Abstract: 129,525. Edwards, T. J., (trading as T. J. E. Games Co.). Oct. 1, 1918. Card games.-A pack of 49 playing cards bearing representations of foodstuffs, fuel. and so forth, controlled under a rationing scheme, consists of 12 suits of four cards each, and a master card designated " Kybosh." Each card is printed at the top with an indicator name which is also printed small and sidewise at the top left-hand, and at the bottom right-hand corners. Some of the suits may be omitted from the pack or additional suits may be introduced The game is to secure tricks by oneself or by bluffing others into making tricks. Thus the caller may challenge another player for a card who, although possessing the card, may deny possession. The caller may then, if he thinks proper, call the Bluff by which the cards of the suit are placed on the table. The master card carries with it certain privileges, and when played is pooled with a card from each of the other plavers. The pool is shuffled and dealt out according to defined rules.

IPC: F23K3/14
Filed: 1949-06-16
Abstract: 734,261. Reciprocating screw feed. YOUNG, M. June 16, 1950 [June 16, 1949; Nov. 7, 1949], Nos. 16037/49 and 28401/49. Class 78 (1). Mechanism for conveying fuel along a channel 11 comprising a reciprocating screw member 10 arranged in the channel 11, and interengaging pin - and - guide means 24-23, one member of which is fixed relatively to said channel 11 for positively moving the feed member axially along the channel in one direction substantially without rotation in order to advance a charge of the material and for rotating the screw member whilst positively returning it axially in the other direction so as to unscrew said member from the charge. The screw 10, Fig. 2, in channel 11 is given an axial reciprocating movement by motor 45, the movement passing thereto through pinion 47, gear 48, crank 49, connecting rod 50, rocking lever 51 carrying pawl 54, ratchet 53, crank arm 20, and screw shaft 18 rotatable relative to crank arm 20. The stroke is varied by varying the length of engagement of pawl 54 with ratchet 53, the pivoted sleeve 55 serving to disconnect the pawl from the ratchet teeth during a portion of the movement and being actuated by handle 56. The axial reciprocating movement is converted into a rotationless forward stroke and a rotating back stroke by the engagement of fixed pins 24 and 24a in endless groove 23, the groove having axial portions 25 and helical portions 27 and being formed in piston extension 17 fixed to screw 10. The pins and slot are relatively interchangeable. Alternatively (Fig. 4), there may be outer piston 29 and inner piston 30 both arranged rotatable but non- axially slidable relative to screw shaft 18 between collars 33 and 34 formed rigid thereon. Outer piston 29 is axially slotted at 35 and inner piston 30 is helically slotted at 36, fixed pin 37 engaging simultaneously with both slots. Outer piston 29 is clutched to said screw shaft 18 by a one-way clutch formed of ratchet teeth 38 engaged by pawls 40,' which pawls slide in slots in said outer piston 29'and are pressed inwards into engagement with the ratchet teeth by annular spring 42. Inner piston 30 is similarly clutched to said screw shaft by a one-way clutch formed of ratchet teeth 39 and pawls 41 pressed inwardly by annular spring 42. In operation the whole device slides back and forth in channel 16, the inner piston 30 rotating clockwise and anticlockwise whilst the outer piston 29 remains rotationally static. On the forward stroke, shaft 18 is prevented from rotation by the engagement of clutch 38-40 with the outer piston 29. On the reverse stroke shaft 18 is caused to rotate by the engagement of clutch 39-41 with the rotating inner piston 30. Specification 666,686 is referred to.

Title: Improvements in and relating to cathode-ray tube systems, particularly for colour television
IPC: H04N9/26
Filed: 1953-06-12
Abstract: 747,101. Television. PHILCO CORPORATION. June 12, 1953 [June 14, 1952], No. 16237/53. Class 40 (3). In a colour television receiver in which the screen of the picture reproducing tube comprises a repeating series of (colour) fluorescent stripes deflecting means auxiliary to the normal vertical and horizontal deflecting means are provided adjacent the fluorescent stripes for deflecting the scanning beam on to stripes of predetermined colour under the control of a deflecting signal which is also employed to control the application of the corresponding colour signals to the beam modulating electrode of the tube. As shown in Figs. 1 and 2 the screen 22 of tube 12, which comprises a repeating series of stripes 32, 34, 36, 34 fluorescing in the colour sequence Red, Green, Blue, Green respectively, is backed by an electrode structure comprising an electron permeable layer 38 and, insulated therefrom, a series of interdigitated conductors 40, 42 which form the auxiliary deflecting means. The deflecting signal is supplied by a self-generating oscillator 54 operating at a frequency of 7 Mc/s. (in the case of a system employing U.S. standards) the output from the oscillator (A, Fig. 3) being supplied to the conductors 40, 42 over conductors 48, 50 and also, via buffer stage 94 and a phase control device 96, to a pulse generating circuit 92 which supplies pulse trains of the form shown at B, C and D (Fig. 3) to modulator units 86, 88 and 90 respectively. These units which are continuously supplied with separate signals representative, respectively, of the red, green and blue components of the image then operate to supply colour signal information to the control electrode 16 of the picture reproducing tube 12 in synchronism with the scanning of the appropriate colour stripes on the screen 22. Since in the sequence of the colour stripes there are twice as many green stripes as red or blue stripes (this sequence i.e. Red, Green, Blue, Green being employed to compensate for the fact that each conductor of the auxiliary deflecting means at one polarity is positioned between two other conductors at the opposite polarity resulting in the deflecting field between consecutive pairs of electrodes being alternately reversed) colour balance is achieved by making the red and blue stripes twice as wide as the green stripes.

Title: Improvements in Machines for Cutting Off Lengths from Metal or other Bars, for Surfacing, and for similar Operations.
IPC: B23B5/14
Filed: 1916-11-15
Abstract: 109,876. Taylor, Ltd., C., Taylor, G. B., and Broadfoot, W. H. Nov. 15, 1916. Lathes.-In a lathe for cutting off lengths from metal &c. bars, and for surfacing &c., the cutting speed of the tool in the rotary tool head is maintained constant bv changing the speed of rotation of the head in inverse ratio to the change of diameter of the work. The movement of the cutter is transferred to a switch controlling the actuating-motor through a cam shaped to produce the desired result. The tools are returned to their normal positions, while the speed of the main spindle is a maximum. The tools d<6> are secured to slides d<5> actuated by screws d<8> which are driven by worm gears, e, e<2> and toothed wheels g<3>, g<4> from a ring g freely mounted on the spindle d<2> and connected to a chain drive g<5>. If the ring g is rotated on the spindle d<2> while it is revolving and in the same direction, the tool d<6> is advanced. If it is held stationary, the tool retires, and if the ring is uninfluenced, i.e. rotates with the spindle d<2>, the tool is unaffected. The main driving shaft c<2> actuates the head d by a pinion c<3>, and a side shaft l by bevel gearing which actuates a speedgear wheel i<3> and a pinion i'. The wheel i<3> drives either of the three wheels j which by a clutch revolves a second shaft k, which is chain geared to the ring g. Disengaging the clutch j<2> leaves the shaft free. The rotation of k rotates wheels k<3>, k<4> and a screw m which engages a screw box n driven from the pinion i<4> by means of a wheel n<2> and sleeve n<3>. The box n is connected to a rack which rotates a cam r to actuate a switch t. When the switch engages the bottom stop to produce maximum speed, it is held by a catch bar v while the cam r moves back to normal position again with the cutting tools fully retired. The bar v is then released by a hand lever v<3> connected to a brake annulus w, or automatically. In the position shown. the ring g is being rotated and the tool slide d<5> is moving inwards. When the tool d<6> reaches its inmost point, the lever x is actuated to disconnect the clutch j<2> from the. speed gear and connect it with the brake annulus w to hold the shaft k stationary to retire the tool. The lever v<3> is then moved to the left to disconnect w and release the rod s. The tool and cam now become inoperative until the clutch j<2> registers again with the speed-gear wheels.

Filed: 1944-09-01
Abstract: 584,528. Dry-shavers. HARSHBERGER, R. P. Sept. 1, 1944, No. 16697. [Class 131] A power-driven razor comprises an elongated casing 10 having at the end 12 a spring motor 13 or other driving means which rotates a shaft 57 to impart a gyratory movement to the end 15 of the casing where there is a support 11 for the reciprocating cutting blade 70. Rotation of the motor housing 12 in relation to the barrel 14 winds up the spring of the motor 13 the outer end of which is fixed at 20 to the sleeve 21 of an internal ratchet 22 and the driving end is connected at 23 to the prime shaft 24, a pawl 27 preventing unwinding. The wheel 33 internally geared at 34 passes the slow rotary movement of the shaft 24 into a gear cage defined'by the bearing plates 26, 28 and spacing posts 29 where a series of coacting gear wheels and pinions increase the speed so that the last pinion drives the shaft 52 at a greatly increased speed. The flattened end of the shaft 52 engages at 56 with the tubular shaft 57 and a leaf spring 58 with a weight 60 having an inset braking plug 61 is secured to the shaft 57 near the cutting head by pins 59. An idler wheel 64 in loose contact with the pin 62 and mounted on the collar 66 attached to the shaft 57 ensures that the shaft maintains its true axis of rotation. The head 15, cap 71, blade 70 and bed 69 gyrate as a result of the centrifugal force of the rotating weight 60. Two leaf springs 76 connect diagonally opposite corners of the bed 69 to the end bars 77 of a guard and float the guard with respect to the cutting blade. The springs 76 yield only in the direction parallel to the cutting edge 70 and the face engaging guard members 78 so that the gyratory movement of the head 15 is translated into straight line reciprocatory movement in a directional parallel to the cutting edges. The blade 70, cap 71 and bed 69 are operatively and detachably secured to the head 15 by the screw 75 and the shaft 57, weight 60 and roller 64 may be removed as a unit.
