Title: Improvements in kinematograph apparatus
IPC: G03B21/32
Filed: 1937-01-27
Abstract: 489,615. Gramophones; associated working with kinematograph apparatus. HOBBS, E. W. Jan. 27, 1937, No. 2435. [Class 40 (ii)] [Also in Group XX] In a combined kinematograph projector and gramophone in which the kinematograph images are carried in rows on a sheet supported on a drum which is intermittently moved longitudinally to project the images in a row, is automatically rotated at the end of each row, and is then moved back intermittently to project the images on the next row, means are provided to synchronize the starting of the sound reproduction and the picture projection. The kinematograph apparatus, housed in a chamber 121, is driven from an electric motor 130 through a clutch 129 and a shaft 125, the motor also driving the turntable 132 of the gramophone. The picture drum 60 which is intermittently moved along the shaft 62 carries at each end pins 133 to engage a pivoted lever 135 connected to a bar 136 adapted to engage the end 141 of the pivoted sound pick-up arm 138 which also carries an extension 142. The operation of the apparatus is as follows. The picture sheet is placed on the drum 60 and is held by a retaining member which, initially, is opposite the projection aperture. Since the drum is in its extreme end position the pin 133 has depressed the lever 135, which is held by a spring latch so that the sound arm 138 is raised. The motor 130 is started and since the clutch 129 is disengaged the disc 132 rotates alone until a projection 150 on the disc engages a movable cam surface 151 connected by a link mechanism to the clutch 129 which is thereby engaged to start the kinematograph apparatus. The drum is accordingly fed intermittently across the projection aperture without projection taking place and an extension 144 on the drum engages the extension 142 to move the pick-up arm at the beginning of the record. When the drum reaches the end of its travel it is rotated by the fixed cam to bring the first row of images opposite the projection aperture, the pin 133 is disengaged from the lever 135 and the pick-up arm is thereby lowered on to the record and simultaneous projection and sound reproduction commences.

Patent GB-953410-A (GB)
Title: Process for the manufacture of phosphates and phosphatic fertilizers
IPC: C05B11/12
Filed: 1961-01-23
Abstract: A process of manufacturing substantially calcium-free phosphates from phosphate rock includes the steps of reacting phosphate rock with an acid, particularly hydrochloric acid, to produce a solution containing primary calcium phosphate, with evolution of gaseous by-products, treating the solution thus obtained with ammonia and carbon dioxide added simultaneously, with or without the addition of potassium or sodium chloride, to convert the primary calcium phosphate to primary ammonium, potassium or sodium phosphate, while maintaining the pH value during this treatment between 5 and 7 to ensure maintenance of the major proportion of the resulting phosphate in the water-soluble state and precipitation of substantially all of the calcium present in the form of a carbonate, separating the solution containing the primary phosphate from the precipitate and recovering a phosphate product from the solution.  When the acid digestion is carried out using hydrochloric acid the separated solution of primary phosphate also contains ammonium chloride, which may be recovered from the solution in gaseous form by heating and subsequently reacted with nitric acid to produce ammonium nitrate (a fertilizer ingredient) and gaseous hydrochloric acid which after water scrubbing may be recycled to the process.  If the product phosphate is a potassium phosphate it may be either the primary or the meta phosphate (i.e. KH2PO4 or KPO3) depending on the temperature at which ammonium chloride is driven from the solution, the meta phosphate being produced at higher temperatures.  If the separated solution contains primary ammonium phosphate it may be treated with further ammonia to raise the pH to between 8 and 9, resulting in secondary ammonium phosphate or a mixture of secondary and tertiary ammonium phosphates, which may be precipitated while leaving ammonium chloride in solution. The calcium carbonate precipitate from the reaction may be treated to recover any secondary calcium phosphate present therein.  Secondary calcium phosphate may also be produced by reacting recycled hydrochloric acid with phosphate rock to form a solution containing primary calcium phosphate which on reaction with calcium hydroxide yields the secondary phosphate.  When the gaseous by-products contain silicon fluoride they may be scrubbed with water to form fluosilicic acid which on reaction with a chloride of sodium, potassium or magnesium produces the corresponding fluosilicate and gaseous hydrochloric acid.  Typical fertilizers made from the products of the above process are combinations of primary and/or meta potassium phosphate with ammonium nitrate (which may have been further ammoniated).  A specific mixture mentioned is three parts of primary potassium phosphate with ten parts of ammonium nitrate, the resulting fertiliser containing 23.2% nitrogen, 17.6% P2O5 and 11.7% K2O as useful fertilizer components.

Abstract: 414,085. Claw clutches. ASSOCIATED TRANSMISSIONS, Ltd., and HINGSTON, W. H., 40, Grosvenor Gardens, Buckingham Palace Road, London. Jan. 27, 1933, No. 2652. [Class 80 (ii).] In a claw clutch, projections carried by one clutch member co-operate with grooves or apertures on the other clutch member of such relative dimensions that a spring urging the clutch members into engagement is prevented by the time element involved in the operation from bringing the projections into operative relation with the grooves or apertures so long as there is any material relative rotation of the two clutch members, while the latter may be disengaged under any conditions. As shown in Fig. 1<a>, spring-loaded balls E carried in radial pockets in one clutch member C co-operate with longitudinal grooves K in the other clutch member G, the grooves K leading through a ramp J from an annular groove I. As shown in Fig. 3, longitudinal projections R<0> on a conical ring R held by springs S in frictional contact with a conical part of one clutch member P co-operate with apertures N<0> in the other clutch member N.

Title: An improved method of and means for molding artificial teeth
IPC: A61C13/08
Filed: 1930-01-25
Abstract: 349,589. Moulding artificial teeth. DIMELOW, T. E., 431, West Springettes. burg Avenue, York, Pennsylvania, U.S.A. Jan. 25, 1930, No. 2671. [Class 81 (ii).] In a process for moulding artificial teeth, in the manner described in Specification 254,075, [Class 81 (ii), Medical &c. appliances], wherein the body porcelain is first moulded and biscuited, and the light coloured enamel porcelain forming the incisal edge and covering only the central and incisal portions of the labial surface is then moulded thereon, the cervical end of the tooth is pressed between mould surfaces of identical form throughout both the moulding steps. The mould used in the final step may be an ordinary two-part mould, Fig. 2, fine surface markings having been obtained on the part 3 by pressure with a hardened steel master tooth model or die in position in the mould recess. A second and identically marked upper portion 3a is formed by pressure with the same die and is then cut away to the form shown in Fig. 3, leaving only the cervical portion 5 of the tooth moulding recess. The recess is then completed, in the form necessary for moulding the body portion of the tooth, by attaching a shaped metal bar 6a, Fig. 4, in the cutaway portion 9 of the mould 3a. The bar 6a is secured by a wedge 11 or by a screw 12 or by both means. In a modified process, instead of using the part 3, Fig. 2, for the final moulding step, the bar 6a is removed from the mould 3a and replaced by a bar serving to complete the moulding recess in the form of the complete tooth, pressure with the master tooth die being again employed to give the desired surface markings on the bar. In either modification of the process the assemblage comprising the parts 3a, 6a, Fig. 4, may be replaced by a one-piece upper half mould casting formed by using the assembled parts as a pattern. The surface markings may be formed on the part 3a after the bar 6a has been secured thereto by employing a tooth die which has been ground away to the form of the body portion of the tooth.

Title: Improvements in or relating to call recording apparatus for use in telephone systems
IPC: H04M1/57
Filed: 1929-01-26
Abstract: 328,324. Pollak, J. E., (Associated Telephone & Telegraph Co.). Jan. 26, 1929. Automatic exchange systems.-A subscriber on 'leaving his telephone may operate a switch 1 to connect apparatus to the line by means of which a record of the incoming calls is made on a paper strip under the control of impulses dialled by the calling party and repeated at the exchange. When the line is called, ringing current from the exchange passes through relay 5, which attracts its light armature 9 and shunts condenser 7 in its circuit, thus simulating the reply of the subscriber, whereupon the ringing current is replaced by direct current and relay 5 energizes fully and attracts armature 10, which releases gear-wheel 32, strikes armature 9 and engages a locking pawl 38 so that both armatures are held operated independently of relay 5. Wheels 32, 33, 34 and 31 and the paper feed rollers are geared together, and the pair of wheels 31, 32 make a revolution in the same time, while wheel 34 rotates rapidly and by intermittent short-circuiting at contacts 22, 23 of coil 20 in the line circuit sends back an audible tone to notify the calling subscriber that the recording apparatus is ready to receive his number. Dialled impulses are now received by relay 5, the armature 26 of which carries a stylus 29 for making a record of the number on the paper strip 30. After wheels 31, 32 have made a complete revolution, cam 35 strikes locking pawl 38, opening contacts 17, 18 to release relay 5 in case the calling subscriber has not hung up; and allowing armature 10 to fall back and stop the rotation of the gear-wheels and the paper feed rollers. In a modification, a sluggish relay is employed in the line circuit in series with a separate impulse-responding relay, and the apparatus for locking armature 10 is then unnecessary.

Abstract: 459,621. Electrically - controlled fastenings. HENDERSON, R., 26, Lanercost Road, Tulse Hill Park, London. March 20, 1936, No. 2832. [Class 44] [See also Group XXXVI] A removable multiple-coupling key-member for interrupting the circuits of the controls of a door fastening mechanism for safes, motor vehicles, &c. comprises an insulating member carrying interconnected studs arranged to engage spring plungers mounted in the surface of a socket or other fitting adapted to receive the key-member, some of the plungers being connected to the circuits to be interrupted. A row of plungers 25 coacting with studs 23 on the key-member 17 are some of them connected to leads 51, the remainder being in electrical connection with metal strips 39, 40. Another set of plungers 29 are connected some of them to leads 50 and the remainder to metal strips 33, 34. The sets of studs 21, 23 on the key-member are connected together by conductors 20 housed in a cavity in the member, in such a way that circuits are completed through the leads 50, 51 but no connection is made between such of the studs as engage plungers connected to the strips 33, 34, 39 40. These strips are connected in an alarm circuit or a circuit that throws the door operating circuit out of action, so that an attempt to complete the operating circuits by means other than the proper key-member will result in a signal being given or the operating mechanism being locked. The circuits completed by the key-member lead to a reversible motor 60, Fig. 6, by which a door-bolt 66, 67 is operated. A reversing switch 61 is employed in connection with bridging contacts 68, 69 carried by the bolt so that the correct circuit is closed to move the bolt to its opposite position. A tapping switch 77 is also provided to ensure that the key-member does not itself close the circuit, so that the operative plunger contacts cannot be identified by their discoloration by arcing.

Filed: 1933-01-30
Abstract: 401,139. Making helical tubes. FERGUSON, A. G. H. and FERGUSON, M. J., Gordon Street, Footscray, Victoria, Australia. Jan. 30, 1933, No. 2857. [Classes 83 (ii) and 83 (iv).] Angular bending; coiling; uniting by fusion.- In making heavy gauge lap welded helical steel pipes a plate is coiled by feeding it tangentially into a cylindrical forming ring through a longitudinally disposed entrance mouth therein. The strip B is drawn over a table T under scrapers 14 and under guide plates 13, 18 and edge rollers 12, 18a, by driven rolls 16 which have shaped edges to form spigots and faucets at the opposite edges of the strip as shown in Figs. 4 or 5. The rolls 16 which may be milled to increase the grip are under hydraulic pressure. The strip is fed tangentially through the entrance 19 of an obliquely arranged ring FR which is carried by a housing 21 angularly adjustable on a pivot 23 by adjustable stay rods 24, so as to vary the pitch of the helix and thus the diameter of pipe. The ring is anchored by a rod 25 pivoted over the axis 23 and hooked to a bar 27 secured to the roll housings 17. The ring is provided at its mouth with a liner 28 so as to produce an initial curvature of less radius than that of the finished pipe, the plate expanding elastically to its ultimate radius while still in the ring. A scraper 29 is provided in the ring to clean the outer surface of the plate to reduce friction in the ring. The plate is supported during coiling by an internal roll 31. The coiled helical tube on emerging from the ring is received on rollers 35 mounted on angularly disposed parallel plates. When the required length of pipe emerges from the forming ring it is cut off and is then welded by passing under one or more welding heads over a series of pairs of driven rolls 36 arranged on pivoted arms 37, which are angularly adjustable by a common rod 37a to suit the pitch of the helix. The pairs of rolls are geared to each other by chains, one roll of each pair being universally jointed to the corresponding roll of each pair and driven from a shaft 41. The pipe is raised or lowered from the rolls by pairs of rolls 42 mounted on shafts which are vertically moved in guides by links and bell cranks from a common rod 48.
