Title: Method of and apparatus for shaping sheet material
IPC: C03B23/031
Filed: 1958-02-18
Abstract: 880,155. Shaping glass sheets. COMPAGNIE DE SAINT-GOBAIN. Feb. 18, 1958 [Feb. 18, 1957], No. 5315/58. Class 56. In shaping glass or like sheet material, as for "wrap around" windscreens, the sheet is rendered plastic, disposed adjacent a rigid mould of desired shape and pressure applied to the periphery only of the sheet to shape the sheet, the pressure being applied first to the portions of the periphery at the central zone and then to the remaining portions of the periphery progressively outwards to each end of the sheet. A convex mould 1 of sheet steel has a central large radius cylindrical surface 2, conical intermediate surfaces 3 and terminal plane surfaces 4, the surfaces being covered with a spun glass fabric to prevent sticking. The mould 1 has adjustable stops 5 to engage a deformable mould 1<SP>1</SP> and is formed with recesses 6 to receive the glass sheet suspension means. The deformable mould 1<SP>1</SP> is formed by rigid strips 7 to 12 of metal covered by spun glass fabric, the strips 7, 8, 9, with gaps 13 corresponding to the recesses 6 for the glass suspension means, the end strips 11 and a single lower central strip 12 (not shown) being straight in the plane of the figures and the strips 10 corresponding to the surfaces 3 being normal thereto. The strips 7-12 are secured to supporting members 14, 15, 16 by means of adjustable rods 17, the members 14, 15, 16 being pivoted together at 18<SP>1</SP>-21<SP>1</SP> along axes XX<SP>1</SP> and YY<SP>1</SP>. The strip 10 may be made of rubber, backed by the steel strip and enclosed in spun glass fabric, so as to be more easily bent by adjustment of rods 17 to the required shape. As shown in Fig. 1, the mould 1<SP>1</SP> is carried by a shaft 28 secured to members 14 for movement towards the mould 1 to press the centre section and pressure is then applied to the end of members 16 by hydraulic units 33 which urge the sections 10, 11 towards the mould 1, the members 15, 16 being joined by springs 27 powerful enough so that the sections 10 engage the section 3 before the end section 11 engages the section 4. Counterweights 29 (not shown) passing round pulleys 31, 32 and the springs 27 return the mould 1<SP>1</SP> to its opened out position for receiving the glass sheet 22. As shown in Fig. 4, the sections 10, 11 are moved by rack and pinion units 34, 35 and 34<SP>1</SP> 35<SP>1</SP>, the pinions 34, 34<SP>1</SP> being secured to shafts 36, 38 which constitute the pivots 19<SP>1</SP>, 18<SP>1</SP>, the shafts being interconnected by a member 37 pinned to shaft 36 and rotatable on shaft 38. A similar member 39 is pinned to shaft 40 and rotatable on shaft 41 which constitute pivots 21<SP>1</SP>, 20<SP>1</SP>, the members 37, 39 being braced by a stirrup 42. In a further embodiment, the strips are supported by box-like members pivoted together and connected by bellows, each pair -interconnected by a pipe with valves so that the intermediate sections move before the end sections.

Title: Improvements relating to winding up mechanism for clocks
IPC: G04B5/24
Filed: 1928-02-22
Abstract: 285,839. Meier, K. H., and Huessy, W. Feb. 22, 1927, [Convention date]. Winding-apparatus; overwinding, preventing.- A clock or similar spring is kept substantially fully wound up by means which include a continuously rotating member and a. spring which absorbs the excess power when the main-spring is fully wound. A lever g under the action of a spring l carries a pawl k adapted to drive a ratchet wheel n connected to one end of the mainspring. This lever g is connected by a rod or wire c to a spring e anchored at f. A connecting rod a is attached to the member c and is reciprocated by a constantly rotating crank disc b; for example, in an automobile this disc is rotated by means equivalent to the speedometer driver. At first the point d acts as a relatively fixed point and the rod a vibrates the member c and oscillates the pawl k backwards and forwards to wind up the spring. When the latter becomes fully wound, however, its resistance is greater than the spring e so that lever g remains still while the members a and c merely idly extend the spring e. Specification 257,941 is referred to.

Abstract: 1,149,231. Transistor switching circuits. WALLACETOWN ENG. CO. Ltd. 10 April, 1966, No. 5695/65. Heading H3T. [Also in Division H2] A protective arrangement comprises a transistor T1 which, in the event of fault conditions, is rendered conductive by the bias provided by a fault detecting device SW in addition to that provided by a stabilized D.C. source. When transistor T1 conducts, a second transistor T2 is biased to conduction and through resistors R6, RV2 and a diode D3 provides a positive feed-back to the transistor T1 which increases the conductivity of the transistor T1 and consequently that of the transistor T2 so that a latching relay RL1 is operated to effect the opening of a main contactor in the protected circuit. A resistor R7 and a capacitor C3 provide a time delay to prevent incorrect operation when the arrangement is first switched on. The fault detecting device SW may be a core-balance transformer, Fig. 1 (not shown), in which case Zener diodes Z3, Z4 are connected to limit the bias applied to the transistor T1.

Abstract: 560,595. Converting. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 14, 1943, No. 6008. Convention date, May 2.1, 1942. [Class 38 (ii)] Relates to a protective, arrangement for a converting system comprising parallel-connected vapour-electric converters A, B of the type to which ignition impulses are applied to immersion ignitor electrodes, and a.c. control voltages superposed on a d.c. bias are,applied to shield electrodes surrounding the anodes, and consists' in providing each converter with a high-speed relay 98A or 98B responsive to fault conditions in the associated converter to cut off the ignition impulses from the ignition electrode and the a.c. voltages, but not the d.c. bias, from the anode shields. In the arrangement shown, in the event of a fault such as back ignition in either converter, the ignition impulses and the a.c. control voltages are initially cut off from both converters at contacts 198 of one or other of the relays. In the case of the faulty converter, however, a reverse current relay 72A or 72B opens to remove that converter from the d.c. bus-bars 11, and in so doing it energizes through back contacts 272 and relay 93rx a resetting coil 35 for the highspeed relay of the faulty converter. Thus the ignition and control circuits for the sound unit are re-established, whilst the corresponding. circuits for the faulty unit remain interrupted at contacts 172 of the associated reverse current relay. In a modification, Fig. 2 (not shown); overload relays are associated with each converter, and resetting coils energized through a' time delay relay are provided for rectosing the high speed and overload relays of all the converters after the ignition and control circuits of the faulty unit have been interrupted at the contacts of the associated reverse current relay.

Title: Purification of crude aliphatic alcohols by distillation
IPC: B01D3/40
Filed: 1950-03-10
Abstract: <PICT:0673768/III/1> In the purification of a crude C3 to C5 aliphatic alcohol, obtained synthetically from a mono-olefin, by distillation in a column supplied at the upper part with sufficient water to increase the relative volatilities of the impurities with respect to the alcohol so that the impurities, together with some alcohol, pass out of the column as overhead vapours, while a dilute aqueous solution of the purified alcohol is withdrawn as bottoms; loss of alcohol is avoided by allowing the overhead condensate to separate into two layers, returning the aqueous layer to the upper part of the column, extracting the organic layer with water, and introducing the aqueous extract into the upper part of the column. Crude isopropanol, obtained by hydration of propylene, was fed through line 1 into 54-plate column 2 which was supplied with water at 97 DEG C. through line 3. The isopropyl ether, and substantial amounts of the acetone and propyl oil, contained in the crude isopropanol, were carried overhead and condensed; and the condensate was passed to decanter 5 where it separated in two layers.  The organic layer 6 was led via line 8 to countercurrent extractor 9 which was supplied with water through line 10.  The raffinate phase was withdrawn through line 11 and discarded; while the aqueous extract was refluxed through line 12 to column 2 together with the aqueous layer 7 from decanter 5.  It is possible to return this reflux through line 3; alternatively line 3 may be dispensed with by adding all the water required for both the extraction and the distillation, through line 10.  The concentration of water in the column was 92.5 mol per cent.  Polymer oil not taken overhead was removed from column 2 through line 26, separated from aqueous alcohol in decanter 27, and eliminated from the system; while the aqueous alcohol separated in the decanter, was returned to the column through line 30.  Bottoms containing 25 per cent isopropanol were withdrawn from column 2 through line 14, and concentrated in column 15.  The concentrated isopropanol was withdrawn from column 15 through line 16.  Residual propyl oil and acetone are withdrawn from column 15 through lines 17 and 18 respectively.  The yield of purified isopropanol in the bottoms from column 2 was 97 per cent.  The removal of odour due to sulphur-compounds in the crude is accomplished by adjusting the pH to a value in the range 6-10 before or during the extractive distillation, or before the bottoms from the extractive distillation are passed to the concentrating column.  The crude is preferably heated under pressure for about 2 hours at 100 to 125 DEG C with sufficient caustic soda to bring the pH to 9-10.  The treated crude is then passed through a reducing valve into the extractive distillation column. Other bases such as potassium hydroxide, sodium or potassium carbonate, an alkaline earth hydroxide, a basic salt, ammonia, a primary amine, or an organic ammonia base, may be used to adjust the pH in place of caustic soda.
