Title: Improvements in or relating to the shaping of the edges of spectacle glasses
IPC: B24B9/14
Filed: 1961-03-29
Abstract: 973,642. Grinding; lathe details. G. LISSAC. March 29, 1961 [April 9, 1960], No. 11591/61. Headings B3D and B3T. A machine for trimming the peripheral edge of a plane-concave or -convex, or concavoconvex lens 60 comprises a supporting frame 1 carrying a fixed support for a rotary tool 8, a lens carrier 30 having means 54 for rotatably holding the lens with its peripheral edge directed to the working face of the tool, a template 58 mounted on the lens-holding means with its edge directed to a stop 18 axially aligned with the rotational axis of the tool 8, and a parallel linkage 37 connecting the carrier 30 to the frame 1 permitting movement such that the axes of rotation of lens and tool remain parallel and the peripheral edge of the lens to be ground, when engaging the working face of the tool, is positively maintained in register with a predetermined peripheral portion of the working face. The lens 60 is held between resilient supports at the adjacent ends of a divided shaft 54 which is rotatable within bearings in a carriage 30 mounted on a slidable table 2 by links 32 which form a parallelogram, lateral movement of the slide 2 being effected by a hand wheel 21. Thus movement of the axes of rotation of the shaft and lens remain in parallelism with the axis of a tool 8, rotatable in a fixed bearing block 4 by a motor 9. The lengths of the links 32 are adjustable to suit the lens by selectively engaging pins 37 in holes 36 in the ends of the links. The movement of the carriage 30 towards and away from the tool axis whilst grinding the edge of a non-circular lens is determined by the contour of the lens periphery until a template 58 contacts a stop 18 carried by an arm 16 of an adjustable member 12 which is clamped by a wheel 20 after the required setting has been obtained by a micrometer 14. Disengaging movement of the lens holding shaft 54 is effected by a rack 48 on a sleeve 47 which moves the shaft axially when a lever-operated sector 49 is moved against the action of a spring-loaded plunger 61 located within the carriage; the lens may be rotated manually with the shaft by a wheel 66 and elongated pinion 65 which drives a gear-wheel 56 carried by a sleeve 52 in sliding and driving engagement with the shaft extension 57. The grinding tool may be grooved, Fig. 3, to form a rim, or may itself carry a rim for grooving the lens periphery.

Abstract: 352,543. Knitting-machines. HOLMES, H. H., LEEDHAM, L. H., and WILDT & CO., Ltd., Adelaide Works, Leicester. April 11, 1930, No. 11603. [Class 74 (ii).] To increase the space available for the passage of a wale thread guide 12 between adjacent needles, the heads of alternate needles are separated more widely in a radial and for circumferential direction than when in the knitting position. One method of doing this is to crank the stems of the respective needles 14 either forwardly or backwardly. Certain sinkers may be provided with lateral projections 17 which deflect the respective needles. Alternatively certain needles may be pressed out of line by a notched wheel or the bottom of certain needle tricks may be out of line with others, so that when the needles are elevated their heads are not in line. Specification 331,586, [Class 74 (ii), Knitting &c.], is referred to.

Motor Car & Railway Carriage & Wagon Builders ; 200, Kartouzska, Smichov, Prague) April 18, 1935, No. 12063. [Class 108 (i)] In streamline vehicle bodies the wheel housings for the front and rear wheels are incorporated in, and form part of, the supporting framework. The wheel housings 4, 5 are as shown, flat half cylinders and are joined by lateral frame members 6 while the front housings 4 are connected by a front transverse frame member 7 and the rear housings 5 by frame members 8, 9. The front housings are connected by a partition 10 having an extension 11 while the rear housings are also cross connected by partitions 12, 13. These partitions together with a cross member 14 serve to strengthen the frame laterally and also serve to subdivide the body into spaces for the engine, passengers and luggage. The partition 10 and extension 11 are provided with frame members 15 which are connected to the upper lateral from members 16 which continue down as at 17 to the rear wheel housings 5.

Title: Time limit relay
IPC: H01H50/88
Filed: 1938-04-22
Abstract: 495,948. Electromagnetic switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. April 22, 1938, No. 12125. Convention date, Nov. 20, 1937. [Class 38 (v)] A switch 7 controlling a releasing circuit K1, K2 is operated a certain time after the closing of the energizing circuit A1, A2 of an electromagnet 1 by the step-by-step rotation of a ratchet wheel 2 driven by the armature 11 of the electromagnet. At the end of this time when the circuit A1 A2 is de-energized the ratchet wheel 2 returns to its original position under the action of a spring 21, a pawl 3, which has held the wheel 2 against this backward rotation, being lifted out of engagement with the wheel by the armature 11 when it reaches the final rest position shown. When the lines A1 A2 are first energized, the armature 11 is attracted and drives the ratchet wheel 2 forward. A pivoted arm 51, biassed by a spring 53, follows the armature 11 and turns an induction disc 5, controlled by a magnet 56, so that an arm 61, driven by pins 54, 55 on the disc, closes contacts 61, 62 short-circuiting the magnet 14. The armature 11 is thereby released but before it has reached its final resting position, the pin 55 will have re-opened the contacts 61, 62 and the armature will be again attracted. The step-by-step driving of the ratchet wheel 2 continues until the switch 7 is actuated by an arm 22 on the spindle of the wheel 2. Contacts 73 are then opened preventing the short-circuiting of the magnet 14, so that the armature 11 remains at rest, attracted, till the lines A1, A2 are de-energized.

Abstract: 1,138,972. Semi-conductor switching circuits. ARROW ELECTRIC SWITCHES Ltd. 22 March, 1966 [30 July, 1965], No. 12485/66. Heading H3T. In a circuit for energizing a load 35 a predetermined number of times, each "on" period is determined by timer 41, each "off" period by a further timer 42, timers 41, 42 being operative alternately for a period determined by a third timer 43. As described, the sequence is initiated by closing switch 12, contacts 36 of which complete a circuit between a power supply 37 and load 35. Contacts 11 of switch 12 energize the first timer 41, capacitor 52 charging via variable resistor 50, until uni-junction transistor 60 breaks down, triggering thyristor 38 and energizing relay 25. Contacts 34 of relay 25 disconnect the load 35 whilst contacts 30, 31 initiate operation of the second timer 42 in which capacitor 55 is charged via the variable resistor 53. When uni-junction transistor 70 breaks down, thyristor 39 is triggered, its anode voltage being passed via capacitor 76 so as to turn off thyristor 38, releasing relay 25 and re-connecting the load 36. This sequence continues until capacitor 49 of timer 43 has charged sufficiently to break down uni-junction transistor 73, energizing thyristor 40 which turns on diode 77 thus preventing further operation of timer 42 and terminating the sequence.
