Title: Improvements in or relating to burglar alarms
IPC: G08B13/22
Filed: 1947-04-30
Abstract: 639,209. Burglar alarms. ASSOCIATED FIRE ALARMS, Ltd., and McNEIL, E. A. April 30, 1947, No. 11655. [Class 118 (i)] A burglar alarm of the type in which an electromagnet is normally maintained operated by current derived from the electric mains comprises means for maintaining the armature in the operated position should the mains supply fail. An operating electromagnet 2 is connected via burglar-operated contacts to the secondary of a mains transformer and is therefore normally energized. Operation of the burglar contacts disconnects current from the operating magnet 2, the armature 5 of which releases and at contact 6 closes an alarm circuit. The armature 5 is re-set by manual rotation of a spindle 9 and arm 8 which in turn rotates an arm 7 to lift the armature 5 into the field of the operating magnet, as shown. Restoration of the operating circuit will then cause the armature 5 to be attracted to its operated position, the arms 7 and 8 restoring to normal under the action of gravity and a spring respectively. An auxiliary magnet 10 is energized directly from the secondary of the mains transformer and is not released by operation of the burglar contacts. When, however, a power failure occurs, auxiliary magnet 10 as well as the operating magnet 2 releases and the auxiliary armature 15 latches a non-magnetic extension 16 of the operating armature 5 and retains the latter within the field of its magnet so that restoration of the power supply causes both armatures to be attracted. The system thus returns to normal and false operation of the alarm due to the restoration of power is prevented.

The strawberries are up-ended to bring the plug to the top of the cups by the operator's fingers or automatically by flotation in brine in the cups which are then made deeper and provided with leak channels. The cups are then automatically raised up to push the strawberries over the de-plugging blades 35, after which the cups 13 recede and a stop-plate 20 recedes down to pull the strawberry away from its plug. The plugs are released to drop into a reciprocated perforated tray 37-39 where they may be washed with a water spray 38 or collected for processing to recover some fruit. The cups 13 may be raised up from the bar 12 to meet the blades 35, by counterweights, not shown, adjustable to suit fruits of different softness. The cups 13 may then be locked by a hydraulic buffer in raised position to resist downward displacement by the push of the blades 35.

Abstract: 1,019,817. Pulse modulation circuits; transistor pulse oscillator circuits. AMPEX CORPORATION. March 24, 1964 [April 22, 1963], No. 12341/64. Headings H3T and H4L. In an oscillator for producing an output pulse train in which the pulse repetition frequency varies in accordance with the amplitude of an input signal, the input signal 70 is supplied to the base of a transistor Q2 and at time t 0  causes transistor Q3 to conduct and charge capacitor 54. At time t 1  the amplitude of the input signal rises to increase the charging current to the capacitor 54 and at time t 2  the input signal decreases and the charging current is reduced. The voltage across capacitor 54 is applied to an emitter of a cross-coupled  complementary pair Q4, Q5 and when this voltage is more positive than that at potentiometer tap 60 the transistors Q4, Q5 regeneratively become conductive to discharge capacitor 54 whereafter charging recommences. Thus between times t 0  and t 1  a high current will pass through transistor Q2 and a low current through Q3 so that capacitor 54 will charge at a slow rate and relatively few output pulses will be supplied to output 22, between times t 1  and t 2  the current through Q2 will be reduced and Q3 will pass a greater current and a greater number of pulses will be generated, and between times t 2  and t 3  the number of pulses will fall again.
