Title: Improvements in or relating to Integrating Devices.
Inventor: RICKETTS LUTHER WELLS
IPC: G06F17/40
Filed: 1967-01-24
Abstract: 1,170,114. Integration devices. MAGNAVOX CO. 24 Jan., 1967, No. 3459/67. Heading G4A. A digital integrating device, comprises a memory having a plurality of different addresses therein storing integrals of input signals from different sources, arithmetic means coupled to the memory, memory addressing means, selectively adjustable timing means establishing a sequence of processing periods and coupled to the addressing means and to the memory to cause read out of an integral from a memory address and writing of an integral into said address during a processing period established by the timing means, said addressing means processing different addresses for different processing periods, and input sampling means coupled to the arithmetic means to employ input signals sampled during a processing period to change the integral read out of a memory address during said period before writing back into said address. As described, analogue input signals from 950 sources are converted into digital form and sequentially sampled by means 66 in synchronism with the stepping of a cyclically operating address counter 32 associated with a magnetic core memory 31, the multiplexed sample signals on a line 57 (two bits per sample) being fed to an input counter 54 associated with input weighting switches 58 which may be manually set to vary the significance of the input signals. In synchronism with the registering of each sample, the corresponding old integral word (11 bits) from memory 31 is read into a sense register 43 and shifted therefrom through serial subtractor and adder units 46 and 47 (where it is updated by the new input data) to a write register 48 from where the new integral word is written into the memory 31 in the place of the old word. A control counter 37 controls the sequencing of operations for each sample. The write register 48 may be connected through digital to analogue and threshold circuits 61 for example to a pen recorder. Overload indicator lamps may similarly be connected. Depending on the setting of a mode selection switch the device may provide RC or linear integrations according to the following equations respectively: where In and I o  are the new and old values of the Integrals respectively, the values of X 0 , X 1  and X 2  are determined by the count in input counter 54, k represents the weighting factor which may be selected manually from the integers 0, 1 . . . A-1 where A is the number of memory bits per work and n is an integer which determines the particular integration curve and may be selected manually from the values 1, 2 . . . A-1 and infinity. A detailed embodiment is described with reference to Figs. 4-15 (not shown). In modifications, the arithmetic operations may be performed in parallel and the values n and k and the mode of integration may be selected by programme.

Title: Improvements relating to article-diverting apparatus
Inventor: MORTON STANLEY FREDERICK
IPC: B65G13/00
Filed: 1966-10-24
Abstract: 1,200,725. Roller conveyers. SOVEX Ltd. 24 Oct., 1967 [24 Oct., 1966; 27 jan., 1967], Nos. 47655/66 and 4098/67. Heading B8A. Apparatus for diverting conveyed articles auch as bundles of newspapers includes crowned rollers 5 which may be covered with rubber and whose mountings 9 are rotatable in vertical bores 11 provided in fixed members 12. For rotating the mountings 9 in unison, arms 17 are reciprocable by a crank and crosshead device 18-22. Alternatively a chain in engagement with the mountings 9 may be used. The drive for the crank-shaft 22 is through a clutch 49, a brake unit 51 and a chain 46, a limit switch or switches being operable by the shaft 22. Each roller 5 is drivable by bevel gears 28, 29 and by a sprocket 31, these sprockets being driven by a common chain 44. The rollers can be driven in one or other direction depending on which one of two clutch units 42 (one only shown) is engaged. A motor 33, through a gear-box 34 drives the shaft 22 and the sprockets 31. Assuming that a bundle is to be transferred from the top side to the right hand side relative to Fig. 1, that clutch 42 is engaged which will cause the rollers 5 to advance the bundle from top to bottom. When the bundle is symmetrically positioned on the rollers, the clutch 42 is disengaged and clutch 49 is engaged, causing the rollers to turn through 90 degrees about the vertical axes of the mountings 9. The clutch 49 is then disengaged and the clutch 42 engaged to cause the rollers to move the bundle off to the right. After again disengaging the clutch 42, the roller mountings are returned to their initial positions. The above sequence may be automatically or manually controlled. For changing the orientation of an article while on the apparatus the rollers 9 are brought to a tangential position in relation to circles about the centre of the apparatus. In Fig. 9 the mountings for the rollers are rotatable by a chain 54, a sprocket 55 and an arm 56 which arm takes the place of the crank arm 21 on the shaft 22. The rollers 5a, 5b are rotated in a reverse direction compared with rollers 5c, 5d. Separately reversible drives for the rollers are necessary, these being provided, for example, by electromagnetic clutches or a friction drive as in Fig. 11 (not shown). Articles are fed to the rollers 5 by sets of rollers 3 which may be driven or undriven.

Title: Improvements in brake blocks or linings with a view to increasing their adherence
IPC: F16D69/00
Filed: 1937-02-11
Abstract: 488,382. Friction surfaces for brakes. SMALZI, P., and TOSONI, D. T. Feb. 11, 1937, No. 4109. Convention date, Feb. 11, 1936. [Class 103 (i)] Brake blocks or linings for cycles, automobiles &c. have the friction surface divided into elements by a relatively large number of grooves so that each element is so small as to be deformed under the braking pressure, some or all of the grooves extending transversely completely across the block or lining and being perpendicular to the surface while the width of a groove is substantially less than the distance between them. Figs. 1, 4 show blocks with two arrangements of grooves. The grooves may instead be of zigzag form. The material may be a compound with a base of rubber or fibre. Channels may be formed in the bottom of the grooves, Fig. 1, to drain away mud and water. The elasticity of the block may be increased by the provision of interior passages as in Fig. 4. According to the Specification as open to inspection under Sect. 91, the friction surface may have cup-shaped recesses instead of grooves. Further, in the case of large surfaces, the grooves or recesses may be filled with a malleable metal such as aluminium or brass, the metal being level with the surface. This subject-matter does not appear in the Specification as accepted.

Patent GB-197718-A (GB)
Title: Improvements in weft supplying mechanism for looms
IPC: D03D45/34
Filed: 1922-02-13
Abstract: 197,718. Smith, A., and Shackleton, G. W. Feb. 13, 1922. Shuttle-changing mechanism; shuttles.-In shuttlechanging mechanism of the rotary-box type, when the shuttle in action is almost depleted of weft a bunter catch 11, Fig. 1, is operated by the weft hammer and consequently a lever 13 and shaft 14 are rocked, and by means of a rod 16 a hook 5 is moved into the path of a cam-oscillated lever 6 whereby a lever 4 is rocked and a hook 3, Figs. 1 and 4, is operated to turn the rotary shuttle-box and bring a fresh shuttle into operation. Normally, however, the weft in the shuttle engages a feeler and rotates a shaft, so that an arm thereon moves the catch 11 out of the path of the weft hammer. After the shuttle-box 2 has been turned so as to bring in succession all the fresh shuttles it contains into action, a cam surface 8<b> on the edge of the peg-wheel 8 of the box comes into such a position as to engage a pin 3<a> on the hook 3, which is thereby prevented from engaging the pegs on the wheel 8 when it is next operated. At such time, moreover, a second pin 3b on the hook rides over the cam part 8b whereby the hook is moved into position to engage and operate a pin 17<a> on a lever 17b on a spring-controlled shaft 18 carried by the lay. A bunter finger 21 on the shaft is thus moved into position to engage, when the lay advances, a part 22<a> on an arm &c. 22 on a shaft 23, which is thereby rocked, and a lever thereon engages the loom " starting handle " and stops the loom. The weaver then operates a pedal 27a on a spring-controlled companion lever to the lever 4, whereby a hook 28 is operated and turns the shuttle-box in the opposite direction to enable him to replace the depleted shuttles by fresh ones. When the weft breaks, the loom is stopped by ordinary weftfork mechanism. If the free working of the outer end of the lever 6 is interfered with, the inner end rises against the action of a spring 33a and operates a rod 31 and lever 30, thereby turning the shaft 23 and stopping the loom. According to one Provisional Specification, the shuttles are provided with bobbins or spools with slots &c. in the walls into which the weft feeler can enter. Moreover, the stoppage of the loom is effected when all the shuttles in the rotary box have been used by the yielding of the box-operating mechanism. The weft-fork mechanism stops the takeup motion.
