Title: Improvements in or relating to locomotive driving gears
IPC: B61C9/40
Filed: 1926-06-09
Abstract: 270,911. Marks, E. C. R., (Swiss Locomotive & Machine Works). June 9, 1926. Connecting-rods.-In a locomotive driving gear of the kind in which the drive is transmitted from one or more electric motors through toothed gearing to a lay shaft and thence by means of cranks and connecting rods to triangular coupling rods connecting two adjacent driving axles, the upper head 13 of the triangular coupling rod 8 to which the connecting rod 14 is pivoted is arranged near that end of the triangular coupling rod which is remote from the lay shaft 4 to provide for a comparatively great length of the obliquely arranged connecting rod. The head 13 is also at such an elevation above the heads for the crank pins 6, 7 that the connecting rod 14 clears the pin 7. The heights H and H' may be respectively one tenth of the dimensions L and L<1>. Means for adjustably coupling to a third driving axle 3 are also described. The end 15, Fig. 4, of the coupling rod 10 is forked to embrace an extension 16 of the triangular coupling rod 8, and the parts are connected by a pin 17 having conical bearing ends 19, 20 in the fork 15 and an eccentric cylindrical portion 18 passing through the part 16, the length of the coupling rod 10 thus being adjusted by rotation of the pin. To lock the pin 17 in adjusted position, a toothed disc 21 fitting a squared part 22 of the pin is engaged by a locking plate 23 secured to the fork 15 by set screws 24. Both ends of the plate 23 are toothed, the teeth being so arranged that by reversing the plate an adjustment corresponding to half the pitch of the teeth can be obtained.

IPC: H01R43/10
Filed: 1955-05-20
Abstract: 819,634. Non-metallic tubes. ENGLISH ELECTRIC CO. Ltd. May, 16, 1956 [May 20, 1955], No. 14597/55. Class 99(2). [Also in Groups VIII, XXV and XXXV] A method of making a lap-jointed split ring comprises the steps of winding an inner part of the ring from a tape treated with a bonding material, applying to a portion of the outer rim of this inner part of the ring to correspond with the required overlap at a joint a piece of material (12) which is non-adhesive with respect to said bonding material, winding around the inner part of the ring an outer part from tape treated with bonding material, causing or allowing the bonding material to harden as by heat treatment or by a natural setting process, and splitting the composite ring so formed by a substantially radial inward cut (CD) made from the outside of the ring to one end ofthe piece of non-adhesive material and a substantially radial outward cut (EF) made from the inside of the ring to the other end of the said piece of material followed by an extraction of the piece of non-adhesive material. The tape may be of woven glass and the bonding agent a casting resin, e.g. " Araldite " (Registered Trade Mark) casting resin F. The non-adhesive material may be polytetrafluorethylene. The ring may be wound on a mandrel from a single length of tape treated with bonding material, the winding being halted when the ring is partially formed and said non-adhesive material inserted at this stage, after which the winding is completed. A similar technique can be used for producing half-tubes which will mate together satisfactorily to form a complete tube having more than one lap joint in it. A split ring made in accordance with the invention may be used as a dust barrier between the slip rings of an electrical machine, and the joint DF then bonded by using the above-mentioned casting resin. A single layer of tape may be applied around the ring to cover the joint gap.

Title: Apparatus for the signal-to-noise ration of a received signal
IPC: G01S13/87
Filed: 1971-05-14
Abstract: 1327834 Diversity reception; interference suppression COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT ALCATEL 14 May 1971 [15 May 1970] 14978/71 Headings H4J and H4L In a system for combining two narrow band signals S1 and S2 and improving the signal-tonoise ratio, the two signals having a constant frequency f 0  = 1/T 0  and being evolved from a common signal but having different noise levels, the signals are derived from a pair of inputs 11, 21, e.g. aerials, made identical in amplitude and phase in amplifier and narrow band filter circuits 12, 22 respectively and added at 32 and subtracted at 33 to provide signals U, V respectively; signal V consisting substantially of noise. There will be no correlation between the signals and either noise level, but due to the use of narrow band filters centred around f 0  there will be some correlation between the noise levels themselves. The difference V is supplied to an amplitude regulator 40 which may comprise an amplifier with a.g.c. or an amplitude limiter and narrow bandpass filter centred on f 0 , which provides an output T whose mean quadratic value is substantially constant and which has a waveform identical to that of V. The output of regulator 40 is supplied to a correlator 42 whose second input is the output U of the adder 32, which forms the product of the two signals and after either integrating the product or passing it through a low pass filter, provides a slowly varying unidirectional voltage UT proportional to the mean value of the product. The output of the correlator and the output T of the regulator are multiplied at 43 to provide T.UT which is supplied to an adder 50. Output T is also delayed by an amount T 0 /4 at 45 to provide an output T<SP>1</SP> which is supplied to a correlator 47, identical to the correlator 42, together with the sum signal U, the output of the correlator 47 being multiplied at 48 with the output T<SP>1</SP>. The resulting output T<SP>1</SP> UT<SP>1</SP> is supplied as the other input to the adder 50 and the resulting output P is subtracted from the sum signal U at 52 to provide the improved signal S 0 . A mathematical analysis is included in the Specification and it is stated that where the two noise levels have the same waveform but differ only in amplitude and phase, the output noise level may be reduced to zero. If the respective powers of the two noise levels are equal, the apparatus may be simplified, Fig. 2 (not shown) by the omission of elements 42, 43 and 50. One of the inputs may consist only of noise and in this case a signal with accompanying noise is applied at point 34 and noise only at point 35.

Abstract: 1427382 Magnetic storage arrangements; controlling light BRITISH BROADCASTING CORP 1 July 1974 [29 March 1973] 15200/73 Headings H3B and H4F A matrix pattern of magnetic bubles in a thin magnetic sheet is produced by distributing serial electrical digital information among bubbles generators in parallel channels, the bubbles according to their presence or absence in defined spatial positions modulating a beam of optical radiation for recording a corresponding image on a light sensitive material such as a photographic film. As shown binary pulses in a line 18 are applied over a commutating switch 20 which distributes the incoming pulses to bubble generators 14. From each generator the bubbles developed in sheet 10 are propagated by clock pulses along rows of bubble locations 12. When the matrix pattern is fully entered in the sheet, recording of the image is effected by an incident polarized light beam. Thereafter the bubble pattern is erased in preparation for entry of a further pattern by advancing the bubbles to annihilators 16. The magnetic sheet may be backed by an integral polarization analyser. Additionally a uniformly apertured digit plate may precede the magnetic sheet to improve accuracy. An analyser need not be used if holographic recording is required. In a modification the optical beam may be modulated by reflection from the magnetic sheet or by an array of light valves controlled by and formed integrally with the magnetic sheet.
