Abstract: 703,268. Partly electromagnetic switches. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Oct. 18, 1951 [Oct. 19, 1950], No. 25542/50. Class 38(5) A vibrating regulator is provided with electromagnetic bias in the form of a coil mounted on the vibrating contact arm and co-operating with a magnetic field system, whereby the current in the moving coil determines the percentage time the contacts will engage. The field system may be a permanent magnet, or may have an energizing winding carrying a variable current, the bias then being proportional to the product of the current in the two coils. The regulators are applicable e.g. to traction systems as described in Specifications 703,263, 703,264, 703,265 and 703,266, [all in Group XXXV]. As shown arm 30 carrying a contact 34 co-operating with adjustable fixed contacts 35, 36 is pivoted on a knife-edge at 14 and vibrated by a motor 26 driving a crank 24 coupled to the arm above the pivot by a spring 22 pulling against the tension of a spring 17 connected to the arm at 15, below the pivot.

Chains.-Roller or semiroller chains are made by first assembling bushedlinks and rivet-links in jigs and then connecting the bushed and rivet-links in a third jig, after which the rivets are headed in a machine. The rivet-links are made by placing rivets in a jig comprising a base 1 having an integral sidemember 3 and a hinged cooperating member 5 adapted to be clamped against the member 3 bv an eccentric locking-lever 6. The meeting faces of the members 3, 5 are grooved to receive the rivets. A link-cheek is then placed over the rivets and riveted in place. The bushed-links are similarly assembled, the side members 3, 5, Fig. 3, of the jig being undercut, and the base recessed, to accommodate the riveted link-cheek when it is inverted to receive the other link-cheek. The completed bushed-links are then assembled on the rivets of the rivet-links and placed in a jig comprising a slotted-base 1, Fig. 5, a fixed member 3 and a spring-pressed slide 11 actuated by a cam-lever 6. The remaining cheek of the rivetlink is then placed in position and the rivets headed so as to complete a chain-section comprising one rivet-link and two bushed-links.

Title: Improvements in or relating to the cooling of biological specimens in two or more stages and apparatus therefor
IPC: G05D23/24
Filed: 1959-07-29
Abstract: 911,161. Cooling bone marrow &c. TROTMAN, R. E., and PEGG, D. E. July 27, 1960 [July 29, 1959], No. 25962/59. Class 49. Apparatus for cooling biological samples in two or more stages comprises a partially insulated cooling vessel and a cooling bath containing a suitable refrigerant, together with means to alter the cooling rate when predetermined temperatures have been reached. The cooling vessel may be a metal beaker MS with a lagged base L. The cooling rate may be controlled by the quantity and configuration of lagging, the immersion depth of the cooling vessel in the cooling bath, the quantity of liquid in the vessel or the number and size of the ampoules containing the samples. The transition of cooling rate may be temperature-controlled or time-controlled. An example is directed to the cooling to - 79‹ C. in two stages of living bone marrow cell suspensions contained in ampoules placed in a rack and immersed in alcohol in a cooling vessel; the first stage of cooling, from room temperature to - 15‹ C. was effected at 1‹ C./ minute by immersion of the lower third of the cooling vessel (that portion being lagged with a layer of plastic, paraffin wax or other material of comparable thermal conductivity and of suitable thickness) in a mechanically agitated bath of alcohol and solid carbon dioxide held at a temperature of - 79‹ C. When the cell suspensions had reached the temperature of - 15‹ C. a solenoid, which had previously been supporting the framework carrying the cooling vessel, operated to drop the frame under gravity to a second position defined by a stop, at which position the cell suspensions cooled at a rate of 5-10‹ C./minute during the second stage. Throughout the operation, the liquid in the cooling vessel was stirred and the temperature was recorded through a platinum resistance thermometer; the stirrer consisted of a vertical rotating shaft which carried one or more propeller blades and was mounted in a cylinder open at both ends such that fluid was drawn up through the cylinder. A fan was operated from the commencement of each stage until the cell suspensions had reached temperatures of + 5‹ C. and - 40‹ C., respectively, to disperse froth forming on the surface of the cooling bath. The means for altering the cooling rate are described with the aid of electrical circuit diagrams.

Abstract: 1,175,866. Digital transmission systems. STANDARD TELEPHONES & CABLES Ltd. 30 May, 1968 [6 June, 1967], No. 26061/67. Heading H4P. To reduce the effects of error bursts the bits of a group of digital data words, each consisting of a multi-bit character and a corresponding error-correcting multi-bit check signal, are rearranged so that no two adjacent input bits are adjacent when transmitted. As described, the words consist of 5-bit characters and 5-bit check signals. Five such words are passed to a 50-bit shift register which has each stage connected via a gate to a corresponding stage of a second 50-bit register. The interconnection is such that when the second register is read out for transmission all the first bits of the 5-bit characters are transmitted first, followed by the first bits of the 5-bit check signals. Then the second bits of the characters and check signals are sent, then the third, and so on. This ensures that any error burst less than 6 bits long will not effect more than one bit in any one character or check signal, the check signal being such that single bit errors can be corrected. At the receiver the transmitted signals are reformed to their original order by apparatus similar to that at the transmitter.

Title: Improvements in and relating to the purification of wax obtained from peat
IPC: C10G73/00
Filed: 1937-09-27
Abstract: Peat wax is purified by boiling the crude wax with an aqueous solution of borax and sodium acetate and removing the aqueous solution containing the dissolved resin.  Tarry or pitch-like material in the resin-free wax is then removed or modified by either (a) treating with a differential solvent, e.g. a petroleum solvent in which the pitch is insoluble, or, butyl acetate, tetrahydronaphthalene or decahydronaphthalene in which the pitch is more soluble than the wax, (b) treating with acid followed by a mild alkali, e.g. hydrochloric followed by calcium or magnesium oxide or sulphuric acid followed by sodium carbonate, or (c) treating with phosphorus pentachloride or antimony pentachloride. The melting-point and hardness of the resin and pitch free wax may be increased by treating with sufficient caustic alkali to combine with the free acids, and then converting the alkali soap, in whole or in part, into a calcium or magnesium soap by the addition of a water-soluble calcium or magnesium salt.  The melting-point of the resin and pitch free wax may be increased and the acid value decreased by treating with triethanolamine, ammonia, phenylhydrazine or a phenylhydrazine salt, or a -naphthylamine, or the acid value may be decreased by treating with alcoholic potash.  The resin and pitch free wax may be bleached by treating with nitric acid or nitric acid dissolved in glacial acetic acid, or by dissolving the resin in a solvent stable to nitrogen peroxide, e.g. carbon tetrachloride, or trichlorethylene, and passing in nitrogen peroxide.
