Abstract: 1504601 Disc brakes GIRLING Ltd 7 Jan 1976 [23 Jan 1975] 2916/75 Heading F2E In a disc brake with opposed hollow pistons 8, 9 working in a caliper 1 to actuate respective pad assemblies 4, 5 through thrust transmitting shims 17, each shim 17 includes a portion removed at 20 so that the thrust applied by the piston 8 (or 9) is not applied over what would otherwise be the area of contact of the shim 17 and the piston to the respective pad assembly 4 (or 5), the material previously occupying the portion 20 including a projection in the form of a tag 21 defining a stop to prevent insertion of the shim 17 into the brake when the respective pad assembly 4 (or 5) is in position, and the axial length of the shim 17 including the tag 21 is less than the thickness of the backing plate 13 of the pad assembly 4 so that the shim 17 can be removed from the brake after removal of pad assembly 4 without forcing back piston 8 in its bore. The tag is provided with parallel end edges (22) for engagement with the internal wall of the piston to support the shim 17 in the brake. This arrangement prevents the shim 17 being inserted with the pad assembly still in position, thereby preventing damage to the piston and its associated boot 15. The shim 17 is formed with apertured lugs 19 for the insertion of drag-taking or other locating pins which are also inserted through the backing plates 13 of the pad assemblies 4, 5.

Title: Process for the polymerisation of olefines or olefine-containing mixtures
IPC: C08F255/00
Filed: 1956-01-30
Abstract: A polymerization process comprises passing an olefine, e.g ethylene, or a gas mixture containing the olefine, into a volatile organic solvent containing a catalyst comprising a reducible compound of a heavy metal and an organometallic compound, and when sufficient polymer to act as catalyst carrier has been formed, withdrawing the organic solvent, preferably by distillation, and continuing polymerization while the polymer is agitated.  The organic solvent may be a normally gaseous hydrocarbon which is maintained in the liquid state by pressure, e.g. n- or iso-butane, or a liquid hydrocarbon such as n-pentane, n-hexane, cyclohexane, ethylcyclohexane, benzene, toluene, light benzine, a light petroleum distillate, or mixtures thereof. Catalysts specified are titanium tetrachloride with aluminium triethyl or mono-chloro aluminium diethyl.  The process may be carried out continuously with continuous or intermittent addition of catalyst and withdrawal of polymer, this polymer being optionally used in a further reaction.  The speed of polymerization may be controlled by returning some of the organic solvent during the first stage and/or by controlling the rate of stirring.  In Example (2) the solvent used is a benzine (boiling range 50 DEG  to 70 DEG  C.) which has been purified with sulphuric acid. The products are of low ash content.

Abstract: 1,216,562. Respiratory apparatus. MEDIZINTECHNIK LEIPZIG. VEB. 19 Jan., 1968, No. 3066/68. Heading A5T. A device for use in artificial respiration comprises a generator 4 of oscillations, the output 6 of the generator being connected in the breathing gas line 5 between a respiratory device 3 providing negative and positive pressure pulses of gas, and the outlet 1 (e.g. a tracheal catheter) to the patient. The device is able to set up oscillations in the volume of gas between the respiratory device 3 and the patient's lungs, the frequency of the osillations being greater than the respiration frequency, and the oscillations are said to accelerate the mixing of the new breathing gas with residual gas left in the lungs. The output frequency of the oscillator is said to be adjustable.

Abstract: 781,506. Agitating contents of flasks &c. VITAMINS, Ltd. Feb. 6, 1956 [Feb. 4, 1955], No. 3383/55. Class 86  Means for agitating a vessel, such as a flask 14, Fig. 1, so as to induce a swirling motion in the contents thereof, comprises a rod member 10 which is provided at its lower end with a clamp 12 for engagement with the neck of the flask and is connected at its upper end to a sleeve 7 mounted on the reduced and slightly inclined end portion 2 of a rotatable driving shaft 1. A pair of ball-bearings-6 is disposed between the shaft 2 and sleeve 7 with the inner and outer races thereof, respectively secured, to said latter parts, and rotation of the flask is prevented by a pin 8 on the sleeve 7 which is adapted to engage a slot 9 in the lower end of a casing 4 surrounding the shaft 1. The apparatus is supported by a member 5 extending from the casing 4, and, if desired, the pin and slot connection 8, 9 may be replaced by a short length of metal bellows 16, Fig. 3, extending between the casing 4 and sleeve 7. The support member 10 may be caused to trace a cylindrical surface, instead of a conical surface, by mounting the sleeve 7 on a reduced end portion 2 of the shaft 1, the axes of the shaft and its end portion being parallel and eccentric. The invention is stated to be particularly applicable to the agitation of liquids which are being heated at a reduced pressure, the reduced pressure being attained by a connection 15 between the flask 14 and a vacuum line. Several modifications are described. For example the support member 10, Fig. 5, may be non-rotatably mounted in a gimbal mounting 17 within the casing 4 which is provided with a hollow support arm 5 leading to a horizontal vacuum pipe 30; the inner end of the member 10 engages a sleeve 23 associated with an eccentric pin 22 at the lower end of the shaft 1 and the outer end terminates in a standard cone 24 to which a flask is adapted to be attached, said cone 24 being hollow and in communication with the interior of the casing 4 through an axial bore in the member 10 and an aperture 25. Fig. 6 shows a metal bellows 37 supported by arms 31, 36 carrying, respectively a socket 32 for connection to a conventional gas distillation assembly and a flask cone 36, the arm 31 extending from the casing 4 surrounding the driving shaft 1 and the arm 36 being secured to a sleeve 35 mounted on an eccentric pin 34 on said shaft.

[Class 64 (i).] A washing - boiler is fitted with one or more condensers which may be alternately or intermittently supplied with cooling medium to cause periodic pressure variations in the apparatus. The boiler comprises two chambers 5, 6, shown in the Figure, with condensers 7, 8, alternately supplied with cooling medium through a valve 9 which is driven by the cooling medium pressure. In another construction a bell, containing a condenser intermittently supplied, is immersed in a vessel open to the atmosphere. Perforated screens 13, 14 hold the articles to be washed in position so that the oscillations of the liquid caused by the pressure variations will wash them. Cocks 10, 11 are closed during operation and may put the chambers into communication with the atmosphere or an evacuating device to adjust the mean pressure of operation. The whole boiler may swing on a horizontal axis and the lid 2, which is provided with packing 12, may be at the bottom instead of the top.
