Title: Improvements in or relating to reflex light reflectors
IPC: G02B5/128
Filed: 1947-06-12
Abstract: 636,956. Coated fabrics. MINNESOTA MINING & MANUFACTURING CO. June 12, 1947, No. 15564. Convention date, Dec. 4, 1946. [Class 140] [Also in Group XX] A reflex reflector comprises a plurality of transparent spheres partially embedded in a layer comprising a transparent body, a finelydivided dark pigment and a highly reflective metallic flake pigment, the metallic flakes being so oriented adjacent the spheres and the relative proportions of the layer substances being so chosen that the reflector appears dark in diffused light but acts as a reflex reflector in directed light. As described, the pigments are carbon black and aluminium powder pigment. The reflector shown in the Figure is made by first sizing a paper backing 21 with a layer of polystyrene in xylol and, after drying, with a thin layer of polyvinyl butyral in an organic solvent. After drying, a reflecting coating 22 consisting of a phenolic base varnish and an aluminium flake pigment is applied. This is followed by a binder layer 23 consisting of a solution of thermosetting urea-formaldehyde resin with blown castor oil in an organic solvent, together with an aluminium flake pigment and carbon black. Before this layer has set the spheres 24 of glass or resin are embedded therein. After setting the backing 21 may be removed and used again. The layer 22 may be omitted or replaced by aluminium or tin foil' or by chromium-plated steel. The spheres may be covered by a transparent coating with a flat front face. The beads may be coloured.

Title: Logic unit
IPC: H03K19/088
Filed: 1972-04-05
Abstract: 1360136 Transistor logic circuits B M MANSUROV V I GORYACHEV V V ILINSKY I D YAKUSHEV V Y KONTAREV G G AKIMOVA and V N FILATOV 5 April 1972 15753/72 Heading H3T AND gates comprising transistors 1, 2 which each receive true and inverse inputs 5, 6 and 7, 8 at base and emitter respectively, are connected to a multi-emitter OR gate 3. T3 drives an amplifier 4 whose output is fed back to T1 base to effect a latching action. When the clock pulse at 19 is low, T1 is able to conduct to establish the latching feedback. When the clock pulse is high T1 is off, and T2 is enabled to respond to an input 8 to its emitter. If input 8 is low, T2 and T3 conduct to make amplifier 4 input low and its output high, so that the state of the latch is unchanged and is maintained by T1 when the clock 19 goes low again. If input 8 were high, the latch would change state, and T1 would not conduct even when the clock goes low again, so that the new low output 10 would be maintained. A similar AND/OR circuit 18 has in addition an inverter stage whose output 16 provides the latching feedback, which in this case goes to T2 emitter. In this case therefore, the latching feedback is effective during high portion of the clock signal, T2 being held on thereby, and is ineffective during the low portion. Hence units 17, 18 are alternately enabled to respond to their inputs 5 (to 18) and 8 (to 17), and as each of these inputs is the output of the other unit, a divide by two action is effected. Various signal input networks to T1 and T2 bases are possible (Fig. 6, not shown) using combinations of resistors, capacitors, and diodes.

Abstract: 217,765. Heninghem, C., and Newman, C. P. June 18, 1923. Dirt, excluding; stops, adjustable. - The spindle and stuffing box of a screw-down valve are provided with a protecting cover which serves also as an adjustable stop to limit the maximum opening of the valve. The head portion u of the valve is provided with a screwed collar a having a gap a to receive a bolt g, Fig. 4. The protecting cover, Fig. 3, is provided with internal threads to screw on to the collar a, and with two or more vertical slots k. The cover is adjustable vertically so that the maximum opening of the valve is limited by the engagement of the shoulder h, Fig. 2, with the part j of the cover. A washer b, Fig. 4, is secured to the upper side of the collar a, and supports a small bolt g so that it may slide radially. When the bolt is pressed inwards, it allows the cover to be rotated, but when the bolt is drawn outwards into one of the slots k, it prevents such rotation. When in its outer position, it is retained by a catch m, Fig. 5, carried by a loose washer e which pivots on the body by means of lugs engaging in slots o, Fig. 2. A spring f retains the catch in its upper position, from which it is released by hand as shown.

Title: Improvements relating to machines for running together pairs of segmental gears
IPC: B23F19/02
Filed: 1953-06-09
Abstract: 731,766. Gauging toothed gears. GLEASON WORKS. June 9, 1953 [June 18, 1952], No. 15825/53. Class 106 (2). [Also in Group XXIII] A machine for gauging pairs of segmental gears G, P (i.e. gears in which by omitting one or more teeth from one or both gears of a pair or by other means the gears cannot rotate continuously in mesh) comprises a drive spindle 14, Fig. 1, journalled in a support 12, driven spindle 15 journalled in a support. 13, means for adjusting the two supports relatively on a base 11 to bring the gears which are mounted on spindles into desired running position, a reversible motor 16 connected to the drive spindle, means for resisting rotation of the driven spindle, and means rotatable in time with the rotation of one of the spindles for operating a control to reverse the motor at selected positions of the latter spindle. The motor 16, which is of hydraulic type, comprises a wobbler plate 44, Fig. 6, mounted on its drive shaft 45 and acted upon by a plurality of pistons 43 reciprocating in cylinders to which hydraulic pressure is supplied under the control of an annular valve 47 actuated by an eccentric 46 on the shaft 45. Hydraulic pressure to the motor is supplied by a pump P through a solenoid-actuated valve 53 and shuttle valve 56 which is alternately positioned at opposite ends of its stroke so as to reverse the direction of fluid supply to the motor and thereby the direction of rotation of the latter. Reciprocation of the shutter valve is effected by hydraulic pressure supplied alternately to its opposite ends by a reversing valve 57 carried by the support 12. The core of the latter valve is rotated between its two positions corresponding to reversal of the motor by the coaction of stops 71, 72, Fig. 3, adjustably mounted in a slot in the periphery of the spindle 14 with fingers 68, 69 on the core. The valve 53 is actuated to start the machine by closing a switch 77 and depressing a lever which closes a second switch 42 and applies a band brake to spindle 15. The support 12 is adjustable transversely of the spindle 14 by a screw 21, and the support 13 is adjustable vertically by a screw 25 on a column 26 rising from a slide 24 which is similarly adjustable transversely of the spindle 15. The support 12 may be moved rapidly to and from operating position by power means, with which may be associated means as described in Specification 657,499 for obtaining a pre-selected amount of back-lash between the gears. The latter means comprise the journalling of the spindle 14 in a carrier 27 which is pivoted to the support 12 and when floatingly held permits the gears to be run together by hand, any eccentricity of the gears being shown by a dial indicator 32; when used in this way, a switch 33, Fig. 6, is opened automatically to prevent power operation of the machine. If desired, a constant drag brake may be provided for imposing a pre-determined load upon the spindle 15.

Abstract: 624,150. Windscreen cleaners. TRICO PRODUCTS CORPORATION. June 17, 1947, No. 15983. Convention date, June 24, 1946. [Class 138(i)] In a windscreen wiper where relative angular displacement between the wiper blade and actuating arm enables the blade to lie along the edge of the windscreen in the parked position, the blade is urged towards a centralized position by leaf springs arranged on opposite sides of the blade, the springs having parts co-operating with the actuating arm whereby they are prevented from urging the blade beyond its central position. As shown, a hook-shaped fin 4, pivotally mounted at the apex of a triangular opening 5 in a wiper actuating arm 2, supports a wiper blade 3. Angular displacement between the blade and arm is limited by stop flanges 8. Spring leaves 10, fitted to each of the stop flanges by rivets 9, bear against or lie adjacent to opposite sides of the wiper blade and provide a restoring force for aligning the blade and arm. Extension ears 11 of the spring leaves, bearing against the outer side faces of the actuating arm, prevent either spring from tending to urge the blade beyond its central position. Specification 512,138 is referred to.
