Filed: 1974-02-08
Abstract: 1464861 Windscreen and headlamp cleaning systems LUCAS ELECTRICAL Ltd 8 Feb 1974 [22 March 1973] 13784/73 Heading A4F Vehicle headlamp wipers and washer motors 32, 33 are energized when contacts 13, 15 of a relay switch are inter-connected by a movable contact 12 on energization of the relay coil 11 by the concurrent closure of a switch 27 for engaging the headlamp 28, 29 and a switch 31 for energizing the windscreen washer motor 30. The coil 11 is in series with a transistor 22 which is rendered conducting when the switches 27, 31 are closed by current applied to the base via a variable resistor 24 and diode 23. When switch 31 is reopened, a previously charged capacity 25 discharges to maintain the transistor conducting, providing switch 27 is still closed to keep the headlights on. Thus the headlight wiper and washer motors 32, 33 remain operative for a predetermined period. When the capacitor has discharged, the headlamp wiper motor 32 will still be maintained in operation via contacts 13, 14 and 35, 37 until, at the parking position, contact is broken between 35, 37 and established between 35, 36. Diodes 21, 23 prevent passage of reverse currents.

Title: Strip chart recorder
IPC: G01D15/28
Filed: 1953-05-18
Abstract: 740,640. Recording-apparatus. SWARTWOUT CO. May 18, 1953 [Aug. 8, 1952], No. 13892/53. Class 106 (4). A strip chart P reverses its direction of movement by passing around the edge 4 of a transversely curved plate 5 so that the chart is shaped to the curvature of the edge which corresponds to the arc of movement of a pen 11 marking the chart adjacent ot the edge. The strip of paper P is drawn from a supply roll S, round a side edge 4 of the backing plate 5, across the face of the plate 5, around a drive sprocket roll D on to a take-up spool F. The roll D has two spaced sets of teeth 6 engaging rows of perforations 7 in the paper P and the perforations 7 are larger than the teeth to allow for expansion or shrinkage due to variations of humidity. A pen arm 10 rotates about an axis A, parallel to the direction of movement of the paper P over the plate 5, and carries the pen 11 adjacent the edge 4 which is arcuately curved about the axis A so that the paper P is linearly inscribed as it doubles back on itself round the edge 4. A similarly curved face 14, preferably lined with felt 15, of an adjustable bracket 13 ensures close conformity of the paper to the shape of the edge 4 which is rounded for smoothness. The instantaneous value of the variable may be indicated by a pointer on the pen arm 10 against a curved scale 23.

Title: Improvements in or relating to the production of activated carbon
IPC: C01B32/336
Filed: 1941-10-30
Abstract: In the process of activating carbon described in the parent Specification the reaction chamber is heated by means additional to the combustion of gases produced by the activation process. For example, additional combustible gases may be admitted above the layer of carbonaceous material, e.g., through the rubber arms or through tangential openings in the side walls of all the chambers or only of the lower ones.  The gases may be obtained by reaction between a part of the glowing carbon leaving the furnace with steam, carbon dioxide &c.  Alternatively, the heat may be furnished by the combustion of finely divided solids introduced with the carbon to be activated. The heat may also be indirectly supplied to the chamber by heated hollow spaces in the ceiling or base thereof.  Specifications 446,505 and 583,113 are referred to.

Title: Improvements relating to the manufacture of fibres of glass or other similar or analogous thermoplastic materials
IPC: C03B27/02
Filed: 1949-05-31
Abstract: 673,469. Tempering glass &c. fibres. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY & CIREY. May 31, 1949 [June 1, 1948], No. 14590/49. Class 56. Glass &c. fibres having a high resistance to traction are formed by causing an intense cooling action to act on molten glass &c. streamlets 1 subjected to a mechanical attenuation after they leave the outlet orifices 2 of the melting receptacle, the cooling being effected by completely surrounding the fibres with a cooling fluid below the attenuation cone in such manner that the intense cooling takes place only below the attenuation cone. The cooling device comprises a passage 4 in which cooling water circulates with a felt front 5 interposed between the cover 6 and transverse member 7 and adjustably compressed by screws. The water delivery is controlled at 9 and the waste removed at 10. The device is adjustable vertically by means of the nuts 13 on the rod supports 12, and transversely by means of the screw 15 which causes the part 16 to pivot at 14. The felt 5 is covered at the front with a film 20 of water into which the fibres pass, (see Fig. 4). The film may be formed by two felts arranged on opposite sides of the fibre, and at the start, or in the case of the breakage of a filament one of the felts may be spaced from the fibre. The diameter of the resultant fibres is increased by 5 to 10 per cent relatively to uncooled fibres, and the resistance to traction increased for 5 micron fibres by more than 50 per cent, and for 20 to 50 micron fibres by 250 to 300 per cent. The fibres may be cooled by oil in the form of an emulsion or not, by metal bodies, e.g. mercury, cooled by water circulation or refrigerant, by gaseous fluids such as CO, from carbonic snow over which the fibres pass, or by gases of high conductibility e.g. H 2 , and in all cases the whole periphery of the fibre is cooled. The cooling liquid may flow over a base of polished metal or porous bodies such as soft porcelain, felt, porous wood, and in some cases a solid surface of revolution may be used which rotates and is covered with a layer of liquid as it passes into a tray containing the liquid. Wavy fibres may be produced by superposing, simultaneously with.the cooling action, a mechanical action, e.g. causing the fibres to pass on to a suitably shaped member such as a tube or a wire on which streams a cooling liquid. Specification 673,468 is referred to.

Title: Improvements relating to frozen foods and methods of making the same
IPC: A23G9/32
Filed: 1944-07-31
Abstract: Ice cream &c. is made from a mix containing solids, sugar and flavourings and having a pre-determined weight per gallon and fortified with milk, minerals and cultured lactic acid starter. The mix may also contain soya powder, defatted.  The ingredients are standardized as to weight and acidity so as to give a standard weight per gallon excluding overrun.  The milk ingredients may be cream, milk or powdered or condensed milk containing about 0.50 per cent. of milk minerals.  Adding further milk minerals increase the total percentage of such to 1 per cent. and reduce the acidity to pH of 7, or slightly below.  If the milk solids in the mix are below the prescribed proportion (in U.S.A.) added milk solids, not fat, obtained from milk powder or the solids of defatted and dehydrated soya bean powder may be used to make up.  To this mix, cane or beet sugar with preferably a percentage of corn sugar, is added and tested for acidity.  The cultured starter is then added, the starter (lactic acid bacteria) of the desired character being preferably grown in the same medium as the mix, sufficient starter being added to obtain an acidity of .10 to .20 per cent. nafis scale. 150 lbs. of such starter should be added to 1,000 lbs. of mix.  The mix medium for growing the culture is heated to 190 DEG F or above for one hour, then cooled at from 68 DEG F to 70 DEG F, after which the mother culture is added. After curdling the cultured starter is cooled to 40 DEG F or lower. When added to the main mix the whole is circulated or agitated and pasteurised about 150 DEG F.  The mix is then homogenized and cooled to 40 DEG F after which it can be frozen to make the ice cream.  When fruit juices, chocolate, nuts, syrups or fruit are to be added which would unbalance the acidity, these additions are standardized as to acidity by adding sufficient milk minerals to them.  Specification 589,031 is referred to.

Title: Improvements in or relating to the regulation of refrigerating machines
IPC: F25D11/02
Filed: 1937-05-27
Abstract: 480,567. Refrigerating. SVENSKA AKTIEBOLAGET GASACCUMULATOR. May 27, 1937, No. 14714. Convention date, June 13, 1936. [Class 29] [Also in Group XXIX] Absorption machines.-The production of cold by a heat-driven refrigerating machine comprising a circulation system containing at least one circulating medium, is regulated by supplying a regulatable amount of heat from the heat source driving the apparatus, or from a heat transmitting system between the heat source and the boiler of the apparatus, or from the circulating medium in the part of the system receiving heat from the heat source, to a, place outside the same. The temperature differences in the system are thus reduced and the refrigeration is decreased. In one construction the boiler 7 of a refrigerating system is heated by a cooking range 2 through a Perkins tube system 4. The apparatus further comprises a condenser 10, evaporator 12, and absorber 15. Heat is withdrawn from the system 4 by a boiler 17 connected by tubes to a condenser 20 which warms the condenser 10 of the refrigerating machine. A valve 22 controls the circulation and thus regulates the quantity of heat transferred. In other constructions the boiler 17 may be situated around the boiler of the refrigerating machine or a rectifier, or be asso-. ciated with the heat pump of the machine. The condenser 20 may be alternatively in the outer air or in association with the evaporator or evaporator absorber connection. The valve 22 may be thermostatically operated. A tube 30 from a thermostatic capsule in the refrigeration chamber is led to a bellows 27. The latter is held by a spring 32 against an adjusting screw 29. The bellows operates the needle valve 22 through a spring 33. Specification 371,192, is referred to.

Filed: 1968-03-27
Abstract: 1,208,952. Packages-packaging machines. TABAK - UND INDUSTRIEMASHINEN DRESDEN, VEB. 27 March, 1968, No. 14801/68. Heading B8C. A machine for packaging large, irregularly shaped articles in gussetted bags comprises two gusset shaping members 14, a vertically arranged tube forming device 4 having a longitudinally displaceable filling shaft 5, welding or sealing devices 12, 13 for producing longitudinal and transverse seams respectively of a tubular bag formed from a foil web 35, and a vertically adjustable stop 23. The two gusset shaping members 14 are securely mounted directly above or below the transverse welding or sealing jaws 13 and are formed as spaced helical springs. The vertically adjustable stop 23 is arranged one bag length below the jaws 13.  In operation the material to be packaged is inserted in the filling opening 6 of the filling shaft 5, the jaws 13 being in a closed position. The machine is switched on, and the jaws 13 open, actuating a downward movement of the loaded filling shaft 5. During this movement a web of packaging material 35 is reeled off a bobbin and formed into a tube by the device 4. The resilient gusset shaping members 14 are downwardly deflected as the loaded filling shaft 5 moves down past them (Fig. 6, not shown). The leading edge of the downwardly moving shaft 5 strikes the stop 23, and operates a limit switch 37 (Fig. 2, not shown) thereon which trips the upwards return movement of the filling shaft 5 to its original upper position, the welding stirrup 12 being swung away from the tube. The transverse welding or sealing jaws 13 are closed and an upwards displacement of the stop 23 is initiated simultaneously. The gusset shaping members 14 resiliently engage the packaging material tube, to fold the tube material to form a gusset. This is facilitated by the upward displacement of the stop 23 which relieves the stresses in the tube material during the transverse sealing of the bag. As the jaws 13 open for the next working stroke, the stop 23 is tilted (Fig. 1) whereupon the bag thereon slides off on to a conveyer belt. The gusset-shaping members 14 may be mutually adjustable in their axial direction at right-angles to the longitudinal axis of the tube. The length of the bag may be adjusted by displacing the stop 23 by means of a clamping device.
