Title: Improvements in automatic couplings for vehicles
IPC: B60D1/04
Filed: 1937-12-17
Abstract: 485,368. Automatic couplings for vehicles. MORRIS COMMERCIAL CARS, Ltd., ROSE, P. G., and LEEDING, E. J. Dec. 17, 1937, No. 34943. [Class 103 (v)] In an automatic coupling for vehicles of the kind in which a pivoted hook 1 on one vehicle is adapted to be swung down to receive or release a draw-bar 11 on the other vehicle and to be raised by the draw-bar into a coupling position, in which position the hook is locked by a spring-loaded locking-member 13, the lock 13 is also adapted to serve as a closure for the mouth of the hook and thus prevents accidental release of the draw-bar. In the construction shown, the hook 1 has a general U-shape, and the inner or forward limb 1a thereof is engaged by the locking-member 13, which is constituted by a sliding plunger pressed rearwardly by springs 18. In effecting a coupling, if the hook is initially in its downward position, the limb 1a will force the plunger 13 inwardly and then be retained by the plunger being projected outwardly by the springs 18, whereas, if the hook is already in its upright condition, the draw-bar 11 will push the plunger 13 inwardly without actually disengaging it from the limb 1a. For uncoupling purposes, the plunger 13 can be drawn inwardly by operation of a lever 19 under the control of the driver. In a modification, Fig. 7, the sliding plunger 13 is replaced by a lever 23 pivoted at 24 under the influence of a controlling spring 25.

Patent GB-488095-A (GB)
Title: Process for the production of crease-proof textile material
IPC: D06M11/38
Filed: 1936-12-29
Abstract: Cellulose-containing textile materials except cotton are rendered crease-resisting and highly resistant to swelling by treating with a swelling agent, allowing to remain for some time in the swollen condition, the swelling agent removed by washing, and the material treated with formaldehyde at 90-160 DEG  C. in the presence of an acid-reacting catalyst; in the case of cotton, the swelling treatment is a mercerizing treatment, the cotton being either allowed to shrink and then stretched to beyond its original length, or is mercerized whilst stretched to just below the breaking limit.  Preferred swelling agents are soda or potash lye used at elevated temperatures. In an example, viscose yarn is desized, washed, dried and swollen for 5 mins. with caustic potash solution, washed, soured and dried; it is then impregnated in a formaldehyde solution containing aluminium thiocyanate, dried and heated to 118-120 DEG  C. for 20 mins.

The adjusting ring 4 is actuated by a lever 9 to focus the objective, and is coupled by gear wheels such as 13 to the rotary wedges 2, 3 so that they turn in opposite directions to adjust the telemeter.

Abstract: 871,567. Automatic temperature-control systems. STEGHART, F. L. F. Feb. 22, 1957 [Nov. 17, 1956], No. 35856/60. Divided out of 871,562. Class 38 (4). In an electronic automatic temperature control system temperature variations are detected by a two-part element, one part of which is sensitive and the other insensitive to temperature changes, the element forming part of, but being located remotely from, the remainder of an A.C. bridge circuit to which it is connected by three leads. In the arrangement described, which is identical with that described with reference to Fig. 4 in Specification 871,562, deviation of temperature from a desired value influences a temperature variable resistor 1 which, together with constant resistors 4 and 160, is connected to the remainder of an A.C. bridge circuit, which is located elsewhere, by three leads (shown dotted), one of which is earthed. The resulting output of the bridge circuit, balance of which is independent of the length of the leads, is applied through a transformer 163 to a phase-sensitive discriminator, the direct voltage output of which, through an electronically-operated relay circuit, runs a temperature-regulating motor 38 in the appropriate direction to correct the temperature. A potentiometer 40 operated by motor 38 applies rate feed-back through a condenser 52 to introduce an integral component of control. A disconnecting link 164 facilitates balancing of the phase discriminator.

Abstract: 850,886. Electromagnetic couplings. EATON MANUFACTURING CO. Nov. 18, 1958 [Feb. 19, 1958], No. 37005/58. Class 35. A liquid-cooled eddy current coupling has a field rotor 12 in two annular shaped parts 31, 32 secured together by screws 33. Part 31 is connected to a hub 34 attached to shaft 14 which can rotate in bearing 23 mounted in boss 21 of end-wall 17. Winding 40 is mounted in cavity 41 between the two parts 31, 32 of the field rotor and its leads 42 are carried through conduit 43a, 43b. The parts 31, 32 carry axially extending projections 37, 38 alternating in interdigitating relation (Fig. 3) which projections form a series of pole members separated by airgaps 36 around the periphery of field rotor 12. Inductor rotor 13 has an annular drum portion 45 extending around the field rotor 12, the drum portion being mounted on a disc 46 attached to shaft 15 by a hub 47. The internal wall 50 of the drum portion 45 has transverse grooves 51 for conducting the cooling liquid through the system. There may be two sets of grooves 51a, 51b inclined mutually at 90 degrees and to the rotation axis at 45 degrees. They cross near the mid-plane of the field rotor 12 and have common starting points 53, 54 on opposite edges of the drum portion 45. The number of grooves and the number of pole pieces are preferably not exact multiples of each other. Cooling liquid such as water is supplied to the grooves 51 from passage 48 between the rotors into which it is introduced through a series of openings 58 from pocket 57 in the inductor rotor 13. Pocket 57 is supplied through nozzle 61 supported in the end wall, the nozzle projecting into the pocket through an annular slot 60 in the inductor rotor. Normally the liquid passes through by-pass 65 (Fig. 1, not shown) but with a heavy load the temperature of the cooling liquid collecting in chamber 26a of housing 11 rises above the predetermined operating temperature and valve 64 (not shown) is opened by pressure transmitted from temperature-sensitive bulb 66 (not shown) in chamber 26a, thus allowing addition cooling liquid to pass to nozzle 61. The cooling liquid is discharged through outlet 70.
