Title: Improvements in or relating to bands, or strip-like materials
IPC: F16L3/14
Filed: 1947-12-24
Abstract: 645,853. Straps and bands. WOLD, E. A. Dec. 24, 1947, No. 34189. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 24, 1947.] [Class 109] [Also in Group XXII] A band or strip 1 axially provided with spaced holes 3 at regular intervals, has its sides of such a form, e.g. wavy, that its cross - section throughout the entire length has equal stretching and bending resistance, e.g. is of the same dimension throughout. The band is of relatively rigid material such as iron, steel, brass, copper, hardened rubber or caoutchouc. Two or more such bands, 1, 2, may be joined together by suitable clips, either in such a manner that the holes in the bands coincide or that a hole in one band lies between a pair of holes of the other band. A suitable clip for the former connection comprises a U-shaped member 5 having its base of the same width as the narrowest part of the band and with its legs bent around the overlapping bands. A suitable clip for the latter connection comprises a combined clip-split pin having a base 6, Fig. 3, of the same width as the narrowest part of one band around which it is fitted, and a pair of legs 7, 8 for insertion into a hole of the overlapping band, the legs then being splayed apart as at 10, 11. The bands may be used for tying parts together, to make suspension brackets for tubes or pipes, for securing ceiling suspensions, angle irons &c. Applied to a suspension bracket for a tube, a length of the band 27, Fig. 4, is bent to the shape of the tube and its free ends provided with lugs 28, 29 for attachment by a bolt 30 to another length of the band 31 acting as a suspension strap. The free end of the latter is bent downwardly so that a suspension hook 33, may pass through two holes. In another form, the part 27 and the suspension strap 31 are bent up from a single length of the band, the bolt 30 being replaced by the combined clip-split pin of Fig. 3. The free end of the suspension strap in this case is bent over to form a loop which is anchored by the U-shaped clip described above.

Title: Process for producing electrostatic charge patterns
IPC: G03G5/147
Filed: 1974-08-05
Abstract: 1470443 Electro-photographic process MINNESOTA MINING & Mfg CO 5 Aug 1974 [6 Aug 1973] 34444/74 Heading G2H A latent electrostatic charge pattern is produced on a copy medium comprising a photoconductive layer interposed between an insulative layer and an electrically conductive layer, at least one of which outer layers is radiation transmissive, by: (1) connecting the electrically conductive layer to earth; (2) forming equal electrostatic charges of opposite polarity on the outer and inner surfaces respectively of the insulative layer; (3) earthing the outer surface of the insulative layer so that its charge is partially transferred to the electrically conductive layer; and (4) exposing the photo-conductive layer to a radiation pattern. Process steps (3) and (4) may be performed together. The polarity of the resultant latent electrostatic image on the insulative layer may be reversed by earthing the outer surface of the said layer while flooding the photo-conductive layer with radiation. Charging in step (2) may be effected with a corona device or, if the insulative layer consists of a poled pyroelectric material such as the copy medium described and claimed in Specification 1470444 by heating or cooling the copy medium to develop a charge on said layer, momentarily earthing the outer surface of said layer to discharge it, and then allowing the copy medium to return to ambient temperature whereupon it again develops a charge but of the opposite polarity to the, discharged, original charge. The earthing step (3) may be effected by means of an earthed conductive brush or by a corona discharge. The latent electrostatic charge patterns are developed with toner particles and the toner image transferred to copy paper in conventional manner. By use of a plurality of photo-conductive layers each sensitive to a single but different colour light, or by the use of a single layer containing interspersed groups of colour sensitive layers, colour prints may be obtained.

Title: Microwave induction gauge
IPC: G01N27/20
Filed: 1972-07-24
Abstract: 1333907 Testing for thickness and flaws, electrically LOCKHEED AIRCRAFT CORP 24 July 1972 [18 Aug 1971] 34595/72 Heading G1N A conductive sheet workpiece is tested for thickness, Fig. 1, flaws, Fig. 4, or both by forming a waveguide test head between its surface and a conductive plate having a conductive fin secured thereto transverse to the direction of propagation of micro-wave energy from a source through the test head to an amplitude detector. The detected amplitude varies exponentially with the spacing between the fin and the surface. In Fig. 1 two test heads are used and the outputs of the detectors 17, 18 are multiplied at 21 to give a measure of x + y. A voltage representing the spacing between the fins 41 and 42 is subtracted at 22, the resulting signal representing the thickness of the sheet 24. Each test head has a longitudinal recess (40) carrying a longitudinal fin (32) to minimize leakage, Fig. 2 (not shown). In Fig. 4 the test head 52 has two mutually perpendicular micro-wave paths defined by recesses 50, 51 each carrying a fin (55, 56), Fig. 5 (not shown). The ratio of the outputs of amplitude detectors 66, 67 is formed at 68 to detect flaws, compensated for relative motion between the head and the workpiece. Two such heads may be arranged either side of the sheet workpiece to test for flaws and measure thickness simultaneously. Coupling between the source and the waveguide test head is through transducers 61, 62 comprising displaceable pistons (76, 77), Fig. 6 (not shown) and an aperture (72).

Patent GB-761470-A (GB)
Title: Improvements in or relating to protective arrangements for alternating current circuits
IPC: H02H3/347
Filed: 1953-12-15
Abstract: 761,470. Protective cut-out arrangements. GENERAL ELECTRIC CO., Ltd., and HARWOOD, A. E. J. Dec. 9, 1954 [Dec. 15, 1953; May 6, 1954], Nos. 34905/53 and 13259/54. Class 38(5) In a protective arrangement the coil 11 of an earth leakage relay EL is energized by the secondary winding 2 of a corebalance transformer 1 to cause the opening of a contactor 8 in the event of a fault and the coil 11 is then maintained in an energized condition independently of the fault path. In Fig. 1, on the occurrence of an earth fault 43, the winding 2 is energized by the out-of-balance current and energizes the coil 11 through a full-wave rectifier 10. The relay EL opens its contacts 12, to cause the opening of the contactor 8 and the de-energization of the motor 6. It also closes contact ELNO1 to short circuit a resistor 18 so as to apply full voltage from a voltage transformer 13 to a winding 3 on the core-balance transformer 1 to maintain the winding 2 energized on the opening of the contacts 8. Contacts ELNO2 of the relay EL are closed to energize an indicator lamp 20 and contacts ELNC1 are opened to open a circuit including auxiliary contacts 8NC1, 8NC2 of the contactor 8 between the winding 3 and one of the phase conductors. Resetting is effected by opening an isolator 7 to de-energize the transformer 13, windings 3, 2, and the coil 11 so as to restore the contacts of the relay EL to the positions shown. On reclosing the isolator 7, the coil 11 of the relay remains deenergized if the fault has been removed, but if the fault persists, then the winding 3 is energized from the transformer 13 through a circuit including the contacts ELNC1, 8NC1, 8NC2, fuse 19, a phase conductor, the fault path 43 and earth. Thus the relay EL is operated and the system reverts to the condition in which the winding 3 is supplied through the contacts ELNO1 and not through the fault path. During this attempted resetting the contactor 8 does not momentarily reclose as it remotely controlled by a "start-run" switch, e.g. as in Specification 743,983. The winding 3 may serve as a test winding under the control of a switch 17. In Fig. 2 (not shown), the earth leakage relay is mechanically coupled to a reset relay and after a fault has occurred is maintained energized through circuits which do not involve the use of the test winding on the core balance transformer.

Patent GB-633085-A (GB)
Title: Improvements in or relating to regulating systems for dynamo electric machines
IPC: H02P9/36
Filed: 1946-11-28
Abstract: 633,085. Automatic voltage control systems; dynamo-electric machines. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 28, 1946, Nos. 35296, 35297 and 35298. Convention dates, Nov. 29, 1945. [Classes 35 and 38 (iv)] In a regulating system for a dynamo-electric machine supplying a load, the machine exciter has a control field which is supplied with D.C. from either the exciter or the load, through a network embodying a non-linear parameter, to effect energization of the control field correctively upon the sudden application of load. In Fig. 1, the bus-bars 16, 18, 20 are supplied from alternator 10, the field 14 of which is energized from the exciter 22. With the controller 44 as shown, the exciter control field, 34, which is normally de-energized when generator 10 is maintaining the predetermined line voltage and which is directionally energized to maintain the line voltage substantially constant, is supplied by the line -voltage through the positive phase sequence network 50, frequencycompensating network 48 and the voltage reference network 46. With controller 44 operated to connect the winding 34 to the manual control circuit 76, the output voltage of exciter 22 is maintained constant and in the event of a reactive load or a short-circuit being suddenly applied to the generator 10 the consequent rise in the output voltage of generator 22 is gradually restored to the normal value, during which time circuit-breaker coordination may be obtained, or may be adjusted manually to effect the restoration rapidly. Where a number of generators are operated in parallel, a failure in the regulating system of one may cause a reversal of the polarity of the exciter generator 22 and a rise in its output voltage. This last condition may be corrected, Fig. 2, by switching in the control circuit 76, the rectifier 89 of which permits a current flow through the control winding 34 so as to lower the voltage of 22 which may be further adjusted by the tapping 84. Changes in the output of 22 consequent upon transient conditions in busbars 16, 18, 20 are gradually reduced to effect a slow restoration of the normal output voltage of generator 10. In a further embodiment, not shown, the control circuit 76, as employed in Fig. 1, is energized from the output of generator 10 through the rectifier bridge 92 and operates to maintain reactive or S.C. loads to effect circuit-breaker co-ordination. Specification 623,209 is referred to.

Abstract: 605,745. Steering gear. BISHOP, R., and JOHNSTON, R. H. Dec. 31, 1945, No. 35306. [Class 79 (v)] A steering gear for a road vehicle comprises a rigid track rod slidably mounted and connected at each end by a link member to a - steering arm and a drive including a flexible element, e.g. a chain, for converting rotary movements of the steering shaft into reciprocatory movement of the track rod, the flexible element being wrapped round a driving part on the steering shaft and passing round guide means on the track rod and having its ends secured to a fixed part of the chassis frame, so that linear displacement of the track rod is less than that of the flexible element. The track rod 1, Fig. 1, is slidably mounted in a housing 3 and is secured at its ends by universally jointed links 2, Fig. 1A, to the steerable wheels in a normal manner, bellows 4 being provided to prevent ingress of dirt. Fixed to the housing 3 at 9 are the ends of a flexible chain 8 which passes round guide pulleys 5, mounted on the track rod, guide pulleys 12 mounted on the housing, and round the sprocket 10 secured to the end of the steering shaft. This arrangement gives a 2 to 1 reduction between displacement of the chain 8 round the sprocket 10 and displacement of the track rod. The end of the steering shaft may be mounted in an eccentric bush provided with a clamping ring, to permit adjustment of the chain tension. Instead of a single flexible member, two may be used.
