Title: Improvement in and relating to expansible cutter for boring, reaming and like operations
IPC: B23D77/04
Filed: 1939-07-04
Abstract: 530,813. Boring-bars, boring-heads, reamers, &c. STAPLES, E. M. July 4, 1939, No. 19418. Convention date, July 15, 1938. [Class 83 (iii)] An expansible tool for boring, reaming &c. has a body provided with flexible tongues extending in a circumferential direction and provided at their free ends with cutting edges, wedging means being provided for adjusting the free ends outwardly and clamping means for securing the tongues against the wedging means. The body 10 is provided with circumferential saw-cuts 13 to form flexible tongues 12 carrying integral or separate cutters 20. The tongues are expanded outwardly by tapered pins 15 driven in axially, and are then clamped rigidly by radial screws 17 arranged singly or in axial rows. When considerable expansion is required the pins 15 may be replaced by wedges 31, Fig. 5, with rounded edges shaped to engage the recesses 32 throughout their axial adjustment, or the pins may be replaced by tapered screws. Flexing of the tongues 12 about their ends 27 during expansion increases the peripheral clearance angle of the cutters. The body 10 may be mounted by means of its central aperture 11 on a boring-bar supported at both ends, or may receive or be formed integral with a shank so as to constitute a boring-head. Specification 474,599 is referred to.

Title: Improvements in and relating to cyclometre-type registering mechanisms
Inventor: DRANSFIELD DESMOND
IPC: G06M1/16
Filed: 1960-06-01
Abstract: 931,502. Counters. ENGLISH ELECTRIC CO. Ltd. June 1, 1960, No. 19436/60. Addition to 828,684. Class 106 (1). A cyclometer-type register has transfer pinions normally biased to mesh with axiallymounted numeral drums but movable out of meshing position during a resetting operation. Drive to the first numeral drum 10 in an electricity meter is effected through a worm 19. The drive may include means for ensuring that the drums move instantaneously from one position to the next. Transfer is effected through pinions 15-17 formed of low-friction plastic material to the drums 11-13 of higher denomination. The pinions 15-17 are loosely mounted on a shaft 25 movable in slots and spring-urged so that the pinions are normally in mesh with the drums. The lowest drum is reset through the normal drive but the other drums are reset by hand, the springs 24 yielding to take the pinions 15-17 out of meshing position. The springs 24 may be dispensed with and reliance put on gravity.

Title: Improvements in the manufacture of articles of conductive rubber
Inventor: HANCOCK DOUGLAS CHARLES
IPC: H01B1/24
Filed: 1950-08-03
Abstract: Cable parts such as screens for cable cores, fillings between cable cores, or cable sheathing are manufactured by mixing p  together rubber containing compounding ingredients and conductive carbon black in an amount of volatile solvent sufficient to enable the required degree of mixing to be attained with only light working by agitation apparatus, evaporating the solvent and then extruding and vulcanizing the residual mixture.  In an example 100 parts of smoked sheet, 30 parts factice, 2 parts stearic acid, 10 parts of rubber processing oil, 10 parts zinc oxide, 1 part agerite white, 3 parts sulphur and 1 part dibenzthiazyl disulphide were masticated and then soaked in an equal weight of rubber solvent, 80 parts of acetylene black were dispensed in 7 parts of the same solvent and then the whole mixed. After standing 48 hours to enable the solvent to evaporate the mass was extruded and vulcanized.  The resulting product has a much lower resistivity than a product obtained in the normal way.

Title: Window operating apparatus
IPC: E05F11/44
Filed: 1953-07-14
Abstract: 742,681. Windows. WARWICK, H. F. Oct. 14, 1954 [July 14, 1953], No. 19585/53. Class 20(3). Sliding window operating apparatus comprises a manually operable lever mounted for rotation through an arc less than a semi-circle and rockable cam means, operated by an initial movement of the lever in either direction to slacken spring-pressed guides locking the window to its frame and operable on further movement of the lever in the same direction to jam against and rotate a surrounding member fixed to a spring balanced lever system moving the window. As shown, a vehicle window 1 has parallel vertical side edges 2 sliding in oppositely facing channel guides 3, which may be faced with felt 4, one of the flanges 5 of each guide being hinged to the web of the channel about a pin 6 and urged by a spring 40 into gripping engagement with the window edge. The lower edge of the window 1 is fixed in a yoke or frame 7 which carries a pair of vertically spaced pins 8, 9 slidable in a vertical slot 10 in a plate 11 fixed to the vehicle door frame, the pins being spring-pressed oppositely on the yoke 7 to apply a centring movement to the window 1 when the flanges 5 are freed. One end of a lever arm 12 is pivoted to the pin 9, the other end carrying a pin 13 slidable in a horizontal guide slot 14 in the plate 11, one end of a lever arm 16 being pivoted to the arm 12 on a pin 15 intermediate its ends. The lever arm 16 is rotatably mounted about a horizontal axis 17 fixed to the plate 11 and adjacent the opposite end which is connected by a cord 18 and pulley 19, or similar means, to a horizontally disposed tension spring 20 designed to counterbalance the weight of the window 1. A segmental drum 21 is carried by the arm 16 surrounding the axis 17 but leaving a slot 22 extending through about 70 degrees, and through which lies the operating handle 23. Within the drum 21, the handle 23 carries a segmental plate 29 which bears against the extremities of a cam plate 24, of roughly saddle shape, which has pins 25 and 26 engaging in short arcuate slots 27-28 formed in the lever arm 16, so that initial movement of the handle 23 in either direction rocks the cam plate 24 without moving the lever arm 16. This movement of cam plate 24 is transmitted, to move the flanges 5 against the springs 40, through a roller 39 on a push rod 30 pivoted to a crank 31 on a transverse shaft 32 having pins 33 engaging slots 34 in segmental plate 35 secured to the flanges 5. A compression spring 36 arranged between a collar 37 on the rod 30 and a fixed abutment 38 maintaining the roller 39 in contact with the cam plate 24. Further movement of the handle 23 causes the cam plate 24 to jam against the internal wall of the drum 21 to turn the lever arm 16 to move the window in either direction. A latch 43 fixed to the shaft 32 is arranged to engage in a slot in the upper pin 8 on the yoke 7 whenever the window is moved to its fully shut position, initial movement of the handle 23 to rotate the shaft 32 being necessary to release the latch.
