Title: Improvements relating to electrical power couplings
IPC: H02H9/02
Filed: 1965-08-17
Abstract: 1,115,056. Excess current protection arrangements. LICENTIA PATENT - VERWALTUNGS G.m.b.H. 17 Aug., 1965 [17 Aug., 1964], No. 35207/65. Heading H2H. A coupling for an A.C. system comprises a circuit-breaker in series with a series-connected inductance capacitance combination which is tuned to the frequency of the system and has a long time constant to delay the increase in fault current sufficiently to allow the circuitbreaker to trip before the fault current reaches its maximum value. To this end the combination has a relatively high inductance and a low capacitance, the inductance having a low ohmic resistance. If the time constant cannot be made sufficiently high, the delay can be increased by repeatedly shunting the capacitor by a damping circuit until the breaker has tripped, which action may not be necessary if the fault current is limited to a tolerable value. The shunting may occur at instants when the voltage across the capacitor reaches a maximum value and may be effected by surge diverters, spark gaps, voltage dependent resistors, controlled rectifiers or saturable reactors.

Abstract: 1,204,857. Door sliding mechanism. DYSONA INDUSTRIES Ltd. 4 April, 1968 [18 April, 1967; 24 April, 1967; 18 May, 1967; 24 July, 1967 (2); 1 Aug., 1967 (2)], Nos. 17817/ 67; 18798/67; 23090/67; 33878/67; 33880/67; 35245/67; and 35246/67. Headings E2A, E2M and E2X. [Also in Divisions F4, H1 and H5] A micro-wave cooking oven has a front door 10 with strips 28 (Fig. 5) on its sides sliding between guide members 18, 20 provided on the oven and covered with extruded low friction plastics (22, 24, Fig. 3). Since the oven front face 16 and the front wall of the door are respectively at an angle to the guiding slots and the strips 28 the door is wedged towards the oven face in the final portion of its manual closure, and it is maintained closed through permanent magnets (17, Fig. 1A) acting on the mild steel door frame through a non-magnetic stainless steel lip. On termination of a heating cycle, the microwave supply is automatically cut-off and two solenoids 40 are energised. Each solenoid carries, a plate 44 that on energisation rises and lifts the door through a sliding block 34 (Fig. 5) on which the door rests and which it engages through a prong (30, Fig. 5), a spring 46 biasing the plate 44 upwardly into contact with block 34. The plate stops at the full line position of Fig. 2 on de-energisation of the solenoids, and since the effect of the magnets (17) has been overcome, upward movement of the door is continued by counterbalance springs 38 connected to blocks 34 through steel tapes (36, Fig. 5). When the door is thus opened blocks 34 are brought to a halt by engagement with stops provided by the boxes of the counterbalance springs 38, but the door continues to move upwards for a short distance before falling back onto the blocks. The door, which includes a perforated inspection panel (12, Fig. 1), is removable for cleaning from the guides 18, 20.

Abstract: 324,468. Hopkinsons, Ltd., and Brearley, D. B. Nov. 30, 1928. Pressure gauges.-Comprises the combination with a dead weight of resilient variable loading means, the arrangement being such that no movement of the indicating needle takes place until a predetermined pressure is exceeded, after which the movement is controlled by the variable loading means. The fluid pressure acts on a diaphragm a combined with a piston b sliding in a cylinder c. The piston acts on the short arm of a lever d which is connected by a link e to the short arm of a lever g moving about a fulcrum f and carrying a dead load h. A spring i connects the lever g to the casing. The end of the lever g is connected to an indicating jointer j moving over a scale j'. The weight h is adjusted so that no movement of the pointer takes place until the predetermined pressure is able to overcome the influence of the weight h, when further movement is resisted by the diaphragm a and spring i only. A finger m may record on a moving chart n. In a modification a differential piston is used with a diaphragm at each end. In a further modification the weight h may be moved along the lever g by a screw carried on and parallel with the lever.

Abstract: 1462128 Delivering sheets; guiding elevating platforms I D Inc 12 Aug 1974 [15 Aug 1973] 35459/74 Headings B8R and B8L A sheet stacker comprises a table 18, Fig. 2, vertically movable in a frame 10, the upper surface of the table being formed of rotatable rollers 24, Figs. 1 and 2. A self-levelling device for the table comprises a torsion bar 70 at either side of the table, each bar carrying sprockets 72, 74 at each end. A chain 76 is secured to the frame at 78 above the table, passes under one sprocket 72 and over another sprocket 72, and is secured to the frame at 80 below the table. A chain 82 is similarly but oppositely arranged in engagement with sprockets 74, being secured to the frame at 84, 86. Similar chains 76, 82 are arranged at the other end of the table. Raising or lowering of any corner of the table thereby results in raising or lowering of the other three corners. The table is raised and lowered as a whole by pistons 36 in hydraulic cylinders 38, each piston actuating a chain 28 secured at its lower end 30 to the table and at its upper end to the frame and passing over a sprocket 34 attached to the piston. There are two chains 28, one at each of two diagonally opposite corners of the table. The pistons are actuated by a three-way valve 42, which enables the table to be raised, lowered or held stationary, the fluid being supplied by a low-capacity hydraulic pump 48 for slow movement or by pumps 48 and 50 for rapid movement. The rollers 24 are driven by a chain 64 passing under sprockets 26 on the end of every second roller and over intermediate idler sprockets 26, and also passing over a fixedly mounted sprocket 68 and a sprocket 66 mounted on the table, and the chain is driven by an hydraulic motor 62 controlled by a solenoid valve 60, the fluid being supplied by the pumps 48 or 48, 50 for slow or rapid motion. The pumps are driven by an electric motor 51. The valve 42, pumps 48, 50 and valve 60 are actuated by an electrical control circuit 44. In operation, with the table in its upper position, sheets delivered from a corrugating machine by a belt 88 assisted by an idler roller 102 engage a stop member 94 and form a stack 92 on the table. When the stack reaches a predetermined height, the light path to a photo-electric detector 96 is blocked and the table is lowered until the path is free, thus moving down intermittently until it engages a microswitch 110, whereupon a solenoid 108 is energized to lower a gate 104 to prevent entry of further sheets, while the rollers 24 are rotated first slowly and then rapidly to eject the stack. After a delay, the table is raised rapidly until it strikes a microswitch 112 and then slowly until it strikes the stop 94, whereafter the gate is opened.

Void [Published under Sect. 91 of the Acts]. [Classes 97 (i) and 98 (ii).] In order to take, on a linear lenticular film, colour-record component images which are.formed on the sensitive layer exactly vertically under their corresponding lenticular elements, the colourband screen is placed in the front focal plane of the objective instead of in the plane of the diaphragm, and comprises several of the usual sets of colour bands arranged in parallel juxtaposition, the width of each set being made equal to F.d/f, where F is the focal length of the taking objective, and d and f are respectively the diameter and focal length of a lenticular element. A colour-record film so produced may be projected in any projection apparatus, provided that there is placed in the front focal plane of the objective a colour-band screen also comprising several sets of colour bands, each set being, however, of width F<1>, d/f, where Fl is the focal length of the projection objective. Dominant lines are avoided by using in the taking and projecting objectives a rectangular diaphragm whose width, taken at right-angles to the colourbands, is such that in each case only one set of colour-bands is visible from any point of the picture plane. Specification 10611/09, [Class 98 (ii), Photographic processes &c.], is referred to.

Title: Interference suppression system
Inventor: SINNINGER DWIGHT VIRGIL
IPC: H04B1/12
Filed: 1963-09-12
Abstract: 1,062,943. Radio receiving systems. SENN CUSTOM Inc. Sept. 12, 1963, No. 35964/63. Heading H4L. An interference suppression system in a radio receiver comprises a pair of spaced aerials and means for varying the relative amplitude and phase of the signals from the respective aerials so that the wanted signals are combined additively and the interfering signals are balanced out. As shown in Fig. 2, the signals from the two aerials are supplied via resistors 14, 16, which are adjusted to equalize the amplitudes of the interfering signals, to the respective ends of a delay line 62 comprising a winding 54 on a conductive non-magnetic core 56 which is earthed at each end, and an adjustable coupling coil 60 for effecting the required phase balance. The output of the coil 60 is supplied via a cathode follower 48 to the radio receiver 50. In a modification, Fig. 1, not shown, the delay line is of linear form and the coupling coil is movable within the hollow core of the delay line. In a further arrangement, Fig. 3, the interfering signals from aerials 10, 12, are balanced as regards amplitude by a potentiometer 124. The resulting signals from potentiometer 68, 70 are supplied via a changeover switch 76 to a balun in the form of twisted conductors 78, 88 wound on a ferrite core, which converts the unbalanced input into a balanced output for application to an R.C. phase-shifting network 86,84,92,94. The output from the potentiometer 100, 102 is fed direct via a similar balun 106 to phase-shifting network 86, 116, 118, 120, the required phase balance being achieved by adjustment of potentiometer 86. The changeover switch 76 doubles the amount of phase shift available. A tuned circuit 126 combines the outputs of the two phase-shifters for amplification at 138. With balanced aerials the baluns are omitted and the output signals may be combined by application to the respective control grids of a pair of valves with a common cathode output impedance. In a further arrangement the two signals are combined by means of a pair of ferrite cores with separate input windings but linked by a common output winding. The amplitudes may be balanced by means of adjustable transformers in the respective aerial circuits. An arrangement using two pairs of aerials to eliminate two interference signals is described, Fig. 8 (not shown), the signals from each pair being first combined as previously described and the resulting pair of signals being combined in like manner.
