Abstract: 902,715. Grinding. BANKO, G. Dec. 23, 1959, No. 43730/59. Class 60. A compound angle grinding attachment, for surface grinding machines having a motor-driven wheel spindle, includes a stationary table adapted to be secured in various angular positions, a sub-table slidably mounted on the underside of said stationary table, an auxiliary spindle with a pulley and grinding-wheel mounted thereon journalled on said sub-table, a worm housing mounted on the stationary table, a worm shaft journalled therein and including a pulley, a crank-shaft journalled in the stationary table perpendicular to the lower face thereof and including a worm gear engaged with the worm shaft, a crank-arm mounted on said crank-shaft below the stationary table and rotatable with the crank-shaft, and a connecting-rod means pivotally connected at one end to the sub-table and at the other end to said crank-arm, to reciprocate said sub-table longitudinally of said stationary table upon rotation of said crank-arm. A bracket 11 has a split collar 12 embracing the housing 67 of the motor-driven grinding- wheel spindle 29 of a surface grinding machine 30. The bracket is secured, by tightening a bolt 14, in the desired angular position as indicated by a scale or part 13 of the bracket cooperating with a pointer 35 mounted on the column 31 of the machine. A table 15 is pivotally secured to the underside of the bracket 11 by a bolt 22 and is secured, by tightening bolt 22 and also bolts 18, 19 located in arcuate slots 16, 17 in the bracket 11, in the desired angular position as indicated by a scale 28 on the table 15. A sub-table 49 is slidably mounted on the underside of the table 15 and has journalled therein a spindle 62 carrying a grinding-wheel 64 and a double sheave pulley 63 driven by resilient belts 70 from a pulley 60 mounted on the spindle 29. The pulley 60 also drives, through a resilient belt 66, a pulley 39 on a shaft 37 journalled in a housing 36 on the table 15. The shaft drives, through worm gearing 38, 41, which can be rendered inoperative by loosening nut 43, e.g. when it is desired to dress the wheel 64, a shaft 40 carrying a part 44 with a radial slot in which a block 25 is adjustable by a micrometer screw 46. A link 57 is pivotally connected to the block 25 and to a stud 55 on a lever 53 pivoted on the table 15; a link 58 is pivotally connected to a stud 56 on the outer end of the lever 53 and to a pivot pin 59 secured to the sub-table 49 whereby the latter is reciprocated.

[Also in Division G3] In a centrifugal governor for an impulse transmitter, the shaft, the spring member connecting the shaft to a flyweight and the flyweight itself are all formed during manufacture as a one-piece moulding. Preferably the worm gear for driving the shaft is also integrally moulded therewith. The moulding is of plastics material, e.g. polyacetal resin, as also is the cup which encloses the governor and acts as a brake plate for the flyweight. The governor's speed is adjusted by removing material from the mould during the initial stages of manufacture or by removing material from the moulding so as to lighten the flyweight or change the rigidity of the spring member after manufacture. Alternatively a movable collar may be mounted on the spring member. The governor may be utilized in a conventional trigger dial set or in the set described in Specification 1,147,601.

Abstract: 1,118,281. Transistor circuits. E. K. COLE Ltd. 15 Feb., 1966 [16 Nov., 1964], No. 46498/64. Headings H3A and H3T. In a monitoring circuit of the type in which a checking signal is gated to an indicator in dependence on the state of the majority of a number of control signals, each control signal is applied to at least two transistor gates. In one embodiment, Fig. 1, each control signal comprising a pulse train applied at 4, 5 or 6 is rectified to provide the collector supply for two of the transistors 1, 2, 3. With at least two control signals normal, all stages are provided with a collector bias, and a checking signal applied to terminal 19 is fed to the output stage 20. Should two signals go abnormal, one of the stages 1, 2, 3 receives no collector bias, and the checking signal is inhibited. In a modification, Fig. 2 (not shown), four control signals are applied, each providing collector bias for three stages of a six stage circuit. In a second embodiment, Fig. 3 (not shown), each of three control signals provides the collector bias of one, and the base bias of another, of three parallel connected transistors (1, 2, 3). As long as two control signals are normal at least one transistor will be biased to a conducting state and the checking signal will pass to the output, but should two go abnormal, then all three transistors will be cut off (either by their collector or base bias) and the checking signal is inhibited. The control signal rectifier may be either a conventional diode rectifier. Fig. 4 (not shown) or a synchronous rectifier, Fig. 5, in which a positive potential occurs across capacitor 18 when the control signal pulse train at terminal 13 is in phase with a reference signal pulse train applied at terminal 14. In this condition the transistor 16 conducts during the negative going portions of the control signal to clamp them to earth. If, due to an abnormal condition, the control signal is delayed and arrives in antiphase with the reference signal a negative output is produced.

Abstract: 1367763 Titanium-tungsten mixed oxide sols and gels; titanium-tungsten carbide UNITED KINGDOM ATOMIC ENERGY AUTHORITY 1 Oct 1971 [5 Oct 1970] 47314/70 Heading C1A A sol or gel containing tungsten and titanium oxides is prepared by mixing freshly precipitated tungstic acid or a tungstate with an aqueous solution of a titanium salt. The tungstic acid may be prepared by dissolving the commercial acid cake in, e.g. ammonia and precipitating the acid in the cold. Alternatively ammonium tungstate may be used either in aqueous solution or as a solid. The preferred titanium salt is titanium tetrachloride. The temperature of reaction is not critical and may range from 0‹ to 100‹ C. or higher if an autoclave is used. It is preferred to use ammonium tungstate as the salt source since on drying the sol or gel a homogeneous mixed oxide free from sodium, calcium or other undesirable metals is obtained. Other refractory metals, e.g. tantalum, niobium, chromium and vanadium or non- refractory metals such as cobalt and bismuth may be incorporated into the sol by addition, e.g. as a chloride at any convenient stage in the preparation of the sol. The amount of added metal is not in general above 20% by weight of the titanium and tungsten. The sol may be dried and calcined to form a mixed oxide system. Finely divided carbon may also be introduced into the sol preferably as an aqueous dispersion or as a powder mixed with a wetting agent, prior to evaporation so that on calcining a mixed tungsten-titanium carbide is formed.
