Title: Burglar alarm
IPC: G01S13/56
Filed: 1976-04-05
Abstract: 1481884 Burglar alarms BERNA INDUSTRIES Ltd 5 April 1976 [9 April 1975] 14621/75 Heading G4N A burglar alarm which produces an audible alarm when the presence of a burglar is detected by disturbance of a microwave field includes a timer 25 for terminating the audible alarm after a predetermined interval and carrying a visual indicator to be operated at the end of this interval. As shown, the alarm consists of a microwave doppler module 20 whose output signal is processed at 21. Upon detection of a burglar, the processor 21 cause a latch circuit 18 to be set which in turn causes an audible alarm to be given by a buffer 23, an audio generator 22 and a power amplifier and speaker 24. The latch 18 also causes the timer 25 to be set, and after the predetermined interval the timer 25 causes the latch circuit 18 and itself to be reset and also sets a latch circuit 19 which then operates a red l.e.d. driver 28 to give the visual indication. The alarm also comprises a key operated switch consisting of normally open switches 10 and 11 and normally closed switch 12. Upon setting of the alarm, the switches 10, 11 and 12 assume their opposite positions and the circuitry is powered by the means via a power supply 14. A battery 13 is simultaneously charged. Should the mains supply fail, a green l.e.d. driver 16 is de-energized the circuitry is automatically powered by the battery 13. A timer 17 inhibits the latches 18 and 19 for a predetermined period after the alarm is set, thus allowing the operator to leave the premises without setting off the alarm. The output from latch 18 may also activate a transmitter in communication with a receiver at a remote station. The receiver can thus set off additional audible alarms or automatic telephone dialling apparatus. The communication link between transmitter and receiver may be by injection of coded r.f. signals into the mains circuit.

Title: Folding box
IPC: B65D85/32
Filed: 1936-05-23
Abstract: 469,629. Folding boxes. FAIRWEATHER, H. G. C. (Cormier, A., and Cormier, C.) May 23, 1936, No. 14649. [Class 18] A paperboard &c. box for eggs, fruit, &c. adapted to prevent unauthorized substitution of contents is made, e.g. from a blank of the form shown in Fig. 1, folded into two or more troughs with partitions of the form shown in Fig. 8, inserted into slots 11, 12, 13. In assembling, the blank is folded downwardly about a folding line 15 and upwardly about folding lines 16, 17 to bring slots 11, 12 13 into alignment, the partitions 27, Fig. 8, being then inserted. The side wings of the blanks are then moved so that folding takes place along lines 18, 20 instead of 16, 17 so that a slot 34 in partition 27 comes beneath lugs 14 in slots 11 and a slot 33 engages the ends of slots 11, the partitions being thus locked against withdrawal. For packing, the partitions are turned to lie flat against the centre longitudinal partition and the blank folded about lines 23, 24 to the configuration shown in Fig. 5, rubber bands or gummed paper strips between the outer ends of the body member being used to retain the box in folded condition. The box is expanded by pulling the side wings of the blank. By suitably arranging the width of slots 34, 33 the folded box is given a tendency to expand resiliently into set-up position. The parts of the partitions engaging the slots may be slightly larger or slightly smaller than the slots. The partitions cannot be removed from the box when in extended position, without tearing them. The blanks and partitions may be made in one operation by machine and may be assembled by machine.

Abstract: 475,427. Inductances. AKT.-GES. BROWN, BOVERI, & CIE. May 25, 1936, No. 14700. Convention date. June 5. 1935. Addition to 467,574, [Group XXXVI]. [Class 38 (ii)] [Also in Group XXXVI] The coils of the band resistance according to the parent Specification are provided with one or more iron cores for the purpose of damping any current surges which may arise more particularly when the resistance is used in circuits for welding. Two spiral band resistance coils a connected in parallel are provided with two laminated iron cores consisting of yoke pieces v and limbs w, one of each of which is embraced by the coils a. The middle limbs are slotted at y for enabling the current collector carried by the rotary arm z to be displaced by rotating the shaft x. The current collector and the parts x, z are connected to the iron cores, so that the width of the slot y may be reduced to a minimum and no insulation between those parts is necessary. The resistance coil may be formed by winding the resistance band and a somewhat narrower heat resisting insulating band together to form a spiral, the latter band assisting to dissipate heat from the resistance band. A number of resistance units and iron cores may be mounted in a casing 1 of perforated metal provided with a protecting cover 3, the resistance band being maintained rigid by bolts which are fixed to supporting members attached to the iron cores.

In the form shown in the Figure two chambers 1a, 1b have the first orifices connected in series to the pipe 6 and a second orifice 3b is to be compared with a standard variable orifice 3a the size of which can be adjusted-by hand or automatically by moving a conical needle valve 50 in and out of the orifice. When the heights of liquid in the limbs of the manometer move one way or other from a datum level the circuit of a motor 45 is completed and this operates the needle 50 through gear 46, 47 and a screw to restore the level in the manometer. A worm 51 turns a graduated disc past a pointer 53 to indicate the movement of the needle valve 50. A hinged strip or rotating wedge may be substituted for the needle to vary the orifice.

Filed: 1968-03-29
Abstract: 1,179,223. Hydrostatic steering mechanism. INTERNATIONAL HARVESTER CO. 29 March, 1968 [31 March, 1967], No. 15130/68. Heading B7H. In power-assisted steering mechanism comprising an hydraulic steering motor 18, an hydraulic supply pump 12, and a rotary control valve 67 and control pump actuated by a steering wheel 20, a valve assembly 68a normally operative to isolate the steering motor 18 from the remainder of the system responds to fluid flow from the control valve 67 to direct such flow to one end of the motor and simultaneously allow release of fluid from the other. The valve assembly 68a comprises a shuttle element 69 mounted for reciprocation in a bore 68, and a pair of spring-loaded poppet valves 88, 89 which normally close apertures 71, 79 between parts 92, 93 for the motor conduits 16, 17 and chambers 96, 97 at the ends of the shuttle element 69. Grooves 94, 95 opening into the chambers 96, 97 are connected by respective passages 98 (not shown) and 99 to passages 63 (not shown) and 64 extending from the control valve 67 to the control pump. When the steering wheel 20 is rotated the control pump discharges into one of the passages 63, 64 and a resultant pressure increase in the associated chamber 96, 97 opens the adjacent poppet valve 88, 89 to permit flow to the motor 18, and moves the shuttle valve 69 to a position wherein one of projections 77, 78 thereon opens the other poppet valve so that fluid can flow from the ram through passages 72, 74 or 73, 75 in the shuttle valve 69 to an outlet port 66 connected to a reservoir 10. Actuation of the control valve 67 by the rotation of the steering wheel 20 directs pressure fluid supplied from the pump 12 at an inlet port 65 into the other of the passages 63, 64 and thence to the inlet side of the control pump to provide power assistance. The control valve 67 comprises an inner element 54 integral with the steering shaft 22, and a sleeve 33 connected to the inner element 54 with provision for limited relative rotation by leaf springs 44. Co-operating longitudinal slots in the inner element 54 and sleeve 33 may be such as to provide either " closed centre " or " open centre " operation. The control pump comprises a fixed internallytoothed outer element 23, an externally-toothed eccentric inner element 24 driven by a shaft 29 engaging slots 34 in the end of the valve sleeve 33, and a rotary valve driven by a pin 36 engaging one of the slots 34. Ball valves 100 (not shown) and 101 permit the control pump to draw fluid from the reservoir 10 when the servopump 12 is inoperative so that steering may be effected manually.
