Title: Improvements in or relating to control mechanisms for three dimensional variables
IPC: F16H35/16
Filed: 1964-08-24
Abstract: 1,082,296. Lathes. A. ADEGBOYE. Aug. 24, 1964, No. 34593/64. Heading B3T. [Also in Division F2] A control mechanism for controlling, e.g. the cutting speed of a lathe or variable-speed drive, in accordance with three variables the interrelation of which can be represented by functions of a conic surface or by conic sections such as a hyperbola or parabola, comprises an inclined guide 1 which can rock about an axis U, U on a slide 4 to trace a conical surface, and slidably carries a yoke 14 secured to a rod 15 slidable in fixed guides along its fixed horizontal axis Y, Y. The guide-slide 4 can be traversed on a vertical axis Z, Z by a leadscrew 8 and handle 7 along a column 5, which can itself be traversed by a push-rod 10 along a horizontal axis (X, X, Fig. 2, not shown), inclined to the axis (X, X) at twice the angle of inclination of the inclined guide 1 (i.e. at the cone angle). The three variables x, y, z are represented by linear movement respectively of the rods 10, 15 and slide 4 along the axes (XX), YY, ZZ, and are connected by the relation zy = kz<SP>2</SP> where k is a constant. To use the hyperbolic relation for obtaining constant cutting speed v at variable radius r during a facing operation on a lathe, the pushrod 10 is moved by the cross-slide tool movement so that r is represented by x; the guideslide 4 is adjustably fixed to the column 5 by the hand wheel 7 at a setting shown on a scale 17 as representing cutting speed v and fixing the z component; whilst movement y of the rod 15 along its fixed axis Y, Y by the combined x movement of the push-rod 10 and rocking of the inclined guide 1, controls a variable-speed drive to the lathe spindle to represent its rotational speed w. Thus, with z constant, xy, and hence rw, the cutting speed, are also constant. To use a parabolic relation, the push-rod 10 is fixed, making x constant, so that y and z are connected by the parabolic relation y = (constant) z<SP>2</SP>.

Title: Improvements in sewing machine lubrication systems
IPC: D05B71/00
Filed: 1955-12-05
Abstract: 775,069. Sewing-machines. UNION SPECIAL MACHINE CO. Dec. 5, 1955 [Dec. 9, 1954], No. 34701/55. Class 112. [Also in Group XXXIV] In a sewing machine having a moving part which requires to be fed with lubricant at a precise rate, liquid lubricant is fed to this part through a capillary delivery element, and means is provided for adjusting the effective length of the capillary delivery element to adjust the rate of feed of lubricant. The machine shown is of the general character described in Specification 676,955 and has a rotary hook 21 which co-operates with a needle in the formation of lockstitches. The hook is secured to the end of a shaft 22 the bore of which is adapted to receive lubricant from a reservoir 37 by the aid of porous elements. A porous wick element 38 extends through an opening 39 in the reservoir and is folded over the end of a spring member 40 which presses the folded portion against the periphery of a circular portion 45 of a porous member. The circular portion is not a complete circle and one end has an inwardly-extending portion 46 carrying a smaller portion 47 adapted to fit tightly on the end of the hook shaft 22. The porous member is secured to a metal support 48 within which a disc 52 is firmly secured. The disc is pressed up against the end of the hook shaft 22 by a spring-pressed plunger 54 slidable within an axial opening in an adjustable shaft 56. The shaft 56 has a radiallyextending flange 58 with a pin adapted to cooperate with a notch in the disc 52. The shaft 56 has a helically-toothed portion 61 engaging a worm 62 on a bolt 63 journalled in the reservoir. The bolt has a slot 64 to receive a screw driver for turning the bolt and thereby turning the shaft 56. Thus the point of contact of the wick element 38 with the portion 45 of the porous member can be adjusted and thereby the rate of travel of the lubricant along the porous member can be varied. The lubricant delivered to the central portion 47 of the porous member is picked up by the co-operating face of the disc 52 and is then pumped to the bore of the hook shaft 22 by a spiral groove formed in the end face of the shaft. The lubricant passes along the bore of the shaft 22 to the raceway of the hook 21. The bore is preferably flared its diameter increasing towards the hook end, and it preferably contains a wick element 74 bent upon itself, so that a small amount of lubricant is retained within the bore when the machine is at rest.

As shown, there are provided sets of six supports 38 for supporting the lower sheet of an assembly, three on each of the chains 22, each support 38 having a rubber top portion 40, and intermediate sets of four supports 42, two on each of the chains 22, each support 42 having a rubber top portion 44 which engages the edge portions of the sheet G and is inclined downwardly towards the centre of the sheet. A pair of stationary supports 50, each coated with a rubber sheet 51, is positioned at the loading end of the conveyer to facilitate the loading of the glass sheets on to the supports 38 or 42. In operation, upper and lower sheets of glass G are positioned on the supports 50 in alternate sequence are manually lowered on to the appropriate sets of supports 38 or 42. An operator then places a sheet of plastic material on the lower sheet as the latter travels along the conveyer, after which the upper sheet is lifted manually from the support 42 and placed on top of the plastic sheet which is positioned on the lower glass sheet, after which excess plastic material is trimmed away from the edges of the assembly. Cross-bars 32 are connected between two chains 22 and carry brushes 52 which travel over the surface of a table on which the trimmings of plastic material collect and sweep these trimmings away. A stationary brush 54 is provided on the conveyer framework to remove trimmings adhering to the lower runs of the chains 22.

Abstract: 1,152,401. Time-division and concentrator telephone system. WESTERN ELECTRIC CO. Inc. 4 Aug., 1966 [7 Aug., 1965], No. 34949/66. Heading H4K. In a time-division communication system including a concentrator terminating a plurality of subscribers lines a central office for establishing and controlling call connections and a time-division highway comprising send and receive paths for the respective directions, in which distinct channels in the two directions are reserved for the transmission of control signals between the central station and the concentrator, the concentrator includes a store for control information received, a command receiver for signals relating to the change of status of call connections, and a control circuit for comparing a command with related control information previously entered in the said store. The system is the same as that described in Specification 1,152,402 and a command comprises a 7-bit line number, a reduced call progress bit " 0 " or " 1 " for determining whether information is to be coded or whether the line is merely to be scanned, parity bits and separation bits before and after the time slot number, and a 3-bit order. A gating arrangement by means of which the condition of a scanned line is reflected to the scan circuit, or intelligence is passed to a delta modulator in accordance with the line condition indication in the concentrator memory is also described. The detection of errors in command signals is discussed, together with the selection of codes, the latter being selected so that errors will basically have no effect on continued proper performance. Synchronization of the time-slots is effected over an additional time-slot, and a number of synchronization codes together with time-slot durations and frame times are exemplified.
