Filed: 1965-04-29
Abstract: 1,160,543. Razors. WILKINSON SWORD Ltd. 22 April, 1966 [29 April, 1965; 22 July, 1965], Nos. 40110/68 and 40111/68. Divided out of 1,160,542. Heading B4B. A shaving unit 10, Fig. 4, is made of plastics material in which a blade 10a is moulded so that its cutting edge 10b is pre-fixed relative to the guard surface 10c. The unit 10 is provided with a groove 10e mating with a projection 11b, Fig. 6, on the seat 11a of a handle 11 and with a step 10# which abuts against a step 11c at the rear end of the seat 11a. The unit 10 is held on the seat 11a by means of a spring-influenced pivoted clamp 12. The unit 10 is provided with channels 10d to facilitate rinsing the exposed portion of the blade after use. The unit 10 may be manufactured with more than one relative setting of cutting edge to guard surface, a marking being provided to indicate the particular code setting. Further, the guard surface may be treated to provide it with a predetermined coefficient of friction. In a modification, the shaving unit 30, Fig. 10, comprises a blade 30a, a keyway 30b and pairs of forward and rearward projections 30c, and 30d, and the handle 32, Fig. 11, comprises a head 32a having projections 32b. The shaving units 30 are stored in a dispenser 31, Fig. 8, and to withdraw a unit, the handle head 32a is pushed downwardly over that unit which is at the left hand end of the dispenser until a spring-loaded detent 33 in the head 32a is depressed by contact with the upper edge of the unit. After further downward movement of the head 32a, the detent 33 clicks into position in engagement with the keyway 30b to secure the unit in the head so that the unit can be withdrawn by upward movement of the head. A spring 35 in the dispenser then moves the next unit 30 into the withdrawal position. To return a used unit 30 to the dispenser, the head 32a with the unit fixed therein is fed into the right hand end of the dispenser. The engagement of the projections 32b on the head 32a with cam surfaces 31a on each wall 31b of the dispenser together with the engagement of the lower end of the unit 30 with a step 31d in the base of the dispenser cause separation of the head 32a from the unit 30 which is retained by the abutment of the rearward projections 30d with the underside of the flange 31b1 on the side walls 31b. During the movement of the used unit 30 into the dispenser, keys 31e formed in the inside faces of the side walls 31b are depressed and then return after sufficient inward movement to retain the unit in the dispenser.

Abstract: 936,656. Pulse circuits. TELEFUNKEN G.m.b.H. Dec. 3, 1959 [Dec. 3, 1958], No. 41057/59. Class 40 (6). A relaxation oscillator having a saw-tooth relaxation characteristic 1 is synchronized by saw-tooth pulses 5, the slope of the forward flank of which is of opposite sign to that of the characteristic 1. The nominal natural frequency of the oscillator is such that the rear flank 6 intersects the relaxation line at the natural transition point. As shown, frame synchronizing pulses 9 for a a television receiver are obtained from the separator stage 8 via a multiple integrating circuit 7. The line synchronizing pulses 18 are removed by means of a biased diode 10. Waveform 9 drives valve 12 into grid current, charging capacitor 11 and cutting-off the anode current until capacitor 11 has discharged via resistor 15, giving waveform 19. Valve 12 passes anode current during the hatched portion of waveform 19 providing a negative going sawtooth waveform 21 at the anode which is used to synchronize a blocking oscillator or multi-vibrator type of time base generator 14. The relaxation waveform 1 of the oscillator 14 is shown in Fig. 2; the free-running frequency being adjusted so that the transition point 6, when free-running, coincides with the centre of the trailing edge of the synchronizing pulse 21.

Abstract: 960,252. Bottle closing apparatus. G. BODMER. Nov. 30, 1960 [Dec. 1, 1959], No. 41192/60. Heading B8T. A bottle cap 6, Fig. 4, having a surrounding metal ring 38, is secured to a bottle neck by compressing the ring 38 radially beneath a bulge 39 on the bottle neck. The cap is applied by a plunger device 2, Fig. 1, having a member 14 attached to a reciprocating plunger and carrying an outer sleeve 1 with a pin 10 therethrough which passes through slots 13 in the member 14 and slots 22, 29, in a spring-loaded sleeve 20 and plunger 28 carried by the member 14. A cap 6, which is inserted into member 1 through a radial slot 7, is pushed on to the bottle top, entering through opening 8, by the plunger 28. On further movement of the bottle upwards, the plunger 28 contacts the pin 10 so that the parts 28, 1 move upwards together with the bottle. When the upper surface of the plunger head contacts the sleeve 20, sectorshaped fingers 34 are moved upwards by sleeve 20 relative to a conical surface 17 on the member 14 and are forced inwards to compress the ring 38 on to the bottle neck at a position below the bulge 39. The cap may be of synthetic plastic. The plunger head 30 contacts the sleeve 20 through a spring-washer 31 which allows for variations in size of the bulge 39.

Abstract: 1294573 Welding by fusion NIPPON KOKAN KK 3 Sept 1970 [6 Sept 1969] 42135/70 Heading B3R Intermittent tack welding is effected by feeding a workpiece in a given direction past an arc welding head which is reciprocated in parallel with the workpiece feed path at a speed slower or faster than the workpiece feed speed, the welding arc being struck by limit switches or timers when the head is moving in the given direction of the workpiece. As shown in Fig. 4, for reciprocation the head is fixed to a member 15 having a slot engaged by a slider 14 fixed to a chain 13 wrapped around vertical axes sprockets 11, 12. The member 15 is guided by rails to reciprocate in a path parallel to the workpiece feed path.

[Also in Groups XV and XXX] Relates to apparatus for wrapping cylindrical objects which are rolled by bands 17, 18, 19, Figs. 1, 2 over an adhesive applying device 16 and then over a wrapper pile 33. The wrapper pile 33 is located in an opening in a table 1 and a feed conveyer belt 2 is located at right angles to the table, a pusher plate 3 being positioned for moving the objects from the belt 2 to the table 1. As shown the pusher plate 3 is operated by a pneumatic cylinder 4 and a spring-loaded stopping plate 5 at the end of the belt 2 is actuated by a pneumatic valve 7. Positioned at the other end of the belt 2 is a short conveyer belt 8 driven through a releasable clutch 9. When an object is fed on to the table it passes over a flap 10 which operates a valve 11 to cause the clutch 9 to start operation of the belt 8. When the object meets the plate 5, the valve 7 causes the clutch 9 to release and simultaneously actuates the pneumatic cylinder 4. Three discs 16 in a tank 13 protrude through slots 14 in the table to apply adhesive to the objects. The wrapper pile 33 is carried on a tray 30 supported by nuts 31 on threaded spindles 32 which are connected through reduction gears 34 and by means (not shown) to a spindle 39 which carries a feeler 40 and a weighted arm 41. The feeler 40 is actuated by passage of an object to rotate the spindle 39 and thus lift the tray 30. A cord 43 positioned above the top wrapper of the pile 33 along the edge thereof is guided over pulleys 45 into a tank 46 containing adhesive and effects a continuous application of adhesive on the edge of the wrapper.
