Title: Improvements in or relating to the toning of bromide photographic prints by the hypo-alum process
IPC: G03C5/46
Filed: 1932-08-05
Abstract: 396,935. Toning photographic prints. WEST, S. D., 64, High Street, Whitstable, Kent. Aug. 5, 1932, No. 22007. [Class 98 (ii).] The hypo-alum process for toning developed bromide prints is modified, in order to reduce the time required, by first treating the developed print for about 10 minutes at ordinary room temperature in a hypo-alum fixing bath, and then subjecting it to the action of hot water vapour for a short time, for example for 2-2¢ minutes with vapour at 50- 60‹ C. The developed print strip m may be fed, from the hypoalum bath, in a zig-zag path round a vertical chamber a at a speed adjusted to the desired duration of treatment, the chamber being filled with hot water vapour produced by electrically heating, as by an immersion heater i, water in an open tank h. The strip enters and leaves the chamber through its base. The chamber has sliding doors b, and is fitted with a thermometer. A formula for a hypo-alum bath containing a liquid hardener is given in the Specification.

Title: Improvements in or relating to electromagnetically actuated hammers, drills, vibrators, and other reciprocating or vibrating tools or devices
IPC: B25D13/00
Filed: 1925-09-05
Abstract: 258,725. Grant, P. Sept. 5, 1925. Reciprocating machines; solenoids.-A reciprocating motor comprises three coaxial coils placed end to end, the outer pair of coils being connected to one and the middle coil to the other of two electrical supplies, alternating and continuous, and the outer coils having similar magnetic polarity at their adjacent ends. A movable core is placed within the middle coil, and a further core is fixed or spring-mounted within one or each of the outer coils. In the form shown in Fig. 1, the continuous and alternating-current coils 6 and 5, 7 respectively are clamped by bolts 10 between end plates 8, 9 and are enclosed between an outer casing 11, made of mutually insulated segments, and inner tubes 3 and separators 4 which surround a central guide tube 1 preferably of nonmagnetic material. If made of metal, the tube 1 is of high-resistance material or is split longitudinally. The two sets of coil leads are brought to terminal blocks 17, 18 on a cover over a hole 15 in the casing 11. The central loose core 19 receives constant polarity from the coil 6 and the end cores 20, 25 receive alternating polarities at their inner ends which are similar at any instant, due to the alternating-current coils 5, 7. The lower core 25 is fixed and is traversed by the shank 26 of the tool which projects beyond the inner end of the core. The upper core 20 is spring-supported against a cap 22 and is adjustable by means of nuts 23 on a tail rod 21. Fig. 3 shows a form in which the coils 5, 7 are separated from the central coil 6 by annular distancepieces 32a within which move the transverse polepieces 34, 35 of the central core 19. The lower end of this core has a hardened striker 38 bearing on the tool shank, and the upper end extends into a hole in the upper core 20 which is spring-supported, as in Fig. 1. The alternating-current bobbins are made of insulating tubes 39 and end plates 40 which are preferably of laminated soft iron and form magnetic pole faces. The coils are interlaced with soft iron strips or wires 41. A trigger switch 43 controls the main switch 44. Fig. 4 shows a form comprising two coils 48 and a split coil 49, respectively supplied with alternating and continuous current similarly directed in the coils 49 and oppositely in the coils 48. Fixed cores 51, 52 project into the ends of the coils which are spaced apart and preferably separated by a magnetic filling 50. The coils 49 impart constant polarity to the core 19 while the coils 48 give tne poles 51, 52 alternating polarities. whereby the core 19 is reciprocated. The invention is applicable to the operation of hammers, drills, chipping tools, riveters, pumps, compressors, pipe drivers, spades, shaking or ramming in moulding machines, shaking tables, and other purposes.

Title: Improvements in or relating to data transmission systems
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04L1/16
Filed: 1960-06-24
Abstract: 910,453. Error-correcting telegraph systems. STANDARD TELEPHONES & CABLES Ltd. June 23, 1961 [June 24, 1960], No. 22221/60. Drawings to Specification. Class 40 (3). In a data transmission system data is transmitted in blocks of signal elements each block being stored at the transmitter. Each block is preceded by a sequence number and, at the receiver, is checked for errors. Supervisory signals sent from the receiver to the transmitter indicate to the transmitter whether the next block is to be sent or the stored block repeated. If the stored block is to be repeated its sequence number is altered so that the normal sequence of the numbers is disturbed. This alteration may take the form of complete inversion of the elements of the sequence number. If the receiver receives neither the expected sequence number nor its inverse the receiver distributer waits for two successive blocks whereby it can be deduced whether the uninterpretable signal was the sequence number or its inverse. Specification 711,901 is referred to.

Abstract: 650,142. Converting. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Aug. 24, 1948, No. 22266. Convention date, Aug. 27, 1947. [Class 38 (ii)] A voltage multiplier comprises three parallel columns 21, 22, 23, each column consisting alternately of condensers X, Y and rectifiers R connected in cascade by connections 30, 35, 37 between the columns so that the upper end of a rectifier in one column is connected to the lower end of a rectifier in another column. The A.C. supply is fed by way of a transformer 43 to the series combination of a condenser 46 and a rectifier 33, the condenser 46 being insulated from earth while the lower ends of column 22, 23 are earthed. The upper end of the multiplier which forms one of the high-voltage terminals is constituted by a body 41 shaped to prevent corona discharge. By this arrangement of condensers and rectifiers the overall height of the multiplier is less than that in the conventional construction. The rectifiers may be of the metal type or gas discharge valves and if control grids are introduced into the valves the apparatus may function as a voltage reducing inverter. To obviate the need for taking the high voltage leads through the casing enclosing the multiplier, a consumer apparatus may be enclosed with the multiplier.

Abstract: 938,082. Centrifugal pumps. WATEROUS CO. June 27, 1960, No. 22508/60. Class 110 (1). The invention relates to a centrifugal pump of the type in which impellers may selectively operate in series or in parallel with each other. Two impellers 21, 22 on a shaft 20, driven from gearing 47, are separated by a partition wall 15. The discharge volute of the first impeller 21 is connected by a passage 66 to the housing 70 of a transfer valve 69 which is rotatable by a lever to connect the passage 66 with either a passage 72 leading to the intake port 65 of the second impeller to connect the impellers in series or a second passage 73 leading to the discharge passage from the second impeller to connect the impellers in parallel. When the valve is in the first position the force of the fluid in the passage 72 swings a flap valve 83 (see Fig. 5) into a position where it closes the passage between the inlet chamber of the second impeller and the intake manifold 74. In the second position of the valve fluid passes from the manifold into the intakes of both impellers.
