Title: Improvements in or relating to electric water heaters
IPC: H01H35/24
Filed: 1960-11-25
Abstract: 991,409. Fluid actuation of switches. L. H. VICKERS. Sept. 29, 1961 [Nov. 25, 1960], No. 40678/60. Heading H2B. In an electric water heater of the kind having a substantially flat base in which a water passage is formed and the base comprises a backplate 21 with water passage grooves 24, 27, and an ungrooved front plate 23 secured thereto with ports (not shown) registering with inlet and outlet positions 26, 28, of a heating element cartridge unit (Fig. 1, not shown) having a connected water passage therethrough, a pressure-sensitive element such as a piston disc or diaphragm 47 is arranged in a bore 44 of the plate 23 with the diaphragm 47 connected to a rod 39 extending outwardly through a gland in a plate 46 covering the bore, the rod and operating a microswitch 35 connected in series with the heating element. Connections leading from two spaced points in the water passage enter bore 44 on opposite sides of the pressure-sensitive element. Water flows through the water passage via inlet port 25, groove 24, the heating element cartridge unit, and groove 27 to an outlet 29. In the bottom of bore 44 is a port 45 registering with groove 27, downstream from the heating unit, while the upper surface of diaphragm 47 in bore 44 is exposed to the water pressure in groove 24, upstream of the heating unit, by means of a port 49 in plate 23 which puts groove 24 in communication with a tube 50<SP>1</SP> in a passage 50 in the cover plate 46. As the rate of flow of water increases, the increase in pressure difference across diaphragm 47 pulls the rod 39 down against spring 43 to operate switch 35 by a pivoted bell-crank lever 36, having one arm pressing against the switch plunger and the other longer arm connected to rod 39. An indicator light indicates current flow through the heating element or elements. Specifications 991,408 and 991,410 are referred to.
Patent GB-890842-A (GB)
Title: Improvements in or relating to bistable electrical circuits
IPC: H03K3/012
Filed: 1960-12-17
Abstract: 890,842. Transistor bi-stable circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 17, 1958 [Dec. 23, 1957], No. 40742/58. Class 40(6). A bi-stable circuit comprises two crosscoupled active elements and an input terminal for control pulses, a capacitor connected between the terminal and the input of each element and an inductor connected between the output of each element and its input, the circuit being such that successive input pulses of the same polarity change the state of the circuit, each inductor together with its associated capacitor forming a high pass filter for input pulses appearing at the input terminal and a low pass filter for output pulses appearing at the output of the elements. The Figure shows a bi-stable circuit comprising two transistors 27, 29 cross coupled through zener diodes 25 and 26 and having a constant current emitter supply 30, 28. Parallel normally non-conducting "pullover" transistors 10 and 11 are provided and the bases of these transistors are coupled to output circuit points B and C through inductive circuits 5, and 3, respectively and through capacitors 2 and 4 to a source of positive switching pulses 1. The leading edge of each pulse causes the bases of both input switching transistors 10 and 11 to go positive but this does not affect the condition of the circuit. The trailing, negative going edge causes both bases to be driven negatively. Assuming transistor 27 to be conducting, the base of transistor 11 is biased through inductor 3 to a positive potential whereas the base of transistor 10 is substantially at earth potential. Accordingly the negative going edge renders only transistor 10 conducting so that substantially the whole of the current from the constant current source 30, 28 is diverted to transistor 10 rendering transistor 27 non-conducting. The potential at point G in its collector circuit rises in a negative direction causing transistor 29 to become highly conducting and to carry the current previously passing in transistor 10 and so a change of the state of the circuit is effected. The trailing edge of the next positive pulse at input terminal 1 will render transistor 11 conducting so causing the circuit to revert to its initial condition. The inductance capacitance circuits 2, 3 and 4, 5 act as low pass filters for the input pulse enabling the pulses to be effective at points E and D but as high pass filters for the output pulses preventing the pulses at C and B from being transferred backwards through the network. Diodes 31 and 32 may be connected in the circuit to dissipate energy stored in capacitances 2 and 4 and so improve the switching time of the circuit and the zener diodes 25, 26 render the output voltage levels from terminals 35 and 36 suitable for use with other logical stages.

Filed: 1963-10-21
Abstract: 980,164. Electric cables. SUPERIOR CABLE CORPORATION. Oct. 21, 1963 [April 2, 1963], No. 41424/63. Heading H1A. The core of an electric cable is provided with a protective barrier formed from a corrugated tape of dielectric plastic material which may be wound helically as shown in the Figure, or applied longitudinally to the cable with its edges overlapping. The corrugations may be V-shaped, semicircular, sinusoidal, trapezoidal or square in crosssection or combinations of these. The ratio of the effective thickness of the tape to that of the normal flat tape may be 6 to 1. The Figure shows a corrugated metallic sheath surrounding the barrier with a final insulating jacket which is usually applied molten. Polyethylene terephthalate or a polyester film is suggested for the barrier material. The air spaces which the tape provides act to reduce heat transfer during the jacketing operation, to reduce the dielectric constant and increase the dielectric strength of the jacket, and to protect the cores from crushing by irregularities in the metallic shield during its application.

Title: Electrical filters
IPC: H01P1/201
Filed: 1972-09-13
Abstract: 1444540 Filters PLESSEY CO Ltd 28 Aug 1973 [13 Sept 1972] 42414/72 Heading H1W Filters are formed by connecting shortcircuited stubs in pairs to spaced common points on a main transmission line. Each pair of stubs forms a complete loop which is shortcircuited at an intermediate point. The connection points are spaced apart by an odd number of quarter-wavelengths at the centre frequency of the filter and the aggregate length of the stubs forming each pair is equal to a multiple of one wavelength at this frequency. Each stub, however, varies from a half-wavelength (or appropriate multiple) by a small amount which determines the band-width of the filter. Thus a filter consists of successive pair of stubs of lengths # 0 /2 Œ# r  where r is different for each pair and runs through 1 to n where n is order of the filter. In the 2nd order filter of Fig. 3, the pairs of stubs 1, 2 and 3, 4 (shown as single lines) are each constituted by a loop having a short-circuit realized in the form of a slider which is common to both loops. As shown in Fig. 4a, a rotary slider 15 adjustably connects tracks 10, 11 to a conductive disc 14 to which the earth conductors of all the stubs are connected in common. The "live" conductors of lines 1, 2 are connected respectively to terminals 12 and those of lines 3, 4 to terminals 13. The loops shown in Fig. B are thus completed by the tracks 10, 11. Where there are more than two pairs of stubs, a slider using a number of concentric tracks may be used.

Abstract: 1,160,528. Gyroscopic apparatus. BELL & HOWELL CO. Sept.28, 1966 [Sept.29, 1965(2)], No.43347/66. Heading G1C. [Also in Division G2] A gyroscope rotor 2, which may be used for stabilizing a lens of a camera by means of suitable linkwork or a selsyn system, is driven by a shaft 6 having a spherical ball 4 at its end, the ball having a circle of contact 54 with a plastics sleeve member 46 held in a hollow extension arm 10 of the rotor 2, the ball 4 being held in frictional contact with the circle 54 by a spring 62 acting on a plastics plug 56 which makes point contact with the ball 4. The rotor 2 spins in bearings 30, 31 and 32, 33 in a block 38 which is mounted on pins 14, 16 in a gimbal ring 12. A further gimbal ring (not shown) is also provided surrounding the ring 12 with a pivot axis at right angles to that defined by the pins 14, 16. The force exerted by the spring 62 is adjustable by means of a screw-threaded plug 58. The shaft 6 may be solid with the rotor of the driving motor which is provided with only one bearing so that this bearing and the rotor form the only supports for the shaft. Otherwise the shaft 6 may be coupled to the shaft of a conventional motor by a resilient sleeve surrounded by a metal cylinder to eliminate wobble. In use the gimbal mounted rotor tends to align its spin axis with that of the shaft 6, but sudden deflections of the shaft 6 will not be immediately transferred to the rotor 2. Thus when used in stabilizing a camera lens, the rotor will be unaffected by vibrations and the like but will be able to follow panning movements.
