Title: Blood cell typing and compatibility test procedure
IPC: G01N33/80
Filed: 1976-08-10
Abstract: A process for the determination of cell types or of cell compatability on a solid support material is described. In this process, a first cell layer is bound to the support material, these cells containing antigens or being provided with antigens. This first layer is then brought into contact with a solution which contains antibodies and, by means of immunoabsorption, antibodies are bound to the extent to which the antibodies of this solution are reactive with the antigens of the cells of the first layer. A suspension of second cells which carry antigens is then introduced, and the extent of the immunoadhesion of the second cells is determined by antibodies which are bonded to the first cell layer. In the process described here, the first cells, which are reactive, form a monolayer which is irreversibly bound to the support material. As a result, both agglutination tests and cell lysis tests can be substantially improved, and relatively unskilled personnel can carry out the tests in question.

Title: Light sensitive transfer material
IPC: G03F7/008
Filed: 1960-09-28
Abstract: 941,962. Photosensitive materials for stencil production. KALLE A. G. Sept. 28,1960 [Oct. 3, 1959], No. 33318/60. Headings G2C and G2M. A transfer material comprises a support carrying a watersoluble colloid layer and then a specified polyamide layer sensitised with a specified aromatic azido styryl compound. The specified polyamides are formed by polycondensation of (i) an #-amino carboxylic acid or (ii) of equivalent quantities of an #,#<SP>1</SP>-dicarboxylic acid and an #, #<SP>1</SP>-diamine or (iii) mixture of such aminoacid, diacid and diamine. It must contain an N- alkyl, N-alkoxy or N-alkoxyalkyl substituent on some of the amide N atoms unless formed from the mixture (iii). The specified azido compounds have the formula where R is aliphatic, aromatic or heterocylic; X is H,-SO 2 -NH-aryl or a group which forms a water-soluble alkali metal salt; and Y is H, acyl or carboxyl. Specified colloids are gelatine, size, starch, dextrin, dextran, a cellulose ether, polyvinyl alcohol, polyacrylamide or a polyepoxide. Procedure therewith is exposure as under a positive,pressure of the exposed side on to a screen e.g. of nylon, polyester or metal gauze which has just been wetted with 60-80% alcohol for a few minutes, and then a water treatment with removal of the support and the non-hardened parts of the layer to leave a stencil; any parts of the printing surface of which may be treated with alcohol to completely remove such layer. Five examples are directed to production of the material and a sixth extends to processing to a stencil, thus in Example 1 paper is coated with gelatine and then with a mixture of an aqueous etherolic solution of polyamide from adipic acid hexamethylene diamine and #-caprolactam with an aqueous glycol monomethyl ether solution of 4, 4<SP>1</SP>-diazido-stilbene-2, 2<SP>1</SP>-disulphonic acid sodium salt. Somewhat similarly, Examples 2-6 describe materials as with paper or polyterephthalic ester supports, size or polyvinyl alcohol colloid layers and then a variety of sensitised polyamide layers; and the processing procedure of Example 6 comprises, after exposure, pressing the material against a stretched "tissue" wetted with an aqueous alcoholic solution containing N- methoxymethylpoly- #- caprolactam, formaldehyde and hydrochloric acid and backed by a rubber mat, while the uncoated side of the exposed material is placed against a wetted felt web supported by a wood or metal plate; after 3 to 5 minutes pressure "tissue" and material are extracted, the paper support is peeled off and the stencil is treated with cold running water. It may be used for printing on paper, metals, ceramics, plastics or fabrics.

Abstract: 618,908. Crankshafts. WARSOP PETROL DRILL & TOOLS, Ltd., and GATEHOUSE, E. A. Nov. 11, 1946, No. 33483. [Class 80 (ii)] A crankshaft particularly for a percussive tool comprises two half shafts 16 with integrally formed crank arms 17 and balance weights 18. Cylindrical sockets 19 are formed in the crank arms for the reception of cylindrical spigots 22 formed on a crank-pin 21. At least one of the spigots 22 is slidably mounted within the corresponding socket 19 with a small amount of clearance. This diminishes the tendency for the shaft to twist or distort due to sudden changes in power transmission when each half shaft carries weights of different moments of inertia, i.e. a flywheel and a fan rotor. The central portion 23 of crank-pin 21 carries a roller bearing.

Title: Teleprinter communication system
IPC: H04L25/38
Filed: 1970-07-09
Abstract: 1321435 Telegraphy; synchronizing ANSTALT EUROPAISCHE HANDELSGESELLSCHAFT 9 July 1970 [29 Aug 1969] 33499/70 Heading H4P In a teleprinter communication system particularly employing a radio link, stop bits are shortened and synchronizing signals are transmitted in periods between information signals in order to maintain synchronism at the receiver. In the embodiment described serial signals from teleprinter 1 are stored in parallel at 2, then transferred through registers 3, 4 to a radio transmitter 5. The register 4 shortens the stop bit and in intervals between characters arriving from teleprinter 1 emits a series of stop bits. At the receiver 6 a flywheel synchronizer 7 adjusts itself to incoming characters, when these are more or less continuous, which are passed through distributer 8 to a receiving teleprinter 9. When teleprinter 1 is operated manually there will be gaps between characters, In previous systems flywheel synchronizer 7 had no incoming characters on which to synchronize with such marking. The periodic transmission of stop bits according to the disclosure prevents synchronizer 7 from wandering beyond certain limits. Whereas in prior art systems distributer 8 normally blocks stop signals from teleprinter 9, in the embodiment described these are passed forward and causes meaningless characters to be typed. Circuit arrangements for units 2-4 are described with reference to Fig. 2 (not shown).

Title: Improved servo-motor and its applications
IPC: B60T13/06
Filed: 1934-11-21
Abstract: 444,127. Brakes applied by speed-responsive devices. PIGANEAU, G. P., 152, Boulevard Malesherbes, Paris. Nov. 21, 1934, No. 33511. [Class 103 (i)] A mechanism for operating brakes and for other purposes comprises a centrifugal mass or masses provided with inclined radial grooves engaged by radial tapering flanges on plates slidably keyed on a rotatable shaft ; the axial movement of the plates operates the brake &c. There may be a series of centrifugal devices so arranged that the movement imparted by the several devices is added together. A rotatable shaft 11 has splined thereon a number of discs 16 provided with tapering radial flanges 17 received in correspondingly shaped slots formed in sector-shaped masses 20 surrounding the shaft. Thus when the shaft is rotated the discs other than. the lefthand one are moved to the right by the masses each to a greater extent than the preceding one. The movement of the right-hand disc is transmitted through a spring 23, disc 25, and a piece 26 sliding in a slot in the shaft, to a rod 28 thence to an arm 29 on the brake &c. operating shaft 30. A spring 36 returns the masses to normal position when the shaft ceases to rotate. The spring 23 acts as a shock-absorber and limits the pressure applied by the device. The cylindrical casing 1 of the device is mounted by arms 2, 2a on a pivot Y, Y, a Bowden cable 7 being connected to one arm whereby a roller 13 on the shaft 11 may be engaged under the action of a spring 5 with a rotating drum 12 to drive the device or, by tensioning the cable, the roller may be disengaged from the drum and contact with a fixed shoe 32 to stop the shaft. When the masses are in their outermost radial position they produce a torque by rubbing on the casing 1 which may cause the device to swing about the pivot Y, Y to disengage the roller 13 from the drum 12 with consequent fall of speed of the device and a return to the driving position, an intermittent driving action being thus set up. A chamber 33 connected by perforations with the casing 1 is provided to receive lubricant expelled from the casing when the device is rotating and which would otherwise hinder the rotation. When the device is used for operating the brakes of a motor vehicle, the pedal may, in addition to its connection with the cable 7, have a link connection to the shaft 30 for the direct operation of the brakes. The device may be mounted upon the gear-box and the driving drum 12 upon the driving shaft of the vehicle.

Abstract: 1,038,770. Adders. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 3, 1963 [Sept. 4, 1962], No. 33828/62. Heading G4A. An adder for binary-codeddecimal digits stores representations of the addend plus the value of each binary digit, combinations of these representations being accumulated dependent on the value of the augend. The addend digit d is stored in register 1 and is decoded by circuit 3 to mark 1 out of 10 lines, 20 to 29. Each line is threaded through sets of magnetic cores 4, 5, 36 and 38 so that the cores if switched would enter into register I the numbers d + 1, d + 2, d + 4 and d + 8, respectively, by way of sense lines 9 to 12. The augend digit is entered into register 2. Each binary digit, by its presence, opens a gate 7 which passes a read-out pulse to its associated register 4, 5, 36 or 37. Carries are provided for by the presence of an additional sense line which can set the " 1 " bit stage of the next higher order register 2. In operation, the lines 14, 15, 38 and 39 are pulsed successively, after which line 14 is pulsed sufficiently often to allow a carry to ripple through the orders. The Specification mentions that codes other than 1, 2, 4, 8 can be employed, in particular the 2-out-of-5 code.
