Title: Electrolytic grinding apparatus
IPC: B23H5/08
Filed: 1954-02-24
Abstract: 786,775. Resistance measuring. NORTON GRINDING WHEEL CO., Ltd. Feb. 24, 1954 [April 13, 1953], No. 5416/54. Class 37. [Also in Group XXXV] In a control system for an electrolytic grinder (see Group XXXV), the resistance at the interface between the work Wand the grinding element CR<SP>1</SP> is computed by passing interface current and voltage signals in respective opposed torque coils 134, 135 fixed to the shaft 131 of an electro-dynamometer device, the current signal being derived over a rectifier bridge RB<SP>1</SP> from saturable inductors 106 associated with the current leads. The coil 135 moves in the field of a permanent magnet 138, and coil 134 coacts with a fixed coil 137 energized in series with a resistor R13 from the output of a photocell-amplifier unit 145, 146, the latter being responsive to the position of shaft 131 by means of a mirror 141 reflecting light from a source 142 on to the photo-cells. Since the net torque produced by coils 134, 137 represents the product of interface current and photo-cell-amplifier output, and in the equilibrium position of the shaft this torque balances that due to the voltage coil 135, the output to resistor R13 represents the interface resistance. Specification 775,765, [Group XXXV], is referred to. Reference has been directed by the Comptroller to Specification 761,483.

One or more pairs of rollers in a roller briquetting press are mounted on two shafts each with its own drive, the two shafts or the two driving means being mechanically connected to ensure synchronous rotation. Two motors 10, 17 drive the shafts 1, 2 on which the rollers 3a and 3b, 3c and 3d are mounted, through gearings 8, 15 and through shafts 4, 11 which incorporate universal joints and couplings 5 and 6, 12 and 13 and on the ends of the gearing- output-shafts remote from the rollers are intermeshing spur wheels 19, 21. The number of mould cavities 22 or 23 or the circumference of a roller may differ by one from the number of teeth on each of the spur wheels, enabling any desired adjustment to be made, to ensure coincidence of the mould cavities, by axially moving one of the spur wheels out of mesh with the other and turning is through the required angle. One of the spur wheels may be clamped to its shaft to allow such adjustment without the axial movement. The apparatus is constructed in two parts to facilitate the exchange of rollers.

Title: Control rod for a nuclear reactor
IPC: G21C7/12
Filed: 1975-02-11
Abstract: 1465220 Controlling reactors WESTING- HOUSE ELECTRIC CORP 11 Feb 1975 [19 Feb 1974] 5719/75 Heading G6C A reactor control rod assembly comprises a control rod 10, a drive shaft assembly 20, a coupling 11, 21 for connecting the control rod to the drive shaft assembly, and co-operating radially projecting guide members and detent members connected to the drive shaft assembly for coupling and uncoupling the drive shaft assembly to and from the control rod. In the embodiment illustrated the detent member comprises a grooved cylinder 40 rotatably mounted on a drive shaft 27 with the groove formed so as to hold a pin member 41 mounted on the inner wall of a cylindrical member 23 in one of two axially spaced positions, one position creating coupling and the other creating uncoupling between the control rod 10 and the drive shaft assembly 20, the pin member 41 being movable from one position to the other as a result of lowering and subsequent lifting of the drive shaft 27. Engagement between the control rod 10 and the drive shaft assembly 20 is obtained by an expandable collet 22 integral with the cylindrical member 23 which is axially movable with respect to the drive shaft 27 against the biasing action of a spring 31. A rod-like plunger 24 forming the end of the drive shaft 27 and extending through the collet 22 is utilized to expand the collet 22 into mating engagement with the upper end 13 of the control rod 10 via grooves 11 in the latter and corresponding protrusions 21 on a plurality of resilient arms forming the lower end of the collet 22. Hence, the position of the plunger 24 relative to the collet 22 causes engagement or disengagement of the coupling. Lowering of the drive shaft 27 causes the pin member 41 to rotate the grooved cylinder 40 by the action of a cammed surface (of Fig. 1), the pin member 41 then being aligned with an axial groove in the cylinder 40 such that the drive shaft 27 is allowed to move in an upward direction relative to the collet 22. As shown on the r.h.s. of Fig. 2, the plunger 24 then expands the collet 22 effecting engagement of the coupling. In order to disengage the coupling, the drive shaft 27 is again lowered causing the pin member 41 to rotate the cylinder 40. However, this time the pin member is aligned with a groove having a shouldered stop 43 and upward movement of the plunger 24 is thereby prevented, as shown on the l.h.s. of Fig. 2.
