Title: Improvements in screw and nut mechanism
Inventor: BRADFIELD ALAN HERBERT EDWARD
IPC: F16H25/22
Filed: 1957-07-17
Abstract: 891,025. Screw-and-nut gearing. CAM GEARS Ltd. July 11, 1958 [July 17, 1957], No. 22630/57. Class 80 (3). In a screw-and-nut mechanism, particularly for a vehicle steering gear, the screw 1 engages the nut 2 through a series of balls 3 circulating in a component 5 of strip metal which comprises a closed loop shaped to provide both the nut part 6 and the return passage 7 for the balls. The component 5 may be formed to provide any desired number of helical turns, but usually provides, as shown, about half a turn. The passage 7 comprises a reverse helix which may, as shown, be closed towards the interior of the loop so as to carry the balls clear of the screw threads, or may be open towards the interior so that the balls roll over the screw crest. The component 5 may be formed from a single strip of steel or, as shown, may be formed in two spaced halves intermittently welded together. Alternatively, the two halves may abut or be continuously welded.

Title: Improvements in or relating to punching or shearing machines
IPC: B21D22/00
Filed: 1969-05-05
Abstract: 1,273,238. Punching; shearing. P. C. PEDDINGHAUS, and W. PEDDINGHAUS, [trading as PAUL FERD. PEDDINGHAUS]. 5 May, 1969 [8 May, 1968], No. 22729/69. Heading B3W. A shearing apparatus, particularly a punch press, comprises a tool slide 4 releasably coupled to a driving ram 7 by engagement of a nose 17, on a pawl 16 pivoted to the ram, with an abutment 14 on the slide. A pin 18 on the pawl is slidably engaged in a slot 19 in a cranked lever 20 pivoted to the slide at 23 and urged by spring 21a into the position shown. A fixed fluid jack 25 has its piston 24 resting on the arm 22 of the lever. To uncouple the punch slide 4 from the ram to enable the punch St to be moved almost into contact with a workpiece G for alignment purposes, the piston 24 is extended which first pivots the cranked lever 20 about pivot 23 until it abuts a stop 20<SP>1</SP> on the slide, this movement causing the pawl nose 17 to be disengaged from the abutment 14. Further extension of the piston 24 moves the slide downwards against the action of springs 11 anchored at their upper ends 11a to the press frame. The piston 24 is actuated via a cylinder 26 by moving a lever 29 in the direction K. With the punch in position adjacent the stock, pressure on a pin 30 in the direction S actuates the ram 7, a rounded portion 6 of which engages in a complementary recess 5 in the slide 4 and forces the punch St through the stock. The lever 20 having been moved away from the stop 20<SP>1</SP> by the spring 21a, the pawl nose 17 re-engages under the abutment 14 on the slide and carries the slide and punch up with it to the position shown. The punch may be replaced by a shear blade, particularly one for notching.

Title: Improvements in or relating to tunable electric oscillators employing frequency stabilisation
Inventor: MILLS RONALD ALFRED
IPC: H03L7/20
Filed: 1959-07-06
Abstract: 913,364. Automatic frequency-control systems. GENERAL ELECTRIC CO. Ltd. July 6, 1960 [July 6, 1959], No. 23126/59. Class 40 (5). An oscillator 1 continuously tunable, e.g. over 3-20 mc/s., is stabilized relative to harmonics of a 100 kc/s. crystal oscillator 4 and an interpolation frequency set by a tunable A.F.C. frequency discriminator 7 ganged with the tuning of the oscillator 1. Crystal harmonics, generated at 3, pass through a filter 5 (cutting-off any harmonics of higher frequency than oscillator 1) and beat with the oscillator 1 in a mixer 2 before passing to a filter 6 of pass-band just over 100 kc/s. and A.F.C. discriminator 7. The latter comprises two frequency discriminators 8, 9 in parallel, one 8 being tunable by a capacitor over a range 150 kc/s. centred on the mean frequency of the pass-band of filter 6 during three-quarters of its rotation but during a final quarter rotation of the capacitor (returning it to its initial value), the discriminator output being reduced to zero by a switch; another 9 having a tuning capacitor and frequency sweep over the same frequency range as but 180 degrees out of phase with the capacitor variation of discriminator 8 and its output likewise rendered zero by a switch during a final quarter rotation. If one only of the 100 kc/s. harmonies is passed by filter 6 (therefore lying around its centre frequency), only discriminator 8 is operative, but if two harmonics pass (at the ends of the pass range of filter 6), both of discriminators 8, 9 pass outputs, being then tuned apart by 100 kc/s. Preferably the discriminator conjoint outputs are equal to what would be obtained if one signal only was passed by filter 6.

Title: Improvements in indexing mechanism
IPC: B23F23/08
Filed: 1949-09-07
Abstract: 672,273. Machine-tool details. CLAMEDELL, Ltd., (trading as SOUTHERN ENGINEERING & MACHINERY CO.), and CLARKSON, W. R. Sept. 7, 1950 [Sept. 7, 1949], No. 23167/49. Class 83 (iii). Indexing mechanism for rotating a shaft through a predetermined angle, particularly applicable to the indexing head of the gear cutting &c. machines described in Specification 672,274, [Group XXIV], comprise means adapted to apply torque to said shaft 10, Fig. 1, tending to turn it in a given direction, stop means 16, 17 engaging said shaft to prevent rotation in said direction only, means for reversing the direction of torque when an indexing movement is initiated and for restoring the original torque after the shaft has been rotated through, at least, the predetermined angle, this torque being maintained when the shaft is arrested. The shaft 10 is connected to the member carrying the workpiece through reduction gearing which may include change gears and is rotated for indexing from a worm shaft 13, Fig. 3, by means of a fluid motor. A spiral cam 16 is keyed to the shaft 10 adjacent the worm wheel 12 for driving it. A spring-pressed lever 18 has a roller 17 at its free end which engages the periphery of the cam and acts as a stop against a step in the cam to resist the torque maintained by the fluid motor. When a carriage supporting the work is moved to its initial position, a switch (not shown), is operated to reverse the direction of motion of the fluid motor for the indexing movement of the shaft 10; this continues until the roller 17 rides up to the top part of the cam, whereupon a switch 23 is moved by the plunger 19 to reverse the motor. The roller 17 moves over the step in the cam and then acts on a stop against the reverse action of the motor which is maintained during the working operation. Two steps may be provided on the cam disc 16 and where the disc and shaft is required to index a number of times before being stopped at the steps, further reduction gearing 24, 25, Fig. 3, is arranged on the end of shaft 10 which rotates a disc 27 having a flat or flats allowing a switch 28 to operate. This switch while in the raised position nullifies the effect of switch 22 but, when allowed to fall by the flats on disc 27, switch 22 becomes'operative to reverse rotation of the motor and stop shaft 10 in the required position.

Abstract: 1437971 Calculator for a child's drug dosage D BARLTROP 18 March 1974 [16 May 1973] 23231/73 Heading G4B Given a child's weight and height its drug dosage for a given condition can be related to the corresponding adult ease by the formula: percentage dose equals the product of: (a) weight, raised to a first predetermined power, (b) height, raised to a second predetermined power, and (c) a constant, or several constants; the result is based on a formula for bodily surface area. A device for making the calculation comprises relatively movable discs 10, 11, 12, carrying various logarithmic scales, and a transparent cursor 18, mounted co-axially by a pivot 13; the cursor has three hair-lines 19-21. Aligning 19 with the value of weight on the log-log scale 16 causes 20 to correspond, on the same scale, to the value of weight raised to the first predetermined power; aligning 19 with the value of height causes 21 to correspond to height raised to the second predetermined power. The logarithmic scales 14, 15, 17 are used to form the product of these two numbers together with the predetermined constant or constants, to give the percentage dose.

Abstract: 480,705. Warp stop-motions. WAGNER, C., (trading as WAGNER, E. T., [Firm of]). Aug. 26, 1936, No. 23465. [Class 142 (i)] In mechanism wherein upon warp breakage a fallen heald or dropper checks the relative longitudinal movement of racks 13, 15, these have oppositely directed teeth and one or both are rotatable through 180‹ about a longitudinal axis to make their teeth inoperative as shown in Fig. 7, both then presenting smooth unserrated surfaces to the heald heads &c., whereby assemblage &c. of these is facilitated. The outer rack 13 may be partly tubular and be provided with end projections 14 engaged by recesses in resilient supports 11 and be thereby held in the position shown or after rotation, whilst the inner rack 15 may have flat recesses 16 engageable in its two positions by the prismatic end of a spring-loaded pin 18 carried by a stirrup 17. The supports 11 are secured to the detector frame 10 and carry a smooth wire 12. The stirrup 17 has a spring- loaded pin 20 which is guided longitudinally in the frame 10 and normally causes the stirrup to contact with the side support 23. When the frame is in its lower shed position, a pin 31 on a bell-crank lever 29 oscillated by lever mechanism from a cam &c. on the tappet shaft moves the stirrup and rack to the right, the spring-loaded pin normally moving the rack to the left when the frame rises. If this movement is prevented by a fallen heald, the stirrup remains in position to engage a plate 33 and rock a lever 34 connected by a Bowden wire device &c. to a member 38 and bolt 39 on the stop spring 49. The bolt 39 is thereby withdrawn from a looking ring 41 and this is rocked on its pivot pin by a weighted disengaging bolt 45, which moves into the path of a long abutment plate. The bolt 45 and stop spring 49 are thereby operated to stop the loom. The rack 13 may be oval in section. The invention may be applied to dropper wire stop motions. The rack movement may be effected from the heald frame movement. The manner in which the racks are manipulated when assembling healds &c. is described.
