Abstract: 498,565. Two-part couplings combined with switches. MATERIEL ELECTRIQUE DE SECURITE SOC. ANON. Feb. 26, 1938, No. 6164. Convention date, Feb. 27, 1937. [Class 38 (i)] The two parts of a plug-and-socket coupling are fastened together by a turning movement which also operates a mercury-switch in a closed chamber. When the member 35 is applied to the fixed member 1 which is mounted on a vertical surface, pins 21 enter sockets 46 and press the latter inwards against springs 49 until spring contacts 50 engage studs 53 so that the leads attached to the terminals 47 are connected to the contacts 46. A flange 36 depresses locking pins 27 so as to release a rotatable block 12 carrying the pins 21. Hooks 32, 38 enter slots in the opposing rims and are engaged with lateral ramps by turning the member 35 by means of a hand wheel 41. The block 12 is thus turned bringing spring contacts 10 thereon into engagement with sectors 7 attached to the terminals 8 of the supply leads. Finally mercury in chambers 19 bridges the space between the plugs 20 carrying the pins 21 and the studs 18 connected to the contacts 10. A spring-pressed ball 34, holds the coupling against disengagement.

Title: Apparatus for displaying a graphical representation of an electrical signal
IPC: G01D9/16
Filed: 1976-02-18
Abstract: 1501547 Cathode-ray tube circuits HONEYWELL Inc 18 Feb 1976 [19 Feb 1975] 06343/76 Addition to 1321880 Heading H4T Apparatus for displaying and recording representations of a time-varying electrical input signal comprises a sampling circuit for repeatedly determining the maximum and minimum values of the signal during successive sampling periods and displaying (e.g. on a cathode-ray tube) the differences between such values as a number of parallel straight lines extending between points representing the maximum and minimum values. As shown in Fig. 1, an input signal is sampled during periods Cl, C2...&c. by comparing the signal with successive line-scan signals where each line-scan determines a sampling period. The maximum and minimum values of the signal in each sampling period are stored and the difference between the values is displayed during the next period as a line extending between points representing these values. A ramp-generator 13 feeds the scanning coil 18 of c.r.t. 12 to provide a single-line rectilinear scan on the screen 16. The generator is connected to comparators 33, 34 respectively producing outputs whenever the ramp signal is less than the maximum or exceeds the minimum (stored) values of the input signal during the immediately preceding line-scan. An exclusive-OR gate 15 provides an output to an unblanking amplifier 14 whenever the outputs of the comparators are the same. Thus the trace is brightened whilst the scanning signal is between the two values. The successive bright lines are recorded on a vertically moving light-sensitive sheet 20 exposed to a fibre-optic block 19 aligned on the screen 16 with the spot scan. The input signal is gated during successive scans alternately to channels A, B by gates 25A, 25B under the control of a flip-flop 39. The flip-flop is triggered by pulses CL emitted by the generator 13 during each fly-back period. Each channel comprises a detection and storage circuit respectively 27A, 27B for maximum and minimum values of the signal, and pairs of gates respectively 29A, 30A and 29B, 30B for gating the stored values alternately to comparators 33, 34. The storage circuits and gates are controlled by OR gates RA, RB, WA, WB such that signals are detected and stored in one channel whilst they are being read out of the other.

Filed: 1945-03-14
Abstract: <PICT:0589000/III/1> A machine for applying coating material to adjacent angularly related surfaces upon a workpiece comprises work-engaging rolls arranged in end-to-end relation and adapted to engage at their peripheries, different points of a workpiece, means for urging one of the rolls endwise against one of the angularly related surfaces on the workpiece, and means for supplying coating material to that angularly related surface of the work engaged by the last mentioned roll.  In the Figures the apparatus comprises a frame 24 on which is pivoted an arm 28 to which is attached by screws 30 a carrier plate 32 having dovetailed ways 34 in which is adjustably supported the arm 38 acting as a support for a slidable head 40, and also carrying rolls 16 and 18.  Arm 26 and all it supports is urged downwards by spring 42 working against plug 44 fixedly attached to frame 24.  When the machine is idle the abutment 50 acting against lug 48 holds arm 26 and all it supports out of contact with the lower roller 14, Fig. 3. Depression of a treadle arm 56 lowers the abutment 50 and allows spring 42 to operate.  Feed roll 16, applying roll 18 and supporting roll 14 are operated through driving shaft 64 and cogs 60, 62, 186 and 194.  The depression of the treadle arm 56 also operates arm 90 which, working against spring 104 on arm 98, draws sliding head 40 forwards towards plate 32, by means of stud 94 attached to head 40 and over which passes the end 96 of arm 98. and so causes applying roll 18 to move towards roll 16.  This movement of the top portion of the apparatus forces angle piece 120 attached to 32 and 38 against spring 160 and so against collar 162, which causes forked arm 168 to operate on crank 170 forked at 172 and so to lift needle valve 134 controlling the supply of coating material to applying roll 18.  The applying roll 18 is <PICT:0589000/III/2> <PICT:0589000/III/3> grooved and the end surface 22 of this roll has radial grooves 23 communicating with longitudinal grooves in the periphery of the roll.

Title: Improvements in the manufacture of preparation of granular carbon
IPC: C01B31/00
Filed: 1926-03-08
Abstract: 272,279. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). March 8, 1926. Controlling consuming devices.-In the manufacture of granular carbon suitable for telephone transmitters, preliminary heating of carbonaceous material is effected in an electric resistance furnace, of which the temperature is gradually over a period of about 14 hours to a maximum of about 800‹-1100‹ C. The rise of temperature may be automatically controlled by the apparatus shown in Fig. 2 in which two furnaces 12, 13, in series respectively with adjustable resistances 14, 15, are connected in parallel across a source of power A, B. The settings of the resistances 14, 15 determine the maximum temperatures to which the furnaces 12, 13 will be raised. The rate at which the temperature is raised is regulated by a rheostat 16 driven by a motor 17. After the furnaces have reached their maximum temperature a time switch 19 opens the circuit by means of the switch 20. After each heating period, the current through the rheostat 16 is reversed bv a switch 21. The final heat treatment is effected continuously in a rotating inclined tube electric furnace the temperature of which is maintained constant, at from 50‹ to 350‹ C. above the highest temperature attained in the pre-roast furnace, for about 1 hour by means of the regulator shown in Fig. 5. The galvanometer G, arranged as in a wheatstone: bridge, has two contacts by means of which a polarized relay Pr is controlled, which in turn controls a relay M regulating the rheostat R<1> by means of which the current through the furnace F is controlled. To prevent sticking of the galvanometer arm, periodic impulses are sent through the galvanometer by means of a rotating switch S.

Title: Improvements in or relating to detergent compositions
IPC: C11D3/384
Filed: 1953-03-11
Abstract: Shaped detergent compositions are made from dispersions of organic soapless detergents in a gelatine gel.  Suitably, gelatine is dissolved in a hot aqueous solution of an organic soapless detergent and the solution is poured on to a cooled plate to produce a sheet, which is then cut into pieces as required. Alternatively, the gelatinous solution may be poured into cooled moulds.  The products may be given a spongy texture by dispersing air in the solution before the latter is cooled, and they may be coated with a powder, e.g. starch, dextrine or talc, to prevent them from sticking together.  The detergents may be the alkali, ammonium or substituted ammonium, e.g. triethanolamine, salts of alkylaryl sulphonic acids, alkyl sulphuric acid esters or sulphonated fatty acid amides.  Such ionic detergents may be used in association with a less amount of a non-ionic detergent, e.g. a condensation product of ethylene oxide with an alkylphenol.  The compositions may also contain carboxymethyl cellulose and inorganic salts such as sulphates, chlorides and ortho-, meta-, pyro- or polyphosphates, and a small proportion of a hygroscopic substance, e.g. glycerol, may also be included, to prevent the products from drying-out.  Examples are given.
