Abstract: 490,158. Automatic volume control. GENERAL ELECTRIC CO., Ltd., and BIGGS, A. J. June 10, 1937, No. 16169. [Class 40 (v)] In a delayed A.V.C. system, the distortion produced by variation of the impedance of the A.V.C. rectifier in shunt with the signal diode is prevented by superimposing on the constant delay bias, a bias proportional to the instantaneous amplitude of the modulation frequency envelope. In Fig. 2, AB is the constant delay voltage and GH the modulation frequency envelope. The A.V.C. rectifier 3, 4, Fig. 4, will become operative over the periods ab, cd of curve GH as shown, with resulting distortion. A.V.C. voltages developed across resistances 11, 12 and applied over lead C have superimposed thereon audio-frequency voltages of suitable amplitude and phase, derived from a convenient point in the audio-frequency stages of the receiver. These voltages are applied across resistance 12 over lead D and blocking condenser 13 and result in the hitherto constant delay voltage LM, Fig. 3, being converted to the form AB, which closely approximates to the curve GH; the latter curve does not cross the delay curve AB and the rectifier impedance, in shunt with the signal diode 2, 4 is maintained constant.

Title: Improvements in apparatus for producing continuous bodies of compacted material by extrusion
Inventor: HJULIAN JULIUS AUGUST
IPC: B28B21/38
Filed: 1951-07-09
Abstract: 688,448. Presses for separating liquids from solids; edge filters. CRANE CO. July 9, 1951, No. 16267/51. Class 46 [Also in Group V] Liquid is withdrawn by compression from a slurry of a material such as asbestos cement whilst it is extruded through a die, by means of narrow slits either in the wall of the die or, if a pipe is being made, in a mandrel. Fig 10 shows a mandrel comprising a hollow core 240 having radially spaced slits 252 communicating with an edge filter which is made up of a number of rings 248. The rings are chamfered towards the inside and are spaced from each other by lands formed on their side faces. The core 240 is provided with a longitudinal rib which engages in aligned notches formed in the inner periphery of the rings 248. The mandrel of Figs 19, 20 comprises a number of spaced bars 311 arranged around a hollow core 301 similar to that of Fig. 10. The bars are spaced by lands 320 and are clamped in position between a flange 315 and a screw-threaded ring 317. In the construction shown in Fig. 21 the mandrel 330 is solid and the filter is made up from rings 340, similar to the rings of Fig. 10, located in a recess in the wall of the moulding chamber 333. They are prevented from rotating by means of a locking bar 347. The water is forced from the slurry, through the rings, into circumferentially spaced chambers 349. The asbestos-cement slurry is fed by means of compressed air from a hopper to a hydraulic pressure cylinder. Pressure applied intermittently in the pressure chamber causes the slurry to be fed via pipe 73, Fig. 1, to a chamber 75 whence it is extruded around a mandrel 83. During the intervals in which pressure applied, the extruded pipe is gripped by means of a hydraulic brake 94 which resists extrusion and causes water to be forced out of the compressed slurry through the mandrel 83, or the walls of the mould, in the manner described above. Suction may be applied to the mandrel via pipe 80. During the interval of no pressure, the brake, still gripping the formed pipe, is moved to the right, releases the pipe, then returns to its former position where it again grips the pipe. At the beginning of the process it is necessary to surround the mandrel 83 with a tubular pressure-resisting member 115 until a sufficient length of pipe has been extruded around the mandrel. The brake comprises four circumferentially arranged gripping shoes 95 each actuated by a hydraulic piston 102 against the resistance of springs 96. A pipe 110 connects the brake to the slurry pressure-chamber so that it grips the pipe during the intervals in which pressure is applied to the slurry. The brake is reciprocated by a pneumatic cylinder and lever 145. Automatic actuation of the machine is ensured by means of limit switches and an auxiliary pneumatic system.

Title: Improvements in or relating to dividing materials into measured quantities
IPC: A01J23/00
Filed: 1924-07-08
Abstract: 244,140. Wade, H., [Knox Products Co.). July 8, 1924. Butter cutters; extrusion machines; streamcutting machines.-A parent mass of butter &c. is subdivided into smaller masses by confining the parent mass within a container to ensure extrusion in a predetermined direction, exerting extruding pressure, splitting and spreading the mass while confined into a plurality of columns, gradually diverging the columns while confined to an extent such as to prevent interference in severing, and finally projecting the columns beyond their confining walls and severing the smaller masses individually and in succession directly therefrom. The split and separated columns may be gradually reduced in cross-section and may be diverted into substantial parallelism before severance; further the parent mass may be compacted to fill out the container, ready for extrusion, by a unit action or singlestroke operation. A machine for carrying out the invention is described. The container G is furnished at its lower end with a cast tin die 1 comprising a cruciform rib 35a terminating in a splitting edge 35 forming four passages 36 which diverge and also taper downwardly and terminate in separated, parallel passages 37. The container is carried by a ring H, centred by a pin 29 and dowel 31, upon a gear D rotatably supported by a member C; and is supported at its upper end by a. ring F rotatably engaging a ring E fixed to supports 24 on the member C. A casing A enclosing the apparatus supports the member C on ledges 3 and a partition 2. The ring D is rotated by a gear 19 on a shaft 18 passing through the wall of the casing and operable in one direction by a handle 20. A piston 3, fitting the container H and rotatable therewith. is secured to a screw K working through a nut L on a bridge M having portions depending through openings in the ring E and terminating in pins 42 adapted to be engaged by cams 43, 44 on side pieces N pivoted to the ring E and operable by a handle 47. When the handle is raised the bridge M is free for withdrawal, and, after recharging the container, the plunger J, screw K, and bridge M are reinserted and the handle is depressed to compact the material by unit action. A stationary cutting-wire P, supported by an adjustable member 62 close to the die outlet, severs the extruded columns, the gears 19, D being proporrtioned so that each revolution of the handle 20 severs one column. The die passages 37 are rectangular and are so disposed that the columns are severed diagonally. Valves 52 vent the container upon withdrawal, of the piston J. The casing A is furnished with an aperture 99, closed by a door 101, for the passage of a dish V which is positioned by a depression 100; and is closed by a two-part lid movable on links. An ice receptacle R is housed within the casing; also a vessel for reserve charges for the container G. A weighted pawl O locks the gear D when the container G is removed for cleaning &c.
