Title: Improvements in or relating to time-keeping apparatus
IPC: G04C3/027
Filed: 1958-11-06
Abstract: 901,810. Electric clocks and watches. JAHRESUHREN-FABRIK G.m.b.H., AUG, SCHATZ & SOHNE. Nov. 6, 1958 [Jan. 10, 1958], No. 35735/58. Class 139. A timepiece comprises an electronic oscillator which either maintains a mechanical oscillator or directly drives the counting train. When the electronic oscillator maintains the mechanical oscillator it may comprise two coils 2, 3, Fig. 1, normally decoupled by a metal screening but instantaneously coupled by a permanent magnet 5 carried by the mechanical oscillator and the resulting train of unipolar pulses maintain the mechanical oscillation. The coils may be located side by side, one behind the other, or one telescoped in the other and they may be situated in the base of the timepiece out of sight. Several permanent magnets may be used and regulation may be effected by adjusting the space between the coil 2 and the permanent magnet or magnets. The electronic oscillator may be of any kind and may include a diode to ensure complete decoupling of the circuit components. The frequency of the oscillator may be stabilized by a quartz crystal. In another example, Fig. 4, an auxiliary winding 10 is provided to give a tighter coupling. When the electronic oscillator directly drives the counting train it acts through a permanent magnet and a small adjustable armature tipped with a non-magnetic material attracts the permanent magnet to a rest position.

A radiator valve comprises a closure disc 22 co-operating with a valve seat 4 and carried by a rod 24 which is threaded into a sleeve 23. A chamber 13, one wall of which is a bellows 12 against which the sleeve abuts, is filled with liquid, the temperature of which determines the position of the valve. The chamber 13 is threaded into a part 7 attached to the valve body and is fixed to a knob 9 formed with an indicator. Rotation of the knob and with it the sleeve 23 and rod 24 varies the temperature at which the valve closes.

Title: Improvements in and relating to electric motors
IPC: H02K25/00
Filed: 1929-11-29
Abstract: 344,046. Centrifugal governors. ELLIS, R. E., 70, Chancery Lane, London.- (Adams Sibley Development Corporation ; 142, West 80th Street, New York, U.S.A.) Nov. 29, 1929, No. 36692. [Class 57.] The speed of an electric motor suitable for gramophone-driving or other small loads is governed centrifugally by a device which at a limiting speed suspends the establishment of magnetizing currents in the rotor by withdrawing the rotary spring- mounted brush of a contact maker from the fixed contacts with which it normally co-operates. The motor comprises bar magnets 16, Fig. 1, a rotor with stellate laminated pole wheels 19, 20 at its ends and a coil 35 between them. A disc 21 insulated from and rotating with the shaft carries a brush which makes and breaks contact successively with a series of contact blocks in order to establish unidirectional current pulses in the coil 35 and so give magnetic attractions between the rotor poles 19<1>, 201, and the magnets 16. The brush 28, Figs. 2 and 6, is mounted on a V-shaped spring 27 attached to the limbs of a U-shaped spring 23 which is secured at 24 to the disc 21 and provided with centrifugal weights 26. The brush makes successive contact with tongues 30, Fig. 3, extending from a common plate 32 through openings in a fixed insulating disc 29 in the casing cover 31. The plate 32 is connected to one battery pole and the circuit is completed as shown in Fig. 6, through a tongue 30, brush 28, spring 27, governor spring 23, disc 21, coil 35, rotor core and machine casing 15. At a limiting speed, the action of the weights 26 flattens the spring 20 and, by withdrawing the brush 28 from the tongues 30, suspends the current impulses in the rotor until the machine has slowed down. The speed of the machine is controlled by raising the rotor spindle bodily in its bearings together with the disc 21, governor 23, and brush 28. This is done by means of rod 39, Fig. 2, screwed in the casing and bearing at its lower end on the inclined end 40, Fig. 3, of a sliding rod 41, the other inclined end 42 of which supports the lower end of the rotor spindle on a ball.

Title: Glass molding process and apparatus
IPC: C03B19/06
Filed: 1962-09-27
Abstract: <PICT:0962297/C1/1> In the moulding of glass, glass in solid form, positioned in a closed expansible mould cavity which has been evacuated, is heated until plastic, pressed until it fills the cavity and cooled to separate the glass from the mould.  The apparatus comprises a chamber 12 of quartz or like material sealed at each end by metal plates 14, 16, the plate 14 having a fitting 22 for connection to a vacuum pump and the lower plate 16 incorporates a thermocouple 64, with ends 66, 68 extending through glass headers 70, 72. The mould 24 comprises metal bottom part 34, ring 36 and tubular upper part 38 with central bore 40 with flared lower end to give mould cavity 42.  The mould 24 is supported on a metal plate 26 and is clamped within a metal tube 32 by clamps 44, 46, the plate 26 resting on a heat insulating block 28 through which the thermocouple 64 extends.  Glass rod 52 or powdered material is inserted in mould cavity 42 with metal insert 54 and a plunger 56 rests on the glass rod 52, sliding in bore 40 and pressed down by a weight 58.  The chamber 12 is evacuated and the glass 52 is then heated by an induction heating coil 60 surrounding the chamber 12 to cause the glass to flow to fill the cavity 42.  The metal of the mould 24 has a coefficient of expansion lower than that of the glass so that the glass on cooling will automatically separate from the mould.  To prevent sticking, the metal parts are lubricated by water-carbon suspension.  Instead of evacuating the chamber 12, it may be filled with inert gas such as helium or argon.

Title: Fluid pressure operated apparatus to position an actuator rod
IPC: F02K1/15
Filed: 1956-11-30
Abstract: 850,374. Fluid-pressure servomotor-control systems. GARRETT CORPORATION. Nov. 30, 1956 [Dec. 2, 1955], No. 36771/56. Class 135. A fluid-pressure operated apparatus to position an actuator rod 43 comprises a pressure regulator 12 delivering regulated pressure fluid at a pressure exceeding ambient by a constant amount to a chamber 25 formed by spring- biased diaphragms 23, 24 in an actuator 10. Regulated pressure fluid exhausts from the chamber 25 to atmosphere through a pair of orifices 30, 31 at sonic speeds and the pressure between the orifices, which is a constant fraction of the regulated pressure, is fed to a chamber 27 in the actuator through an orifice 32, so that the pressure differential acting on the diaphragm 24 actuates a pilot valve 38 co-operating with a moving seat 41 formed in the actuator rod 43 which is connected to the diaphragm 23. Regulated pressure fluid is also bled through a restriction 28 in the diaphragm 23 to a chamber 26 from which it exhausts to atmosphere through passages 42, 44 in the actuator rod under the control of the pilot valve. Thus, if the apparatus is installed in an aircraft to vary the area of a propelling nozzle, on the aircraft gaining height, the pressure differential across the diaphragm 24 decreases and it is moved to the left of the Figure under its spring load to open the pilot valve, which relieves the pressure in the chamber 26, and diaphragm 23 moves to the left under the applied pressure differential to move the actuator rod 43 and vary the area of the propelling nozzle and to cause the seat 41 to follow up the pilot valve until steady conditions are reached. The pressure regulator 12 comprises a diaphragm 15, one side of which is biased by a spring 14 having an adjusting screw 18 and communicates via an opening 13 with atmospheric pressure, and the other side of which abuts a spring-loaded valve element 16 that regulates the pressure of fluid supplied from a pressure fluid source through an opening 17 in the regulator casing to the pneumatic actuator and is acted upon by fluid at the regulated pressure through an orifice 20. The initial position of the actuator rod is determined by adjusting the tension of the spring acting on diaphragm 24 and the aperture of the nozzle 31, and its travel is limited by adjustable stops 49.
