Title: Improvements in or relating to apparatus for expressing liquid constituents from materials of various kinds
IPC: B30B9/20
Filed: 1926-05-06
Abstract: 252,005. Krupp Grusonwerk Akt.- Ges., F. May 7, 1925, [Convention date]. Addition to 248,372. Oil-presses.-The apparatus, for the treatment of oil-containing and other material described in the parent Specification, comprising an annular chamber between walls 2, 3 into which the material is pressed by a rotary feeder 8, is modified by making the walls 2, 3 rotatively tiltable relatively to each other, so that they are further apart at the position where the feeding device 8 is acting. The tilting may be effected under the pressure of the material forced in or positive means therefor may be provided. One or both of the walls 2, 3 mav be formed as a strainer. As shown in Fig. 2, the hub 9 of the inner wall 3 is mounted on an eccentric 17 fixed to the spindle 7 under the hub 16 of the feeding finger 8. As shown in Fig. 3, the wall 3 is tilted with the spindle which passes through an eccentric 19 in a neck bearing 18. Excessive pressure in the straining chamber may cause the finger 8 to rise against the force of a spring, the motion being communicated by levers to discharging knives 12. The outer wall 2 may be tilted by a roller engaging with the inside of its upper edge and carried on an arm from the spindle.

Title: Method of making coloured plates from mixtures of hydraulic binding agents and fibrous substances
IPC: C04B28/02
Filed: 1936-04-27
Abstract: Coloured roof, floor, or wall plates, or moulded articles such as cups, trays or knobs are made by mixing hydraulic cement, asbestos, and colouring matter, adding about 5 per cent of water, preferably as a fine spray, treating in a centrifugal mill to separate the asbestos fibres and mix the composition, moulding the mixture, and setting by placing the moulded article between moistened plates, cloths, or the like.  Aluminous cement may be employed, and resistance to wear increased by the addition of quartz or corundum to the composition before moulding.  For wall plates, the cement may be partly replaced by slaked lime, in which case, setting is brought about by treatment with moist carbon dioxide.  According to an example, 80 parts of cement are mixed with 12 parts of asbestos and 4 of colour.  4 Parts of water are added as a mist, and the mixture is passed through a centrifugal mill.  25 parts of quartz granules are added to the woolly mass, and the whole is pressed in moulds, and set between moist plates.

Title: Improvements relating to thermo-plastic polymeric materials
IPC: C08F2/44
Filed: 1943-07-26
Abstract: Granular or friable thermoplastic water-insoluble polymeric materials, suitable for moulding purposes, are manufactured by evaporating a solution obtained by polymerizing a substance having a CH2 = C< group in a homogeneous mixture of water and a more volatile liquid which is a solvent for the polymer. Preferably, the homogeneous mixture contains a plasticizer in solution, and optionally the polymerization is carried out at super-atmospheric pressure with or without an organic peroxide catalyst.  Specified polymerizable substances include esters of acrylic and methacrylic acids and vinyl esters, particularly methyl methacrylate, ethyl acrylate and vinyl acetate; preferably, the monomer has the formula CH2 = CR1COOR2 (R1 = H or aliphatic hydrocarbon residue and R2 = aliphatic hydrocarbon residue).  Preferably, the volatile liquid is an hydroxy-free compound containing C, H and O; specified are esters, e.g. methyl acetate, ethers, e.g. methylal and methylene ethylene ether, and ketones, e.g. acetone and methyl ethyl ketone. Specified plasticizers are dimethyl, diethyl, dibutyl and di-(methoxymethyl) phthalates, methyl-phthallyl ethyl glycollate, tricresyl phosphate and tri-(mono-chlorethyl) phosphate. Specified catalysts are benzoyl peroxide and peracetic acid. Polymerization may be carried out by means of ultra-violet light. Preferably, the monomer is dissolved in less than its own weight of the liquid medium, and in an example the proportions are methyl methacrylate 125, dimethyl phthalate 10, acetone 64, water 23.5 and benzoyl peroxide 3.3.  In a preferred process the proportions are such that all the polymer remains in solution at the polymerization temperature, but precipitation occurs if the final mixture is cooled to room temperature.

Title: Improvements in cross-bar switch arrangements
IPC: H01H67/26
Filed: 1945-05-15
Abstract: 615,975. Automatic exchange systems. NEWTON, E. P. (Telefonaktiebolaget L. M. Ericsson). May 15, 1945, No. 12220. [Class 40 (iv)] In a cross-bar switch operated by a series of impulses, contact sets on an operating bar of a switch magnet which is energized and de-energized for each pulse are successively marked by the selecting magnets and operated by an operating magnet, each selecting magnet preparing contacts for the succeeding selecting magnet, and means being provided for holding the latter magnet when the operating magnet is released. In the construction shown in Fig. 1, upon a call in line L relay IMR is operated, followed by a slow-release relay TBR. On the first break of current, relay IMR energizes selecting magnet STMo and relay HR1. The latter completes a circuit over winding I of operating magnet HBRM. Magnet STMo completes a circuit for relay IVR which is, however, at the moment shortcircuited by relay IMR and also prepares a circuit for selecting magnet STM1. Magnet HBRM now operates and completes a circuit for relay STR which locks and breaks the circuit for magnet STMo which, however, receives holding current over its contact 3. On the next operation of relay IMR, relay IVR operates and, on the second break, magnet STM1 and relay HR2 are energized. At the moment the bar of magnet STM1 is held by the operation of magnet HBRM, but relay HR2 releases the latter to free the bar magnet STM1, thus interrupting the circuits of magnet STMo and relay HR1. Magnet HBRM now energizes over winding II, which is wound oppositely to winding I to ensure complete release for a brief period. The reoperation of IMR releases IVR and the cycle continues as long as impulses are received. By the use of extra contacts in the cross-bar construction, relays HR1 and HR2 can be dispensed with. Fig. 3 shows such a system used in apparatus where Li is the incoming line and the outgoing lines are connected to the individual contacts of operating magnets, as shown, for example, at Lo. A test relay LYR is included in addition to those corresponding to the construction shown in Fig. 1. A call on line Li operates relay IMR and causes successive operation of magnets STMo, STM1, &c. as previously described and at the end of the pulses an appropriate magnet remains operated. Relay SMR which holds during impulsing, releases and breaks the circuits for the selecting magnets and connects up the circuits of magnets BRMO, BRM1, BRM2, &c. so that they operate in rapid succession and through contact 7 of SMR relay LYR tests the outgoing lines. Relay LYR has a quicker make time than magnets BRMo &c. so that when a free outgoing line is found the relay operates and stops the successive operation and connects Li to the selected line. On clearing of the communication, relays LYR and STR are released and thus also the particular operating magnet BRM that has acted.

Title: Improvements relating to fluid pressure indicating devices
IPC: B60T17/22
Filed: 1956-04-24
Abstract: 834,805. Fluid actuation of switches. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and HOGBEN, R. J. April 17, 1957 [April 24, 1956], No. 12460/56. Class 38 (5). [Also in Group XXXIV] A warning device is adapted for connection to at least two individual fluid pressure systems and is responsive to a drop in pressure below a predetermined value in either or any of the systems to actuate, regardless of the pressure prevailing in the other system or systems, a common arm 21 to a warning position. Fluid under pressure in chamber 11 acts upon the piston 13 to cause the compression of spring 19 and the movement of piston-rod 14 to the right, allowing the rotation of crank-shaft 22 and pin 27a under the action of a spiral spring (not shown) to rotate arm 21 anticlockwise. If the pressure in chamber 11 falls below the desired level, piston 13 and rod 14 move to the left under the action of spring 19, and arm 21 is raised to the warning position shown. A second identical piston and rod is arranged parallel to or in axial alignment with the one shown in order to give a warning for a completely independent system. The arm 21 may actuate electrical contacts of an electrical warning device.

Title: Improvements in Spring Starters for Internal Combustion Engines.
Inventor: LINDGREN PHILIP CHARLES
IPC: F02N5/02
Filed: 1917-08-30
Abstract: 117,527. Lindgren, P. C. Aug. 30, 1917. Turning-gear.-In turning-gear in which a power spring 8 is wound up from an engine-connected shaft 2 acting through a speed-reducing train, all the members of the train preferably intermesh within a closely limited trans-axial zone, and the final driven member 11 of the train is irternally toothed and supported externally by bearings on the casing. In the form shown, the starter casing 1 is rigidly mounted by means of flanges 1<a> on the end bar of the chassis frame, and the power spring 8 is secured to the casing 1 and to the hub 11<a> of the gear 11, which runs in ball bearings 20, 22. The speed-reducing train comprises an internally-toothed master wheel 12, controlled by a brake strap 16 and having one more tooth than the gear 11, a floating planet pinion 14, and a driving-pinion 13, the inner members running in ball bearings on the outer members and on the casing. The brake strap 16 is tensioned by a spring acting on an arm 17<b> connected to one end of the strap, the other end being secured to the casing. The pinion 13 has ratchet-teeth 13<b> for engagement with corresponding teeth on the starter shaft 4, which runs in ball bearings 30, 31 and is connected by a loose squared socket joint with an engine-connected shaft 2. When the spring 8 is sufficiently wound, the clutch 13b is automatically disengaged by the longitudinal displacement of a threaded, nut 40 in the hub 11<a>. The nut 40 bears against a spring 46, a sleeve 47, and ball bearings 31 in contact with a flange 4<c> on the shaft 4. A spring-pressed ball 48 holds the sleeve 47 until the spring 46 is compressed, when the spring moves the sleeve 47 and the shaft 4 sharply to the left in Fig. 2, disconnecting the clutch 13<b>. For starting, the strap 16 is freed from the gear 12 by means of a control connected to the lever 17<c>. The spring then drives the gear 11, the hub of which is provided with ratchet teeth engaged by spring-controlled pawls 61, Fig. 4, pivoted on a sleeve 60 splined on the starting- shaft 4, which is thus driven by the spring 8. When the shaft 4 overruns the hub 11<a>, the pawls 61, which have weighted tails 62, are withdrawn from contact with the ratchet teeth by centrifugal action. Meanwhile the nut 40 re-engages the clutch 13b, and on releasing the lever 17<c>, the strap 16 holds the gear 12 and causes the engine, acting through the clutch 13<b>, to rewind the spring. In the event of premature ignition, the gear train rotates bodily in the direction for winding the spring, which stops the rotation.
