Title: Warhead and anti-tank missile construction - with parachute or flaps to provide braking effect and adjust projectile to vertical trajectory
IPC: F42B12/14
Filed: 1967-10-06
Granted: 1976-12-31
Abstract: The explosive charge forms a portion of the body of a missile. The missile includes a nose having a telescopic rod which is extendable and actuated upon impact to initiate explosion. Thus at least one of the charge liners is at a height which corresponds to the maximum height of the target. The missile body has flaps which may be moved outwardly, or a parachute which may be ejected, to provide a braking effect on the missile and cause it to adjust to a vertical direction. The missile may also include means for restabilising the missile after it has been adjusted to a vertical drop; for example tail fins or a parachute which is ejected from the nose of the missile and which effects the reversal thereof to a position in which the tail extends downwardly.

Title: Improvements in or relating to transistor modulator circuits
Inventor: STEWART ALAN
IPC: H03C1/36
Filed: 1968-01-09
Abstract: 1,204,215. Amplitude modulators; transistor amplifiers. MINISTER OF TECHNOLOGY. 7 Jan., 1969 [9 Jan., 1968], No. 1343/68. Headings H3R and H3T. A modulator comprises transistors Q1, Q2, Q3 of the same conductivity type, with the carrier applied to the base of Q3, and antiphase modulation signals applied to the bases of Q1, Q2, the carrier signal range embracing the ranges of the signals at the bases of Q1, Q2: When the instaneous voltage of the carrier signal at the base of Q3 is less than the instantaneous voltage of the modulation signal at the base of Q2, transistors Q1, Q2 act as emitter followers, transistor Q3 is cut-off, and the output signal at 17 follows the voltage at the base of Q2. When the instantaneous carrier voltage lies between the instantaneous voltages at the bases of Q1, Q2, Q1, Q3 act as emitter followers, Q2 is cutoff, and the output follows the voltage at the base of Q3. When the instanteous carrier voltage exceeds the instantaneous voltage at the base of Q1, Q1 cuts-off, and any further rise in output voltage is limited by the high source impedance of the carrier signal generator. Thus the output signal is a form of the carrier with its peaks clipped at the instantaneous levels of the modulation inputs at the bases of Q1, Q2, Figs. 2(a), 2(b), 2(c) (not shown). Two such modulators may be fed with antiphase inputs to give a suppressed carrier output. The modulation amplifier comprises a drift connected amplifier Q8, Q9, Q10 feeding to stages Q6, Q7 which produce the antiphase output signal superimposed on appropriate D.C. leads. The power supply to the circuit (not shown) comprises a series transistor with its base connected to two further transistor strapped as diodes. Q6, Q7 may be replaced by a single transistor with one output taken from the emitter circuit and one from the collector.

Title: Improvements in and relating to electrically heated melting pots for typographical casting machines
IPC: B41B11/76
Filed: 1938-01-18
Abstract: 509,767. Automatic control systems. LINOTYPE & MACHINERY, Ltd., SCOTT, R. H., and BROWN, W. Jan. 18, 1938, No. 1629. [Class 38 (iv)] [Also in Group XI] Temperature.-An electrically heated melting- pot is provided with a plurality of elements, switchgear to initially render active all said elements, and a thermostat which initially operates to render inactive a plurality of elements, and thereinafter controls a reduced number thereof. In the embodiment of the invention shown in Figs. 1 and 2, the pot has two separate elements 2 and 3, and a thermostat 4 which has normally closed contacts. The control mechanism consists of a double pole switch 7, with an additional contact 8, two electro-magnetic relays 9, 10, and an ammeter 11. When the main switch 7 is closed, the blade connects with the contact 8 and current passes through thermostat 4 and the coil of relay 10, thus closing contacts 12-13 and allowing the element 3 to remain energised when the switch is fully closed. The final closing causes the relay-coil 9 to be energised, and the contacts 14-15 close thereby energising the element 2. When the thermostat 4 opens the current flowing through the coils of relays 9 and 10 is reduced and the contacts thereof open rendering the elements 2 and 3 inactive. Upon a fall of temperature in the pot, the thermostat 4 closes and causes the relay-coil 9 and the element 2 to be energised, but the element 3 and the relay-coil 10 remain inactive until the main switch 7 is opened and again closed. The thermostat thus only controls one element after the initial heating stage the other remaining inactive. In a modification of the invention, the same results are obtained with a thermostat with normally open contacts.

Abstract: 1,157,093. Telephone answering machines. ANSAFONE Ltd. 30 Sept., 1966 [14 Jan., 1966], No. 1833/66. Heading H4K. A telephone answering and message recording device of the kind which reverts back to its standby condition in readiness to accept another call in response to the brief interruption in line voltage or current at the release of the connection by the calling party, replays the recorded messages in response to a code transmitted by an authorized caller. The code signal, which may be one or more tones generated by a whistle or electric portable generator, is transmitted and recorded after the caller receives the usual invitation to record a message, and upon being detected the device rewinds the recording tape and replays any previously recorded messages. The detection once again of the code signal recorded at the end of the messages may cause the device to replay the messages again or alternatively may switch the device back to a recording state to enable the caller to record his own message, but if he wishes to hear the messages again the code signal must be transmitted again. At any time the caller may hang-up to revert the device to a stand-by condition. If replay was in progress, however, the subsequently recorded message on the next call begins at the point on the recording tape where replay was terminated and in this way the authorized caller can remove some or all of the previously recorded messages by overrecording the ones yet to come. However, normally the caller hangs up at the end of the messages but before hearing the code signal.
