IPC: H01H17/00
Filed: 1926-07-16
Abstract: 266,203. H³rlimann, R. July 16,1926. Flexible-pull actuation. -A switch for lighting installations and the like comprises a rotary contact device adapted to be actuated at a distance by means of one or more flexible pull elements connected to a spring-controlled pin or like floating member co-operating with a notched disc on the shaft of the contact device so as to move the device one step forward every time one of the pull elements is operated. A cam disc 2, mounted on a shaft 2<a>, has a plurality of cams 24 and a peripheral groove receiving a number of pull elements 12, each connected to a spring-controlled pin 3 and communicating through flexible tubes 22, if necessary with the aid of spherical guiding elements 11, with its own operating push 10. The shaft 2a also carries a contact block 15a co-operating with spring contact arms 13, 14 and having insulating inserts 15. Any one of the pushes 10 can be depressed to rotate the disc a quarter turn and move the switch on, release of the push allowing the spring 4 to pull the pin 3 behind the next cam 24. Also, any push can be depressed to actuate the switch another quarter turn into the off position. The pushes may be located in different places and need not have flexible tubes, in which case the elements 12 are guided over pulleys. The switch is adapted for staircase lighting or for all cases where it is to be operated from different points.

Title: Automatic brake control for vehicles
IPC: B60T7/20
Filed: 1931-03-12
Abstract: 374,474. Brakes ; railway vehicles. JONKHOFF, H. W., 2A I, Berger Ufer, Dusseldorf, Germany. March 12, 1931, No. 18005/30. [Class 103 (i).] Applied by weight of vehicle and by backward pressure of tractor or relaxation of pull.-The body of a vehicle is suspended from the understructure in the manner of a pendulum whereby the brakes are automatically applied by relative movement of these parts on inclines or when the vehicle tends to over-run the tractor vehicle. The structure 1 carried by bogies 3a, 3b, capable of longitudinal movement against the action of springs 12, supports by links 10, a platform 2 carrying the vehicle body. A lever 4 pivoted to each bogie is connected by a cable 6 to the brakes. If by reason of the braking of the tractor vehicle the drawbar 11 together with the bogie 3a is pushed rearwardly compressing one of the springs 12, the lever 4 is pressed against a spring stop 5 on the platform 2 and the brakes are thus applied. In descending a hill, the platform swings forwardly on the links 10 by gravity action and thus applies the brakes and it is necessary for the tractor to pull on the draw-bar 11 to release them. The brakes on the rear bogie are not applied in these circumstances except by the push of a second trailer, transmitted to the rear draw-bar 11. In ascending a hill the platform 2 moves rearwardly but the rear stop 5 does not engage the rear brake lever 4 to apply the brakes by reason of the lag of the rear bogie 3b but if the vehicle tends to run backwardly, this bogie moves inwards relatively to the platform 2 so that the lever 4 is actuated and the brakes applied. The stops 5 can be set to a position by screwed rods 9 to render the brakes inoperative.

Patent GB-563184-A (GB)
Title: Improvements in processes for preparing nicotinic acid amide
Filed: 1942-12-22
Abstract: Nicotinamide is prepared by partial hydrolysis of 3-cyanopyridine with an aqueous solution of alkali sufficient to produce a larger proportion of nicotinamide than of nicotinate, but insufficient to produce complete hydrolysis.  Alkalis specified are ammonia, alkali hydroxide, carbonate, bicarbonate, borate, acid phosphate, nicotinate, acetate or other organic salt, alkaline-earth hydroxides, trimethylamine and triethylamine.  In examples, 3-cyanopyridine is refluxed with water and sodium hydroxide, carbonate, tetraborate, bicarbonate, acid phosphate, nicotinate or acetate.  The product is evaporated to dryness and extracted with acetone or ether to separate nicotinamide from the insoluble sodium nicotinate.  The extract is boiled with carbon, filtered, and crystallized.  Alternatively, the cyanopyridine is heated under pressure with ammonia water or is heated on a steam bath with lime water or water and triethylamine or refluxed with water and sodium hydroxide in the presence of isopropenol or acetone and methanol.  The product is evaporated to dryness and either extracted with acetone to recover the amide or washed with benzene to remove the nicotinate.  In a further example, 3-cyanopyridine is dissolved in hydrogen peroxide, and ammonia water added.  Reaction is completed by heating to 45-50 DEG  C. Other oxidizing agents may be used in place of hydrogen peroxide.

Title: Improvements relating to electric switches, particularly for controlling the currentto electric cooking and heating apparatus
IPC: H01H25/06
Filed: 1935-06-26
Abstract: 447,456. Regulating-switches; locking switches. REED, J. P., c /o Tubes, Ltd., Wheelwright Road, Birmingham. June 26, 1935, No. 18276. [Class 38 (v)] A regulating-switch, in which a rotary contact arm c moves over contact studs b connected to resistances or tappings of a transformer, is associated with a tumbler or other switch l in such a manner that the circuit must be broken at the switch before the contact arm c can be moved from one stud to another. The contact arm c is carried by a hollow spindle e which is driven by a spindle f carrying a handle g. The spindle f can move longitudinally relatively to the spindle e, and the engagement of a pin h carried by the handle in one of a circle of holes i normally prevents rotation of the handle. The dolly and base of the tumbler switch are respectively connected to the spindles f, e, and the switch is operated by their relative movement. To operate the arm c, the handle g must therefore be first moved outwards, and this movement actuates the tumber switch into its "off" position. The handle can then be rotated into its desired position and the circuit is finally closed again by moving the handle longitudinally back to the left. Specification 423,172 is referred to.
