Title: Improvements in or relating to Electrically Operated Clocks and the like.
Inventor: ALLDIS WILLIAM
IPC: G04C3/027
Filed: 1916-08-21
Abstract: 108,729. Alldis, W. Aug. 21, 1916. Electric clocks.-Relates to the type in which the oscillation of a pendulum is maintained by an electro-magnet attracting an armature attached to the bob and in which hands are advanced by a ratchet and pawl, the ratchet-lever being operated by the pendulum. The circuit is normally open between a fiexible contact strip D and a stiff one beneath it, and a wiper C<2> hanging on the pendulum passes to and fro over a pallet C<3> upon the flexible strip; but when, from diminution of the amplitude, the wiper fails to pass the pallet, it thrusts the upper strip into contact with the lower. The pallet is made sufficiently extended to insure action. The ratchet-lever for driving the hands is an analed arm I resting against the pendulum rod A, and it has a pawl at the angle to drive the first of train of wheels H. Specifications 6216/97 and 20878/07 are referred to.

Title: Rib applying machine
IPC: A43D43/06
Filed: 1973-03-14
Abstract: 1420861 Boots &c PRIME MFG CO 14 March 1973 [12 June 1972] 12361/73 Heading A3B A rib-laying machine has work feeding and automatically adjustable guiding means for attaching a stitch-receiving rib 22 at a predetermined varying marginal spacing from the edge of the insole 20. Insole 20 is advanced in known manner (Fig. 1) by feed fingers 26 over a support roller 24 journalled in a pivoted bracket 28 which can be raised or lowered by handle 38. Conventional rib guiding means 40 and cutoff knife 42 are provided. The edge-gauge 60, by which insole 20 is accurately guided relative to the rib 22, is attached to the piston rod (65) of a pneumatic cylinder (64), Fig. 3 (not shown) to which air is supplied through valves 74 and 76. Valves 74, 76 (Fig. 5) are operated by cams 106, 108 which are mounted on a camshaft 92 driven by a reciprocating pawl 94 acting on a ratchet 96 attached to the cam shaft. Pawl 94 is operated by pneumatic ram 98 which is controlled by a solenoid air-valve 102 (Figs. 5 and 6). Valve 102 is actuated by electrical signals initiated by the passage of a pivoted contact arm 118 over a printed circuit board 124 having contacts 2L-6L and 2R-6R for left and right insoles respectively. The contact arm 118 is driven via gearing and an air clutch 150, from the insole support roller 24. Each time the contact 122 of arm 118 touches a contact e.g. 2L of the board 124 the pawl 94 advances the ratchets 96 one step so that cams 106, 108 rotate to modify the positions of valves 74, 76 which adjust the setting of the piston rod (65) and hence of the insole edge gauge 60 which alters the spacing of the rib 22 from the edge of the insole 20. When contact arm 118 reaches the end of its travel, cam 110 operates valve 112 to cut rib 22 and air clutch 150 is disengaged to allow arm 122 to return to its initial position. The contact board 124 is designed for only one size of insole and is exchanged for a different board for treatment of another size. Instead of contact board 124, a punched card, an aperture card placed over a continuously conducting surface or a system of photoelectric sensors illuminated through a punched card templet may be used.

Title: Improvements in apparatus and methods for producing latex foam
Filed: 1951-05-28
Abstract: 699,655. Foaming latex. UNITED STATES RUBBER CO. May 28, 1951 [June 8, 1950], No. 12405/51. Class 70 [Also in Group II] A foamed latex is produced continuously by injecting a gas into a frothing liquid in a closed receptacle at above atmospheric pressure, feeding the formed froth under such pressure through a discharge passage and mixing latex therewith. In operation, gas passes through a metering pump 25 into the receptacle 13 through needles 17 into the frothing liquid e.g. a soap solution which has been delivered through a metering pump 22. Froth is formed and passes through a pipe 18 into a casing 27 which contains a shearing device, consisting of a series of fixed 29, 31, and rotatable 28 bands on a rotor 32. Latex is metered through a pump 41 and passes to a distributing cup 44 situated in a pipe 43 extending downwardly from the housing 27. A gelling agent e.g. sodium or potasium silicofluoride is metered through a pump 53 and mixes with the latex. Froth leaves the housing 27 through apertures 33 in the bands and passes into and over the lip of the cup 44 where it mixes with the latex, mainly in the annulus formed between the outer periphery of the cup 44 and the inner walls of the pipe 43. Mixing is furthered by a feed screw 55 which passes the mixture through conduits into a mould 56, 57, which when filled is placed in vulcanizing apparatus. An alternative feeding mechanism for the mixture is shown in Fig. 3 consisting of discs 66 and blades 67 which squeeze and scrape the latex foam from the pipe 43.

Title: Steam engine
IPC: F01L23/00
Filed: 1946-04-26
Abstract: 616,298. Steam engines. WILLIAMS, C. C. April 26, 1946, No. 12609. [Classes 122 (ii) and 122 (iii)] A steam engine works on a superheated steam cycle, which consists in, during the compression stroke, compressing superheated exhaust steam to form a compression volume of steam of a temperature higher than the temperature of the feed steam, introducing feed steam into said compression volume of steam in the cylinder to be heated thereby and form a mixture of feed and compression volume steam of a temperature at cut-off above the temperature of the feed steam, and expanding down to point of release with the exhausting steam mixture containing superheat. The Figure shows a uniflow engine having a cylinder' 10 provided with exhaust ports 11, a valve seat plate 16, a valve guide plate 17 and a cap 18. A valve 25, the stem 26 of which carries a foot 28 engageable by the piston 14 as it nears top centre, allows feed steam, fed by pipes 20 and 21, into a chamber 19 to be admitted to a compression chamber 29. The sudden upward movement of the stem 26, due to its kinetic energy increases the pressure in a differential chamber 23. As the piston recedes the pressure in the compression chamber 29 decreases, the valve being snapped shut by the higher pressure in the chamber 23 acting on the valve stem 26, and by the steam rushing past the valve into the enlarging chamber 29, thus affording a quick cut-off. A heat retaining jacket 31 for the engine is employed so that the engine may operate at the highest temperature possible.

Title: Process for the manufacture of pulp from fibrous vegetable materials
IPC: D21C1/04
Filed: 1938-04-28
Abstract: 514,384. Wood and straw pulp. WOHL, A. April 28, 1938, Nos. 12742 and 12743. Convention dates, April 28, 1937, and May 24, 1937. [Class 2 (ii)] [Also in Group VIII] Wood is reduced to fibres by mechanical treatment after it has been heated with dilute solutions of mineral acids in such quantities and concentrations that more acid is present than is required for the neutralization of the " ash alkalinity and that the hydrolytic action does not substantially exceed that of 0.5 per cent. hydrochloric acid at 100‹C. Hydrochloric, sulphuric and nitric acids are mentioned as suitable acids. The wood to be treated is preferably de-aerated by steam or low vacuum of about 100 to 150 mm. pressure and is steeped in the acid for one or several hours at about 100‹C. On being crushed, the wood easily disintegrates into a homogeneous mass of fibres. In some cases the acid treatment is followed by alkali treatment with caustic soda or milk of lime. The process is also applicable to the treatment of straw and other fibrous vegetable materials, the acid treatment being followed by treatment with milk of lime at a temperature below 50‹C. for 24 hours. In an example, large' pieces of pine sap-wood with an ash alkalinity of 0.55 cc. N/10 acid per gramme are steeped in twice the weight of hydrochloric acid of 0.1 per cent. strength. The acid is heated to boiling and the liquid kept at approximately 100‹C. for 3 or 4 hours. After the acid has been drawn off, the wood is crushed and reduced to fibres. In another example, straw with an ash alkalinity of 2 cc. of N/10 hydrochloric acid per gramme is cut up and boiled with over four times its weight of N/20 hydrochloric acid till de-aerated and then kept at 100‹C. for 1 hour. After removal of the acid, the residue is treated with dilute milk of lime containing 6 to 8 per cent. CaO based on the weight of the straw, for 24 hours at room temperature. After draining, the residue is readily crushed into a light-coloured straw pulp.

Title: Improvements in variable speed mechanism
IPC: F16H29/22
Filed: 1923-05-16
Abstract: 219,434. Siddle, C. W. May 16, 1923. Variable-speed ratchchet gearing has its maximum speed set by arbitrary control and is variable automatically below that speed in accordance with the load. A driving-shaft 3, Fig. 1, has an eccentric sheave 4 adapted to turn upon a fixed eccentric 3', the whole constituting an eccentric of variable throw. A spring 17 tends to keep this eccentric in its position of maximum throw, but yields according to the load, so as to transmit lower speeds. The eccentric acts through a bearing 4<1> upon cams 6, Fig. 2, supported upon cranks 7<1> upon shafts 7, which are thus oscillated. Through one-way clutches 8<1>, shafts 8 are rotated in one direction. The cams 6 and a floating ring 6<1> surrounding them are arranged to make the impulses transmitted to the shafts 8 relatively long. A shaft 9 in line with the shaft 3 is driven alternatively forwards or backwards through two trains of toothed gears 11, 18 brought into action by a sliding double clutch 19. The maximum speed is determined by sliding manually a ring 16 which has a helical connection 14 with a slotted arm 14<1> engaging a projection 4<2> upon the eccentric 4. In this way the maximum throw of the eccentric is set. A one-way clutch 20 may be arranged between the shafts 3, 9 to allow the engine to be used as a brake upon a vehicle. In a modified arrangement, a crank is used in place of the eccentric.
