Abstract: 1,169,180. Breaking. VICKERS Ltd. 16 Feb., 1967 [19 Nov., 1965], No. 49237/65. Heading B3E. A process for parting a normally ductile metallic member into sections comprises inducing a brittle fracture in the member by raising the yield stress above the cleavage stress as a result of introducing a zone of increased stress in the member at the, or each, intended point of fracture and subjecting the material of the member at this point to a high strain rate by means of a high velocity impact. A bar notched at 12 by means 11 is clamped by means 13 and hit by a striker 14. The notch may be machined, pressed or rolled. The striker may be propelled pneumatically, hydraulically, mechanically or electrically, e.g. by a linear induction motor. The bar may be cooled. A notched bar may be supported at spaced points on opposite sides of the notch and hit in the notch by a striker, Fig. 2a (not shown). The apparatus, Fig. 3, may incorporate a double acting pneumatic cylinder 17 with a striker 18 at each end engaging, alternately a bar 10, notched and fed forward by means 19 and clamped by means 20, and a bar 10<SP>1</SP> notched, fed and clamped by similar means 19<SP>1</SP>, 20<SP>1</SP>.

Title: System for indicating synchronisation of alternating current signals
IPC: G01R29/18
Filed: 1973-10-26
Abstract: 1439070 Synchronizing A.C. sources GENERAL ELECTRIC CO 26 Oct 1973 [30 Oct 1972] 50028/73 Heading H2H A system for indicating when a first A.C. source 12 is synchronized with a second A.C. source 14 comprises a frequency discriminator 18, a phase angle discriminator 20 and a frequency difference circuit 26. The source 14, which is to be connected into an operating power line when the sources are synchronized, may be a gas turbine generator. The system provides a synchronization signal to enable the connection of the generator to the operating power line only when three conditions are satisfied. The conditions are finally that the frequency of the generator signal must exceed the frequency of the operating power line signal, secondly that the phase angle between the signals must not exceed 20 degrees and thirdly that the difference in the frequencies of the two signals at the instant of connection must not exceed À33 Hz. If the first condition is not satisfied, the frequency discriminator 18, which receives square wave signals from the sources 12, 14 via an amplitude discriminator 16, supplies a signal via gates 21, 42 to cause an increase in the generator speed. When the increased frequency of the generator 14 exceeds the frequency of the source 12 the frequency discriminator 18 supplies a signal to an "AND" gate 22. To ensure that the second condition is satisfied, the phase angle discriminator 20 includes a monostable multivibrator (90), Fig. 6 (not shown), which generates a pulse having a width equal to a phase angle of 20 degrees at the frequency of the source 12. Provided the phase angle between the signals from the sources 12, 14 is less than 20 degrees, the discriminator 20 supplies a second input to the "AND" gate 22. To ensure that the third condition is satisfied, the frequency difference circuit 26 includes 2 second and 4 second time delay circuits (106, 108), Fig. 8 (not shown) which enable a signal to be provided on a "LO", "OK" or "HI" output depending on whether the frequency difference is less than À2 Hz, lies between À2 Hz and À33 Hz or is greater than À33 Hz respectively. Either of the first two outputs supply the third input to the "AND" gate 22 via an "OR" gate 34 thereby enabling the system to supply a signal which indicates synchronism of the two sources. A signal on the "HI" output enables an "AND" gate 24 to supply a signal for decreasing the speed of the generator.

Abstract: 1,026,419. Hydraulic rams. ENGLISH DRILLING EQUIPMENT CO. Ltd. Dec. 14, 1964 [Dec. 19, 1963], No. 50131/63. Heading F1P.  The wall of the intermediate cylinder 21 of an hydraulic telescopic ram, Fig. 2 (not shown), has an aperture 23 which when uncovered by the piston 22 during the start of the extension stroke as shown in Fig. 4 (not shown), allows transfer of fluid trapped in the annular space 35 between said cylinder 21 and an outer cylinder 20 to the pressure side of the piston 22 to which fluid is supplied through a bore 26 in the outer cylinder head 25. A reduced diameter portion 34 of the piston rod 33 is slidable through a load plate 36 and is of slightly less length than that of the piston 22 whereby the load plate begins to be displaced by the piston as the aperture 23 is opened after which the piston 22 and cylinder 21 move together until shoulder 30 of cylinder 21 abuts a shoulder 27 of cylinder 20 after which piston 22 is further extended to the position shown in Fig. 5 (not shown). The thrust available during the two stages is said to be constant and dependent on the effective area of piston 22 since during the first stage the thrust exerted by the intermediate cylinder is largely used in transferring fluid from space 35 through aperture 23.

Abstract: 1,123,291. Amplifiers; switching circuits. AMERICAN DISTRICT TELEGRAPH CO. 16 Dec., 1965 [19 July, 1965], No. 53526/65. Heading H3T. [Also in Division G4] An arrangement for detecting movement in an area to be protected comprises a light source energized from an A.C. supply which illuminates a photo-electric detector, the intensity of illumination being modulated by any movement in the area. The detector provides an amplitude modulated output signal which is demodulated and fed to a unit which initiates an alarm in response to a predetermined variation in the demodulated signal. The output from the photo-electric detector unit 106 is fed to an amplifier 109 Fig. 3 tuned to the carrier frequency by a twin-T feedback network, and also provided with a second feedback path RX6, RX7, RX9, CD5 to give a low frequency cut-off. The amplifier output is demodulated by diodes REC3, REC4 and fed to amplifier 114. Any decrease in modulation signal results in an increase in signal at the base of transistor TS6, Fig. 4 and relay AL energizes. Any increase in modulation causes capacitor CP15 to discharge through transistor TS5, and the subsequent recharging again increases the signal at the base of TS6. Should an extra strong, unmodulated, carrier be received due to tampering with the system, the zener voltage of diode REC5 is exceeded and transistor TS5<SP>1</SP> becomes conductive, again energizing relay AL. Actuation of relay AL changes contact AL1 to complete a circuit to horn H1, and to open the circuit of relay S, completing the circuit to horn H2 via contact S1. Power failure results in S1 releasing to actuate H2 only. Contacts AL2 S2 are provided to signal to a remote station, in which case the local alarms may be silenced by the removal of jumpers 132, 133, 135. In order to test the system, switches SW3, SW4 are set to their opposite position disconnecting the horns and replacing them by lamp LP3. A number of detectors 106, 106<SP>1</SP> may be connected in cascade to the amplifier, or alternatively, Fig. 5, 6 (not shown) the detectors may be associated with individual pro-amplifiers and attenuators and may be connected in parallel to the amplifier. Each detector unit comprises a number of cells operating in the infra-red region arranged around the image plane of a lens, Fig. 2 (not shown). The movement detected may be that of an intruder, smoke, or flame flicker.
