Title: Improvements in or relating to pulse synchronising systems in pulse-actuated electronic apparatus
Inventor: COOMBS ALLEN WILLIAM MARK
IPC: H03L7/00
Filed: 1954-01-13
Abstract: 760,824. Pulse. generator synchronizing systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 28, 1955 [Jan. 13, 1954], No. 1051/54. Class 40(6) A pulse, synchronizing system for pulse actuated electronic apparatus employs a standing wave as a synchronizing signal which is transmitted to pulse generators of the apparatus to control and synchronize the timing of the pulses generated by the generators. By this means the phase delay which would normally occur when pulses of very short duration are transmitted down a delay line for synchronizing purposes is avoided since the standing wave is arranged to have only small differences in amplitude along the transmission path and has the same phase at all points of the path. The transmission line comprises a cable to which a sinusoidal voltage is applied the cable being divided into sections of less than one half wave-length at the sinusoidal frequency the sections being terminated in impedances such that a standing wave of constant phase throughout the cable lengths is obtained. It is shown that if each section of the cable has an electrical length of approximately #/3 radians a variation in voltage of only some 13 per cent will occur along the length of the cable. A number of such cable sections may be connected together in series the unconnected ends of end sections of cable being terminated in impedances such that the ,ends are of the same voltage thus these ends may be connected together so that the cable provides a ring main for feeding the standing waves to the various items of electronic equipment in the apparatus. At the various items of equipment means are provided for generating a synchronizing pulse at some identifiable point of the sinusoidal wave-form, for example when the voltage changes from negative to positive. Figs. 3 and 4 show that if the end sections of the transmission line are terminated in inductive reactances of value #3 jz0 where z0 is the characteristic indepedance of the line and if the intermediate sections of the cable have a terminating impedance of one half this value then the required variation in voltage along the cable which should not exceed 13 per cent is obtained and the standing wave will have the same phase at all points along the cable. The terminating impedances of the ends of sections of the cable are calculated to be equivalent to the cable lengths which are omitted but which would carry that part of the standing wave. Alternatively, equivalent filter networks could be used.

Abstract: 662,769. Grinding non-circular profiles. MUSYL, R. Jan. 17, 1949 [Jan. 24, 1948], No. 1272/49. Class 60 A device for producing non-circular profiles, particularly those on cams, in which a grinding process is effected in such a manner that the centre of the grinding wheel is always situated on the normal to the profile at the point where the latter makes contact with .the grinding wheel, is characterized in that two master cams are provided which control the movements of the tool by means of movable elements. The work 19 is rotated at a constant angular velocity by a synchronous motor while a compound motion is imparted to the grind. ing wheel 3 by two co-axial cams 1, 2 also driven by a synchronous motor in timed relation with the work. The cam 2 produces vertical movement of the grinding wheel through a lever 5 having a fixed pivot 4, while the cam 1 produces horizontal movement through a slide 13. The latter bears on a roller 15, which together with the grinding wheel is journalled at the end of a lever 7 pivoted to the free end of the lever 5 and biassed by a spring 16. Pulleys 21, 22, and 23 are provided for the belt drive to the grinding wheel from a motor 20 which is fixedly mounted on the machine frame. Shafts with a number of cams may be ground in a machine such as that shown in Fig. 10. The camshaft is supported between a headstock 41 and a tailstock 42 mounted on an adjustable table while each grinding unit is adjustable in both the longitudinal and transverse directions of the camshaft. A change-speed device for each grinding wheel is provided, and a number of pairs of master cams may be arranged on a shaft which can be adjusted axially by a handwheel 39 to bring the required pair into operation.

Title: Improved propeller pitch control
IPC: B64C11/42
Filed: 1953-01-16
Abstract: 724,654. Variable - pitch propellers. GENERAL MOTORS CORPORATION. Jan. 16, 1953 [Jan. 16, 1952], No. 1305/53. Class 114. A low-pitch stop prevents the pitch falling below a predetermined amount when in flight but this stop can be overridden when'the aircraft is supported on a landing surface. A governor 120 controls solenoids actuating valve 6 and so adjusting pitch to maintain a speed. A speed responsive valve 7 controls a high and low pitch setting, but this is also moved by the cam 102 to maintain a minimum low-pitched position when in flight. A parallel linkage from the propeller blade opens the switch 104 to override the governor 120. When on the ground, however, the parallel switch 110 is closed, thus bringing solenoid 43 into circuit to actuate valve 6 and so further reduce the pitch, until the fluid pressures on piston 72 balance.

Abstract: 313,514. Becker, A. June 13, 1928, [Convention date]. Bacteria, cultivating; vaccines.-Bacteria for use in the preparation of vaccines are cultivated on a medium free from animal albumen and containing undiluted juice obtained by expression from vegetable substances and particularly from fruits rich in sugar and poor in acid, together with a vegetable thickening substance such as agar. According to an example, juice obtained from ripe bananas in a filter process is sterilized at 40‹ to 50‹ C., 0.5 per cent common salt and 2.3 per cent agar are added, and the whole filtered in a current of steam at 100‹ C., made weakly alkaline with 10 per cent soda solution and finally sterilized in a current of steam. It is stated that bacteria grow on this media without the production of toxic product and that cultures for use as vaccines may be obtained in periods of from two to twenty hours. Tubercle bacilli, and other bacteria obtained directly from the patient for use as vaccines in numerous specified diseases may be cultivated. The bacteria after cultivation are washed off the culture medium with salt solution containing a little phenol, killed by heating to 54‹ to 60‹ C., and suitably diluted. The known use as culture media of albumen preparations, slices of potato, carrots, apples and bananas, and the filtrate from boiled dried plums treated with agar, is referred to The Specification as open to inspection under Sect. 91 (3) (a) does not restrict the invention to media containing agar or other thickening agent.

The wall members 3 may form a cylindrical surface but they may also be shaped to form a polygen having curved sides. In a preferred embodiment each member 3 has the curvature of an involute segment the base circle of which is less than and concentric with the drum 1.

Bright metal coatings are electrodeposited by a modification of the process of parent Specification, in which instead of the organic sulphonic acid brightening additive thereof there is employed a water-soluble compound which contains no sulphonic acid groups or metal atoms but contains at least two carbon atoms each of which is linked exclusively with three heteroatoms each selected from oxygen, sulphur, and nitrogen, said carbon atoms being joined together through one of their hetero-atoms by a short chain divalent hydrocarbon residue which may be substituted and/or interrupted by oxygen, sulphur, or nitrogen atoms or groups derived therefrom, and at least one of said hetero-atoms on each of the carbon atoms being a sulphur atom which either is bound to the carbon atom by a double bond or is in turn linked to said divalent residue. Typical additives contain two or more radicals from thioureas or isothioureas, thiocarbamates, dithiocarbamates, xanthogenates, and trithiocarbamates. The baths may also contain organic sulphonic acids or salts thereof in which the hydrocarbon radical is substituted by a halogen atom or by a cyano or thiocyano group, and in addition a polyhydroxy alcohol and/or a polymerization product of a low molecular weight unsaturated carboxylic acid or salt thereof. The invention is applicable to bright plating with brass, bronze, copper, nickel, zinc, silver, and cadmium, typically from baths at 70‹ C. Iron sheets plated with cyanide copper may receive a bright copper deposit from sulphate baths. Reference has been directed by the Comptroller to Specification 787,186.
