Title: Rear Suspension Systems for Road Vehicles.
Inventor: PARKES ERIC BERNARD
IPC: B60G17/015
Filed: 1966-05-20
Abstract: 1,180,916. Vehicle suspension. JOSEPH LUCAS (INDUSTRIES) Ltd. 5 May, 1967 [20 May, 1966], No. 22547/66. Heading B7D. A screw jack is interposed between each suspension unit and the vehicle frame of a vehicle rear wheel suspension, each jack 14 being operated by its own electric motor for raising and lowering the vehicle height relatively to the wheels, the motors being operated simultaneously and limit switches 15 and 16 being provided at the limits of the screw jack travel. The motor operating circuit includes manuallyoperated switches 21, 21a operated simultaneously for energizing the motors 11, 11a, and each jack 14 is associated with limit switches 15, 16, comprising contact-making devices 151, 15<SP>11</SP> and 16<SP>1</SP>, 16<SP>11</SP>, respectively, for motor 11 and 15<SP>1a</SP>, 15<SP>11</SP>a, 16<SP>1a</SP>, 16<SP>11</SP>a for motor 11a. As shown, the switches are in the position where the screw jacks are in the lower position. To raise the jacks, switch 21 is moved to its opposite position whereby current from line 13 energizes a relay 23 to operate a contact 23<SP>1</SP> to energize the motor in a direction to extend the jack, switch 21a being moved simultaneously with similar operating conditions for motor 11a. As the jack commences its movement, contact 15<SP>1</SP> closes and 15<SP>11</SP> opens, this having no influence upon the motor circuit as there is now a current flow through a resistor 24 maintaining contact 23<SP>1</SP> closed. At the upper limit of travel, switch 16 is operated, whereby contact 16<SP>1</SP> opens so that contact 23<SP>1</SP> resumes its original position and contact 16<SP>11</SP> closes. By moving switch 21 to its shown position, relay 22 is energized to operate contact 22<SP>1</SP> and operate the motor in the reverse direction.
Patent GB-441782-A (GB)
Title: A process for the manufacture of bitumen dispersions
IPC: C08L95/00
Filed: 1934-08-02
Abstract: Bituminous emulsions which have been made with the aid of a neutral or alkaline aqueous solution of an alkali soap of solid rosin are stabilized by means of a calcium or like insoluble soap of solid rosin.  The calcium soap may be obtained by heating lime with rosin, if desired in presence of a flux such as excess rosin or fuel oil, or it may be obtained by the action of a calcium salt on a solution of alkali rosin soap.  It may be added to the bitumen before or after emulsification and in the latter case may be obtained by decomposing the alkali rosin soap used as emulsifying agent, or both these methods may be employed in sequence.  A wood rosin is preferred for both the soluble and insoluble soaps.  According to examples: (1) 100 parts of rosin and 3,75 parts of hydrated lime are heated at 140 DEG C. until homogeneous and dissolved in an equal weight of fuel oil.  4 Parts of this solution are added to 100 parts of bitumen and the mixture is dispersed in N /20 potassium rosinate solution to give 57 per cent bitumen content; (2) the product of (1) is treated with sufficient 10 per cent calcium chloride solution to decompose the potassium rosinate.

Patent GB-1197425-A (GB)
Title: Windshield Wiper Control System
IPC: B60R16/00
Filed: 1969-05-05
Abstract: 1,197,425. Windscreen wipers. FORD MOTOR CO. Ltd., 5 May, 1969 [6 June, 1968], No. 22734/69. Heading A4F. [Also in Divisions H1 and H2] In a windshield wiper control system, a wipe cycle is initiated by actuating switch 11 to close contacts 3, 4, and open contacts 1, 2. Motor 17 then causes movement of the wiper system from a park position to the normal wipe cycle and constant repetition of the cycle. A power signal is maintained on circuit B during movement from the park position, and, up to the start of the wipe cycle, an earth signal is applied to circuit C whilst circuit A is changed to a power signal. When a wipe cycle commences, the power signal remains on circuit B, circuit C receives a power signal, whilst circuit A has an earth signal over the major portion of each wipe cycle. At the end of each cycle, the signals on circuits A, C, are interchanged. Contacts 1, 2, are closed and contacts 3, 4, are opened for return to a park position, the motor circuit being completed through lead 24. The motor is reversed by the interchange of signals on circuits A, C, and the motor is braked when both circuits receive earth signals. A switch 23 has terminals 22, 42, 43, associated with the circuits B, A, C, respectively as well as an earth contact 48. Strips 51, 52, are adapted to interconnect contacts 67, 48, respectively with contacts 46, 44. A pivotable element 53 associated with cam 54 enable the various signals to be applied to the circuits A, C, the cam being driven in synchronism with the motor. Initially, pivotable cam follower 62 engages stop surface 67 whereby surface 57 does not actuate strip 51 whilst surface 58 actuates strip 52 to apply an earth signal to circuit A. Rotation of the motor causes the follower 62 to move along track 68 to ramp 69 whereby neither of the strips 51, 52, are deflected. Further rotation of the cam causes the follower 62 to move up the ramp 69 and around the surface 71 so that strips 51, 52, are both pivoted to apply an earth signal to circuit A and a power signal to circuit C. The interchange of signals on circuits A, C, is effected when the cam follower reaches step 72. Thereafter, the follower moves up the ramp 69. If the switch 11 has been moved to close contacts 1, 2, the interchange of signals causes the motor to reverse and the follower 62 moves along track 68 until it engages stops surface 67. The length of the track 68 determines the distance through which the wiper blades are moved from the wipe cycle to the parked position.

Title: Electrolytic machining process and apparatus
IPC: B23H3/00
Filed: 1963-06-07
Abstract: In electrolytically machining a metallic workpiece, the fluid fed to the work gap under pressure comprises a machining electrolyte admixed with a gas.  Typically the fluid pressure is 3.5 kg/sq. cm and the gas admixture comprises at least 50% by volume of the electrolyte calculated at atmospheric pressure and may be present in a ratio of 100:1 by volume, e.g. by atomizing the electrolyte into the gas stream.  Any gas not noxious to the operator may be used, including air, but advantageously a non-explosive gas such as carbon dioxide or nitrogen is employed, particularly if a transparent shroud is fixed around the workpiece and the cathode through which the gas-electrolyte mixture is supplied.  The escaping electrolyte is collected in a tray from which it may be withdrawn, e.g. by a pump, for cyclic operation. Examples are given of suitable electrolytes for machining low carbon steels (NaCl), high carbon steels, iron, chromium, tungsten-and cobalt steels (NaCl-NaNO3) aluminium, cobalt-chromium-tungsten alloys containing a minor percentage of iron, and hard alloys of tungsten carbide and cobalt (NaCl-NaOH or KCl-KOH), and tungsten carbide, titanium carbide and cobalt (NaCl-NaNO3 or KCl-KNO3).  The cathode may be of brass.

Title: Improvements in and relating to methods of and apparatus for granulating slag
IPC: B02C23/18
Filed: 1923-09-10
Abstract: 204,318. Gelsenkirchener - Bergwerks- Akt.-Ges. Abteilung Schalke, and Opderbeck, E. Sept. 25, 1922, [Convention date]. Granulating or atomizing. - In granulating blast furnace and other fluid slag in centrifugal mills with the addition of water, the, whole of the cooling water is added in quantities limited by the amount which the heat supplied by the slag can convert into steam. In the centrifugal mill shown, the slag enters by an inlet a and falls on a high-speed rotary plate c provided with angular beating-members d by which the slag is thrown against a ring e and pulverized. The water is added through an inlet b and cools the slag, the steam formed serving partially to open the slag. The pulverized material passes through a funnel f on to a second rotary plate g, which is constructed as a fan and throws the material against a ring h whence it falls into a funnel i for removal. The fan acts to carry away steam and air with the material which leaves the mill in a dry state.

Title: An improved weatherboard for doors
IPC: E06B7/20
Filed: 1956-07-24
Abstract: 862,958. Draught excluders. FEARN, H. July 2, 1957 [July, 24, 1956], No. 22804/56. Class 20(3) A sheet metal draught excluding strip 2 hinged at 3, 4 to the underside of an attachment strip 5 secured, adjacent to the lower edge, to the outer face of a door D has, adjacent the lock side of the door, an angular extension plate 6a which, when the door is closed, engages behind a jamb j and rotates the strip 2 downward in an operative position where it engages the outer side of a threshold bar 1. A leaf spring 7, secured to the upper edge of the strip 2, has a loop which co-operates, with a two-way group action, with the outer edge of the attachment strip 5 to urge it either into its raised, or lowered, position. The edge of the strip 5 which co-operates with the spring 7 may be pressed out at 5c. When the door is opened the threshold bar 1 lifts the strip against the action of the spring 7 until the latter rides over the edge of the strip 5 which is then urged into its raised position. The spring 7 may be replaced by a piston and cylinder activator employing fluid and a spring, or by a leaf spring which presses the strip 2 against the threshold bar 1 when the door is closed, a catch maintaining the strip elevated after having been swung into the elevated position. The cross bar, which may be an inverted channel member of metal providing a true straight surface for the strip to bear against when lowered, can be fitted in position by spreading a roughly formed cross bar, e.g. of cement, and pressing the channel member on to it while the cement is soft. Where a room carpet is of sufficiently solid nature the adjacent edge of the carpet may be employed to elevate the strip 2 instead of the threshold bar 1.

Title: Process for copying on positive diazotype layers
IPC: G03C5/20
Filed: 1936-08-20
Abstract: 464,613. Photographic diazotype processes. NAAMLOOZE VENNOOTSCHAP CHEMISCHE FABRIEK L. VAN DER GRINTEN. Aug. 20, 1936, No. 22986. Convention date, Aug. 23, 1935. [Class 98 (ii)] In producing positive copies on layers containing diazo compounds having amino groups in the nucleus, the copying light comprises substantially rays falling in the ranges of low absorbtion of the diazo compound, with substantial exclusion of rays falling in the ranges of high absorbtion. The process is specially suitable for reflex copying and the making of half-tone copies. Sources of light emitting the desired combination of rays may be used, if necessary with the interposition of filters. Examples are given of the ranges of suitable and unsuitable rays for a number of diazo compounds, chiefly those having a tertiary amino group in para position to the diazo group, and of sources of radiation and filters for the process. Zinc, cadmium, and mercury vapour lamps of glass having a high ultraviolet light transmission are instanced for use with or without a filter. As filters, quinine sulphate, an aqueous solution of the diazo compound in the layer, or a solution of potassium chromate in caustic potash may be used. The copying may be effected in two stages, during the second of which the filter is removed so that the undesirable rays are allowed to act. Specifications 383,791 and 425,126 are referred to.
