Title: Improvements in or relating to cycle pedals
IPC: B62M3/02
Filed: 1955-07-26
Abstract: 813,047. Cycle pedals. JONES, W. E. June 28, 1956 [July 26, 1955], No. 21521/55. Class 136(2) Means for facilitating the engagement of a foot in a toe clip 12 of a cycle pedal comprises a rear lever projection A fitted to the back of the pedal so that it forms a lever to turn the pedal by the foot into position for the foot to move forwards out of engagement with the lever projection into engagement with the toe clip. The lever projection A is formed of sheet metal and is U-shaped in cross-section. One arm 2 is adapted to bed against a transverse plate 3 of the pedal. A hook 4 on the arm 2 engages over one edge of the plate 3. A second arm 5 curves away from the arm 2. A spring clip 6 having a straight length 8 is engaged inside the bend 9 of the lever projection A and the hooked shaped ends 7 of the clip are sprung over the other edge of the plate 3 between the usual serrations on that edge. Lugs 11 are pierced out of the arm 2 to form pockets 9a for alternatively anchoring the spring clip 6. A toe clip may be similarly fixed on the pedal.

Title: Improvements relating to photographic masking
IPC: G03B27/72
Filed: 1961-06-15
Abstract: 928,360. Copying by scanning. LOGETRONICS Inc. June 15, 1961 [June 17, 1960], No. 21683/61. Class 40 (3). In photographic masking apparatus comprising a cathode-ray tube producing a spot of light which scans a transparency to print an image thereof on a photosensitive emulsion at least a part of the light passing through the transparency falls on a photo-electric detector, the output of which controls the spot brightness through a feedback loop having an adjustable range of output. In an embodiment for producing colour separation plates a portion of the light from the cathode-ray tube 10 passes through the transparency 28 and a filter 40 to a photo-sensitive emulsion 34 and the remainder through a filter 42 to a photomultiplier 38. Filters 40, 42 are substantially complementary and a plurality of such pairs of filters are provided on the drum 44 for use in making a plurality of separation plates. Either the photomultiplier 38 or the amplifier 46 has a logarithmic characteristic and the output of amplifier 46 is passed through a masking control 48 and applied via a cathode follower 60 as a negative feedback to the control grid of tube 10. The grid of cathode follower 60 is connected to a voltage limiter comprising a double diode 70, biased in accordance with desired limits of highlight and shadow masking set on potentiometers 90, A, B, C and 86 A, B, C respectively. The overall degree of masking is set on potentiometers 50, A, B, C. Filter drum 44 and switches 52, 74 and 82 are coupled by means 98 for simultaneous change over for making the plurality of separation plates. Specifications 713,285 and 790,509 are referred to.

Title: Glass coated electrical steel sheet and articles therefrom
IPC: C23D11/00
Filed: 1967-05-11
Abstract: 1,130,286. Coating with glass. WESTING- HOUSE ELECTRIC CORP. 11 May, 1967 [9 June, 1966; 2 Sept., 1966], No. 21856/67. Heading C1M. [Also in Division H1] Glass-coated steel sheet for bonded core structures is produced by coating an oriented electrical steel sheet of iron-silicon alloy with a magnesium-base compound, annealing the sheet at an elevated temperature at which it reacts with the coating to form an adherent layer of complex magnesium-base compounds on the surface of the steel sheet, fusing a thin coating of a glass having a low coefficient of thermal expansion on the layer of magnesium-base compounds at a temperature of from 700 to 850 C., or to 925 C. and cooling the glasscoated sheet whereby the glass coating contracts less than the steel sheet and maintains the steel sheet in tension. The coated steel sheet is then wound to core configuration to a temperature of from 700 to 825 C. while weighted to bond adjacent turns of the core structure to each other. Coatings of glass are of the order of 0À1 mil to 0À3 mil. A coil 12 of steel sheet 14 having mill coating of complex magnesium base compounds is passed over a coating roller 18 immersed in a glass slip 21 in a tank 19 and up between spray heads 24 to give a glass coating. Either method of coating may be used alone. Rollers 28 remove excess glass slip and the glass coated sheet then passes through an induction coil 32 to fuse the coating, through cooling plates 34 and is re-wound on spool 44. In an alternative apparatus the coated slip is dried by infra-red lamps and passed through a tube furnace. A number of glass composition examples are given from the following glass ranges in weight percentages: (1) ZnO 31-60; B 2 O 3  11-33; PbO 10-44; SiO 2  8-14; (2) P 2 O 5  60-70; MnO 10-14; Al 2 O 3  9-12 and at least 5% from the following ZnO 0-8; SiO 2  0-10; Na 2 O 0-3; CaO 0-7; MgO 0-4; BaO 0-5 with optionally As 2 O 3  up to 1; V 2 O 5  up to 1; B 2 O 3  up to 5 ; Fe 2 O 3  up to 5; (3) SiO 2  45-55; B 2 O 3  10-14; Al 2 O 3  5-7; Na 2 O 8-15; BaO 10-16; CaO 5-8; P 2 O 5  up to 4; MoO 3  up to 2.

An animal figure toy is actuated by a clockwork mechanism which imparts a snapping movement to the jaws of the figure and operates a noise-producing device, the mechanism being stopped when a member is placed between the figure's jaws. As shown, the flyweight 19 of a clockwork mechanism 11 is connected by a link 21 to a pin 22 which engages the body 30 of the figure and reciprocates in a slot 23 in the base 10. An extension of the pin 22 operates a bellows 24 connected to a whistle 26 and trumpet 27. A lower jaw and front leg portion of the figure are formed as a unit which is pivoted to the body and base at 33 and 32 respectively and has a projection 35 which engages a projection 36 of a pivoted upper jaw 37. The reciprocating movement of the body of the figure causes the jaws to open and close but on placing a representation of a bone 39 between the jaws, movement of the figure and clockwork mechanism is stopped. In a modification, Figs. 5, 6 (not shown), a bellows squeaker is located in the body of the figure and the clockwork mechanism is also controlled by a stop arm movable by means of a cord attached to the " bone."

A helicopter is provided with means for reciprocating its rotor upwardly and downwardly. As shown in Fig. 1, a man-powered helicopter has rotary wings 70 mounted on a shaft 56 reciprocable by a cable 99 leading a slider 46. The slider 46 is mounted on a tail arm 29 and is connected by arms 45 to shoulder bars 52, so that as the pilot raises and lowers his body, e.g. by running up and down rungs 26, the rotor is raised and lowered. Arms 90, 91 each engage a spiral guide 94, 95 at one end, and are fixed to a freewheel 88, 89 on the rotor shaft 56 at the other end, so that as the rotor shaft reciprocates it is rotated. The rotor is raised initially by pulling on a cable 57. The rotary wings (Fig. 4) comprise fabric panels 87 secured to spars 68 and ribs 86, the spars 68 being pivotally mounted at 71 in a framework 64. Preferably further hinges are provided at 71 to allow the wings to be folded (Fig. 9, not shown). Arms 73 (Fig. 1) rising from the inner ends of the spars 68 are connected by elastic bands passing through a horseshoe 77 movable vertically by a cam 81 for collective pitch control. The rotor hub 61 is connected to the shaft 56 through a rubber block (Fig. 6, not shown) so that it may be tilted by a disc 60 engaging ports 109 on a disc 108 tiltable by the control stick 107. Yaw control is effected by a tail rotor 33 driven by the cable 99 through a freewheel, a pulley 36 and a clutch operable through a cable 104. In a modification (Fig. 10, not shown) the helicopter is powered by an engine rotating the rotor through splines on the rotor shaft 56, and reciprocating it by hydraulic transmission to a double-acting hydraulic ram.
