Abstract: 1,194,731. Knitting-m a c h i n e s . STIBBE MACHINERY Ltd. 24 May, 1968 [25 May, 1967], No. 24275/67. Heading D1C. [Also in Division G3] A double jersey jacquard machine 100, Fig. 1, of the rotary needle cylinder and dial type, has a hollow base 101 supporting a rotary knitting head 102 and a conventionally mounted superstructure 103 carrying coloured yarn packages 104. The patterned fabric 120 is drawn down and rolled! on a driven reel 102 within the hollow base. A punched tape control unit 122 is mechanically driven from the knitting machine and controls the patterning of large areas. An alternative patterning system for small areas comprises a matrix 124 in a console 125 which is connected to the machine by a cable 126. Rotary needle cylinder, Fig. 2 The rotary needle cylinder 107 is cut with tricks 107a to accommodate independent latch needles 108. Each needle has an operating butt 108a acted upon by cams 109, 110 housed in a stationary annular cam box 111 mounted upon a fixed bed ring 112. A rotary needle dial 113 is cut with tricks 113a to accommodate latch type independent dial needles 114 having operating butts 114a-d acted upon by cams 115-118 of a dial cam system carried by a stationary dial plate 119. Beneath each needle cylinder, in the same trick 107a, is provided a patterning jack 127, having a pressure butt 127a in one of a plurality of spaced planes, the butts being relatively offset, to increase the time between, in one plane, an operating butt 127d, and a tail 127e which co-operates with jack race camming 128 to cause the presser butts 127a to 'protrude from the surface of the cylinder 107. The presser butts 127a are actuated by selectors 130 mechanically linked to electro-mechanical transducers 133 operated by patterncontrolled electrical signals. Electronic patterning The electric signals representative of patterning information can be derived by the scanning, in synchronism with machine operation, of light-reflecting, or transmitting, points on a flat sheet, associated with a core store, or on a tape. Alternatively, the signals can be derived from a pattern matrix comprising multi-position switches arranged in regular order and turnable to angular positions at which the visual pattern of the switch-faces represents the desired patterning programme. The tape is employed for 2 to 4 colour jacquard work by offsetting each tape-reader. The matrix is set for 2 to 4 colour jacquard work by permutative switching circuits. With the pattern matrix a three encoder system having two scanning disc, synchronised with the rotation of the needle cylinder, is employed to provide pulses which, through gating networks, are used for needle selection and matrix scanning.

Title: A brake valve arrangement for braking wheels by compressed air, more particularly for the wheels of aeroplanes
IPC: B64C25/48
Filed: 1929-08-08
Abstract: 333,393. Rheinische Metallwaarenund Maschinenfabrik S÷mmerda Akt.-Ges., and Faudi, F. Oct. 10, 1928, [Convention date]. Fluid-pressure.-For applying compressed air brakes to the wheels on either or both sides of an aeroplane, or other vehicle, the braking pressure is controlled by a single valve which is actuated by either of two levers which actuate also two independent valves for admitting the compressed air to the brake cylinders on the two sides of the machine, the arrangement being such that when both brakes are applied the pressure in both brake cylinders is determined by the extent of the displacement of that lever which has had the greater movement, should the movements be unequal. Two brake levers 5<a>, 5b act upon two plungers in two parallel cylinders and also upon the head 23 of a plunger in a third cylinder below them. This plunger acts upon a spring 2a, Fig. 4, to displace a diaphragm 2b into contact with a plate 2<c> which is moved to open a valve 2 against a spring 24. Compressed air is then admitted from a passage 14 to a passage 17, leading to valves in the other two cylinders, and also to a space 22 behind the diaphragm 2b which is moved to close the valve 2 when the pressure built up equals the pressure applied to the springs 2a by either of the levers 5<a>, 5<b>. Movement of either of the levers 5<a>, 5b first compresses a spring to close an exhaust valve in one of the upper cylinders before it starts cocking the spring 2a, and further movement positively opens another valve in the upper cylinder to admit the compressed air from the passage 17 to the corresponding brake cylinder.

Title: Improvements in tide power generating systems
IPC: F03B13/26
Filed: 1921-09-15
Abstract: 191,780. Klug, C. Sept. 15, 1921. Tidal energy, utilizing.-A tidal power gener. ating system comprises a series of wells 1, Figs. 1 and 2, fed with water from a pipe 18, each well containing a piston 2 connected by rods 3 to double-acting pumps 6, which draw water from a tank 8 to supply a series of single-acting power cylinders 24, Figs. 1, 4 and 5, which on the instroke rotate a shaft 51 by means of cables 30, Figs. 4 and 5, connected to cross-heads 45 and wrapped around drums 31. The pistons are returned and the cables 30 re-wound by means of weights 62 attached to cables 60 wrapped around drums 59 attached to the drums 31, rotation of the shaft 51 being prevented by ratchets 55. The exhaust water is led back to the tank 8 by pipes 34. The admission and exhaust valves are operated by means of tappets on the cross-heads, the arrangement being such that each cross-head at its innermost position closes the admission and opens the exhaust valve of its own cylinder and opens the admission and closes the exhaust valve of another cylinder. For this purpose, the lever 33 of each inlet valve is connected by a link 37, Figs. 5 and 8, to the upper end of a lever 38 mounted on a shaft 39, the lower end of the lever 38 being connected to the exhaust-valve lever 36. In order to give quick action to the valves, a spring 41 fixed at its lower end is attached at 42 to the upper end of the lever 38. Each of the shafts 39 except that attached to the first cylinder has attached at its other end a strike lever 44, Fig. 4, so placed that. when the cross-head 28 nears the inner end of its stroke, a tappet 45 attached thereto strikes the lever 44 to operate the valves of the next cylinder and at the same time a tappet 46 at the opposite end of the cross-head engages the lower end of the lever 38 of its own cylinder to actuate its own valves in the reverse direction. By these means, each cylinder is operated in turn until the last cross-head actuates the lever 47 attached to the shaft 48 to actuate the valves of the lever 47 attached to the shaft 48 to actuate the valves of the first cylinder and thus repeats the cycle. The apparatus is provided with a pressure equalizer 69, Fig. 1 comprising a loaded ram in a cylinder connected with the main pipe 13.

Abstract: 1318006 Timing ignition ROBERT BOSCH GmbH 19 April 1971 [21 March 1970] 24830/71 Heading F1B [Also in Division G1] The timing of the ignition pulse of an I. C. engine is controlled by electrical signals representing physical parameters of the engine, e.g. speed, degree of vacuum in the inlet manifold, engine temperature, etc. As shown, Fig. 1, signals representing angular speed n and pressure p are fed through appropriate function generators 12, 13 to produce control signals Un, Up. These are added at 14, together with any other desired parameter signals 15, to produce a voltage signal Uv whose amplitude is proportional to the desired angular position of the distributor shaft corresponding to the ignition pulse timing. A sawtooth generator 17 is triggered by a pulse derived from the crank-shaft at a predetermined setting, to produce a sawtooth voltage Uw proportional to the crank-shaft angle and speed which is compared at 16 with the voltage Uv. When they are equal a trigger pulse is fed to the ignition system 21. At low engine speeds the system 21 is triggered at a fixed timing by pulse generator 19, the changeover being effected by a speed controlled switch 20. In another embodiment, Fig.4, the sawtooth generator 28, triggered by a pulse at the crankshaft reference position, produces a voltage whose maximum value is inversely proportional to speed. This is fed through a function generator 26 and to a pressure transducer comprising bellows 33 and potentiometer 34, the two signals being added at 14 and compared with the sawtooth voltage to trigger the ignition system 21 when they are equal. In modifications, Fig. 2 (not shown), the sawtooth generator is a rotary potentiometer.

Title: Improvements relating to closure devices or valves
IPC: C11B1/10
Filed: 1921-09-21
Abstract: 186,254. Niessen, K. Sept. 21, 1921. Fats, extracting by solvents.- The escape through a leaky valve of a liquid which does not mix with water, is prevented by providing a water seal between the liquid and the valve, so that only water escapes. In one example, a fat-extractor A is connected through a valve a and pipe b to a reservoir B containing a solvent. A tank C is constantly supplied with water and is connected by a, pipe L to the pipe b. The head of water h is greater than the head of solvent m, which is greater than the head of water n. When the extraction is finished the valve a is closed and the outlet valve e opened. The valves d, e are interconnected so that both open together. The solvent is thus forced back through the pipe b to the level g, and water only is able to escape through the valve a, if leaking. To restore the operating conditions, the valve e is closed and the valve d (which is a 3-way cock) is moved to open the upper end of the pipe L to the air. The meeting point of the solvent and water is thus raised to the level K so that the valve a may be opened and solvent only is delivered. A modification is described in which the valve d is omitted, and the valve a is replaced by a 3-way valve. If the vessel A is at a higher level, the upper parts of the vessels B and C are placed in communication with the same source of compressed air. The valves a and e may then be at an inconveniently low level, to avoid which the system shown in Fig. 3 is employed. The pipe b is extended upwards and provided with a valve X, while a pipe p connects the vessels B, C. A valve q permits the pipe p to be connected to a compressed air pipe r or an outlet pipe s. When solvents heavier than water are used, the vessel C is placed below the vessel B so that the meeting point of the liquids at g is below the valve t.

A mixture of gases having polyatomic molecules (e.g. HD and NO) or which ionize or dissociate to different extents at high temperature (e.g. He-N 2 , Ne-Hg) are separated by introduction into a chamber in which an electric arc is formed at such a temperature that one of the gases completely ionizes or dissociates, whereby separation is promoted, and removing the separated components. As shown in the Figure, argon and nitrogen may be admitted to quartz tube 11 through lines 21 and 22 and a pressure compensating vessel 20, and an arc is struck between earthed tungsten rod 19 and tungsten anodes 17 each in series with resistors 18. The D.C. may be raised to 40A whereby an arc temperature of 10,000 C. is reached in the centre of the plasma: at the wall, however, the temperature may be only 200-300 C. due to the water passing through jacket 23. Due to dissociation the number of nitrogen particles is doubled and the partial pressure changes causes the nitrogen to diffuse toward the periphery, and due to the temperature the gas of thus increased argon content rises and may be withdrawn through an outlet (not shown) in metal plate 12 whilst heavier, cooler gas of increased nitrogen content falls and may be withdrawn through an outlet (not shown) in metal plate 13. Gases containing oxygen or halogens are preferably separated with the use of carbon electrodes.

Class 64(3) In a space-heating apparatus in which an electrically driven fan 17 impels air over a battery of hot-water pipes 14 connected by pipes to a boiler 26, and through an outlet 16 into the space to be heated, the fan motor is controlled by two switches in parallel, one switch being controlled by a thermostatic device 36 in the hot-water circuit so as to close the fan motor circuit if the water becomes overheated after the other switch has stopped the fan. This other switch is operated manually or by a thermostatic element responsive to the temperature of the space to be heated. When the thermostatic device 36 re-starts the fan motor, it also closes a third switch which causes a damper 22 to open and allow the hot air air to escape into the space 50 instead of entering the space to be heated. The damper is moved by energizing a solenoid 24 or a stalling motor. Specification 758,919 is referred to.
