Title: Process for polymerizing olefinically unsaturated hydrocarbons
Inventor: DOST NICOLAAS
IPC: C08F2/00
Filed: 1955-11-18
Abstract: Olefins such as ethylene, propylene and butylene are polymerized, using Ziegler type catalysts, in the presence of solvents which have been purified by treatment with Ziegler catalyst components, prior to the addition of catalyst to the solvents or to the formation of catalyst therein.  The Ziegler type catalysts and components thereof may be those disclosed in Specifications 799,392, 799,823 and 801,031, and particular components used in the purification are titanium tetrachloride and/or aluminium diethyl monochloride.  The solvents specified are pentane, hexane, heptanes, iso-octane, cyclohexane, benzene, toluene and dichlorobenzene.  Preferably, the solvents are pretreated, before purifying as above, by successively washing with concentrated sulphuric acid, water, alkaline solution, and then water again, followed by drying (e.g. with CaCl2 and/or Na), and then optionally distilling or treating with and adsorbent such as alumina.  The olefins may also be purified by treatment with a catalyst component as above, e.g. aluminiumtriethyl or -diethyl monochloride, preferably in hydrocarbon solution.  In an example, ethylene is added continuously during the polymerization. Purification of the polyolefins obtained and deactivation of catalyst, e.g. with methanol, methanolic hydrochloric acid and water (which may contain ethylene oxide/octyl phenol condensate as surfactant), is less troublesome and the products are of more constant molecular weight.  Shaped objects and copolymers are claimed.  Specifications 619,231 and 742,642, [Group IV (b)], also are referred to.

Title: Parity bit generator
IPC: G06F11/10
Filed: 1959-10-02
Abstract: 862,281. Digital electric calculating circuits. NATIONAL CASH REGISTER CO. Oct. 2, 1959 [Oct. 22, 1958], No. 33436/59. Class 106 (1). Signals corresponding to the binary representation of a number are applied to a parity bit generator comprising a number of comparator circuits arranged in tree formation so as to have an output according to whether the number is odd or even. The output can be used where necessary to provide a "parity bit," or in dealing with a full parity-bit code can be used to detect an error. Fig. 1 shows an example using PNP transistors for computing the parity bit to be added to a 7-bit code to ensure that the number of 1's in the code shall always be odd, the necessary output being then taken at 49 from inverter 48. Alternatively, if the code is to be even the output is taken at 47. The circuit is made up of a number of two-transistor comparators of the type described in Specification 844,966 in which like inputs produce a low-voltage output, whereas unlike inputs produce a highvoltage output. The circuit can be modified to have eight inputs when it acts as a check on the odd or even parity code, an error bringing up an alarm.

Class 57 A speed regulation device for the internal-combustion engine of a road vehicle comprises a variable speed device 18, 19, Fig. 1, driven at a speed proportional to the road speed of the vehicle and fly weights 39, 40, Fig. 3, mounted on the driven shaft 25 of the device and adapted to actuate a push-rod 41 to-close an electric contact to a solenoid 76, Fig. 6, at a predetermined road speed, the solenoid operating a butterfly valve 65 in the inlet pipe to the engine. The variable speed device consists of a disc 18 driven by gearing 7 from the speedometer drive 1 and a disc 19 mounted on a swinging arm 24 and held in contact with the disc 18 at a radially-adjustable position by a spring 33. The push-rod 41 is loaded by a spring 50 and passes through a bore in the shaft 25 to a position opposite the operating member 44 of a switch 26 which is connected in circuit with the vehicle battery and the solenoid 76. When the latter is energized, a plunger 78 is displaced to rock a lever 67 connected to the butterfly valve 65 through a rod 70 of adjustable length. A spring 74 returns the valve to its original position when the solenoid is de-energized. The valve is mounted in a flange 61 which is arranged between the carburetter and the intake pipe of the engine. In a modification, a torsionally-loaded shaft 87, Fig. 11, connected by a coupling 101 is released to rotate the valve when a plunger 110 is displaced against the resistance of a spring 112 by energization of the solenoid 76, the plunger serving to operate a clutch 111. An accelerator or hand control is connected to the unit by a band clip 120 and stirrup 121. In a further modification, the solenoid and the accelerator or hand control are connected by a pair of spring-coupled levers mounted on a common shaft. To enable the device to be put out of action in an emergency, a switch is provided in the cab of the vehicle to control a solenoid which separates the wheels 18, 19 of the variable-speed device, the solenoid being automatically deenergized after a predetermined time interval by a thermostatically-operated switch mounted adjacent a heater element which is switched on simultaneously with the solenoid for separating the wheels 18, 19.

The 200 outlets provided by the verticals of BS 1... BS20 are divided into 10 sets, conveniently termed levels, which are multipled over a number of group selectors. Thus any inlet of the network may be connected to any outlet. For the purpose of control all the switching units are served in common by two similar digit-responsive circuits one of which is allocated to a call and serves to determine an idle path between a particular inlet and an idle outlet of a defined group, the appropriate cross-point relays being controlled over two sets of marking wires. An outlet group may occupy a single level or two or more levels or parts of levels, and the control circuit is arranged by means of cross-connections to test over several levels in succession when required. The control circuit includes a register responsive to digital signals in VF form, e.g. of the kind described in Specification 1,122,141, and has means for recording the failure to complete a connection through the group selector.
