Abstract: 958,663. Switches held set and freed mechanically; keyboard switches; electrically-released switches; electromagnetic switches. TELEPHONE MANUFACTURING CO. Ltd. July 4, 1961 [July 6, 1960 (2)], Nos. 23558/60 and 23559/60. Heading H2B. An operating member, e.g. the push-button of a switch, is latchable in one position, the latch comprising a relatively movable pin and closed track, there being provided in addition a second track which is alternatively engageable by the pin so that " push-push " and " push-tolock " operation are obtainable as alternatives. One track is shown in Fig. 2 (23558/60), the pin 6 being so mounted as to be urged down on to the track and to the left. The step 10 thus prevents the pin from moving into the left-hand leg 9 of the track when moved upwards from the position shown. The track may be carried by the push-button and the pin by the fixed part of the switch, or vice versa, and in the first case the track may be used as a cam to actuate the switch contacts. An indicator lamp may be mounted on the fixed part and within the push-button which has a transparent cap. Several push-buttons may be arranged in a group and interlocked by a bar 13 so that operation of any button releases a previouslyoperated button. The second track comprises a shoulder 15 on which the pin 6 rests in the depressed position, Fig. 4 (23559/60), not shown, lateral movement of the bar 13 by the pin of another button moving the pin 6 from shoulder 15 through a passage 12 to release the depressed button. In a modification, Fig. 1 (23559/60), not shown, the second track is formed separately from the first track and the pin is selectively positioned to co-operate with the desired track depending on whether the button is to be used in a group or singly, respectively. The button may be operated by a pulsed electromagnet. Specification 958,664 is referred to.

Title: Improvements relating to motor vehicles with pneumatic springing
IPC: B60G21/10
Filed: 1959-07-09
Abstract: 869,984. Preventing lateral canting. DAIMLER-BENZ A.G. July 9, 1959-[July 9, 1958], No. 23652/59. Class 108(2). A motor vehicle having pneumatic suspension springs controlled by height-control valves, has a stabilizing system, to compensate for tilting, controlled by a valve which is operated by the steering mechanism of the vehicle. When the steering wheel 10 is turned in a counter clockwise direction, a rod 18 is moved toward a piston valve 19 (part only shown in Fig. 2) which is formed with an annular groove 33 in which is a radially resilient annular spring 35 formed with a slit 34. Due to the friction of the ring 35, the piston valve 19 is moved by the rod 18 until it meets an abutment 36 in the housing 11. The piston valve 19 immediately opens a supply duct 25 and closes a discharge duct 26 so that air flows from a reservoir 9 through ducts 8, 25, 27, 28 to the springs 12. A second piston valve 20 similarly mounted on the rod 18 does not change its position and the spring 35 inside it slides off a conical transition part and on to a reduced diameter part 18<SP>11</SP>. If the wheel 10 is turned further in the counter clockwise direction, the piston 19 stays in the same position as the rod 18 moves through it, overcoming the friction due to the spring 35. When the return movement of the steering wheel begins, the rod 18 immediately moves the piston 19 from any position reached, so that the supply duct 25 is closed and the discharge duct 26 is opened. The pressure in the springs 12 is relieved and the vehicle is in the normal position when the body leaves the curve. A similar operation occurs when the wheel 10 is turned in a clockwise direction. The stabilizing system may be combined with a main springing system using helical or other springs.

Abstract: 1,177,109. Data processing. GENERAL ELECTRIC CO. 23 May, 1967 [25 May, 1966], No. 23875/67. Heading G4A. In response to a request signal therein, processors and peripheral subsystems generate an information set and a signal indicating the type of request, the information set being passed to a peripheral snbsystem or processor respectively via a memory having different groups of positions for information sets associated with different types of requests. Input-output controllers (each controlling a plurality of input-output units) communicate with processors to request programmes by sending an information item and an indication of the programme type to a memory controller for storage in an associated memory. This memory has, for each input-output controller connected to it, locations for five information items for each type of programme which could be requested, a stored count indicating, in the case of each programme type, which of the five locations is to receive an item next. The stored indication of programme type required, and a stored indication of the identity of the input-output controller originating the request, are responded to by the memory controller to request an interrupt of one of the processors. When the interrupt is granted, the requested programme is executed utilizing the corresponding information item from the memory. The stored counts are incremented and decremented on storing and read-out of the information items. The identity of the inputoutput unit concerned may also be stored by the memory controller. Conversely processors may initiate communication with input-output units via a memory controller the latter supplying to the inputoutput controller concerned an information item or items specifying the operation to be performed by the input-out controller, the identity of the input-output unit concerned, the operation to be performed by the latter, and the quantity of data involved.

Abstract: 510,643. Weight motors. NOETH, J. J., and HUMMEL, F. E: Aug. 17, 1938, No. 24266. [Class 10] [Also in Group VI] A time-controlled 'mechanism, described as applied to an egg-boiler, comprises a vessel 10, a hollow standard 11 rectangular in section, an egg-holding basket 12, a chain 13 running over a sheave 15 and connected at its ends to the basket 12 and a rack 16; and a weight 14 slidable in the standard and connected to the chain 16 by a link 22 which permits the rack teeth to ride over a pinion 20 when the weight is raised. A vertically adjustable stop bar determines, the height to which the weight 14 may be lifted, and therefore the time taken for the rack 16 to become disengaged from the pinion 20. The pinion is connected through a gear train to a slow-running motor 21 of the induction type so that the drop of the weight is uniformly checked. The motor switch comprises a pair of spring-urged sliding contacts 40 in the mounting plate 30 of the motor, and a contact plate 43 carried by a lever 44 having its lower end adjustably secured to a shaft 46 journalled in the plate 30. A spring tends to keep the switch open. The switch is automatically closed by a shoe 53 on the shaft 46 riding on the side of the rack 13 and rocking the shaft 46. The switch opens when the shoe leaves the top of the rack, i.e., when the rack disengages from the pinion 20 to allow the weight 14 to lift the basket 12 from the water. The motor 21 is carried on the mounting plate 30 which has integral lugs 33, 34 which project through an opening 35 in one side of the standard and are secured by screws passing through the opposite side of the standard. The lug 34 has a spring 34a which serves to check the rack 16 prior to its engagement with the pinion 20. The mounting plate also has a portion 37 fitting in the opening 35 in the standard. The motor and switch unit is thus removable from the standard after the securing screws have been withdrawn.
