The passages 37 may be circular, or flat, and the material expands on leaving the passages 37, to be cut by a rotating knife 41, which may be spring loaded against the plate. The die plate 29 and ring 25 are detachably mounted for cleaning, and the outlet passages 37 may comprise inserts which are replaceable upon wear, or to define different shape passages, or are replaceable by inserts not having passages to vary the extrusion pressure. In the embodiment, the female auger 12 is stationary and replaceably located in a barrel 11 at screws 14 and is tapered to effect an increasing compression on the material in the downstream direction and the male auger 22 is also replaceably mounted. The upstream surface of the boss 33 comprises radial saw tooth formations which assist flow of material between the auger 22 and passage 26 and effect a breaker action. The material is heated by the compression of the augers, and by passage 26, but the barrel 11 may also have heating means and temperature sensors may be located within the barrel or die. The size of recess 27 can be increased by a recess in the die plate 29, around the boss 33 which may be detachable from the remainder of the plate 29. The material is delivered to the inlet 20 of the extruder in finely ground form, via a screw conveyer and hoppers, and the material cut from die may be removed on a conveyer.

Title: Improved radio direction finding means
IPC: G01S1/02
Filed: 1940-10-21
Abstract: 543,873. Radio direction finding. REDIFFUSION, Ltd., and RINGHAM, G. B. Oct. 21, 1940, No. 15533. [Class 40 (v)] A main coil for determining the direction of a transmitter is associated with a vertical antenna for sense finding and with an auxiliary coil, switching means being provided for substituting the auxiliary coil for the main coil during sense finding which is effected by comparing the signal strength when employing the main and auxiliary coil. Main and auxiliary frame aerials 1, 2 are relatively fixed at right angles and are rotatable about a common axis 3. These aerials, together with a vertical antenna 4, are connected through ganged switches 6, 7, 8 to a receiver 5 so that in the left-hand position of the switches the vertical antenna 4 alone is connected to the receiver and in the right-hand position the auxiliary antenna 2 also is connected, whilst in the intermediate position the main frame aerial 1 alone is connected. The receiver 5 includes phase and amplitude adjusting means for use with the vertical antenna and also includes a meter 9 for measuring signal strength. In operation the main frame aerial 1 is switched into circuit and rotated until a minimum signal position is found. The frame aerial is then rotated a few degrees from this position so that a small signal is obtained. The vertical antenna 4 is then brought into circuit and the auxiliary frame aerial 2 is substituted for the main frame aerial 1. A decrease of signal strength indicates that the correct sense bearing is being obtained. The frame aerials 1, 2 may be replaced by the main and auxiliary search coils of a radio goniometer having fixed frame aerials. The apparatus may have means for applying synthetic radio signals for instructional purposes.

Title: Improved magnetic core storage apparatus
IPC: G11C11/06
Filed: 1962-04-24
Abstract: 991,713. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 24, 1962 [April 24, 1961], No. 15594/62. Heading H3B. Each unit of a storage matrix comprises two magnetic cores A, B both coupled with respective column and row conductors Y, X in the same sense and coupled in opposite senses with an output conductor S, the unit being cleared by applying coincident half-current pulses of one polarity to the associated row and column conductors to set both cores to a datum remanent state, while a binary digit is recorded by applying coincident pulses of opposite polarity and lesser magnitude to the row and column conductors at the same time as either one core has a single input conductor energized, or both cores have respective input energizations in opposite respects, so that one core is switched partially to an intermediate remanent state P and the other to a different partial state N. As shown, cores 10-17 and 18-25 are arranged in two groups of planes, and for writing or reading two-bit words a particular word line comprising two core units such as 10, 11 and 18, 19 is selected by energizing a column and a row conductor Y 1 , X 1  from column and row address and drive units 30, 32. The binary word to be stored is transferred from a data register 40 to trigger units 36, 38, the outputs " 1 " or " 0 " from each trigger unit respectively energizing one or other of two input conductors Z 1 -0, Z 1 -1, Z 2 -0, Z 2 -1 associated with the A and B cores. Assuming the cores to be in the datum remanent state initially, the application of coincident positive pulses to a selected row and a column conductor partially switches all the cores in the two selected units, one core in each unit being switched to state P and the other to state N, the lesser flux changes being due to negative magnetization by the energized input conductors. Thus, for example, with trigger units 36, 38 set to states " 1 " and " 0 " respectively, cores 10, 19 switch to state P and cores 11, 18 to state N. Read out is effected by coincident row and column pulses of negative polarity and larger amplitude which restore the cores to their datum state. Each pair of cores in a unit induces opposing pulses in an associated sense conductor S1 or S2, but since the flux excursions are different for the two cores, the output from the core in state P predominates, and its polarity in the sense conductor is indicative of the digit stored. In a modification a single input conductor is common to both cores A, B of a unit, and couples both cores in opposite senses so that switching of one core to state P and the other to state N depends on the polarity and hence the digit value of the input. Specification 783,918 is referred to.

Title: Improvements in means for the production of variable electric resistances
Inventor: ORAM JOHN ANDERSON
IPC: B21F3/00
Filed: 1960-05-03
Abstract: 975,132. Making spiral resistance elements; coiling; winding. RELIANCE CONTROLS Ltd. April 28, 1961 [May 3, 1960], No. 15604/60. Headings B3A and B3E. A machine for winding a spiral resistance element comprises a coiling head for coiling an elongated flexible, insulating core into a spiral, a guide adapted to guide the elongated core through a winding head to the coiling head and having an outlet mouth adjacent the coiling head, the winding head being adapted to wind wire about the core as it passes from the outlet mouth of the guide to the coiling head, and means for moving the guide and winding head in dependence upon the progressive increase in the diameter of the spiral in such a manner that the mouth of the guide moves substantially along a line radial of the centre of the spiral and that the length of core tangential to the spiral and extending to the mouth of the guide subtends a substantially constant angle at the centre of the spiral. A strip 44 of insulating ribbon passes from a reel 43, through a tubular guide 41 mounted on a carriage 34, to be wound spirally on to an insulating boss 22 fitted on a rotating head 21. Resistance wire 47, from a braked reel 46 carried by a head 45 rotated about the guide 41, is coiled, by a pulley 48 on an arm 49 on the head 45, about the strip 44 as it issues from the guide 41 to the head 21. The head 45 may be provided with a revolution counter. Interleaved with the wire around strip 44 as it winds to spiral form on the head 21 is a slightly wider insulating strip 24 which passes from a reel 23 over a magnetic clutch 26, which serves to provide a progressively decreasing tension as the spiral grows, around rollers 28, 29, on an arm 30 pivoted at 32, to the head 21. As the diameter of the spiral increases, by bearing on the roll 29 the spiral moves the arm 30 about the pivot 32 and thus, through a roller 62 on the arm 30 engaging the carriage 34, moves the carriage and thus the guide 41 away from the centre of the head 21. As the diameter of the spiral increases the linear speed of the strip 44 increases, thus increasing the pitch of the wire 47 coiled thereon. The head 21 may be given an additional rotation to modify the pitch of the wire on the strip 44, by cam means, by moving axially a helical gear, engaging a gear 19 driving the head. Switch means may stop the machining after the required number of turns of the spiral has been wound. To wind identical potentiometers the speed of the head 21 may be varied, to apply correction, under control of a master potentiometer. Adhesive may be supplied to both sides of the strip 24 from tubes 83, 84. Specification 975,131 is referred to.

The table is formed with a ring of openings above which are mounted the work-holders B. While the table is at rest, one half of the workholders are located above the nozzles, and the other half are at the front of the apparatus in position to allow the work to be changed. Rotation of the table through half a revolution transposes the two groups. The shaft A<1> of .the table carries a constantly rotating worm-wheel C, which runs loose, and a clutch D which is raised and lowered by a bridge D<1>. The bridge is supported in the raised position by two pivoted arms D<2>; these are pushed outwards at the required intervals, to liberate the bridge and allow the clutch to drop into engagement with the wheel, by cams d<3> carried by star-wheels d<2> which are rotated intermittently by lugs c<2> on the lower face of the worm-wheel. The bridge is raised again, when the table has turned through half a revolution, by cams c' on the wheel engaging with rollers carried by the bridge. While the table is in motion,.a valve in the air main E<4> and valves f controlling the delivery of sand from the container F to the sand pipe E<2> are closed by the action of cams g on a semicircular bar G, which is moved round against the action of springs by an arm G<1> secured to the shaft and acting through a trip lever. The spent sand passes back over an inclined plate e<4> to the container F, in which is located an air exhaust chamber in communication with the pipes h<1>. The work-holders are fitted with spring-controlled slide valves which cover the openings in the table and are retracted by the action of inserting the work in the holders. The work-holder may be set at an angle and may have oscillatory or other movement imparted to them.
