Title: Change-speed mechanism, chiefly for motor-vehicles
IPC: F16H3/091
Filed: 1932-12-15
Abstract: 405,095. Change-speed gearing. ALVIS CAR & ENGINEERING CO., Ltd., CLARKE, G. T. SMITH-, and DUNN, W. M., Alvis Works, Holyhead Road, Coventry. Dec. 15, 1932, No. 35544. [Class 80 (ii).] Relates to means for effecting reversed driving in change-speed gearing suitable for vehicles of the type comprising for the lowest forward speed a pair of constant-mesh gears such as 26, 27 connecting a lay shaft 12 to a driven shaft 16, one of these gears being fast on, and the other loose and clutchable to, its shaft. The reversed drive is brought in by sliding an idler into mesh first with a gear fast on the lay shaft and then with a gear fast on the driven shaft. The invention is described as incorporated in a four-speed gearing with synchromesh devices on all speeds described in Specification 405,200. The fast gear 26 of the first-speed pair is on the lay shaft and an idler 13 for reversing is meshed fully with the gear 26 before it moves further into mesh also with another gear 29 fast on the driven shaft 16.

Title: Programme switch unit
IPC: H01H43/10
Filed: 1972-07-31
Abstract: 1359434 Time switches; speed-responsive switches W HOLZER & CO KG 31 July 1972 [31 July 1971] 35701/72 Heading H1N A programming switch unit, for washing- machines, for example, having a main programme cam 32 driven by a motor 15 and means for rapid traverse of the cam 32, either manually or by a motor 16, is provided with a blocking switch device arranged to inhibit operation of items controlled by cam 32 during such rapid traverse, including a clutch device having a first rotatable member 11 driven from the cam 32 and a second rotatable member 7 driven from motor 15 and means arranged to operate the blocking switch 1, 2, 3 when said first member is advanced more than a predetermined amount relative to said second member. As shown, the motor 15 steadily drives a sub-interval cam 28 and the member 7, while also stepping cam 32 via a drive mechanism, not shown. Member 11 is thus also driven step by step but in general synchronism with member 7. Members 7 and 11 are loosely journalled on a shaft 6 having axial play and integral with a collar 8 which is rotationally coupled to member 7 so as to allow relative axial movement. A spring 36 urges collar 8 towards member 11 but displacement is normally prevented by interposed balls 10 riding on cam tracks 37 of member 8. An intermediate member 9 forms a cage for balls 10 and has noses 13 for co-operation with, but normally not engaging, recesses 14 in member 11. Member 9 also has dogs 9<SP>1</SP> (Fig. 3b) co-operating with lost motion with dogs 81 and 8<SP>11</SP> and a cam track 38 on collar 8. When cam 32 is rapidly advanced, manually or by motor 16, the relative movement of member 11 with respect to member 7 (and hence collar 8) causes balls 10 to move down cam tracks 37 allowing member 9 to be urged into positive engagement with member 11 and hence to be accelerated thereby. This takes up the play between dogs 9<SP>1</SP> and 8<SP>1</SP>, allowing collar 8 to move axially upwards and pivot contact member 3, against action of a spring 5, to open-circuit contacts 1 and 2 which isolate the supply from certain items controlled by cam 32. Meanwhile balls 10 have moved further on cam tracks 37 and have been lifted to disengage 9 from 11 whereby no superfluous load is placed on the rapid advance motor 16. On cessation of rapid traverse member 11 is temporarily stationary while member 7 slowly advances and hence reverse movement of the dogs 9<SP>1</SP> and 8<SP>1</SP> occurs, restoring shaft 6 axially and closing contacts 2 and 3.

Patent GB-775357-A (GB)
Title: Improvements in or relating to the production of condensation products of isobutylene and formaldehyde
Filed: 1953-12-29
Abstract: Condensation products, believed to comprise compounds of the general formula: <FORM:0775357/IV(b)/1> where R1 is a mono- or di-isobutylene radical and n is an integer in the range 1 to 5 are prepared by reacting non-catalytically isobutene with formaldehyde or a polymer thereof at a temperature above 120 DEG  C. and under a superatmospheric pressure at least equal to the autogenous pressure of the charge that would be developed in a sealed reactor at the reaction temperature and thereafter subjecting at least part of the product to distillation with recovery of a fraction having an initial B.P. above about 170 DEG  C. and a final B.P. below about 300 DEG  C. (both temperatures being corrected to atmospheric pressure).  The reaction pressure should preferably be sufficient to maintain the reactants substantially in the liquid phase and may be up to 100 or more atmospheres.  The subsequent distillation is preferably effected under reduced pressure.  The resulting fraction or part thereof may be hydrogenated whereby the unsaturated components are converted to the corresponding mono- or di-isobutyl derivatives, suitably using Raney nickel or a supported nickel catalyst at below 150 DEG  C.  All or part of the saturated products may be esterified with one or more carboxylic acids such as lauric, stearic, palmitic, succinic, azelaic and sebacic acids and aromatic dicarboxylic acids, which may contain halogens or alkyl substituents, e.g. phthalic acids and phenylene diacetic acid, or with the anhydride or alkyl ester of the acid.  The esterified products may be used as hydraulic fluids or in synthetic lubricants or plasticizers.  In an example 2 mols. each of isobutene and paraformaldehyde are heated in a sealed autoclave at 200-210 DEG C. for 21 hours and the product is distilled to recover unchanged isobutene, a fraction mainly of isobutenyl carbinol and the desired fraction B.R. 60-104 DEG  C. at 0.5 mm. which comprises mainly the alcohol: CH2 = C(CH3).CH2CH2-O-CH2OH A table is given for correction of boiling temperatures.

Title: Improvements in or relating to cathode ray tubes
IPC: H04N3/26
Filed: 1946-12-12
Abstract: 623,072. Cathode-ray tubes. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Dec. 12, 1946, Nos. 36723 and 36724. Convention dates, Nov. 24, 1943. [Class 39 (i)] [Also in Group XL (c)] In a cathode-ray tube with a rotating radial scan, a voltage derived from the scanning voltage is fed to the control electrode to increase the intensity of the beam progressively with its radial deflection from the centre. It is thus possible to compensate for the overlapping of the scans at the centre which otherwise makes the screen brighter at the centre than at the circumference. In Fig. 1, the valves 12, 13 form a multivibrator, the output from which is fed through cathode follower 11 to the rotating deflecting coil 9. Part of the sawtoothed waveform from 11 is fed to the grid of the variable gain amplifier 29 whose output is connected to the grid of the cathode-ray tube; thus the gain of the amplifier is increased with the deflection of the beam. Input signals (e.g. radar signals) can be connected at 25 to the grid of the amplifier 29. In a modification, Fig. 3 (not shown), the amplifier 29 is omitted and both the input signals and the output from 11 are fed direct to the grid of the cathoderay tube.
