Title: Improvements in or relating to honing methods and devices
IPC: B24B33/08
Filed: 1939-06-06
Abstract: 529,681. Honing cylinders. MICROMATIC HONE CORPORATION. June 6, 1939, No. 16584. Convention date, Feb. 23. [Class 60] In honing cylinders the last strokes of the hone are not accompanied by rotation so that the final scratch marks are parallel to the axis of the cylinder. The expanding hone is so constructed that all parts of the cylinder are treated during the final stage and the machine is designed to effect the change in operation at a pre-determined time and to stop at the end of the cycle. The segments of the expanding hone have projections 84, 85, Fig. 6, alternating on opposite sides the projections and recesses in adjacent segments overlapping at all stages in the expansion. The segments are secured in carriers 78 received between projections 68, 69, Fig. 3, on a sleeve 67 having a driving connection through balls and recesses 70, that permit slight universal movement, with a sleeve 38. The segments are expanded by pins 82 and a wedge core 72 having a ball and socket connection at 75 with an axial rod 65. Garter springs 81 tend to collapse the hone. The hones are circumferentially grooved at 89. A modified hone for use in blind bores has the segments suspended by pins 103, Fig. 7, and expanded by pins 97, 99 engaging recesses in the carrier; flats 98 prevent the pins from turning, and a single garter spring 102 is provided. In a further modification also for use in blind bores the lower set of pins transmit movement to the segments through pivoted members so that the expanding pressure is applied close to the bottom edge. The expansion is effected by fluid pressure admitted at 26, Fig. 2 to a cylinder formed by sleeves 22, 24 mounted between ball thrust bearings 23, 29 so as not to rotate with the tool body 21 which has a driving-connection at 17 with the shank 16. Rotation of the piston 27 is prevented by pins and slots 36 which also limit its movement which is transmitted by a sleeve 34, pin 47, sleeve 46, pins 58, balls 55, nut 54, threaded sleeve 52, and pin 51 to the rod 65. A spring pressed ball 61 co-operates with recesses 59 to prevent unwanted rotation of the nut after adjustment has been effected. A spring 31 acts to return the piston 27. Rotational drive is transmitted from the body 21 to the sleeve 38 through balls and recesses 39, the balls being retained by a sleeve 41 moved down against a stop 42 by pins 43 forming a connection with a sleeve 44. The shank of the tool is connected to a piston rod 119 reciprocated by a fluid pressure cylinder 116 and rotated through gearing 120 driven from a motor through a clutch 122. A time switch 123 acts through a solenoid 125 to throw out the clutch after a pre-determined time causing the lap to reciprocate without rotation until stopped by a time switch 124 acting through a solenoid 126 on the valve 127.

Abstract: 111,876. Henslow, T. G. W. June 19, 1917. Syringes of the kind in which the spraying- nozzle barrel is provided with a compartment within which is arranged a cage or container adapted to receive disinfectants, insecticides, &c., and to be rotated by the passage of water through the compartment. The said cage or container comprises a number of compartments n, Figs. 2 and 5, that successively come under the influence of a stream of water passing through the barrel a as the cage or container rotates. The axis of rotation of the cage is at right angles to the flow of liquid, and the nozzle barrel extends tangentially from the cage compartment d. The cage is fixed on a spindle h mounted to rotate in an end wall of the compartment at one end, and in a removable bar or the like k, the ends of which fit into grooves in the other end of the compartment. Chemicals are introduced by removing a cap f and partly rotating a bladed plate o so as to uncover the cage compartments, after raising it so as to disengage recesses on the cover plate from projection on an end plate p, which is formed with openings corresponding with the compartments n. At the rear of each compartment is fixed a plate r, Fig. 5, against which the water strikes. The disinfectants &c. are preferably used as soaps in bar or lozenge form. When used as a hand sprayer the apparatus is held so that the chamber below the barrel and water is drawn in, as when using an ordinary garden syringe; when full the sprayer is turned over and the liquid forced out. The apparatus may be applied to war uses, such as for spraying trenches for the destruction of mosquito larvae, and for agricultural and horticultural purposes.

Title: Device for adjusting the level of brightness of vehicle headlamps
IPC: H05B37/02
Filed: 1976-04-23
Abstract: 1531026 Dimming systems for vehicle headlamps O WILJE 23 April 1976 [24 April 1975] 16686/76 Heading H2H The dipping system of a vehicle headlamp system is so arranged that when the system is switched from main beam to dipped beam, the dipped beam is illuminated immediately but the reduction in the illumination of the main beam occurs over a predetermined period. The main beam filament 7 of a vehicle headlight is energized when the dip switch 9 co-operates with a contact 8. During this time a capacitor 3 is charged over a diode 6. Movement of the dip switch 9 from the contact 8 to contact 9 causes illumination of the main beam filament 7 by way of transistors 1, 2 and the charged capacitor 3, the illumination gradually decreasing as the capacitor 8 discharges through the resistor 4, the rate of decrease being determined by the setting of the resistor 4, In a further embodiment a Zener diode is connected in parallel with the capacitor 3 whereby when the changeover of the switch 9 to the contact 10, the illumination of the main beam 7 drops instantaneously to an intermediate value before a gradual reduction thereof. In yet another embodiment the main beam 7 is always supplied by way of the transistor 2.

Title: Improvements in or relating to treatment of glass fibers
IPC: D06M15/507
Filed: 1953-06-17
Abstract: A film-forming material for treating glass fibres (see Group IV (c)) comprises a mixture or the reaction product of a polyester having free hydroxyl groups and an organo-silane having an unsaturated carbon-to-carbon linkage.  Hydrolysable groups in the silane react with hydroxyl groups in the polyester whereby a silane/polyester reaction product is formed with elimination of hydrogen chloride if the hydrolysable groups are chlorine and an alcohol if the hydrolysable groups are alkoxy.  Specified polyesters are polypropylene itaconate, polyethylene maleate and polyethylene maleate phthalate whilst specified silanes are diallyl diethoxy silane, triethoxy allyl silane, vinyl trichloro silane, divinyl diethoxy silane, vinyl triethoxy silane, vinyl trichloro silane together with beta-chloroallyl alcohol to form betachloroalloxyvinyl-silane, dimethoxy dicrotenyl silane, triethoxy methallyl silane and dichloro ditiglylsilane.  The polyester-silane combination may be diluted with an organic solvent (e.g. toluene or acetone) or dispersed in aqueous media containing ammonia before applying it to the fibres.  The coated glass fibres may be used in the manufacture of laminates (see Group VIII) using an unsaturated polyester as laminating resin whereby coupling occurs between the coating on the fibres and the unsaturated polyester.  The component of the unsaturated polyester may be maleic, fumaric, itaconic or phthalic acid and ethylene glycol, diethylene glycol or allyl alcohol and the polyester may be used in combination with butadiene or styrene. In Example 5, glass fibres coated with a reaction product of polyethylene maleate and vinyl triethoxy silane are distributed in allyl alcohol and the mass hardened by means of benzoyl peroxide.ALSO:Glass fibres in the form of yarns, strands or fabrics are made more receptive to colouring agents and resinous or rubbery material by treating them with a filmforming material comprising a mixture of or the reaction product of an unsaturated polyester and an organo-silane having an unsaturated carbon-to-carbon linkage.  The polyester-silane combination may be diluted with an organic solvent, e.g. toluene or acetone, or dispersed in an aqueous medium containing ammonia before applying it to the fibres.  Application may be made by dip coating, flow coating or roller coating followed by drying in air or in an oven heated to 150 DEG -450 DEG F.  Preferably application is made whilst the fibres are being formed, but if application is to be made to already formed fibres any previous coating or size is first washed off or burnt off, e.g. at 800 DEG F.

Filed: 1949-06-24
Abstract: 670,656. Rope conveyers. TUSTING, J. C., and OVERSTALL, G. June 21, 1950. [June 24, 1949] No. 16782/49. Class 104 (ii). [Also in Group XIII] In the drying of leather, hides &c. the skins carried on frames 58 are propelled continuously through a drying chamber 10 by a conveyer, and a second conveyer external to the drying chamber but passing transversely through each end of it has controlled intermittent movement, automatic means transferring the loaded frames from the external conveyer to the internal conveyer and, when the skins are dried, back to the external conveyer again. The drying chamber 10 has a pair of track rails 11, one at each side of the chamber and an endless chain 12 supported on sprockets 13 whereby it is driven, runs adjacent each track rail 11 and has horn attachments 14 at regular intervals, jockey wheels 15 and tensioning gear 16 being provided on the return run. An overhead runway 17 runs externally along both sides of the chamber 10, passing through each end of it and suspended from the runway by brackets 18 with runners 19 is an endless chain 20 having jockey wheels 21, driving sprockets 23 and tensioning gear. The internal conveyer chain 12 is driven continuously by a motor through shafts 28, 30, gears 31, 32, 33 and shaft 37 which drives the sprockets 13 through gears 39, 40, 39a, 40a. The external conveyer is driven from the other end of shaft 30 through a magnetic clutch 41 via sprockets 43, 44 and chain 45 driving a vertical shaft 48 which carries the sprockets 23 of the chain 20. Constantly driven stub shafts 49, 49a extending into chamber 10 carry transfer arms 52 each having pivotally secured thereto a cup-like member 52a connected by a rod 53 to an arm 54 pivoted at 54a and having a counterbalance 55 (Fig. 5). Some of the brackets 18 have carrier hooks 56 to receive bars 57 carrying the panels 58, each bar having runners 62 which travel on the tracks 11 when the frames are propelled through the chamber by the horns 14 of the chain 12. Each panel arrives in turn at the unloading end and the runners 62 move down ramped portions 11a and rest against stops 11b where they are picked up by transfer arms 52 which make one revolution in the time taken for the next panel to move into position and the panel is lifted so that bar 57 engages with a pair of hooks 56 of runway 17. The chain 20 is kept stationary during this operation through clutches 41 operated by cam-operated switches. As each frame is unloaded another frame is loaded on to the track rails by arms 52 operating in unison with those unloading. To prevent uncontrolled gravitational movement of a panel when its runners reach the ramps 11a each track has an arm 64 pivoted at 64a and supported near its free end by the plunger 65a of a dash-pot 65, so that the runners rest gently on the horns 14 in front as the plunger descends and are retarded so as to come to rest without shock against the runners of the preceding panel.

Title: Coincident-Current Memories
IPC: G11C11/06
Filed: 1967-04-13
Abstract: 1,150,985. Core stores. LITTON INDUSTRIES Inc. 13 April, 1967 [22 April, 1966], No. 17103/67. Heading G4C. [Also in Division H3] In a coincident current matrix comprising a storage core matrix and a driving core matrix, the cores of the latter being electromagnetically coupled to respective sets of storage cores of the storage core matrix by respective closed loop conductors, read out is by detecting voltage changes from an interrogated core induced into the coupled closed loop conductor. The change of state of the storage core being interrogated occurs during the change of state of the interrogating driving core through one of the steep portions of its hysteresis characteristic. In the embodiment of Fig. 1, driving cores 14, 16, 18 and 20 of driving core matrix 12 are biased by source IB and are adapted to be switched by coincident currents from sources 62, 64, 66 and 68 which generate magnetomotive forces in opposition to the biasing magnetomotive forces. A sense amplifier 70 is connected across the biasing source 60 and line 82A is used to sense changes of flux in driving core matrix 12. In order to interrogate storage core 53 in the storage matrix 10, control logic 80 sends a signal C to current source 30 and thereby to switching means 32A, 32B as well as to current sources 64, 68. Clock source 76 generates signal 300, Fig. 6A, to cause currents from sources 64 68 to switch the operating point of core 16 from 206 to 204, Fig. 5, resulting in a current pulse to be sent through the loop 24. Immediately afterwards clock sources 78, 74 are energized, clock 78 causing current pulse 302 to be sent to the column including core 53. Storage core 53 is thus interrogated and if it is in its " 0 " state it does not change its remanent state. However, if a " 1 " is being stored its remanent state is switched causing a signal to be generated in loop 24 and since the remanent state of the driving core is in the steep portion of the hysteresis loop, e.g. 210 at this point a voltage is induced back into the biasing line 82A. This induced electromotive force appears across bias current source 60, which pulse in combination with clock signal 304 from source 74 opens gate 72 and a read out signal is obtained therefrom. Signals 306A and 308A represent 1's and 0's respectively, Figs. 6C, 6D. A balancing core 69 and current source 67 may be connected in series with the biasing source 60 to cancel voltages due to core 16 being switched in which case line 71 is omitted and the waveforms obtained are as shown at 306, 308. In a second embodiment, Fig. 2 (not shown), a separate driving core is coupled to each row set of matrix 10 and a separate sensing line threads the driving cores in addition to the bias conductor, the sense amplifier being connected to the sensing line.
