A take-up device for a tape record carrier, e.g. a perforated or magnetic tape, comprises a flat case 2 open on one side, a drivable plate 20, for receiving a take-up spool 85, rotatably mounted on the bottom surface of the case and a hinged flap 65 partially closing the open side of the case and incorporating a tape guiding arrangement. The plate 20 is formed with a depending rim 21 which is frictionally engaged by a drive roller 39 mounted on a pivoted two-arm member 41 and driven via pulley 38 by a motor 52. The roller is urged into contact with the rim by the action of spring 43. Turned-up portions 34 on the periphery of the plate locate and drive the take-up spool by engaging lugs 87 on the outer rim of the spool. The flap 65 which is loaded by spring 89 is hinged to a pin 77 which is supported at one end only on a lug 80 extending outwardly from a lower corner of the open side of the case. The tape is fed in normal to the upper face of the case and is guided via edge 73, through an oblique slot in the face of the flap, which turns the tape through 90 degrees and via a guide roller mounted on the pin 77 to the take-up spool. The motor is controlled by switch 53 which is operated from the open side of the case via levers 56, 58.

Patent GB-574460-A (GB)
Title: Improvements in and relating to the extraction of useful products from heavy petroleum residua
IPC: C08F10/00
Filed: 1943-09-25
Abstract: Resinous material is extracted from cracked petroleum residues by means of a butyl alcohol.  The butyl alcohol may be either normal, iso, secondary, tertiary, or mixtures of two or more, and may contain water.  The cracked residua are treated with petroleum ether, the insoluble matter "P" separated; the petroleum ether removed from the solution, the solids dissolved in butyl alcohol and allowed to stand when two layers are formed.  Removal of the butyl alcohol gives a resin "C" from the upper layer and a resin "B" from the lower layer. Alternatively, a small quantity of an acid or acid salt (forming acetic, hydrochloric, sulphuric, sulphurous and phosphoric acids are specified) may be added to the petroleum ether solution to give a resinous precipitate and the solution which is then treated as above. Resins "B" and "C" can be further purified by dissolving in a solvent, e.g. petroleum ether, and then treating with furfural. Resin "C" can also be extracted with one or more alcohols lower than butyl alcohol, i.e. propyl, ethyl and methyl alcohols.  The insoluble matter "P" may be heated with aromatic solvent naphtha giving a solution of a resin "A" which is recovered by removal of solvent and a carbonaceous coke-like substance of use as a pigment. Specifications 566,281, 566,282, [both in Group III], 567,420, 573,240 and 573,870 are referred to.

Title: Improvements in or relating to telephone systems
IPC: H04M15/08
Filed: 1923-06-19
Abstract: 221,869. Western Electric Co., Ltd., (Deakin, G.). June 19, 1923. Semi-automatic exchange systems.-In the case of a call necessitating the service of an operator, the number of the calling line may be checked by the application of a distinctive tone to the incoming end of the line either by setting up an independent connection thereto over automatic switches, the source of tone in this case being associated with a switch preceding the final switch, or by the help of a switching operator. First arrangement, Fig. 1. The operator throws the check dialling key CDK and sets up a connection to the calling line over switches ICGS, 2CGS, 3CGS, CFS, a source of check tone CT being associated with the last group selector 3CGS, so that the connector CFS may be of the usual type. Relays R1, CTR energize over the checking circuit, lighting a lamp L, and connecting check tone through relay RR to the test wire of the calling line to give a signal to the operator when the check tone key CTK is thrown. Relay RR energizes and removes a short circuit from the high resistance winding of relay CTR, so that relay R1 releases and extinguishes the lamp L to indicate that check tone has been applied. Second arrangement, Fig. 2. A source of check tone CT is connected to the tip of a check plug CP of a switching operator located before a multiple jack J of the calling line. The switching operator is called over an order wire CC by throwing of the checking key CTK, and is given the number of calling line. On plugging into the jack J, the operator receives a check signal over the test wire, the key CTK being restored.

Abstract: 616,180. Directing nozzles. DANIELS, A. W., and B.V.C. INDUSTRIAL CONSTRUCTIONS, Ltd. May 27, 1946, No. 16044. [Class 47 (ii)] [Also in Group XXX] A sluicing jet assembly for the ashpit of a furnace includes a jet housing 34, Fig. 1, formed with an internal conduit 35, one end of which is provided with a nozzle 39 and the other end of which is fixed to a pipe 64 pivotally connected to and communicating with a high pressure liquid supply conduit 65, means being provided for moving the jet assembly into the operative or inoperative position as required. In Fig. 1, rotation of handle 48 forces nut 47 along screw 49 and thereby rotates levers 46 and 42 around shaft 43 to which both are fixed. Lever 42 moves link 66 and so swings housing 34 around the pivot 65 and above the level of the floor 10 of the ashpit into the operative position. The water supply to pipe 65 is switched on by hand at this moment to sluice the ash in the ashpit. In Fig. 4, link 66 is connected to piston 67 of hydraulic jack 68 so that when the water is switched on through both pipes 69 and 64 the jet housing automatically elevates itself and squirts water. When the water is cut off, the jet ceases and lowers itself under its own weight or under the action of return springs or of a counterweight. Specification 614,250, [Group XXX], is referred to.

Title: Apparatus for visually indicating or recording numerical values of constituents of fluids under analysis
IPC: G01N21/27
Filed: 1958-05-21
Abstract: 834,633. Photo-electric fluid analysis. TECHNICON INTERNATIONAL Ltd. May 21, 1958 [June 7, 1957], No. 16313/58. Class 40 (3). In apparatus for obtaining a quantitative indication of the concentration of a substance in a liquid the voltage produced in a photo-cell by the light transmitted through the cell containing the liquid under test is compared with that produced by light transmitted through a standard cell in a self-balancing potentiometer circuit arranged to give a linear relationship between indication and substance concentration. Light from the source 12 transmitted through the flow or test cell 38, Fig. 1, is converted to a voltage across potentiometer 46 by the photo-cell 40. Similarly, photo-cell 30 produces a voltage across potentiometer 44 from the light through the standard cell 28. The voltage between potentiometer taps 68 and 72 is applied via the converter stage 54 and amplifier 58 to the winding 60 of the two-phase motor 62 which drives the tap 68 on potentiometer 44 to balance the system. The voltage across potentiometer 46 bears a logarithimic relationship to the substance concentration, by shunting the slide wire of potentiometer 44 by the resistors 78 a logarithmic law is obtained between the voltage at tap 68 and its position along the slide wire, hence the position of the tap repeated by the pointer 74, on scale 76 is linearly related to substance concentration. A second self-balancing potentiometer circuit is driven by the voltage between tap 88 of potentiometer 86 (mechanically positioned by shaft 70 to the position of the tap 68) and tap 96 on potentiometer 90 which is applied via the converter and amplifier 94 to the two-phase motor 100. This drives the counter 114 to a figure indicative of the concentration. This figure can be printed by the unit 122 to provide a record of concentrations in a series of liquids. Circuit 124 (Fig. 2, not shown), ensures that the figure is not printed until each reading of concentration has reached a maximum value.
