Abstract: 172,681. Alexander, A. E., (Stuart Electrolytic Cells, Inc.). Aug. 4, 1920. Oxygen and hydrogen, generating; electrodes; supporting; cells; diaphragms.-A bipolar electrode comprises a vertically arranged rectangular metallic strip preferably of uniform cross-section, having its major plane arranged in the direction of the flow of the current to and from the strip. In a cell, Fig. 3, for generating oxygen and hydrogen, the electrode 1 and the end electrodes 2 abut against diaphragms 3, pervious to the electrolyte but not to gas. Air-tight partitions 4, which need not be insulating, are arranged on either side of the strip to divide the space between the diaphragms. Two or more bipolar electrodes may be arranged in series. In a cell shown in sectional plan in Fig. 5, a large number of strips 1 are arranged side by side separated by the partitions 4, and two sets of strips are arranged in series, with separating diaphragms 3, between the end electrodes 2. As shown in side elevation in Fig. 6, the strips and partitions are formed with slots in which are inserted metal bars 9 held in co-operating recesses in frame sections 11, 12. The bars 9 have end lugs 14 which pass through the side walls of the frame. The end electrodes 2 are secured together in contact with bus-bars 17. The frame sections are secured together by bolts 19, the joints being made air-tight by paint, cement, or the like. Each unit may comprise 700 parallel strips each of dimensions inch in the direction of current overflow and 24 inches in the transverse direction. The spacing members may be 3/16 inch wide and of such thickness that one ormore of them serve to space the strips 1/32 inch apart. Each strip may carry one ampere of current. The strips may be of foil or gauze.

Patent GB-272075-A (GB)
Title: Sound-reproducing machines
IPC: G11B17/02
Filed: 1926-03-09
Abstract: 272,075. Brenchley, R. March 9, 1926. No Patent granted (Sealing fee not paid). Driving; speed-regulating; starting and stonping.-Relates to gramophones of the kind in which either an electromotor or a spring motor may be used alternatively for driving the machine. According to the invention, both machines are normally geared to the turntable, and when the spring motor is in operation, the rotor of the electromotor is driven idly by it; when, however, the electromotor is switched on, as soon as the spring is fully run down, the drive between the spring barrel and the turntable is automatically interrupted, whereby unhooping of the spring from its barrel is prevented. A single device for regulating the speed, and for stopping or starting either motor may also be provided. As shown in Figs. 1 and 2, the turntable spindle 2 carries a worm wheel 30 gearing with a worm 29 on the shaft 27 of the electromotor 25, and also carries a pinion 35 which is adapted to connect with the spring barrel 26 through a gear train 34, 23, 31. A speed governor 28 may be mounted on shaft 27. The spindle 33, on which the wheel and pinion 34, 32 are fixed, is mounted in curved slots 42 in the framework plates 23, so that the spindle is capable of a certain amount of lateral movement. With this arrangement the pinion 32 is always in engagement with the teeth 31 of the spring barrel, and the wheel 34 gears with and drives the pinion 35 when the spring motor is in use; but when the electromotor is in action, and the spring is fully distended, the resistance offered by the teeth 31 causes the spindle 33 to be displaced so that the wheel 34 moves out of mesh with the pinion 35. Figs. 7 and 8 show a combined speed-regulating and stopping and starting device. A socket 43 is slidable lengthwise from a screw 44, and can also rotate it by means of a pin 45. The screw bears against a lever 46 carrying a friction-pad 47 coacting with the governor disc 48, and can thus be adjusted by rotating the socket 43, to regulate the speed. When the part 43 is moved endwise, its tapered end 43<1> allows a blade spring 49 to bring a brakeblock 50 into contact with the disc 48. At the same time, contacts 51, 52 in the motor circuit (one of the contacts being on the spring 49) are opened. A slightly modified arrangement of the switch and brake is described. Specification 249,104 is referred to.

In position sensing equipment of the type comprising two relatively moveable gratings and two scanning devices spaced apart by half the period of the gratings or the light pattern produced thereby, odd harmonics are eliminated by making the width of the grating strokes S = m 1  P / n and the gaps between the strokes L = m 2  P / n where P is the period length of the grids, n is the ordinal number of the harmonic to be eliminated and m 1  + m 2  = n. Even harmonics are eliminated as in the prior art by applying the signals from the scanning devices to a subtractor circuit. Odd harmonics may be further reduced by slanting one grid relative to the other by an angle α = P/nH where H is the height of the grid strokes. In an embodiment, Fig.5, (not shown) in which one grating is imaged into the other by lenses an aperture is inserted between the lenses to eliminate all harmonics higher than n = P/F# where P is the period length of the signal, F the f-number of the aperture and # the wavelength of light used. The aperture may be in the form of a slit of width P/F# or a grating. The sine and cosine signals produced by the scanning devices may be applied to the X and Y plates of a cathode-ray tube to move the spot along a circular locus to a position indicative of the relative position of the gratings.

Abstract: 1343241 Controlling traffic signals EVG ENTWICKLUNGS-U VERWERTUNGSGESELLSCHAFT mbH 23 May 1972 [25 May 1971] 24248/72 Heading G4Q In a traffic signal installation, a control circuit includes a clock pulse generator, a pulse counter and one or more RC circuits; switching means responsive to the counting of the pulses and the RC circuit(s) operate to switch the signals at the ends of certain phases in dependence upon the counted pulses and at the ends of the other stages in dependence upon the operation of the RC circuit(s). In a preferred form, the switching at the ends of the relatively short phases is controlled by the RC circuits, while that at the ends of the relatively long phases is controlled by the counted pulses. Thus, any timing errors which may result from operation of the RC circuits are periodically erased to prevent their building up; this is significant where the installation is one of a series of synchronized installations along a roadway arranged to provide, by their successive changing to the green phase, for continuity of traffic flow. In the embodiment shown a respective one of four pulse-counting program switch panels 3-6 is associated with each of four groups of signals (Fig. 1, not shown) at a cross-roads. The circuitry is described only with reference to the panel 3 which has two output terminals A, B each of which delivers pulses at regular, programmed intervals. A pulse at terminal A passes to switching logic circuit 9, hence to a lamp ignition control circuit 10 and, via triac 11, to lamp 12 to cause a "green pulsating" phase. This pulse also starts charging of RC circuit 19 which, when charged, delivers a pulse to circuit 9 to cause cessation of the "green pulsating" phase and initiate an "amber" phase. The output of RC circuit 19 also starts an RC circuit 21 which, when charged, delivers a pulse which ends the "amber" phase and initiates a ''red" phase. Subsequently, a pulse is delivered from panel 3 to its terminal B. This acts on circuit 9 to terminate the "red" phase and initiate a "red and amber" phase, as well as starting an RC circuit 20 which eventually delivers a pulse to terminate the "red and amber" phase and initiate the "green" phase. Termination of the "green" phase is caused by a further pulse at terminal A, which also initiates the "green pulsating" phase of a new cycle. Each panel 3-6 contains a number of contact sockets, one for each switching period, and each socket contains four make contacts and four change-over contacts. A number of program contact plugs, each with a number of binary-coded switching cams, is provided. Insertion of a given plug into a socket results in the determination of the length of that switching period before the delivery of a pulse from the terminal A or B. The operation of the switching logic circuit 9 (which comprises four logic circuits (91-94) (Fig. 4, not shown) in forwarding the switching commands to the signals, is described. The time constants of the RC circuits are adjustable.

Abstract: 922,232. Sewing, boots &c. seams. E. ORLANDO. July 15, 1959 [July 15, 1958], No. 24302/59. Classes 112 and 17 (2). [Also in Group VIII] A seam joining two pieces of flexible sheet material is produced by slitting down the edge of at least one piece to form two lips, butting the edge of one lip against the edge of the other piece or against the edge of one lip of the other piece, joining the abutting edges, and folding down the other lip or lips so as to cover or partly cover the join. The joining may be effected either by sewing or by gluing. The slit may vary in depth and in inclination to the surface of the material. The edges may be straight or curved. In Fig. 3 an edge of a piece 9 and also of a piece 10 is slit to form a lip a and a lip b. The lips b are abutted and are joined by a stitching 11 which is then covered by the lips a. In Fig. 4 the edge of a shoe upper is slit to form lips a and b. Lib b is sewn to the inner sole 18, and lip a is either moved inwards to cover the join or is splayed outwards and is sewn to the sole 19.
