Title: Process for the production of foam plastic bands, strips or sheets
IPC: C08J9/42
Filed: 1966-06-22
Abstract: The walls of the pores or cells of a foam plastic band, strip or sheet, consisting substantially of an elastic material are covered, but the pores or cells are not filled, by applying to the foam structure an impregnating mass which is at least one molten substance other than asphalt bitumen.  The molten substance may be a fusible resin, either a single resin or a mixture of such resins the composition of which is adjusted to give the desired thermal stability to the foam plastic band, strip or sheet e.g. coumarone-indene resins, or hydrocarbon resins produced by polymerisation of unsaturated hydrocarbons; or hydrocarbon compounds such as paraffins or waxes having a melting point of, for example, 65 to 120 DEG C., to which a synthetic resin such as polyisobutylene may be added.  The molten substance may also contain age resistors and/or light protective agents, and non-melting components such as combustion resistors e.g. antimony trioxide or heavy spar, colouring pigments.  The foam plastic may be polyurethane, polyvinyl chloride, cellulose, or foam rubber. The material may be used for sealing purposes in buildings or may be adhered to stone, concrete, iron and non ferrous metals.  The material may be produced by passing the band, strip or sheet of foam plastic through the molten impregnating mass.

Title: Improvements in and relating to systems using lasers
IPC: H01S3/083
Filed: 1966-06-23
Abstract: 1,144,585. Lasers. PHILCO-FORD CORP. 23 June, 1966 [23 June, 1965], No. 28053/66. Heading H1C. A ring laser produces outputs of two distinct frequencies, one output being a reference frequency and the other a carrier frequency which may be frequency modulated. As shown, reflectors 10, 12, 14 together define a closed optical path which includes two active media 16, 18, each active medium comprising a helium-neon tube which is pumped by radiofrequency and has polarizing Brewster angle windows. The optical path includes a Kerr cell 26 and two 45 degree Faraday rotators which together cause the polarizations of the clockwise and anticlockwise light beams 40, 42, where they pass through the Kerr cell, to be rotated and then restored. The rotated polarization of beam 40 is parallel to the direction of a field applied to the Kerr cell by electrodes 28, 30, while the rotated polarization of beam 42 is orthogonal to this field. Consequently a bias voltage applied between the electrodes has little effect on the anticlockwise beam, so that its frequency remains substantially the same, but changes the frequency of the clockwise beam by effectively increasing its path length. The clockwise beam constitutes the carrier frequency which may be modulated by superimposing an A.C. signal from source 32 on the bias. The two. output frequencies are extracted by using a reflector 34 in association with reflector 14 which is partially transmitting, the reference (anticlockwise beam) frequency enabling demodulation by heterodyning and frequency discrimination to take place at a receiver 48. The difference in frequency between the two beams 40, 42 may be stabilized by sampling in the output path 36 and using the D.C. output of a discriminator to control the bias potential. Modulation may also be effected by cells employing stress induced or magnetic field birefringence.

Filed: 1931-10-09
Abstract: 382,404. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and FLYNN, G. W., of General Electric Co., Stoke, Coventry. Oct. 9, 1931, No. 28083. [Class 40 (iv).] Two levels of a selector lead to a single group of outlets, the level over which the outlet was seized being passed forward to effect discrimination at a succeeding exchange by means of marginal currents over a two-wire junction. The repeater shown can be seized over level SA with private wire X, or SB and Y. If seized over SB, PB operates and short circuits the outgoing junction loop to operate AS and marginal relay M at the distant exchange. If seized over SB, PB is not operated and only AS operates when the loop is extended. The incoming selector operates in the usual way except that if M is operated, a low resistance path is presented over P by K and m2 to enable a polarized discriminating relay in a succeeding selector to be operated. The further selector may be of the type described in Specification 382,051. The Provisional Specification states also that simplex signalling may be used to pass the discriminating signal over the junction.

Title: Improvements in and relating to the purification of antihaemophilic globulin
Inventor: TUNNAH GEORGE WILLIAM
IPC: A61K38/00
Filed: 1958-09-03
Abstract: A process for the preparation of a fibrinogen-reduced antihaemophilic globulin (A.H.G.) solution comprises treating an aqueous buffered solution of mammalian blood plasma or a crude concentrate containing A.H.G. derived therefrom at a pH of 6 to 8 with an ion exchanger whereby only a proportion of the total available protein, controllable by adjustment of the ionic strength of the solution, is adsorbed, but that this adsorption is selective for the A.H.G. component, followed by washing the ion exchanger free from unadsorbed material with an aqueous buffer solution at the same pH and of the same ionic strength or slightly less than that employed for adsorption then followed by eluting with an aqueous salt or buffer solution at a greatly increased ionic strength to that of the original aqueous buffer solution and within the pH range 6-8 to produce the purified A.H.G. solution in which the A.H.G. is associated with less fibrinogen than was the original solution. Specified ion exchangers are carboxylic ion exchange resins derived from methacrylic acid and cross-linked with divinyl benzene, basic ion exchange resins derived from cross-linked polystyrene carrying quaternary ammonium groups and cellulose derivatives carrying diethylaminoethyl groups.  Aqueous phosphate buffers e.g. sodium phosphate and citrate-phosphate buffers are used as buffers.  For acidic exchangers when adsorbing, the buffer should be at a molarity of 0.2-0.3 M and for basic exchangers at a molarity of 0.15-0.5 M. Elution from an acidic exchanger is facilitated by increasing the pH and from a basic exchanger by lowering the pH.  The eluting phosphate buffer solution should be of a molarity of 0.6-0.7 M or alternatively a 4-6% solution of sodium chloride buffered with phosphate pH 7, molarity 0.1 M, may be used.

Abstract: 1378920 Tyre pressure sensing AVCO CORP 18 Oct 1972 [15 Sept 1972] 28384/74 Divided out of 1378919 Heading B7C [Also in Division H3] A complementary pair of transistors Fig. 3, operates an indicator connected at 206A to T205A collector, in response to pulses received at, and stretched by, a rectifier-capacitorresistor circuit 57A from sensors on a vehicle which respond to low tyre pressures. The tyre pressure sensing system is as described in parent Specification 1,378,919. The complementary transistor circuit stretches the pulses received from the sensing circuits which are spaced apart due to the fact that the wheel sensors and transmitters and fixed receiving antennae co-operate only for a portion of each rotation. The stretching is necessary to reliably operate the indicator which may be aural or visual. In the circuit shown, the positive feedback resistor 207A is selected to enhance switching in response to received pulses and to provide hysteresis, but is not sufficient to latch the circuit if the pulses wholly disappear.
