Patent GB-1474110-A (GB)
Title: Apparatus for setting a counter to a given initial count
IPC: H03K21/38
Filed: 1974-05-07
Abstract: 1474110 Resetting and reading electronic counters COMPTEURS SCHLUMBERGER 7 May 1974 [14 May 1973] 19963/74 Heading G4B In order to zeroize or preset a counter 52 pulses are fed from a clock 64 to its count input 54 by a gate 62 which is enabled only while the count in the counter is not at the desired value. A switch 60 selects whether the counter is connected to A for counting, to B for presetting or (Fig. 4, not shown) to C for reading out. On a simple arrangement (Fig. 2, not shown), a comparator directly sensing the condition of the counter bi-stables determines when the gate is disabled. In Fig. 3, the gate 62 is enabled by a bi-stable 66 to apply pulses to the counter. When the counter overflows to zero a pulse at 56 sets a bi-stable 70 which enables a gate 72. A counter 74 then counts up to N and its overflow pulse resets bi-stable 66 to disable gate 62; the counter 52 is thus preset to value N. If resetting to zero only its required counter 74 and bi-stable 70 are omitted and the overflow pulse from 56 applied to reset bi-stable 66; if the output of the gate 62 is fed to a downcounter (86, Fig. 4, not shown) it will record the count in the counter 52 before zeroizing. By these means the counter 52 can be zeroized, preset or read-out without making any connections to its individual stages. This reduces stray capacitances and allows counter 52 to operate at maximum speed.

Title: Improvements in and relating to photo-electric cells
Inventor: JENKINS JAMES ARCHIBALD
IPC: H01L31/08
Filed: 1952-08-07
Abstract: The photo-sensitive layer comprising lead sulphide, selenide or telluride, in a photoelectric cell is subjected to after treatment comprising opening the cell to atmosphere for between 1 and 5 minutes, re-evacuating and sealing the cell and then giving it a final baking at 100 DEG  C. until its sensitivity is at a maximum.

Abstract: 662,117. Warping machines; stop motions. PATRA PATENT-ADMINISTRATION & TRADING CO. July 29, 1949 [Aug. 17, 1948], No. 26022/49. Class 142(iv). An electric stop motion for a warping machine comprises pivotally mounted individual feelers 9, one for each thread, arranged so as to be supported by the threads and operatively secured to levers 11 carrying contact members 17. Each thread passes from its bobbin 8, through a stationary thread guide 5<SP>11</SP> around a dome-shaped porcelain tensioning device 6, under the corresponding feeler 9 and through a second stationary guide 7 to the reed of the warping machine. Upon thread breakage, the feeler 9 swings downwardly to rotate the lever 11 so that the contact 17 engages a contact blade 16 to close a circuit and stop the machine. A light bulb is provided in the circuit to indicate the thread broken.
Patent GB-805153-A (GB)
Title: Production of ferric chloride and phosphorus trichloride
IPC: C01G49/00
Filed: 1956-06-28
Abstract: <PICT:0805153/III/1> Phosphorus trichloride and ferric chloride are obtained by mixing fully chlorinated ferrophosphorus with unchlorinated ferrophosphorus at 270-486 DEG  C., whereupon phosphorus trichloride is evolved, and chlorinating the residue at 315-486 DEG  C. whereupon ferric chloride sublimes.  In the illustrated continuous process ferrophosphorus is chlorinated at 500-1200 DEG  C. on a grate in vessel 2, the liquid product collecting in 3.  Gases evolved are passed through a bed 4 of finely divided ferrophosphorus which absorbs phosphorus and titanium compounds, leaving silicon tetrachloride which is condensed at 5. The chlorinated and unchlorinated materials are mixed in vessels 6, 61 alternately while the residue in the other vessel is being chlorinated.  The ferric chloride is collected in vessel 8.  The impure phosphorus trichloride is condensed at 7 and redistilled at 10 to produce gaseous fractions of silicon tetrachloride and phosphorus trichloride and a solid residue containing titanium tetrachloride and phosphorus oxychloride, which are separated as described in Specification 805,154, by treating with ferric chloride to liberate titanium tetrachloride and phosphorus oxychloride, and recycling the residue to 3.  Specification 312,685, [Class 1 (ii)], also is referred to.

IPC: C07H23/00
Filed: 1932-07-18
Abstract: Complex double compounds are prepared by the interaction of heavy metal compounds of thiocarbohydrates with alkali or alkaline earth metal compounds of thiocarbohydrates.  The products, which are stable and readily soluble, possess therapeutic properties. The heavy metal compounds of thiocarbohydrates employed as starting materials are prepared by the processes of Specifications 293,363, [Class 2 (iii), Dyes &c.], and 386,562.  Examples are given of the preparation of double compounds of (1) sodium thioglucose with the gold, silver, antimony, arsenic and nickel compounds of thioglucose, (2) sodium thioglucose with aurothiogalactose, and (3) sodium thiocellobiose with gold thiocellobiose.  The Specification as open to inspection under Sect. 91 describes also the interaction of heavy metal compounds of thiocarbohydrates with the thiocarbohydrates themselves and refers to the treatment of aurothioglucose with thioglucose. Salts are obtained by neutralization with basic agents.  This subject-matter does not appear in the Specification as accepted.

Substituents such as halogen, alkyl, alkoxy, aryl and aryloxy groups may be present in the arylene nucleus. Carboxylic, sulphonic and hydroxy groups are also mentioned.  The Specification as open to inspection under Sect. 91 refers to the use of hydroaromatic acid halides in general.  This subject-matter does not appear in the Specification as accepted.

Abstract: 188,371. British Thomson-Houston Co., Ltd., and Young, A. P. Aug. 2, 1921. Electric and magnetic.- For regulating the speed of a gramophone or the Like, a disc of conducting material is mounted on the record-carrying spindle, and caused to pass between the poles of a permanent magnet, the position of which is adjustable or the magnetic field variable. In the device shown in Fig. 1, the permanent magnet 2, between the poles of which the conducting disc 1 rotates, is mounted on a non-magnetic pin 3, so that it can be rotatably adjusted by means of a nut 4 in order to vary the position of the poles with respect to the periphery of the disc. Fig. 3 shows a modification in which the magnetic field through the disc 1. is varied by altering the distance between secondary pole-pieces 7 and 8, which provide a magnetic circuit in shunt with the main polepieces.

Title: Improvements in liquid fuel burning apparatus

Abstract: 478,438. Rotary pumps. SALLOT, L. E. July 27, 1936, No. 20730. Convention date, Aug. 2, 1935. [Class 110 (ii)] [Also in Group XI] In a liquid fuel burning apparatus in which fuel and air are supplied to a spray burner 1, Fig. 1, by pumps 2, 3 mounted on a shaft which may be driven at various speeds, the fuel is supplied to the pump 2 by a pump 5 having a greater output than the pump 2 and mounted on the same shaft. The pump 5 draws fuel from the reservoir 4 through a filter 10 and a loaded valve 11 operated by a diaphragm 13 subjected to the suction produced by the pump 5. A constant pressure is maintained at the inlet to the pump 2 by the excess fuel being returned to the reservoir 4 through a loaded valve 9. When the pumps stop the diaphragm 13 rises and withdraws the fuel from the burner and its supply pipe through the pumps. Fig. 2 shows a suitable arrangement of pumps 2, 3, 5 mounted in a casing 15 and driven by a shaft 16 which is fitted with different sized driving pulleys 17 according to the speed at which the shaft is to be run. The pump 3 has an eccentric rotor 23 fitted with blades sliding in recesses communicating with cutaway portions 24. A channel 25 in the casing 15 connects the delivery chamber of the air pump with the cutaway portions 24 to prevent the air pressure from impeding the movement of the blades. Fuel leaking from the pumps 2, 5, which are of the gear-wheel type, lubricates the shaft bearings and escapes through a channel 20 in the shaft to a groove 28 in the casing 15 to which any air leaking along the shaft can also pass. The groove 28 communicates with a chamber 21 through which the, air passes to the inlet channel of the pump 3. The pulley 17 is provided with flanges 29 which act as baffles to prevent dust being drawn into the pump 3.
