Title: Improvements relating to motor vehicles with pneumatic suspension
IPC: B60S9/10
Filed: 1959-02-25
Abstract: 849,769. Road-vehicle pneumatic suspension springs. DAIMLER-BENZ A.G. Feb. 25, 1959 [Feb. 26, 1958], No. 6566/59. Class 108(2). Suction may be applied to a road-vehicle pneumatic suspension spring 3 in order that an associated road wheel 2 may be lifted for tyre repair etc. The springs 3 are normally supplied with compressed air from a compressor 4 and reservoir 5 via a conduit 8, valve 7, and conduits' 9, 10. Conduits 12, in respect of each of the four road wheels, lead to a control device 13. The latter is connected to a vessel 15 through which air passes from atmosphere (via a valve 16) to the compressor, under normal functioning of the suspension system. When a wheel is to be raised the device 13 is operated to connect the conduit 12 concerned with the vessel 15 and the valves 7 and 16 are closed. Operation of the device 13 also puts the compressor 4 into operation. A support 20 may be articulated to the vehicle body adjacent each wheel. This may be brought into the position shown by operation of the device 13. The support 20 may have a stop (not shown) which (in the supporting position) limits movement of the wheel 19 towards the body. The same conduits may be used for charging the springs as are used for evacuating them. Provision may be made for temporarily putting a spring into communication with the atmosphere before evacuation commences. The engine inlet manifold may supply the suction required.

Title: Improvements in or relating to automatic alarm systems
IPC: H04M11/04
Filed: 1945-03-15
Abstract: 589,160. Automatic exchange systems. PICKING. A. S. H., and ROONEY, I. H. March 15, 1945, No. 6590. [Class 40 (iv)] In an automatic alarm system of the kind used with a dial telephone for dialling a predetermined number, e.g. a police or fire station, and sending a warning signal to the called party, a rotating switch device is set in operation by an alarm signal (from a source not shown) and controls a solenoid 16 which when energized causes a member 18 to engage a finger hole in the dial 23, the switch then rotating it to carry out dialling operations. The lever 32, normally under the control of abutment 31 on the carriage 30, engages the switch-hook 26 of the telephone 24. An initiating alarm starts the electric motor 7 which rotates the shaft 6 ; the member 41 rides on a snail cam and reciprocates vertically, thus stepping the carriage 30 to the left. The spring 60 then swings the lever 32 to operate the switch 26. The wiper 46 is brought into contact with the discs 47 in turn, each of which has a conducting segment, and the solenoid 16 is energized during the period of contact of this segment with the wiper 46 to couple the shaft 6 to the dial. These periods are such that each disc control the dialling of a predetermined digit, provision being made for up to seven digits. On completion of the dialling, the wiper steps on to discs 52 which operate a sound producer (Fig. 2, not shown), such as a bell or buzzer disposed near the microphone, to signal to the called party. Alternatively, an audible message may be given phonographically. The apparatus is then reset to the rest position and the call is repeated until the motor is switched off. The Provisional Specification describes means for stopping the apparatus after completion of one call, and also for moving the lever 32, independently of the shaft 6, by electromagnetic means controlled by the alarm.

Filed: 1963-02-20
Abstract: 1,008,376. Punching. CONTRONICS Ltd. Feb. 19, 1964 [Feb. 20, 1963], No. 6785/63. Headings B3B, B3Q and B3W. [Also in Division B4] A protective means for a machine tool wherein a main electrical contactor of the drive motor is held in operative position so long as a regular intermittent flow of ejected parts is maintained and wherein if a part fails to eject on schedule so that the interval of time between the passage of ejected parts becomes irregular the failure is detected by sensing means, the circuit to the contactor is broken and the machine is stopped. Parts 4 which have been punched out of a strip 5 by a press 1 are directed by an air blast on to a microphone 7 and then fall into a hopper 8. The signals from the microphone pass to an amplifying and shaping circuit and appear on the base of a transistor which cuts off another transistor and causes a charge to appear on a capacitor. This charge causes a further transistor to conduct for a delay period which may be set by a potentiometer, and if another pulse is received within the delay period the further transistor is maintained in the conducting condition. If the next pulse is not received in time then the transistor ceases to conduct, a relay drops out and either stops the machine tool motor or disengages the clutch and applies the brake. Instead of a microphone, a micro-switch, a photo-cell or a proximity detector may be used to sense the ejected parts.

Title: Improvements relating to the preparation of compounds of titanium and zirconium
IPC: C22B3/32
Filed: 1943-05-03
Abstract: 569,054. Zirconium and titanium salts. EVERY, C. E. (Titanium Alloy Manufacturing Co.). May 3, 1943, No. 6986. [Class 1 (iii)] Salts of zirconium or titanium are prepared by adding an acqueous solution of a salt of the element to a solution of an alkali metal or ammonium carbonate, stirring, separating and washing the precipitate (a carbonate of indeterminate composition), and adding the washed precipitate to an aqueous solution of an acid having a dissociation constant greater than that of carbonic acid. Acids with which the reaction may be obtained include the following : hydrochloric, nitric, sulphuric, formic, lactic, citric, acetic, oxalic, tartaric, benzoic, salicylic, chloracetic, malic, succinic, sulphanilic, cinnamic and picric. The salts have the general formula (ZrO)nX2 or (TiO)nX2, where X is the acid radical and n its valency. In the formation of the zirconium carbonate it is preferred to adjust the mixture to pH 6-7, and in the case of titanium carbonate, to pH 7-8. When using zirconium sulphate, the solution may be neutralized before adding to the carbonate solution. In a modification, zirconium carbonate is made by dispersing zirconium hydrate in water and passing in. carbon dioxide under pressure or not, or by adding solid carbon dioxide to the suspension in a pressure bottle. Octyl alcohol may be added as an anti-frothing agent during either stage of the process. A small amount of formaldehyde, e.g. 0.01-0.1. per cent may be added to the final product or its solution to prevent mould growth. Examples describe the preparation of zirconium salts of acetic, oxalic and racemic tartaric acid, and the titanium salt of oxalic acid.

Filed: 1952-03-18
Abstract: 697,715. Polishing buffs. HALL, E. W. March 18, 1952 [July 17, 1951], No. 7026/52. Class 60. A buff section for assembly on a spindle side by side with other similar sections to form a buffing wheel comprises a relatively stiff centre 10 surrounded by an annulus of buffing material 14, one side of the section having an annular series of axially extending projections 20r differentially spaced with respect to a series 20o on the other side. When the sections are arranged with similar sides adjacent, one set of projections enters between the other as shown in Fig. to provide a wheel with a dense periphery and when unlike sides are adjacent, a wheel of lesser density is produced by the circumferential overlapping of at least some of the projections as shown in Fig. 5, the sections thus being more widely separated. The least common multiple of the numbers of projections on the two sides contains factors which have no common factor except 1, and the two numbers preferably have a common factor of three or more. Each section has a hub 10 of chipboard and annularly ridged side plates 16 of thin vulcanized fibre on which the projections may be formed by dies when the section is made under axial pressure, the buffing material 14 being pressed into the concavity of each projection to key it against relative radial and circumferential displacement. The side plates of each section may be different colours to enable them to be readily distinguished.

Abstract: Titanium chloride is extracted from Ti ores, e.g. ilmenite, by flowing an aqueous solution containing at least 32 weight per cent HCl through a loosely-packed mass of an ore at above atmospheric pressure the reaction temperature being controlled to within the range 70-100 DEG  C.  The HCl solution may be continuously circulated and additional HCl solution and ore introduced with an equivalent amount of dissolved titanium and chlorine being removed. The HCl may be heated prior to contact with the ore, e.g. to 70-90 DEG  C.  The ore may be in an unground form (410 B.S.S.) and be circulated in counter-current flow to the aqueous HCl.  There may be a series of masses of ore, the ore flowing from one mass to another with the HCl flowing counter-currently through the masses.  These masses may be supported on perforated plates one above another and the total area of perforations may decrease from the top to the bottom plate. Alternatively the reaction chamber may have conical sides to support the ore mass.  There may be a series of chambers, e.g. with HCl inlets at the bottom and ore inlets at the side and top.  The reaction temperature may be controlled by the addition of acid at a temperature below 70 DEG  C., e.g. 20-60 DEG  C. and/or by controlling the rate of flow of acid and/or by the use of a heat exchanger. The ratio of Cl : Ti in the resulting solution may be smaller or greater than 4 : 1.
