Title: Automatic telephone call-box
IPC: H04M17/02
Filed: 1929-10-31
Abstract: 344,378. Coin-freed telephone apparatus. JENKINS, A. ROGERS-, 21, Chiswell Street, London.-(Villiers, P. G. T. de; 65, Vos Street, Pretoria, South Africa.) Oct. 31, 1929, No. 33060. [Class 27.] Coin action, weight.-In a coin-freed telephone system, mechanism operated in conjunction with a dial transmitter determines, in accordance with the number of digits dialled, whether the call is to be set up wholly automatically or through an operator. In the first case, the coin removes a short circuit across the microphone, and in the second case, the operator checks the insertion of coins by a buzzing signal as described in Specification 162,639, [Class 27, Coin-freed apparatus &c.]. A shaft 1 coupled to the shaft of the dial transmitter drives a ratchet wheel 5 by means of a spring-controlled pawl 4, the wheel being held by a spring catch put into action by removal of the receiver. If the number of digits dialled signifies a full automatic call, a cam 7 on the shaft of the ratchet wheel closes contacts 10, 12, and a further cam 17 permits a hinged magnet 18 to drop. When the coin is inserted in chute 13, lever 14 is tripped and held by magnet 18 so that the shortcircuit across the microphone terminals 27 is removed. If a smaller number of digits is dialled, contacts 10, 12 are not closed and magnet 18 is not dropped so that a buzzing signal is sent over circuit 16, 15, 9, 11 when a coin is inserted. Specification 163,280, [Class 27, Coin-freed apparatus &c.], also is referred to.

Title: Improvements in or relating to electric oscillation generators
IPC: H03B21/04
Filed: 1936-12-02
Abstract: 486,448. Frequency measurements. STANDARD TELEPHONES & CABLES, Ltd.. and JACOBSEN, B. B. Dec. 2, 1936. No. 33100. [Class 37] [Also in Group XL] In an oscillation-generator suitable for use in wave-analysis, an output frequency variable from, for instance, 0 to 100 kc./sec. is produced from a standard input frequency of 1000 c. /sec. by intermodulating the outputs of three oscillators, which are calibrated respectively from 1 to 1000 c./sec., from 0 to 9 kc. /sec. in ten steps, and from 0 to 90 kc. /sec. in ten steps, to give a direct reading of the output frequency. For the analysis of complex waves a variable band-pass filter is constructed by feeding into a fixed band-pass filter with a narrow pass band the output from a modulator into which the complex wave is fed together with the variable oscillation produced by means of the above oscillation-generator, the construction of which forms the subject-matter of the invention. The oscillator may be calibrated in terms of the difference between the frequency which it generates and the frequency of the fixed filter. A second oscillation generator constructed according to the invention is used for producing a comparison frequency, and may have some parts in common with the first oscillator. Specification 475,531, [Group XL], is referred to.

Title: Loudspeakers
IPC: H04R7/02
Filed: 1973-07-11
Abstract: 1427778 Loud-speakers ELECTRO ACOUSTIC INDUSTRIES Ltd 10 July 1974 [11 July 1973] 33121/73 Heading H4J The former carrying the voice coil of a moving coil loud-speaker is secured to a substantially central aperture in the diaphragm 2 by a cured rigid unsaturated polyester resin 4 as adhesive. The resin 4 can be one used for casting, for example it may be prepared from a mixture of phthalic or isophthalic acid, maleic or fumaric acid, and a glycol such as propylene glycol. Preferred hardeners are those which do not begin to cause hardening until specifically activated, so that the resin/hardener mixture has a long pot life and is easy to handle. The hardener may be di-isopropoxyperoxydicarbonate, which is activated by infra-red radiation or "TRIGONOX" (Registered Trade Mark), which is activated by ultraviolet radiation. Thickeners or thinners may be added to adjust the viscosity of the mixture. Suitable thickeners are china clay or polyacrylates. Pigments may be added to render the adhesive readily visible on the materials to which it is being applied. Red pigment, used when the hardener is activated by infra-red light, absorbs the radiation and accelerates the hardening. In one example the proportions of resin to hardener to pigment to china clay by weight are 100 : 2 : 2 : 50. The amount of china clay added is such that the viscosity of the adhesive permits application of the adhesive by extrusion from a nozzle. The voice coil former is adhered to aperture 3 at the apex of diaphragm 2. This is of moulded paper. A corrugated suspension 5 is of moulded and impregnated material. Diaphragm 2 may be conical, elliptical or have a polygonal base.

Abstract: 1,024,972. Dispensing containers. UNILEVER Ltd. Aug. 17, 1962 [Sept. 15, 1961], No. 33266/61. Heading B8D. A resiliently deformable container for shampoo and the like having a body 1 and a head portion 3 defining a passage 5 through which substance is dispensed has an apertured diaphragm 6 across the passage positioned inwards from its outer end to prevent air being sucked into the body portion when the container starts to resile after dispensing some of its contents. The diaphragm may be curved inwards and has a plurality of openings 7 which may be positioned around the periphery of the diaphragm to ensure that the contents are extruded in a single stream. To further this purpose an insert 10 is provided in the passage having an annular recess 12 on to which contents squeezed from the container impinge and are deflected towards the axis of the passage. In one example a substance of viscosity 40,000 centipoises was used and the diaphragm had openings of less than 2 millimetres and in another the viscosity was 4000 centipoises and the openings less than 1 millimetre diameter. The passage may be of reduced diameter at its outer end, and may be so reduced that the contents can be delivered drop-by-drop.

Title: Improvements in or relating to the manufacture of lake pigments
IPC: C09B63/00
Filed: 1938-11-17
Abstract: 521,509. Lakes. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 17, 1938, No. 33472. Convention date, Nov. 17, 1937. [Class 2 (iii] In the' manufacture of insoluble rosinated calcium salts of acidic azo dyestuffs, especially Lithol Red, the lake producing reaction is carried out in the presence of a sulphuric acid ester (preferably in the form of an alkali metal salt) of an aliphatic alcoholic compound containing at least 8 carbon atoms in its alcoholic radicle, or a mixture of such compounds, the said ester or mixture of esters being preferably added, e.g., in an amount from 1-5 per cent. of the weight of the pigment, to the undeveloped azo dye subsequent to the completion of coupling but prior to the formation of the rosinated calcium salt. In an example, 2-naphthylamine-1-sulphonic acid is diazotized and coupled with #-naphthol, and the resulting dyestuff, in the form of its sodium salt, is boiled in aqueous solution with I Wood rosin which has been saponified with caustic soda, with the addition of lauryl sodium sulphate. B Wood rosin saponified with caustic soda is then added and the mixture is boiled with calcium chloride solution, producing a bluish red or maroon pigment. Alternatively, the lauryl sodium sulphate may be added to either dyestuff component prior to coupling, or to the suspension of the precipitated pigment prior to or during its development at elevated temperature. The rosins may be replaced by other grades, e.g., M gum rosin.

Title: Improvements in or relating to dish-washing machines
IPC: A47L15/42
Filed: 1947-12-18
Abstract: 641,017. Dish-washing machines. JONES, D. G., and WHITE TILE HEATERS, Ltd. Dec. 18, 1947, No. 33495. [Class 138(i)] In a dish-washing machine of the type having in combination a rack for the dishes, a plurality of movable nozzles which can traverse the rack and means for supplying hot water under pressure to the nozzles, the water is heated by a gas heater and may be manually directed either straight to the spraying nozzles, or by way of a detergent ejector. Water from a pressure main 18 is heated in a gas heater 17 from whence it passes through a pipe 19 controlled by a main valve 20 to a two-way valve 21. In one position of the valve 21 the hot water passes through a pipe 22, non-return valve 28 and pipe 23 to reaction rotary sprayers 15, 16 mounted in the dish-washing machine cabinet above and below a dish and crockery rack 11, and passes through a strainer 12 into drain pan 13, to outlet 14. In the other position of the valve 21 water passes through a pipe 25 through a venturi ejector device 26, which draws in detergent solution from a container 24 by a pipe 27, the water and detergent then passing through the valve 28 and pipe 23 to the sprayers 15, 16. A pipe 29 supplies water to the container 24 if solid or powdered detergent is used. The pipe 29 may be connected with the pipe 22 so that the detergent supply is replenished while rinsing is being effected. Alternatively the container 24 may be supplied with water from the main 18 through a suitable manually controlled valve. When the water heater 17 is integral with the dish-washing machine as shown in Fig. 2 a separate hot water outlet may be provided to render available a supply for other purposes when the machine is not in use. The upper part of the cabinet 10 is provided with a door, arranged to open downwards to form a temporary stand for articles to be washed, and having a port hole to allow of inspection of the washing operation. In a larger machine. Fig. 3. two cabinets 30, 31, are arranged side by side, with sliding doors 34, 35, 36 in their sides. The first cabinet 30, is for washing and the second, 31, for drying, the heat therefore being supplied by the flue of the water heater. A dish rack pushed into the washing cabinet is made to push a rack already therein into the drying cabinet which latter rack pushes a rack of dried dishes from the drying cabinet. A continuous washing and drying operation can therefore be performed.

Abstract: 951,384. Seaming non-metallic sheet material; splitting webs. NATIONAL DISTILLERS & CHEMICAL CORPORATION. Sept. 19, 1961 [Sept. 26, 1960], No. 33582/61. Headings B4B and B5K. [Also in Division F2] A method of continuously forming a plurality of lay-flat tubes of thermoplastic material from a single flattened tubular web of the material comprises drawing the flattened web through a substantially planar path; slitting the web along a line parallel to the longitudinal edges thereof to form at least two sections; heat-sealing the slit edges of each section; and cooling the sealed edges of each section to set the seal. The flattened tubular web 235 preferably of a thickness between 0.5 and 2 millimetres passes either from a feed roll or from a production source to the apparatus in which it passes over idler rollers 210, 220 between rollers 47, 27 over a forming plate 69 supported on rods 67a, 68a and having a slot 69a therein, between rollers 46, 30 and over idler rollers 230, 240 to a take-up roll (not shown). The driven roller 30 is connected to a source of cooling water. The rollers 46, 47 covered with rubber or like resilient material are adjustable by hydraulic cylinders 42 to attain a tension in the web of between 0.25 and 0.5 1b. per square inch. A knife blade 90, a sealing wire 101 and a cooling blade 200 are mounted on a channel support member 81 pivoted on a rod 66 and which is initially held in a raised position suspended on a support-rod 87. After the web 235 has been threaded through the apparatus the member 81 is lowered so that the knife 90 slits the web continuously and the wire 101 and the blade 200 seal and cool the slit edges. The knife 90 is mounted on an arm 97, Fig. 3, on a block 92 slidable in a block 91 secured to the member 81 to enable the position of the knife to be adjusted. The sealing wire 101 extends beyond the end of dielectric holders 102 for connection to leads 101a. The holders 102 are held in bores in an arm 103 pivoted at 105 and adjustable by a nut 111 to alter the position of the wire 101 which is heated to between 1300 F. and 1500 F. The cooling blade 200 is of wedge-shaped crosssection and has an inlet 202 and an outlet 203 for circulating a cooling fluid preferably of a temperature between 60  and 70 F.

Abstract: 1397276 Teleprinter circuits GERATEWERK KARL - MARX - STADT IM KOMBINAT VEB MESSGERATEWERK ZWONITZ VEB 18 July 1972 33613/72 Heading H4P A receiving relay 6 at a local teleprinter subscriber's station permits reception from a remote station only if it receives two signals which indicate respectively that the remote station is transmitting and the local one is not. A signal received at EL to indicate that the remote station is ready to receive, turns on T1 and T2 thereby connecting the receiving relay 6 to the lower battery terminal, and also turning on T4. T4 being on enables a transmission control relay 9 to be energized by closure of a transmission key 10, and to be subsequently held on by 9.1, and turned off when necessary by a "cancel" contact 11. Relay 9 has normally closed contacts 9.2 which normally short out a punched tape transmitter terminal 1 and a "duplex teleprinting magnet" 3, so that energization of relay 9 permits transmission from 1 to pass through a single current-double current converter 4 to transmission terminals SL. When a distant transmission is to be received, a low polarity is placed on SL and is applied through R8 to turn on T2 so that relay 6 can be energized (via T2) by the received signal. When a particular (high) signal from the remote station appears at EL (during transmission to that station) to stop transmission from 4 for fault or other reasons, T1 turns off and thereby turns off T4 to de-energize relay 9 and stop the transmission at 9.2, and also turns off T2 to de-energize relay 6.

Title: Method of forming sand mould
IPC: B22C15/12
Filed: 1971-07-19
Abstract: 1324467 Foundry moulding machines and processes S P O Inc 19 July 1971 [20 July 1970] 33797/71 Heading B3F A foundry moulding machine comprises a flask support 8 and a presser head 3 provided with a plurality of presser or peen feet 6 mounted in cylinders at the end of hydraulically operated pistons 5. The presser head is reciprocable by a piston and cylinder 1, 2 towards and away from the flask support 8. In operation, pressure fluid from a reservoir 17 is pumped into a manifold 11 which supplies all the cylinders in a peen feet supporting block 4, thereby to move all the peen feet to their fully extended positions as in Fig. 1a. The presser head 3 is lowered on to a flask 7 to compress sand 10 therein. Firstly, all the peen feet move downwards to the same extent. As the presser head is further lowered (see Fig. 1c) some of the peen feet are forced back into the supporting block 4 in accordance with the degree of compression of the sand under each of the peen feet. As a result the hydraulic fluid pressure in the manifold 11 increases as the fluid is retained by a check valve 14 (Fig. 1a). When a predetermined pressure is reached the check valve 14 opens to return the fluid to the reservoir 17. The presser head is retracted and the finished mould part removed. The manifold 11 is divided into two parts, one supplying the cylinders of the peripheral peen feet and the other the central peen feet cylinders. In this way the compaction of the mould periphery can be increased relative to its centre.
