Abstract: 974,812. Screw and nut gearing; valves. YARNALL-WARING CO. March 7, 1961 [March 11, 1960], No. 8208/61. Headings F2Q and F2V. In mechanism producing linear motion of a member, such as a valve stem 15, in a sealed housing by rotation of an external member such as a handwheel 46, the stem 15 is surrounded by a flexible non-rotatable sealing tube 21, e.g. of stainless steel, whose upper end is closed by a plug 22, whose lower end is welded to the valve body 10, and whose inner surface is provided with a screw thread or with rings 35 eccentrically engaging a part of the periphery of a smaller diameter screwthread 34 on the stem 15, relative linear movement being obtained by gyrating the non- rotatable tube 21 at two or more points in its length so that the points of engagement between the threads 34, 35 are progressed around the circumference of the stem 15. As shown, the gyrating or flexing is obtained by securing the tube 21 to the inner races of two bearings 39, 40 whose outer races are eccentrically secured in a rotatable casing 43 which carries the hand wheel 46 and is mounted in bearings 48, 52. The interengaging screw threads 34, 35 may be of the same or opposite hand and one of them may have a zero helix angle, i.e. comprise the rings 35 shown. In a modification the tube 21 is gyrated by three eccentric bearings in a rotatable casing. In a further modification the tube is flexed to a helical formation by a series of closely spaced eccentric bearings to provide a continuous helical contact path between the screwthreads. In an alternative arrangement, Fig. 6 (not shown), the valve stem is hollow and has an internal thread partly engaged by rings on the exterior of a non-rotatable flexible tube of smaller diameter, the tube being flexed by a rotatable S-shaped rod mounted therein and secured to an operating hand wheel. The valve shown comprises a disc 14 removably secured to the stem 15 by a key 32 engaging a keyway in a fixed guide 25, the body 10, tube 21 and guide 25 being secured together by welded connections.

Title: Improvements in and relating to recovery of fat from animal fat containing portions
Inventor: PERCIVAL ROBERT CLARK
IPC: C11B1/00
Filed: 1954-03-22
Abstract: Fat is recovered from animal fat-containing parts by subjecting them to high frequency vibrations to crack the fat globules having cellular envelopes and thereby release the fat. The animal parts are treated preferably at their animal heat, about 37 DEG C., by separating the parts immediately from slaughtered animals.  The parts are hashed in a hasher, preferably provided with heating means, such as a steam jacket, to maintain the animal heat temperature.  The hashed material is then subjected to the vibrations, the temperature being further controlled during this step so as to keep the released fat in the liquid state and below the coagulating point of the proteins therein.  Warm water or salted water, at about 37 DEG C., may be added to the fat-containing parts during the hashing step in the proportion of 20 to 30 per cent of the weight of the fat material.  The high frequency vibrations are preferably effected by a multi-stage high frequency vibrator having an inlet and outlet and wherein the frequency of the vibrations increases from the inlet to the outlet.  The method may be applied to fat stored in freezers by first defrosting and then heating up to 37 DEG C.

Abstract: 355,181. Exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm.-(Assignees of Blomberg, K. H. ; 39, Lokattsvagen, Appelviken, Sweden.) March 19, 1931, No. 8512. Convention date, March 21, 1930. [Class 40 (iv).] A calling subscriber at a prepayment station is first connected to the wanted subscriber through a thermionic valve, so that he can hear but cannot talk, the valve being cut out to permit two-way conversation when the prepayment device is operated. Relays SRI, SR2 energize when the subscriber calls, lighting the lamp AL, which is extinguished by the energization of relay BR when the operator plugs in. The operator sets up the call and throws the ringing key EOR, whereupon relay SPR energizes over the sleeve circuit and locks, switching the valve E into the connection and supplying filament current and grid bias voltage thereto from the exchange battery. When the prepayment device 13 is operated e.g. by the dropping of a coin, the insertion of the resistance r releases relay SR1, and relay SPR falls back due to the short-circuiting of its holding winding, removing the valve E from the connection. In a modification applicable also to automatic working the valve is switched in by the reply of the called subscriber. The application to a local battery system is also described. Instead of being individual to the calling line as shown, the valve may be included in the cord circuit.

Patent GB-638955-A (GB)
Title: Improvements in and relating to extrusion processes and apparatus therefor
IPC: B29C48/94
Filed: 1948-03-25
Abstract: 638,955. Lubricating extrusion dies. CANN, J. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 25, 1948, No. 8798. [Class 87 (ii)'] A rod or tube of thermoplastic or thermosetting material is extruded from a die 8 and is forced through a tube consisting of several sections or a compressed helix, while lubricant under pressure is supplied to the material through the spaces between the sections or the turns of the helix. The tube may taper, to allow for contraction of the material. The sections may be longitudinal or transverse, e.g. rings 1. The material may be given its final shape either by the tube or by an intermediate tube which may also be lubricated. To ensure even circulation of the lubricant, the abutting edges of the rings may be bevelled to form channels which are deeper near the extrusion die. Thin layers of felt or porous metal may be placed between the sections. The rings 1 are enclosed in a tube 2 surrounded by a jacket 10. The tubes may be formed in several units, e.g. A, B, each being supplied separately with lubricant, to enable a temperature or pressure gradient to be formed along the tube. The pressure decreases away from the die and the temperature may increase or decrease away from the die. To improve the surface finish of thermoplastic material, the material may be heated at the end of the tube. To prevent jerky extrusion a packing ring 36 is provided to offer resistance to the material. This resistance may be varied by means of a bush 35. An annular groove 37 having outlet ports prevents an excess of lubricant from reaching the ring 36. To give additional support to the extruded material, hot or cold extension tubes (Fig. 3, not shown), are provided between the end unit of the tube and the packing ring 36. When forming tubes, fluid under pressure may be supplied to the inside of the extruded tube and lubricant may be supplied through the core to the inside of the extruded tube. The lubricant may be soap, graphite, lubricating oil, air, oxygen, nitrogen, carbon dioxide or steam.

Title: Improvements in or relating to the control of electro-mechanical apparatus
IPC: B61L5/06
Filed: 1957-03-18
Abstract: 832,543. Operating railway points and other two-position mechanical apparatus. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. S.T.I.N. March 18, 1957 [March 17, 1956], No. 8837/57. Class 104 (1).  In a control equipment for the supply of energizing current to an electro-mechanical apparatus, the driven parts of which alternately change over from one fixed end position to the other in response to a current impulse, e.g. in the operation of railway points, the energizing circuit of the electro-mechanical device is closed under the control of at least two control initiating switches, e.g. press button switches, only if the operating positions of all the said initiating switches have first been taken up and subsequently at least two of said initiating switches have returned to their unoperated positions. In the embodiment described for energizing the machine 07 for reversing railway points by the operation of two press-button switches 08, 09 (not shown), closure of the front contacts 081, 091 of these button switches energizes an order-receiving relay 01 and the pick-up winding of a reversing relay 02 of the interlocking type. At front contact 013 and the non-interlocked front contact 021, the winding of a points position control switch 03 is energized over back contact 063 of a switchon relay 06, which assumes the position required to be taken up by the points and positions its change-over contact 031, 032 to select the energizing circuit of the device 07 accordingly. At front contact 011 a condenser 05 is energized and on the return of the button switches to their-unoperated positions, with the relay 01 returning to normal condition, the condenser is discharged through the winding of a time relay 04 over back contacts 012, 061, 082, 092 and the front contact 022 of relay 02 which is held operated. At front contact 041 the switch-on relay 06 is operated, opening its back contact 061 and closing its front contact 062 to bridge the series connected button switch contacts 082, 092 and maintain the time relay operated until the condenser 05 has discharged. At front contacts 064 and 065 the drive circuit for the machine 07 is completed over held front contacts 023, 025 of the interlocking relay 02. When the points are released, with the reversion of relay 02 to its unoperated position, back contacts 024 or 026 complete a supervisory circuit for the machine 07. Swiss Specification 294,857 is referred to.
