The machine is used for the mounting of printing plates-accurately registered-on to associated curved carriers for subsequent employment in a multi-colour rotary press in which the printing plates are mounted on the plate cylinders through the intermediary of readily removable carriers. The machine incorporates a viewing device 48, 49 with aligned registration marks 50, 51, 52A, 52B, 53, 54A, 54B and 55 which is slidable along a fixed bar 15. Through coupled rotary screws 30, 31 the plate cylinder is slidable relative to the cylinder 10. For mounting purposes the cylinders are apart and the plates necessary to reproduce the master copy E stuck on the cylinder 10 are adhered to on the carrier 11C temporarily secured to the cylinder 11 by the use of the device 48, 49. This device is removed for proofing, it being replaced by a handinking roller mounted on a carrier slidable along the bar 15. A sheet of transparent material is fixed over the copy E on the cylinder 10 and then the plate cylinder 11 is moved into contact therewith. Rotation of the cylinders through the hand wheel 24 subsequently effects an image on the transparent material which is readily assessed for registration. Fig. 9 (not shown) shows a machine in which the diameter of the plate cylinder is less than that of the impression cylinder and no removable carrier on the plate cylinder is provided. Instead the latter cylinder is removable from machine after the mounting and proofing of to plates and is used directly in the press.

Patent GB-790279-A (GB)
Title: Improvements in or relating to purification of amino compounds
Filed: 1956-02-28
Abstract: Glutamine and asparagine are purified by dissolving them in water, separating insoluble material, adjusting the pH to 5-10 and crystallizing the amide.  The process is particularly suitable where the impurities are glutamic acid and aspartic acid respectively. Solution in water may be achieved by warming, but if proteinaceous material is present it is preferable to use cold water containing a little mineral acid (e.g. at pH 3.1).  The insoluble material is filtered off (after cooling if necessary) and alkali (e.g. ammonia) added to increase the pH to the desired value.  Crystallization of the amide is facilitated by the addition of up to 60 per cent by weight (especially 30-50 per cent) of a C1-C4 alcohol or ketone, e.g. methanol or acetone.  Alternatively the amide is crystallized from water and the mother liquor treated with the alcohol or ketone to obtain a further crop of (impure) crystals; these may then be recycled. The preferred pH range for crystallization is 6-8 (especially 6-7 for asparagine).  Examples are given of the process.

Abstract: 1,210,863. Activated zinc oxide. H. F. A. TOPSOE. 9 Feb., 1968 [10 Feb., 1967], No. 6580/68. Heading C1A. [Also in Division C5] Activated zinc oxide for use in the desulphurization of industrial gases is prepared by heating shaped bodies of zinc oxide in an oxygen-free atmosphere initially of hydrogen at a mixture of hydrogen and up to 50% steam at an initial temperature above 300‹ C. and finally in an atmosphere of at least 50% steam at a temperature of at least 400‹ C., the temperature never rising above 550‹ C. The activation is preferably conducted in two stages, at 300- 400‹ C. and 400-550‹ C. respectively. The shaped bodies of zinc oxide may be prepared by forming and baking dry tablets of zinc oxide mixed with zinc stearate. Zinc oxide may also be suspended in water with cellulose derivatives e.g. methyl cellulose to form a paste which is extruded into cylinders and baked.

Filed: 1947-03-10
Abstract: 644,780. Compressors. BRADY, F. E. March 10, 1947, No. 6639. Convention date, Aug. 16, 1946. [Class 8 (i) [Also in Groups XXI and XXIX] An automatic air replenishing device for a fluid pressure system having a pressure tank 10 and a pump 12 therefor, comprises a housing 23 with a preferably flexible diaphragm 27 dividing the housing into vacuum and pumping chambers 34, 28 respectively, the vacuum chamber being connected to the suction side of the pump and the pumping chamber being in restricted communication at 40 with the pressure tank at the desired liquid level 21, and a normally closed check valve 41 to allow a charge of air to be drawn in to the pumping chamber when the diaphragm is moved on a partial vacuum being created in the vacuum chamber, and to allow air to be forced into the tank when the diaphragm moves in the other direction under spring tension when the vacuum is released, in order to maintain a desired liquid level in the tank and an air cushion therefor. Upon the liquid level in the tank 10 falling below a predetermined value (due e.g., to air absorption by the liquid), the pump 12 actuated by a motor 15 through a fluid pressure controlled switch 16 forces liquid into the tank via a pipe 11. The suction in the pipe 36 connected to the pump and to the vacuum chamber 34 pulls back the diaphragm 27 against the action of the spring 32. If liquid is below the desired minimum level (21), no extra air is supplied to the upper region 22 of the tank; but if the liquid is at or above this level, air enters the pumping chamber 28 past the valve 41 and is forced through the aperture 40 into the tank by the returning motion of the diaphragm 27 due to the suction in the pipe 36 lessening as the pump stops,

Title: Seat-belt system for motor vehicles
IPC: B60R22/48
Filed: 1973-02-12
Abstract: 1357087 Seatbelt system for motor vehicles FORD MOTOR CO Ltd 12 Feb 1973 [14 Feb 1972] 6762/73 Heading B7H A vehicle having at least one seating position equipped with a retractable seatbelt is provided with an electrical circuit including first switching means for sensing whether the seatbelt is in a retracted or extended position, second switching means for sensing whether or not the seating position is occupied, means for disabling the vehicle starter if the seat is occupied and the seatbelt is retracted, and means for disabling at least a portion of the electrical circuitry of the vehicle if the seat is unoccupied and the seatbelt is extended.  In a first embodiment (Fig. 1) a vehicle having a pair of seats equipped with retractable seatbelts includes switches S 1  and S 3  for sensing whether the seatbelts are retracted or extended and switches S 2  and S 4  for sensing whether or not the seats are occupied. If either seat is occupied and its seatbelt is not extended a relay 28 is energized which opens relay contacts 26 to disable the-vehicle starter. A warning buzzer 60 and warning light 62 are also energized. If the driver (or passenger) attempts to defeat the seatbelt system by extending his seatbelt in a position other than around his body, e.g. by buckling the seatbelt behind him or by tucking it into a seat cushion, the driver will initially be able to start and drive the vehicle. However when the driver or passenger leaves the vehicle the switches S1 and S 2  or S 3  and S 4  sense that a seatbelt is extended and the corresponding seat is unoccupied and disables part of the vehicle circuitry, e.g. disables the fuel gauge 54. Upon re-entry of the vehicle the driver (or passenger) must unbuckle or otherwise permit the seatbelt to take a retracted position if a fuel gauge reading is to be obtained. The circuit is also designed to be tamperproof. If any of the switches S 1  to S 4 , the warning buzzer 60 or warning light 62 are removed, this removal is detected by the circuit and again the fuel gauge 54 is disabled. In a modification (not shown) the vehicle starter is disabled instead of the fuel gauge under the above described conditions.

Abstract: 1474319 Extruding reinforced construction elements H MIYAZAKI 20 Feb 1975 [20 Feb 1974 15 Aug 1974 2 Oct 1974 3 Oct 1974] 7138/75 Heading B5A In the extrusion of material as a prop or beam reinforced longitudinally, and optionally transversely, by wires, bars, strip or mesh, the reinforcement is encased in the material in an extrusion die head outlet passage 7, Fig. 5, to which the reinforcement is delivered through a guide tube 11, Fig. 1, terminating at a convergent inlet 6 to the passage 7 and to which the material is delivered, from each of a pair of screw or piston extruders, along a passage 3a of a pair forming the branches of a Y configuration with passages 3, 3b, and 4 connecting with the passage 7, the passage 3b comprising a throttle 10 at its inlet, which acts to retard flow at the passage centre. In the Fig. 1-5 embodiment, a passage 3b is provided on each of opposite sides of the guide tube 11. The passages 3a are preferably inclined at preferably 45 degrees to the die head passage 3, 3b and 4. The reinforcement is delivered to and from the die head passages, respectively on conveyers 13, 14, and may be cut on the conveyer 14. To prevent flow of material upstream within the guide tube from its outlet in passage 7, the cross-sectional area between the inlet 6 and the guide tube i.e. at location "a", Fig. 5, is 1À1 to 2À0, and preferably 1-3 to 1À5 times that of the extrusion die passage 7, i.e. at location "c". The opposed downstream surfaces of the guide tube 11 at the inlet 6, are preferably at an included angle # of 60 degrees, and the surfaces of passage 6 are parallel thereoto. Where axially spaced and trasversely extending reinformenents are provided, as in the Fig. 1-5 embodiment, the extrusion passage 7 is more than three times, and preferably 4À5 times, that of the pitch "P", Fig. 5, of the transverse reinforcements, to prevent a greater thickness in the extrudate at the transverse reinforcement locations. The Fig. 1-5 embodiment relates to a solid section slab reinforced with both longitudinally, and transversely extending bars, but the extruded beam may also be of circular tubular section reinforced with wire reinforcement extending both longitudinally and spirally, Fig. 20 (not shown), and with the interior of the section being defined around a mandrel which extends through and out of the upstream end of the guide tube, where it is secured against axial displacement by attachment to a wire, and thereby also centred in the die passage by the pressure of the extruding material. In the Fig. 8 embodiment (not shown), a pair of mandrels are similarly arranged to produce the Fig. 13 section. The area of the die passages between the die and mandrels for producing the Fig. 13 or 20 section, is 3À25 that of the pitch between the helically or transversely extending reinforcements. The beam may also be of U or I section.
