Patent GB-265178-A (GB)
Abstract: 265,178. National Cash Register Co., (Assignees of National Cash Register Co.). Jan. 29, 1926, [Convention date]. Cash registers printing on inserted material.- The effectivity of the machine release keys is controlled by the presence or absence of an inserted slip the feeler of which is connected with a linkage conveying the key movement to the machine-locking means. A lever 7 carries a stud 6 normally blocking a spring-urged lever 4 connected to the locking-pawl 3. The other arm of the lever 7 is connected by a pair of toggle links 23, 24 with a lever 16 pivoted at 15 and carrying a feeler 17 for the slip 27 inserted between guide-plates 19. The toggle joint 25 is linked to a lever 14 also pivoted at 15 and controlled by a lever 10 underlying pins 9 on the release keys 8. If no slip is present, the rocking of lever 15 results only in the upward straightening of the toggle links owing to the feeler meeting with no resistance in its travel. If a slip is present, however, the feeler is stopped and the resistance between lever 4 and stud 6 is overcome in the downward straightening of the toggle so that the machine is released.

Title: Improvements in and relating to the oxidation of organic compounds
Inventor: TAYLOR ARTHUR WILLIAM CHARLES
IPC: C07C51/255
Filed: 1957-08-23
Abstract: A process for the production of orthophthalic or isophthalic acid comprises oxidizing the corresponding toluic acid or formyl toluene in the presence of orthophthalic anhydride in the liquid phase by means of oxygen or ozone in the presence of an oxidation catalyst in the substantial absence of halogen while continuously removing water of reaction as vapour.  The reaction preferably takes place at about 200 DEG C. using a molar ratio of anhydride to acid or aldehyde of 1 : 2 to 6 : 1 in the presence of cobalt or manganese acetates.  The phthalic anhydride may be added as such or formed in situ.  When the meta isomer is used isophthalic acid may be filtered off from the hot reaction product, when the ortho isomer is used the hot reaction product may be hydrolysed with water to give phthalic acid.

Title: Improvements relating to motor-vehicle clutch controls
IPC: F16H63/44
Filed: 1957-08-23
Abstract: 825,685. Clutch control. DAIMLERBENZ A.G. Aug. 23, 1957 [Aug. 25, 1956], No. 26727/57. Class 80 (2). A motor vehicle having an hydraulic clutch followed by a separating clutch operated during gear-shift by power such as engine suction, has means for automatically increasing the engine speed by increasing its fuel supply temporarily during gear shift provided the road speed is above a predetermined value (15 K.P.H.). This prevents shock on downshift due to the otherwise excessive fall in engine speed. Operation of the gear lever closes a switch 19 thereby energizing an electromagnet 20 which operates a valve to disengage the clutch and, if the road speed is above the predetermined value, energizes an electromagnet 13 which moves a member 12 to turn a lever 4, fast on the shaft 2 of the usual engine throttle 3, through a small angle to open the throttle. On completion of gear shift the lever 4 is returned by a tension spring 7. A projection 8 on the throttle lever 4 is free to move in a slot 9 in a lever 5 freely pivoted on the throttle shaft 2 and connected to the accelerator linkage 6. If the road speed is below the predetermined value a switch 22 on the speedometer 21 is closed to energize a relay 23 which opens a switch 24 in the circuit to the electromagnet 13.

[Also in Groups I and XL (b)] In a device for interposing a pre-determined delay between the receipt of an impulse from a plant and the operation of a photo-electrically controlled hoeing machine, a continuously rotating wheel is driven from a shaft 47 geared, to the driving wheels of the machine. The edge of the wheel is grooved and a number of small cylindrical elements 83 which may be engaged frictionally in the groove and are prevented from rotating with the wheel 82 by a star wheel 84 normally held by a pawl 87. Energisation of an electromagnet 88 by receipt of an impulse from a good plant lifts the pawl from the star wheel so that one of elements 83 is released. The element is then carried around on the periphery of wheel 82 operating successively microswitches 91 and 92. The time taken for the element to reach the switches determines the delay in clutching in the hoe. The position of the switches round the periphery of the wheel may be adjusted by cam gearing 96, 103 extending to knobs at the exterior of the casing. Specification 590,598, [Group I], is referred to.
