Title: Improvements in and relating to mechanical toy construction sets
IPC: A63H13/00
Filed: 1937-12-17
Abstract: 507,642. Mechanical toys. PAVELY, D. A., and WILLIAMS, L. E. Dec. 17, 1937, No. 35044. [Classes 132 (iii) and 146 (ii)] Apparatus for the construction of working toys comprises a series of loose sheets, which may be secured together so that the sheets may be displaced with respect to each other by relative movement in their own planes but not as a bound book, comprising parts outlined and partially severed from the sheets, these parts forming all or the major parts for the construction of a prime mover and of mechanical toys to be driven thereby. A vaned wheel is built up of two discs 23, 24, Fig. 8, joined by concentric annular bands 25, with tongues engaging slots in the discs, vanes 8 are added similarly and the wheel is mounted on a spindle 3 carrying spacing elements and journalled in soft metal bearings 4, 5 with ears engaging slots formed in the walls. Sand falls from a hopper 7 through an opening 21 regulated by a valvo 10 to rotate the wheel, and falls into a scoop 11 the end of which is shaped to facilitate returning the sand to the hopper. The wheel can be viewed through a window which may be covered by transparent material. The wheel drives mechanical toys either through pulleys such as 9 which is composed of three discs 36, 37 38 secured to each other and to the spindle 3 or by a clutch device comprising a disc with teeth folded over to engage slots in a companion disc, A flying-chair toy is shown in Fig. 10, in which an arm 53 adapted to carry chairs is rotated on a vertical spindle 51 by a pulley 52 driven from the pulley 9. The column 46 is strengthened by internal discs 47a, 48a carrying bearings 49, 50 for the spindle 51. A circus toy is shown in Fig. 14, the spindle 54 rotating figures 59, 60 and actuating the parts 67, 69 by a cam and lever mechanism. In a modification, the prime mover has two wheels driven in opposite directions, and mounted side-by-side with separate spindles, one of which extends axially within the other. If the prime mover is made of sheet metal, the sand may be replaced by water. Those parts which form or support the rotating masses of the prime mover are of thicker material than the rest, and the sheets which may be of any light weight material are scored along the fold-lines. Parts may be held together by adhesive, clips or rivets-and parts such as spindles may be housed in pockets on the sheets. Specification 507,970 is referred to.

Title: Marking pencil
IPC: B43K29/06
Filed: 1956-11-19
Abstract: 798,767. Pencil sharpeners and point protectors. SPATZ, W. B. Nov. 19, 1956, No. 35291/56. Class 146(3) A marking pencil e.g. an eyebrow pencil, has a barrel containg a crayon which is axially slidable but not rotatable therein, means for feeding the crayon forwards in relation to the barrel, a cap attachable to the barrel, and a sharpener secured to the cap and rotatable therewith as the cap is mounted on the barrel to engage and sharpen the front end of the crayon. The crayon 73 is urged forward by a spring- mounted rod 68 so that its front end projects from a sleeve 30 fixedly mounted at the forward end of the barrel 20. A U- shaped spring 80 whose legs. 82, 84 are positioned in upper and lower grooves 56, 54 respectively of the sleeve 30 has a circular aperture in its intermediate part 86 through which passes the rod 68. When the cap 26 is removed from the instrument the part 86 of the spring tilts so that the edges of the hole therein bind upon the rod 68 and prevent it from urging the crayon 73 forward. Threads 104 on the cap 26 engage with threads 66 on the sleeve 30 to secure it thereto, as this is done a portion 106 of the cap engages a key member 94 slidable in the groove 54 and abutting the end of leg 84 and pushes it backwards. The free end of leg 82 is secured in the groove 56 so that the part 86 is then tilted in the opposite direction and the edges of the hole therein no longer bind on the rod 68 which urges the crayon 73 forward into engagement with the sharpener 28 in the cap 26. A ring 102 is fitted over the sleeve 30 to prevent accidental operation of the key 94. As the cap is rotated for screwing on to the sleeve 30 the front end of the crayon is pointed by the sharpener and the chips of crayon fall into the closed end 124 of the cap. The sharpener 28 is in the form of a truncated hollow cone having a slot, one edge 114 of which is the cutting edge of a portion 116 wedge-shaped in cross-section integral with and projecting into the interior of the cone to serve as the sharpening blade. The portion 116 extends substantially from the base of the cone to a point beyond the plane of truncation coincident with or just beyond the cone's axis. The axis of the sharpener is tilted slightly in relation to the crayon's axis so as to impose less strain on the crayon during the sharpening operation.

Abstract: 410,889. Producing designs by photography. FRANK, T. K., 10, Mile End Road, South Shields, Co. Durham. Dec. 13, 1932, No. 35326. [Classes 98 (i) and 98 (ii).] Designs are produced by moving a sensitive surface relatively to an apertured screen having one or more slits above which are mounted a number of carriers which are reciprocated or oscillated in planes adjacent to the screen and which carry devices for modifying the light, e.g. perforated or indented masks, photographic negatives or diapositives, or transparent carriers on which opaque articles are placed. In the apparatus shown, the sensitive surface is carried on a roller below the slit c, Fig. 1. Above the screen a are seven carriers j, p, q, t, t<2>, rand s performing various reciprocating movements under the influence of cams u<1>, u<2> and a crank k, driven by an electric motor h which also drives the roller carrying the sensitive surface. In a modified form, the sensitive surface is carried on a roller d, Fig. 6, below a slit c over which moves a shield y having a slit y<1>. The shield is carried by an arm x, pivoted at x<1> and having a pointer at the opposite end which is moved by hand over the outline of a design carried by a roller d<3> driven synchronously with the roller d. Specification 382,729 is referred to.

Title: A press for moulding powdered or granular materials
IPC: B30B11/02
Filed: 1927-12-30
Abstract: 308,957. Haddan, R., (Steatit Magnesia Akt.-Ges.). Dec. 30, 1927. Presses, mechanical.-In a press for producing solid bodies from ceramic and like powdered materials employing an upper movable and lower fixed pressing plunger and a movable matrix, the matrix and the movable plunger make a common downward movement for the main moulding operation, the plunger then continues to move while the matrix remains stationary for supplementary compression, the matrix then making a further downward movement over the fixed plunger, and the movable plunger being retracted to release the moulded article. In the illustrated form the pressing plunger 45 is stationary, while the other plunger 21 is moved vertically by the eccentric 7, and the cylindrical matrix 23 is also moved vertically by means of the cams 12, 13. A charge of material is delivered to the channel 22 of the matrix, following which the plunger 21 imparts an initial pressure by descending into the position shown in Fig. 5, while the matrix remains stationary. The matrix and plunger then move in unison to the position shown in Fig. 6, applying the main pressure to the material during the process. The plunger 21 then applies a final pressure while the matrix is stationary. Finally the plunger 21 moves upward again and the matrix continues moving downward to its lowest position, thus exposing the moulded article for removal as shown in Fig. 8. To assist in setting the operating mechanism in timed relation, the transmission shaft 9 is divided, the two parts being connected by a clutch 46. The cams 12, 13 reciprocate a crosshead 28, 29 to which the matrix is bolted detachably by a series of guided pillars 24, 39.

IPC: B60V1/02
Filed: 1959-10-20
Abstract: 965,748. Aircraft. HOVERCRAFT DEVELOPMENT Ltd. Oct. 5, 1960 [Oct. 20, 1959], No. 35593/59. Headings B7G and B7W. An aerofoil member has at least one surface provided with at least one supply port extending adjacent to and substantially parallel to the periphery of said surface, including means for supplying a gas to the supply port to issue therefrom and form a curtain of moving gas which, in operation, with the surface of the aerofoil bounds a space in contact with the surface whereby a cushion of pressurised gas is formed in said space on movement of the aerofoil member through the air. An aircraft 1 has wings 2 each provided with a peripherally extending supply port 3. Gas turbine engines 4 discharge air into ducts 5 which communicate with supply ports 3 to form curtains 11, which as a result of forward motion of the wing, are swept aft, as shown in Fig. 3, to form wedgeshape cushions of pressure gas which form an effective part of the aerofoil profile to influence lift. To increase stability of the aircraft, a further curtain 12 is supplied from a duct 14. In the embodiment of Fig. 6 a vertical stabilizer 25, e.g. a rudder, is formed on each surface with a peripheral supply port 29 each connected to a supply duct 30 through respective intermediate ducts 31, 32, provided with flap valves 33, 34. In operation, when rudder action is required, one or other of the flaps 33, 34 is opened by linkage 35 or 36 to cause gas to issue from the peripheral slots to form an appropriate wedge-shape cushion of pressure gas on the appropriate side of the stabilizer, to produce a rudder effect. An installation for a deltawing aircraft is described. Specification 894,644 is referred to.

Title: Automatic control system for a rotary well drilling rig
IPC: E21B19/08
Filed: 1966-08-10
Abstract: 1,115,977. Electric correspondence control systems. H. B. FULLERTON and B.J. FULLERTON. Aug. 10,1966 [Sept. 20, 1965], No. 35737/66. Heading G1N. The pressure exerted at the bottom of a well by a drill bit in a well-drilling rig is controlled in correspondence with the rotational speed of the drill bit so that their product is maintained substantially constant. As shown (Fig. 1), a drill bit is supported by blocks 9, 10, one support cable 11 terminating at draw works 12 with a brake 13, and the other support cable 3 terminating at an anchor 2 containing tension measuring means 1. The speed of rotation of the bit is measured by a tacho-generator 6. Signals from tensionmeter 1 and tachometer 6 are combined at 5 to provide automatic control of the brake 13 via actuator 19. The cable tension is converted at 1 into a hydraulic pressure which is conveyed to a control unit 5 to move the slider of a potentiometer 24 (Fig. 2) producing a voltage signal proportional to the total weight of equipment hanging freely from block 10, i.e. the bit pressure. This is utilised via an automatically balanced servo loop comprising difference amplifier 47 and servomotor 33 to position the slider 48 of further potentiometer 29 associated with calibrating potentiometers 35, 36 so that the position of slider 48 accurately represents the bit pressure. Servomotor 33 also drives slider 38 of potentiometer 31, the slider voltage representing bit weight, being shown at 37. Servomotor 33 also drives slider 49 of potentiometer 30, fed with the output signal from tacho-generator 6, whereby the signal at slider 49 represents the product bit weight x rotational speed (W x R). Power for the brake release actuator 19 is supplied through an AND gate 45 with four inputs: a. a pulse train generator 60 whose pulse width is adjusted at 61. This restricts the action of actuator 19 to a series of short impulses. b. the difference between the W x R signal on slider 49 and a preset W x R value on slider 52 of potentiometer 53, modified in accordance with the bit diameter by adjustment of rheostat 54. c. a signal at 56 representing the difference between the bit weight and a maximum permissible bit weight signal on potentiometer 43. d. a signal at 59 representing the rate of change of tension in the cable. If this exceeds a predetermined value no signal appears at 59. When all four signals are presented to AND gate 45 at the same time the actuator 19 releases the brake 13 to allow the drill bit to fall and continue drilling.

Title: Improvements in or relating to transmitting-receiving apparatus for short waves
IPC: H03D7/14
Filed: 1946-12-04
Abstract: 623,069. Radio apparatus. PHILIPS LAMPS, Ltd. Dec. 4, 1946, No. 35947. Convention date, July 23, 1943. [Classes 40 (v) and 40 (vi)] A short wave transmitting-receiving circuit comprises a two-valve mixing stage to which, for reception, incoming oscillations are applied in push-pull and local oscillations in parallel phase, the two valves also being adapted to generate oscillations for transmission from a dipole aerial. The Figure shows part of a transmitting-receiving circuit. For transmitting purposes, the switches S1<1>, S1<11> and S2 are in the position shown, and inductances L7<1> and L7<11> in the anode circuits of valves T<1> and T<11>, in conjunction with the anode-grid capacities provide positive feedback in the push-pull circuit so that oscillations are produced in tuned circuit L1<1>, L1<11>, C1 (which may be Lecher wires) which are transmitted by dipole aerial D<1>, D<11>. Condenser C7 in the parallel anode-cathode path prevents oscillations being produced in the parallel circuit. Modulation may be effected by switch S in the H.T. lead. For reception purposes, coils L7 are shortcircuited, and incoming oscillations are applied in push-pull via tuned circuit L1, C1 to valves T1, T<11> where they are mixed with oscillations in parallel phase to provide an intermediate frequency output in tuned circuits L4, C4 and L6, C6. The parallel oscillations may be supplied by local oscillator O which is coupled to coil L2 in the cathode lead. The parallel grid-cathode circuit consisting of coil L2, condenser C2 and a network constituted by the circuit L1, C1 and grid-cathode capacities, is tuned to the desired local oscillator frequency. Chokes L5<1> and L5<11> are included to prevent radio frequency oscillations in the intermediate frequency circuit. Instead of providing oscillator O, the parallel circuit of valves T<1> and T<11> may be made to oscillate by means of feedback provided by inductance L8 which may be inserted in the anode-cathode path by switch 52. An alternative arrangement allows for damping resistances to be included in one or other of the parallel and push-pull circuits, so that the desired mode of oscillation may be selected, and in this case condenser C7 and coil L8 are not required. The push-pull oscillations for transmission may alternatively be produced by a preceding pair of highfrequency amplifiers.
