Abstract: 331,077. Thurston, A. P., (Dryice Equipment Corporation). June 13, 1929. Hopper-aavd-plunger machines.-Liquid carbon dioxide is expanded in a chamber 4 to make snow; the snow is kneaded by tamps 30, 31 of small area and the tamped snow is compressed to form blocks, the directions of 'tamping and compression being different. Gas evolved escapes through a screen 7 to the space surrounding the collecting bin 20 and tamping and compression space 21, and is afterwards exhausted. The tamps are reciprocated by hand or mechanically and release entrapped air and gas. After the tamping a. plate 23 is slid across the bottom of the hopper, closing the space 21 in which a head 22 reciprocated by a power cylinder, screw or other motor means compresses the snow. To compress the first block a plug is inserted; afterwards each block x as formed is pushed to the position x<1> to form an abutment for the succeeding block. Fingers 27 may be provided to sustain part of the thrust pressure and may assist in separating the formed blocks. The slide 23 may be advanced and the piston reciprocated several times to increase the density. The blocks are removed by a conveyer 28.

IPC: H04B1/16
Filed: 1925-07-17
Abstract: 242,948. Western Electric Co., Ltd., (Assignees of Holden, W. H. T.). Nov. 13, 1924, [Convention date]. Thermionic valves, arrangements and connections of.-The high and low tension supply to valve receiving or transmitting sets is derived from a common source such as the electric light supply mains. The plate voltage, grid-bias, and filament supply is taken from a single rectifying unit, though certain of the valve filaments are energized from a separate transformer unit and the space current flowing through these valves is used to augment the filament supply to the rest. The Figure shows a superheterodyne receiver, local oscillations being supplied from a back-coupled valve O1 to the first detector D1, the output from which passes through one or more intermediate amplifiers A1 to a second detector D2, and thence through a push-pull amplifying stage A2 - - A5 to the loudspeaker 24. The midpoint 6 of the frame aerial 1 and one of the outer terminals are connected across the grid and filament of the first detector D1, the plate of which is connected to the other frame terminal through a stabilizing condenser 5. Energy from the mains L1 feeds two transformers 25, 26 in parallel. The transformer 25 feeds the filaments of valves A2 - - A5 direct through conductors 28, 29 and 30, 31. The transformer 26 feeds the full-wave rectifying unit R1, R2, through a main winding 33 and an auxiliary winding 32 which energizes the filaments of the rectifying valves. A blocking circuit 34 and smoothing circuit 35 prevents the passage of current irregularities into the set. The rectified voltage is fed to the plates cf the amplifiers A4, A5 by a conductor 36 through a potentiometer 48, and to the plates of the amplifiers by a lead 46 through the windings 47. The tubes D2 and A1 are fed from potentiometer 38, 40 through the transformer primaries 39, 42 whilst the supply to the oscillator 01 is'taken off from the point 43. Grid bias is supplied to the amplifiers A4, A5 through a conductor 52 and balanced resistances 53, to A2 and A3 through a resistance 54, conductor 55, the filaments of tubes D2, 01, and A1, and conductor 56 to the balanced resistances 57, and to the tubes A1, D1 and 01 through resistance 54, conductors 55, 58 and 8 and through the respective transformer windings to the grids. The filament supply to the tubes D2, A1, D1 and 01 is derived in part from the space current flowing through the amplifiers A2--A5 through the leads 28 - - 31 to the midpoint of transformers 15, thence through lead 12 to the filaments of D1 and A1, through conductor 10 to the filament of 01, then to D2 and back through resistance 54 to the negative side of the rectifier R1, R2. The rest of the filament supply to these tubes comes direct from the rectifier through conductor 36 to point 37 and then through the resistances 38 and 40 in parallel to the conductor 12 which supplies the tubes D1, A1, 01 and D2 in series.

Filed: 1957-06-12
Abstract: 860,894. Valves. SPEZIAL TECHNIK ET. June 12, 1957 [June 19, 1956], No. 18480/57. Class 135. [Also in Groups I, VI and XI] In a coffee beverage making machine (see Group VI) having an air heater associated with a coffee roaster, air is supplied from a fan to a valve 15, Fig. 4, where it passes through apertures 66 in a regulating sleeve 65 into a ring space 67 communicating with an air canal 16, leading to an air heater, or into a second ring space 68, communicating with a by-pass canal 21, or with both spaces 67, 68 or with neither. Sleeve 65 is connected to an armature 69 controlled by an electromagnet winding 70. A sleeve 73 is connected to a pin 72 slidable in a fixed tube 71 biased by spring 74, its position being determined by a Bowden cable 75 connected at one end to the pin 72 and at the other end to control rollers 76, Fig. 5. The latter runs on a control surface, whose position is adjustable by knob 77 to control the axial position of the pin 72. A spring 80 tends to shift the armature 69 downwards relative to the sleeve 73 until a shoulder 78 of sleeve 73 engages a shoulder 79 of armature 69. When winding 70 is fully energized, armature 69 is pulled up fully and air is supplied to canal 16 only. When the voltage across the winding is reduced, armature 69 is forced downwards until shoulders 78 and 79 engage when air will be fed to both canals 16 and 21, the proportion depending on the setting of knobs 77. When winding 70 is de-energized armature 69 drops so that no air is supplied to either canal 16 or canal 21.

Title: Improvements in or relating to motion picture projectors
IPC: G03B21/46
Filed: 1950-07-25
Abstract: 689,500. Kinematograph projectors. INTERNATIONAL PROJECTOR CORPORATION. July 25, 1950 [Nov. 25, 1949], No. 18541/50. Class 97 (i). A device for synchronizing the shutter rotation and film feed comprises a shutter shaft with an external helical spline and an internally-splined member engaged with the external spline and axially adjustable thereon and having permanent driving connection with a gear journalled on the untoothed part of the shaft. Fig. 2 is a side elevation of one form, Fig. 4 being a horizontal section at. the axis of the shutter shaft. The projector mechanism has a single vertical driven shaft carrying spiral gears which drive the top and bottom continuous feed sprockets and the intermittent feed mechanism. Another of these gears meshes with a gear 14 on the shaft 15 carrying the dished shutter 44. The gear is rotatable on the shaft but is located axially between the end bearing and the end of an enlarged helicallysplined portion 48. A member 52 carries a mating internal spline and is secured to the end of a tubular member 49 on which a ball-bearing 56 is secured by a nut 61. Two rods 54 project axially from the member 49 through bores in the gear 14 and provide the driving connection to the shutter shaft. The outer race of the bearing 56 is retained by a plate 60 in an annular portion 57 depending from a member 58 secured to a sliding rod 59 and also guided by another rod parallel to it and carrying a spring which urges. the member to the right. Movement of the member 58 produces a relative axial movement of the splined members to provide an angular adjustment of the shaft 15 and the shutter relatively to the driving gear 14. The member 58 carries a transverse pin 66 engaged by the forked end of one arm of a bell-crank 67, the other end of which bears on a gear 75c forming the top end of a plunger 75. The projector mechanism is provided with a framing adjustment of the kind where the Maltese Cross mechanism is rotated round the intermittent sprocket. The mechanism carries a spiral cam with which the follower 80, on the plunger 75 is maintained in contact by the spring 77. Operation of the framing adjustment thus causes a simultaneous adjustment of the shutter timing. An over-riding initial adjustment of the shutter timing is also provided. For this purpose the main part of the plunger 75 is threaded internally to receive the screw 75b on the end of which the gear 75c is carried. This is rotated through a meshing gear 89 on a spindle 87 carrying the knurled head 90. The main part of the plunger 75 is prevented from rotating by the shank of a screw 78 engaging a groove 79. The extent of movement of the spindle 87 is limited by a nut 94 carried on a screw-threaded portion, the nut being prevented from rotating and being limited in axial travel. Accidental rotation of the spindle 87 is prevented by friction provided by a spring 91.

Title: Improvements in the manufacture and production of urea
IPC: C07C273/04
Filed: 1921-07-11
Abstract: In the manufacture of urea by forcing a mixture of ammonia and carbon dioxide into an autoclave, the gases are brought to the necessary pressure by expelling either or both of them from solutions capable of giving them off, by means of heat.  By way of example, a concentrated solution of ammonium carbonate or carbamate is forced into a heated column, the gas mixture produced passed through a cooler at about 110-150 DEG  C., and the condensate run into an autoclave where it is heated at 130-150 DEG  C. until the conversion into urea no longer proceeds.  The autoclave may be filled and discharged either at intervals or continuously, or the process can be carried out with single charges, when the column is replaced by a pressure-resisting vessel.  The unconverted gases are expelled from the urea solution and used, together with fresh gases, to saturate the exhausted liquid from the column for further use.  The gaseous ammonia and carbon dioxide may be generated in separate columns, for example, from aqueous ammonia and sodium or ammonium bicarbonate solution respectively, or one of the gases may be forced into the autoclave by means of a compressor.

Abstract: 531,180. Echo sounding apparatus. HUGHES, A. J., and HUGHES & SON, Ltd., H. June 28, 1939, No. 18820. [Class 118 (ii)] The operations of an echo sounding recorder may be indicated by one or more repeaters at a distance, the arrangement being such that recording and indicating may take place simultaneously or either may occur alone. The recorder shown is provided with changespeed gearing 21, 22 by operation of which from a control switch 65 the rotations of the constant speed motor 1 are conveyed to a shaft 24 at either of two speeds or are not conveyed at all, in which case the recording mechanism proper consisting of a pen 39 sweeping during its rotation about the shaft 24 across the record sheet 41 is not actuated. The motor, however, constantly drives a shaft 10 carrying cams controlling switches 15-18 so that, provided a multi-pole switch is thrown, a repeating indicator which may be of the kind described in Specification 478,744 is actuated. An electrical lay-out is described and includes an amplifier, connections for suppressing the effect of the sound transmission upon the recorder, the multi-pole switch above-mentioned and the control switch 65 with its geared auxiliary switch 67, both these switches controlling spring sets individually connected with similar sets controlled by the cams 32, 52 for timing the various operations. With the control switch in one position, the latter cams are not driven and the repeater is operated under the control of cams 11-14 provided the multi-pole switch is in closed position. If the control switch is moved one way or the other, the functions of cams 11-14 are taken over by cams 32, 52 and the recorder operates in one or other range while the repeater may be left connected up or may be cut out.

Abstract: 748,432. Valve circuits. SCHULTZ DIE CASTING CO., and TRIGGS, W. W. July 8, 1948, No. 19041/51. Divided out of 748,431 [Group XXII], under which a Specification was laid open to inspection under Sect. 91 of the Acts, June 11, 1949. Class 40 (6). A power supply system for a valve circuit produces a grid bias supply by rectifying the output of a transformer fed from the secondary of the transformer supplying the H.T. voltage, a smoothing choke coil being provided in the bias circuit and having contacts associated with it which cause the secondary circuit of the H.T. transformer to be interrupted when the bias fails, a further transformer being provided in a circuit with a switch which controls the energization of the H.T. transformer. A series of thyratron valves 1, 2 &c. derive an A.C. H.T. supply from the left-hand winding of a transformer 465 and their D.C. bias from a rectifier 553 connected to a transformer 475 fed from transformer 465. The bias circuit includes a relay 499 the contact of which controls a relay 430 having a contact 503 in series with the H.T. supply. Relay 499 is slow to operate so that the H.T. is not connected until after a period sufficient for the valves to warm up but is quick to release so that if the bias fails the H.T. is immediately disconnected. Energization of transformer 465 is controlled by a switch 454 controlling a relay 456 having contacts in the main A.C. supply circuit 90, 91.
