Abstract: 1399411 Fluid pressure servomotor systems DAIMLER-BENZ AG 1 June 1973 [7 June 1972] 26193/73 Addition to 1333509 Heading G3P [Also in Division F4] In a pneumatically operated self levelling system for vehicle headlamps as in Specification 1333509, the control device comprises operating members disposed within a single casing 1 closed by covers 2,3. The casing 1 includes a partition 4 defining two compartments, the lower being divided into two chambers 9, 10 by a diaphragm 8, each connected to a partial vacuum via inlets 11,12 respectively. A control pin 17 secured to the diaphragm 8, passes through partition 4 and engages a diaphragm 13 in the upper compartment to form a two position valve therewith. The valve operates either to connect chamber 14 to chamber 15 and hence the atmosphere via bore 16, or to connect chamber 14 to a vacuum source via chamber 27, within piston-rod 26, and inlet 28. Movement of pin 17 is controlled by diaphragm 8 which responds to the partial pressures in chambers 9, 10 depending on the inclination of the vehicle body and its effects on the pressure control means which supply the chambers. Movement of pin 17 causes the valves formed by the pin and diaphragm 13 to operate resulting in movement of diaphragm 13 and its associated piston-rod 26 which causes movement of the headlamp. The casing 1 may be of metal or a plastics material.

Abstract: 1,065,252. Electrophonic instruments. SEEBURG CORPORATION. June 22, 1965 [June 26, 1964], No. 26251/65. Heading G5J. Operation of asingle key on keyboard 23 causes, the corresponding potential on the divider 20 connected across terminals 11, 10 to be applied to memory capacitor 27 which feeds amplifier 32 to adjust the current in transistor 36, thereby varying the charging rate of capacitor 37. Unijunction transistor 39 discharges the capacitor when its potential reaches a predetermined value, the resulting wave being fed to bi-stable flip-flops 43, 44 to produce output signals of half and quarter frequency at the terminals 47, 48. Diode gates 51, 52 are opened when transistor 58 is rendered conducting by a positive potential applied to the base over diode 56 by the closing of contact 54, operated with the associated key on board 23. Capacitor 57 discharges over resistors 65, 66 and 67 and the time may be increased by operation of switches 71, 72. The frequency increments between keys may be varied by adjusting resistor 13, and varying resistor 35 alters the tuning range. The switches operated by key 23, are connected so that when two keys are operated, only the lower potential is fed to memory capacitor 27.

In a nuclear reactor steam generator, water is normally circulated by a pump and in the event of failure of the latter, circulation is maintained by injection of steam into the system from an external auxiliary boiler. Over-heating due to decay energy is thereby prevented. The steam generating heat exchanger and the reactor core are mounted together within a pressure vessel and the steam and water.are pumped from the heat exchanger and are returned to it through an external steam-water drum. The auxiliary boiler is connected to the exchanger outlet header through a valve which is opened automatically upon pump failure.

Abstract: 279,636. Alfa-Laval Co., Ltd., (Funk N. E.). Oct. 29, 1926. Recovering waste lubricants.-Used lubricating oils are withdrawn from service, washed with water, separated from water and impurities and returned to duty, the washing and separating means being included in or connected with the main system for circulating the lubricant, and the process of regeneration being preferably carried out continuously. As shown in Fig. 1, oil from the main system fed by a valved pipe 15 is mixed with water from a valved pipe 16, and the mixture is delivered into a U-shaped chamber 19, formed by partitions 11, 12 in a tank 10 and adapted to be heated by a coil 45. Circulation of the mixture through pipes 22, 23 and the chamber 19 is effected by a pump 20, and an air injector 24, adapted to supply additional mixture from the chamber 19 through a valved pipe 25, may be provided to assist the mixing. The mixture continuously overflows the partition 11 into a chamber 27, and passes through a valved pipe 28 to a centrifuge 30, the water and impurities passing to a waste pipe 32, whilst the oil passes to a tank 37, from which it is pumped by a pump 39 through a colloidal filter 36 to a pipe 38, having a non-return valve 43, which returns it to the main system. In modifications, the pipes 15, 38 may lead respectively from the return side of, and to the delivery side of, the oil reservoir in the main system, or they may be branched from the return pipe of the main system on opposite sides of a valve in the return pipe; or the oil reservoir in the main system may be periodically drained into a second tank, and be refilled with oil which has previously been taken from the second tank, treated in the purifying apparatus, and passed to a third tank. The filter 36 need not be used, and, if necessary, a number of centrifuges may be used in series, in parallel, or in series parallel.

[Also in Division F2] A switch suitable, for example, for controlling a vehicle automatic gear change, of the kind comprising an " S "-shaped flexible blade S coupled at X to a speed-responsive member (P, Figs. 1 and 2, not shown) driven by eddycurrent drag from a rotating magnet (A), and wherein the blade S is thus snapped between two fixed contacts B and B<SP>1</SP> at two different vehicle speeds, is characterized in that the vehicle speed at which the snap action occurs in one direction is adjustable by adjustment of the position of one fixed contact. The adjustable contact is carried on, or moved by (Fig. 4, not shown), a spring-urged lever L which also acts as an armature of an electromagnet E the current through which is controlled, for example, by a rheostat or switch operated by the accelerator pedal. In the embodiment of Fig. 5 (not shown), a single speed-responsive member P is coupled to two such " S "" blade arrangements to provide two respective gear changes. If the accelerator pedal is depressed beyond its normal travel the adjustable contact may move the blade S over dead centre to effect a quicker change of gear. Instead of an electromagnet to control lever L a pneumatic, hydraulic, or simple mechanical linkage may be used.
