Title: High molecular weight linear polyesters
Inventor: LOHWASSER HERMANN
IPC: C08G75/23
Filed: 1968-10-11
Abstract: 1,208,825. Linear polyesters of polysulphones. FARBENFABRIKEN BAYER A.G. 11 Oct., 1968 [3 Nov., 1967; 27 Nov., 1967], No. 48289/68. Heading C3R. Linear polyesters are made by reacting a dihalide of an aromatic dicarboxylic or disulphonic acid (of formula X-CO-R<SP>1</SP>-COX or X-SO 2 -R<SP>1</SP>-SO 2 -X, wherein X= halogen, R<SP>1</SP>=as below) with an aromatic dihydroxy compound of general formula wherein R (R<SP>1</SP> similar to R but not necessarily the same) represents a bivalent aromatic radical which may or may not be substituted, selected from the group consisting of phenylene, naphthylene, or diphenylene or a radical of the general formula wherein Z represents sulphoxide, sulphonyl, carbonyl, oxygen, alkylene, cycloalkylene, alkylene phenylene, or alkylene naphthylene, A and B each represents a halogen atom or an alkyl or alkoxy group, a and b each represents 0 or an integer from 1 to 4, and n represents an integer from 3 to 20. The reaction mixture may also include a monomeric dihydric phenol. The reaction is carried out in polar organic solvents (preferably by the interfacial process) in the presence of acid binding agents between 10‹ and 40‹ C. In the examples the acid dihalides used were isophthalic acid dichloride, benzene - 1,3 - disulphochloride, and diphenyl ether-4,4<SP>1</SP>-disulphochloride.

Title: Data processing system and method therefor
IPC: G06F12/08
Filed: 1973-10-17
Abstract: 1449229 Data processing AMDAHL CORP 17 Oct 1973 [30 Oct 1972] 48429/73 Heading G4A In a data processing spstem having a central processing unit (14, Fig. 1 not shown), and main storage (MS) coupled to high speed: buffer storage (12, 13) in parallel mode for transfer of a predetermined number of bytes in one cycle of operation, gates are included for coupling pairs of outputs of the buffer storage to a word register 37 (Fig. 2) from which data is transferred to the CPU so that a fraction of the predetermined number of bytes are transferred in one cycle.  As described data is moved between the main storage and buffer storage in 8 byte configuration and between the buffer store and central processor unit in 4 byte configuration. A line of information (32 bytes) is transferred from main storage to the buffer during four cycles. The first 8 bytes are stored in locations 0-7, the last 5 bits of an address indicating that storage is to start in the location 0, resulting in enable lines 0, 1, 2, 3 (Figs. 5A, 5B, 6A, 6B not shown) and, since it is an 8 byte transfer, lines 4, 5, 6, 7 being energised. The system operates similarly to transfer data to main storage. When 4 bytes are fetched from the buffer, alignment may be necessary so that the bytes appear with the lowest address byte on the set of leads of least significance. This is effected using four selectors (W, X, Y, Z) to each of which all four bytes are fed, with data on lines A and E, E and F, C and G and D and H being bundled, a selected byte being fed through each selected to the word register in accordance with control signals derived from the two least significant bits of the lowest addressed byte. If for example bytes 17-20 are requested, the data is read out from buffer storage on lines B, C, D, E respectively, the data on lines B being fed via the first selector to the lowest level output leads (W, R, O). If less than 4 bytes are requested non specified byte positions of the word register are forced to zero with a "1" parity bit. Data transferred between the central processing unit and buffer storage is similarly aligned.

A method of making a seamless tube includes the steps of (a) centrifugally casting a tube having a greater diameter and wall thickness than the finished tube and allowing the tube to cool, (b) smoothing the walls of the tube by turning or grinding, (c) heat treating the tube to remove any stresses set up in the machining operation, (d) cold-working the tube over a mandrel by rockers or rollers to reduce the wall thickness of the tube and so lengthen the tube and (e) hot working the tube in a rolling mill in which the rollers stretch the tube and reduce the diameter of the tube to produce the finished tube. In the centrifugal casting step, Fig. 1 (not shown), molten metal from an induction furnace is poured by a ladle at a controlled rate into a metal mould lined with porous ceramic material. The casting apparatus may be surrounded by an inert atmosphere such as argon, or a reducing atmosphere such as hydrogen.

The pressure is established in the chamber 31 through a bore 40 in communication with the working chamber 41 and containing a sintered metal insert 42. Alternatively, the chamber 31 may be pressurized through passages (54, 56) containing calibrated restrictions and connected, respectively, to the pump's suction and delivery pipes (51, 53).

Abstract: 1,085,659. Control of motors; fluid actuation of switches. TRICO PRODUCTS CORPORATION. Dec. 16, 1964 [Dec. 16, 1963], No. 51219/64. Headings H2B and H2J. [Also in Division A4] A windscreen cleaning system comprises a wiper motor and a control system for the motor to provide controlled dwell periods, the control system having a timing network actuating a circuit interrupter having contacts in circuit with the motor, and means for applying input energy pulses to the timing network which has means for converting input energy pulses to output energy pulses of a controlled duration independent of the duration of the input energy pulses, and means for applying the output pulses to the circuit interrupter. The control system for the motor includes a relay 74 having contacts 72, 76 in parallel with a parking switch 68 operated by a cam 142 on the output shaft of a gear reduction unit and only opened when the wiper blades are in a parked position. The relay contacts are normally closed but are opened when the relay is energized by a transistor 86 having its base biased negative which is effected by the charging of a condenser 94 when a switch 98 is closed by the cam 142. The discharge time of the condenser is controlled by a variable resistor 34. When the condenser completes its discharge, the negative bias on the base of the transistor is cut-off and the collector emitter ceases to conduct allowing contact 76 to close and re-start the motor to effect another cycle. A vacuum-operated switch 44 connected to the manifold 48 of the vehicle is disposed across the variable resistor 34 which is thereby short-circuited when the vehicle is accelerating so that the condenser is rapidly discharged and the transistor ceases conducting to close the contacts 72, 76 before the parking switch 68 is opened, the motor thus operating continuously. The switch 44, Fig. 4, consists of a'base part 164 of insulating material on which is a fixed contact 118b and a contact 118a which is movable by a diaphragm 174 in a chamber 173 formed by the base and a cover 162. The chamber has two compartments 173a and 173b the former containing a spring 176 and being connected by a conduit 46 to the manifold of the vehicle.
