Title: Improvements in and relating to frequency sensitive electro-mechanical apparatus
IPC: H03H9/46
Filed: 1954-05-28
Abstract: 788,159. Electro-mechanical filters &c. PHILCO CORPORATION. May 28, 1954 [May 29, 1953], No. 15850/54. Class 40 (8). [Also in Groups XXXVI and XL (c)J An electro-mechanical device, e.g. a frequency filter, comprises an electrostrictive element, of e.g. Rochelle salt or polarized barium titanate, secured to a vibratory reed. The reed 10, Fig. 2, which may be made of metal or of glass, is secured to the electrostrictive element 14 by means of a thermosetting bonding material. The element is provided with platinum input or output electrodes on its upper and lower surfaces and is polarized along an axis joining these two surfaces. It is secured to a massive base 20 and overhangs this base by a substantial amount in order to allow flexural vibration of the assembly in a vertical plane. The neutral axis of the longitudinal compressive and tensile stresses associated with this vibration is arranged to coincide with the upper face of the element. An input signal may be applied by means of an electromagnet 22 and the output detected by means of a detector 26. Alternatively, the input may be applied by means of a second electrostrictive element secured to the reed 10 opposite the first element 14 (Fig. 4, not shown). Two such assemblies comprising reeds 60, 62, Fig. 5, and elements 66, 68, 70, 72 may be mechanically coupled by a block 74 and mounted on a common base 76. The mechanical coupling 74 causes the reeds 60, 62 to vibrate 180 degrees out of phase, thus minimizing the coupling to the base 76. The pairs of elements 68, 70 and 66, 72 are polarized so that like charges appear on their exposed surfaces, the input and output connections being made as shown. Alternatively, the polarization and connections may be arranged so that one adjacent pair, e.g. 66, 68, of elements serves as the input and the other, e.g. 70, 72, as output. The mechanical coupling block 74 may be secured directly to or formed integrally with the reeds 60, 62 in which case the inner elements 68, 70 may be positioned above the block. One pair of elements, e.g. 66, 68 may be omitted to produce an asymmetric system. Several such pairs of reeds tuned to the same or to slightly different resonant frequencies and having, if desired, different bandwidths may be combined in a single assembly (Fig. 6, not shown). Such a system may be connected up to provide frequency characteristics, e.g. of the band-pass type, Fig. 7A, or of the type shown in Fig. 7B.

Abstract: 636,224. Starting prime movers. SCINTILLA AKT.-GES. June 20, 1947, No. 16393. Convention date, June 22, 1946. [Class 38 (iv)] [Also in Groups XXVII and XXXVII] An electric starter for internal-combustion engines (see Group XXVII) is operated by closure of a switch 58 which causes the contact 23 of an electromagnetic switch 22 to start closing; the full travel of the contact is prevented by a mechanical latch. The initial travel of contract 23 is sufficient to withdraw a stop and allow spring contacts 50, 51 to complete a circuit through a highly-rated field winding 5 and so turn the starter slowly backwards to engage the starter pinion with a gear of the engine to be started. When the starter is fully in mesh, the latch is tripped and the contact 23 closes and in so doing closes spring contacts 51, 52. Closure of contact 23 completes the circuit through the main field winding 4, whilst closure of spring contacts 51, 52 reverses the current in the field winding 5 and at the same time connects it in series with an auxiliary winding 6, under which conditions the starter rotates forwardly and cranks the engine, since windings 5, 6 assist the main field winding 4.

Abstract: 1,085,284. Fluid-pressure brakes. FORD MOTOR CO. Ltd. April 15, 1966, No. 16537/66. Heading F2F. A vacuum servo unit 6 for a master cylinder 3 of an hydraulic brake system is arranged with its axis transverse to that of the master cylinder and has a combined control and output member 8 which is coupled to two links 5, 12, arranged between the master cylinder piston 2 and brake pedal 1, through a bell crank 7 which is pivoted at 9 to a support 10 for the servo unit, and has its arms 7a, 7b connected respectively to the member 8 and a pivot 11 interconnecting the two links 5, 12. When the pedal is depressed, the initial movement of link 12 merely compresses a rubber reaction pad 14, but the resulting movement of the member 8 is sufficient to operate a valve spool (22, Figs. 2- 4, not shown) which slides within the power piston (15) of the servo unit 6, causing the rear chamber (19) to be cut off from the evacuated front chamber (18) through closure of a valve passage (21) by a spring-loaded valve piston (24), and atmospheric air to be admitted to the rear chamber (19) by subsequent separation of the valve spool from the valve piston, whereby a pressure differential is created across the piston (15) and an associated diaphragm (17) to apply a boosting force to the member 8, and thence to the link 12, to supplement the pedal effort and effect movement of master cylinder piston 2. Since the valve spool (22) follows up this movement, equilibrium is reached when the pressure differential across the diaphragm of the servo unit corresponds to the pedal pressure. A spring (20) within the front chamber (18) of the servo unit effects return of the linkage as pressure on the pedal, and hence the pressure differential across the diaphragm, is reduced.

Abstract: 110,638. Vickers, Ltd., and North, T. K. Nov. 22, 1916. Mines, marine. - Relates to mines provided with arm s adapted to extend out and, if struck by a passing ship, to release the firing-mechanism, and consists in unlocking these arms, to allow them to extend out, by a pull exerted on a locking-device by a connexion with the anchor when this separates from the mine during the laying operation. In the form shown, each arm comprises a sliding tube d normally telescoped into a fixed tube d' against a spring d<2>, and held in place by a transverse split pin c<1>. The pin is connected to the anchor by a cord c<7>, and is locked by a wedge c' connected to a handle c‹ by a cord c<5>. The wedge c<4> is removed before the mine is laid; and, during laying, the cord c' pulls out the split pin, and the tube d is moved by its spring to project beyond the surface of the mine, and is locked in the extended position by a spring stud d<3>, which also prevents rotation of the tube d during the sliding movement by engaging with a groove d<4>. The firing-mechanism is that described in Specification 15707/15. When an arm d is struck by a ship, a pin g<2> screwed to the base of the tube d<1> is broken. This releases a bent lever g<1>, allowing a cord G<2> to be pulled by a spring G<1> and thereby to rotate a pulley g<3>, which releases a bayonet joint connexion, and allows the firing pin H to be cocked by the pull of the moving cable C and then to be released by radial bolts to fire the mine.
