Patent GB-669624-A (GB)
Abstract: 669,624. Spring upholstery. NO-SAG SPRING CO. Aug. 9, 1950. No. 19792/50. Class 52 (iv). [Also in Groups XXV and XXXII] A clip for securing a spring 22, Fig. 4, to a frame element 17 has a loop portion 18 engaging the spring, an arched web portion 19 forming the closed end of the loop and the crest of the arch extending in a direction away from the open end of the loop. As shown in Fig. 4, the upper portion 18 of the clip is slotted at 29 (see also Figs. 6, 10) to provide spaced points which are operative to pierce a fabric 30 such as burlap which is used to cover the springs and is thus retained by the clip. The retaining members 27 mav be nails or screws. In the constructions shown in Figs. 6, 10, the clips are retained by a lug 33 which fits a hole 34 in the frame. The shape of the lug 33 may be complementary to that of the slot 29 in order to simplify stamping of the clips. The lower portion 16 may be continuous, and common to a spaced series of the upper portions 18. The clips may be of aluminium or brass. Specification 667,900, [Group XXV], is referred to.
Patent GB-783386-A (GB)
IPC: E05C19/18
Abstract: 783,386. Door locks. BEARDMORE, J. D. K. Nov. 15, 1955, No. 32678/55. Addition to 703,557. Class 44 A lock suitable for use with a pair of sliding doors of the kind in which the pair of doors are slidable in adjacent parallel planes to close off or to give access to the interior of a case or the like to which they are fitted, the closed position of doors corresponding to their positions of minimum overlap, comprises front and rear door stops 2a, 7 the latter of which is carried by an arm 6 and is movable by the locking mechanism, the lock being adapted to be positioned in relation to the pair of doors in their closed position with the front door stop 2a abutting the overlapping edge of the front door and the arm 6 with its rear door stop 7 passing between the overlapped portions of the doors and so that the rear door stop 7 is first movable into the path of opening movement of the rear door and the locking mechanism is then operable to lock the rear door stop in that position, the stops co-operating to oppose opening movement of the doors and prevent withdrawal of the lock. The lock is a modification of the one described in the parent Specification. As shown the lock comprises an outer casing 1 to one side edge of which a spring leaf clip 2 is secured for engaging one side edge of the front door. The base of this clip forms the front door stop 2a. Pivotally mounted in the outer casing 1 is a casing 3 which contains a key operable locking mechanism. The casing 3 is pivoted in the outer casing 1 by means of the arm 6 which carries the rear stop 7, the arm 6 passing through a boss 4 integral with the casing 3 and being clamped to it by means of a screw 5. When the casing 3 is swung away from the casing 1 the stop 7 is parallel with the surfaces of the doors and the doors can then be opened. When the casing 3 is swung into the casing 1 the stop 7 is moved to a position at right angles to the surfaces of the doors and prevents movement of them by engaging the rear door. In this position of the casing 3 operation of the locking mechanism causes a stop 8 to protrude through the casing 3 and to engage behind part of the front wall of the casing 1 to lock the casing 3 to the casing 1. The arm 6 can be adjusted for position within the boss 4 to bring the stop 7 into any desired position and the lock can be adapted for doors in which the right hand door overlaps the left hand door instead of vice versa as shown, by reversing the position of the step 7 in relation to the casing 1 and by removing the clip 2 from the left hand wall of the casing 1 and screwing it to the right hand wall. Both side walls of the casing 1 are provided with threaded holes to enable this to be done.

Title: Radio Receiver for Traffic Information Broadcasts
IPC: H04H20/00
Filed: 1978-10-05
Abstract: The receiver has an automatic scanner 2, a station signal decoder 6, a message signal decoder 7 and receiving level evaluator 10 as well as a control circuit 20 controlled by the said decoders and evaluator, the said control circuit interrupting the scanning operation and switching on the sound reproduction device 15 only when a traffic information broadcasting station which is worth receiving and which is transmitting traffic information is received. The control circuit 20 is constructed so that the number of traffic information broadcasting stations worth receiving is automatically limited depending upon their number and receiving level. For example the number of traffic information broadcasting stations received may be limited to a number e.g. two, 51, 52 of those received at the highest receiving level. <IMAGE>
Patent GB-2017445-A (GB)
Title: Digitally controlled signal simulator
IPC: G01S7/40
Filed: 1978-11-08
Abstract: A signal simulator for generating a simulated target signal useful in testing the receiver and data processing portions of radar systems is disclosed. Input signals to the signal simulator include a multi- pulsed synchronizing signal having substantially the same duty cycle and PRF (pulse repetition frequency) as the RF output signal of the radar transmitter normally used in conjunction with the receiver, digital signals specifying the acceleration, the initial velocity and the initial range of the target to be simulated. A target range calculator circuit utilizes the acceleration, initial velocity and initial range signals to calculate the range of a simulated target. A plurality of delay circuits are sequentially initialized by the synchronizing signal to generate a trigger signal delayed from the synchronizing signal with the delay corresponding to the range of the simulated target. The pulse width of each pulse of the synchronizing signal is measured and stored. A pulse generator circuit in response to the trigger signal reads the stored values corresponding to the width of the pulses of the synchronizing signal and generates a delayed synchronizing signal having the same PRF and duty cycle as the synchronizing signal with the delay corresponding to the range of the simulated target. The target range calculator also generates a signal which determines the amplitude and a signal which determines the frequency of the simulated target signal. These signals are coupled as input signals to a signal synthesizer. The output signal of the synthesizer and the delayed synchronizing signal are coupled to a signal generator to generate the simulated target signal.

Patent GB-2106354-A (GB)
Title: Alarm monitor
Inventor: FORD ALISTAIR DAVID JAMES
IPC: H04M11/04
Filed: 1981-09-08
Abstract: A fault reporting system, in the example described for use in a and telephone system, reports the faults by speech derived from a speech synthesizer (4). The alarm inputs are monitored by an alarm detection unit (2), and when this finds an alarm to be reported it operates an auto-dialler (5) via a control unit (3), as a result of which a remote alarm centre is called. While this is in progress the alarm detection unit (2) and the control unit (3) cause a message for reporting the fault to be generated and passed to the speech synthesizer (4). When the alarm centre replies, this is detected by an answering unit (6), which via the control unit (3) causes the message to be speech synthesized and the result sent to the alarm centre for recording thereat. The basic idea is applicable to other forms of alarm and event recording. <IMAGE>
