Title: Improvements in the manufacture of faced tiles or the like
IPC: B28B1/16
Filed: 1933-06-09
Abstract: In a process for manufacturing tiles, dry or liquid cement is introduced into a mould to form a facing layer, and a backing of dry cement with or without sand, fibres, or other reinforcement or aggregate, following which the whole is placed and maintained under pressure while it absorbs water and sets.  The mould may have a plain, figured, or embossed glass bottom, and a perforated or embossed top plate to form keying projections in the back of the finished tile.  To produce figured tiles, the glass surface of the mould may be covered with a solution of water glass on which the desired design is painted or stencilled in coloured cement. The facing and backing layers then are added as before.  When figured glass is used, the recesses may be painted with one colour and the background with another.  In one method of manufacture a number of shallow moulds having gaps at the corners are charged and then superposed in a press.  While under pressure, the stack is turned so that one edge of each mould is immersed in water which is absorbed by the dry material through the corner gaps of the moulds.  Calcium chloride may be added to the water to speed up the process.  The faces of the completed tiles may be waterproofed by treatment with soap solution.

Title: An improved means for carrying and closing cardboard boxes
IPC: B65D5/462
Filed: 1932-06-13
Abstract: 403,086. Cardboard boxes. FILMER, R. H., 9, Allen Street, Clerkenwell, London. June 13, 1932, Nos. 16648 and 31754. [Class 18.] Improved means for carrying and closing cardboard boxes comprise a lid formed of two layers d hinged at d <1> to the tops of two opposite sides a of the box, each layer d having approximately the same area as the top of the box, and one layer being adapted to fold down on to the other which rests on supporting means such as flaps c, and a handle portion h formed by slitting each layer between a crease e and the free edge d<2> of the layer, the creases acting as hinges for the handle portions and one handle portion being adapted to pass through the gap from which the other handle portion was cut, while a clip holds the two layers of the lid together. This clip may comprise a portion d<3>, formed when cutting one handle portion, and a slit m for it to engage in. The hand holes g in the handle portions are formed by slits g<1> and a portion j may be left hinged to the crease e in one layer to close any gap which might appear between the handle portions. The crease e may only extend the length of the handle portion, and one handle portion may be wider than the other, the narrower one being extended by slots l. This ensures the two handle portion being in contact. The sides a of the box may be inclined and formed with ventilation holes k. The handles may be bent down either both to one side or one to each side of the creases e when the boxes are to be stacked. The hand holes g may be cut so that portions are left between them and the creases e, or the nut g<1> may extend along the creases e and around the ends of the gap g thus forming a flap which may be turned against the face of the handle hand sewn thereto. In another form, the gap g is formed by cutting two hinged flaps, one of which may be sewn against the handle portion h while the other which is hinged to the crease e sewn to close any space at the centre of the box when the lid is closed. In place of the supporting flaps c external pockets may be formed at the ends of the box by flaps hinged to the two long sides thereof and extension flaps on the under layer of the lid are formed to fit into said pockets. A modified form of box suitable for carrying a single bottle has the crease e in the under layer of the lid coincident with the hinge connecting the layer to the side of the box while the crease in the upper layer is positioned to coincide with the top of this side of the box. The extension of the upper layer beyond the crease e folds down against the long side of the box, the projection d<3> engaging a slot therein, and the handle portions then project from one edge of the box. This box has double ends, each outer face being formed by two flaps hinged to the sides of the box, and each inner face by a flap hinged to the bottom of the box. These last mentioned fiaps support the under layer of the lid.

Title: Improvements in and relating to the finishing treatment of fabric and garments of thermo-plastic yarn
IPC: D06C5/00
Filed: 1945-07-02
Abstract: <PICT:0631448/IV (c)/1> Textile articles made of thermoplastic yarn, particularly nylon or other polyamide synthetic product, are plasticized by being placed on a shape, form or template designed to hold it to the desired shape, heating the form internally by electric resistance heating, and submitting the article, while on the form, to an ambient atmosphere, which may contain steam, having a temperature of at least 212 DEG  F.  As applied to the pre-boarding of nylon stockings, these are placed on electrically-heated forms 1, which are traversed by an endless conveyer 2 through a treatment chamber 3, which may be subdivided by partitions 4 to form two corridors 3a, 3b, in which the laps of the conveyer run.  Current is supplied to the forms by contacts 6 and 7 thereon engaging contact rails 9 and 10 extruding lengthwise of the corridors.  Steam at from 212 DEG  to 270 DEG  F. may be supplied to the chamber by blowing air through a steam radiator, injecting steam into the air-stream, and passing the mixture through a bare-wire electric heater; or by having bat-wing gas burners supplied from a pipe 17 in the chamber 3, and injecting steam under pressure from jets in a pipe 18, above the burners.  The forms 1 include an electric heating element consisting of wire or ribbon wound on a former of mica or other non-conducting material, this being sandwiched between two further sheets of mica or the like and enclosed between two dished metal cover-members which are welded together around their edges. External sliding contacts protrude from the insulating block at the base of the form.  According to the Provisional Specification, the forms may be heated externally by infra-red radiation, in which case they are advantageously a dull black.

Title: Improvements in or relating to electric pulse modulators employing crystal triodes
Inventor: PRICE JOHN CLIFFORD
IPC: H04J3/08
Filed: 1954-06-08
Abstract: 747,541. Pulse modulation and shaping circuits. STANDARD TELEPHONES & CABLES, Ltd. June 8, 1954, No. 16769/54. Classes 40 (5) and 40 (6). A relaxation circuit of the type described in Specification 726,496 employing a transistor 1 with feed-back from the collector 4 over series circuit 5, 6 to the emitter 3 is held normally blocked by a battery 11 which maintains the emitter negative with respect to earth over conducting diode 12. The emitter and collector are connected over resistors 8, 10 to large positive and negative batteries 7, 9. Since only a very small collector current flows, its potential is near that of battery 9 and rectifier 15 is held non-conducting. A train of regularly recurring positive pulses is applied over transformer 13 each causing the circuit to generate a positive-going pulse at the collector which is limited near the potential of battery 32 due to diode 15 conducting. It is stated that the trailing edge of the collector pulse is determined by the potential on the collector and this is varied by speech applied over transformer 18, a capacitor 17 maintaining the potential constant during the generation of the pulse. Slicing circuit. The pulse at the collector is fed to a slicing arrangement comprising a normally conducting diode 29 and blocked diodes 21, 30 so that the output terminal 27 is at the potential of battery 25. When the pulse occurs, the collector potential rises, the junction of the diodes rising until diode 30 conducts thus carrying the output terminal to this level, Fig. 2 (not shown), since diode 21 conducts as soon as the junction rises above battery 11. The duration-modulated pulses may be converted to phase-modulated pulses by differentiating transformer 23, diode 26 suppressing the leading edge of the pulse. It is stated that the delay in the occurrence of the trailing edge is due to the time taken to collect stored minority carriers. In order to increase the percentage modulation, the pulses are reduced, an opencircuited delay line being used, Fig. 4 (not shown).

Title: Improvements relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1950-07-05
Abstract: 676,668. Refrigerating. EGLI, A. R. July 5, 1950 [March 2, 1950], No. 16825/50. Class 29 In absorption refrigerating apparatus of the continuous-cycle inert gas type the flow of inert gas through the evaporator 5 is regulated automatically in proportion to the flow of liquid refrigerant by a liquid refrigerant seal 11a which causes a progressive change in the open area of an elongated inclined opening 10 of a casing 7 interposed between the inner pipe 8 and the outer pipe 6 of the gas heat exchanger, allowing part of the poor gas from the absorber to return to the absorber, without passing through the evaporator, when the flow of liquid refrigerant decreases. The pipe 11 conveying rich gas from the outer pipe 6 of the gas heat exchanger to the absorber is extended upwards to form a dam for liquid refrigerant, and the inner pipe 8 has an aperture 9 communicating with the casing 7 having an open slot 10 situated below the level of the dam. The gas heat exchanger is arranged at a slight angle to the horizontal so that a progressive closing or opening of the slot 10 takes place as the level of the liquid seal rises or falls. When the level falls, a portion of the poor gas leaves through the apertures 9, 10 and flows directly back to the absorber through the pipe 11. The reduced flow of poor-gas through the evaporator results in some of the refrigerant flowing unevaporated into the heat exchanger which raises the level of the liquid seal 11a until the opening 10 is again closed.

Title: Cheese manufacture and the like
Inventor: REITER BRUNO
IPC: A23C19/032
Filed: 1955-06-13
Abstract: In the manufacture of cheese, butter or margarine, milk to be used for preparing a bulk starter is contacted with an ion-exchange material for substantially complete removal of the calcium content i.e. to less than 20 parts per million; the calcium-reduced milk is of value since it is bacteriophage-resistant.  According to a comparative example, 10 gallons of calcium-reduced milk of calcium content 9 parts per million and a similar quantity of untreated milk were inoculated with 1 per cent. of a starter culture and both were immediately infected with sufficient bacteriophage to ensure lysis of the starter culture and cessation of acid development in the milk. After 16 hours at 75 DEG F. the milk starter had developed only to an acidity of 0,3 per cent. whereas Cheshire cheese was produced with the calcium-reduced milk, the time from rennetting to milling being 3 hours 50 minutes.ALSO:Milk is contacted with an ion-exchange material for substantially complete removal of the calcium content, i.e. to less than 20 parts per million.  Milk may be contacted with a weakly-acidic cation-exchange resin of the carboxylic-acid type in which the major part has been converted from the acid form into the alkali form, so that the milk after contact has a pH of about 7.  The calcium-reduced milk is of value since it is bacteriophage-resistant and may be used for preparing the bulk starter in the preparation of fermented milk products.  Bacterial nutrients and a calcium sequestering agent may be added to the ion-exchange treated milk which may then be reduced to a powder for reconstituting with water when required.  A composition consists of 92 per cent calcium-reduced milk solids containing 3 per cent butter fat and minor proportions of enzyme digest of casein, corn steep liquor, sodium acetate and a sequestering agent such as ethylene diamine tetraacetic acid disodium salt.

Abstract: 944,304. Classifying granular materials. AMALGAMATED ROADSTONE CORPORATION Ltd. Nov. 6, 1962 [Aug. 9, 1961], No. 16888/61. Heading B2H. A method of separating hard ragstone from softer, less dense materials quarried with it employs a crusher of the impact type which has a rotary drum carrying projecting blowbars, passes the material thence to a wet-feed mechanical screen 5 which separates the larger, hard particles from the smaller, soft particles and then passes the separated larger particles through a float-and-sink dense medium separator to remove the remaining soft, less dense, particles from the hard, dense particles. A vibrating srceen 1 removes material of less than 3 inch size from the quarried stone which is passed to the crusher 27 thence to the hopper 3, with its mechanical feed 4. On the screen 5 the soft material picks up water more readily from the sprays 6 than the ragstone, whilst sand passing through the screen is collected in a sand preparation machine 8. The float-and-sink separator has a drum 13 divided into compartments 14 and 15 respectively containing suspensions of magnetite and ferrosilicon in water of specific gravity 2À0 and 2À5 which float off the lightest material to one compartment 16 of a wash-and-drain screen 17 whilst heavier material passes by way of water-washed hoppers 18 and 20 to other compartments 19 and 21. The separated materials are drained in sumps 23, 24 and 25 whence the liquid is recirculated, that from sump 25 being passed through a magnetic separator 29, a densifier 31 and a demagnetizing coil 32 before recirculation.

Title: Improvements in means for transmitting measured torque
IPC: F16D7/10
Filed: 1942-11-30
Abstract: 564,417. Dynamometers. HIXSON, J. E. H., and WOODMANSEE, J. L. Nov. 30, 1942, No. 17031. [Class 106 (ii)] [Also in Group XXII] Means for transmitting measured torque comprise epicyclic gearing having an element linearly oscillated by a driving member and coupled to a driven member, the reaction of the element with a casing exerting thrust on a piston to produce a fluid pressure affording a measure of the torque being transmitted. The invention is shown applied to a device for driving screws. The drive is applied by a hand lever 2 secured to a spindle 1 having an eccentric portion 3 on which is freely mounted the linearly oscillated element or gear-wheel 4 engaging pins 11 on a driven member 10 concentrically arranged with respect to the spindle 1. The gear 4 is held from rotation, but is allowed to slide, relatively to a normally fixed face-plate 6 by an Oldhams type coupling 5. The face-plate 6 is normally connected to a casing 8 having teeth 8b engaging a rack connected to a piston 23 in a closed fluid-pressure circuit. Rotation of the spindle 1 through the gear-wheel 4 and pins 1 causes rotation at a reduced rate of the driven member 10 and tends to rotate the casing member 8 with a force proportional to the torque being transmitted. This force is measured by the rise in pressure in the fluid pressure system. Ball valves in this system are arranged so that the pressure can be measured for either direction of rotation of the spindle 1. The face-plate is connected to the casing member 8 by plungers 17 held in position by bars 19. This connection can be broken and the hand lever 2 connected directly to the driven member 10 by withdrawing the plungers 17 from engagement with the casing member and moving the bars 19 into a position 19<1> in which they engage recesses 7 in the hand lever 2.. The torque is applied to the screw to be driven by means of a key 20 splined to the driven member 10 and movable axially by means of a rod 21. The lever 2 may be motoroperated and the fluid pressure may be balanced against a reference pressure for operating means to cut off the motor power supply when a predetermined torque is reached.
