Abstract: 1,111,217. Rolling threads. ERNST GROB WERKZEUG-UND MASCHINENFABRIK. 7 Feb., 1966 [9 Feb., 1965], No. 5254/66. Heading B3M. A thread is rolled on a workpiece W by means of two rolls 1 and 2 which initially rotate at the same speed, one of the rolls then being rotated slightly faster than the other in order to draw the workpiece through the narrowest gap between the rolls, and the difference in speeds then being removed. One roll is axially movable against spring pressure to permit its profile to mate with that formed on the workpiece by the other roll during speed changes in the rolls. The rolls are rotated by means of toothed worms 5 and 6, the worm 6 being axially movable by means of a lever 13 to vary the speed of rotation of the roll 2 relative to that of roll 1. The lever 13, and also a workpiece feeding bar 3<SP>1</SP>, are driven in synchronism by cranks 12 and 10 from a common rotating wheel 7a. The feeding movements performed by the bar and the roll 2 can readily be adjusted by altering the position or lengths of the cranks. The mechanism for varying the speed of roll 2 may embody epicyclic gearing or synchronously driven cams.

Title: Suspension system for motor vehicles
IPC: B60G17/019
Filed: 1958-02-18
Abstract: 852,845. Road vehicle spring suspensions. BENDIX CORPORATION, [formerly BENDIX AVIATION CORPORATION.] Feb. 18, 1958 [Feb. 27, 1957; March 18, 1957; May 22, 1957], No. 5271/58. Classes 108(2) and 108(3). A car suspension system comprises fluid suspension units connected between the wheels and the chassis, valves which automatically - vary the pressures in the units in accordance with changes in the loading of the car and the conditions of the road, means which delay the changes in pressure in the units for a predetermined period of time after each actuation of the associated valve and means responsive to changes of inertia of the car, which a pair of springs 90 is delayed by one of a pair of dashpots 92 which are set to give the system time to fully correct the inclination of the car. The levelling valves 48, 50 control the front wheels and are operated by a single weight 86, whilst the rear wheels are controlled by a single weight operated valve 44. In a modification (Fig. 5) movement of a weight 282 rotates a shaft 284 having a, threaded connection 290 with the valve structure, thereby moving pistons 264, 266 against the action of springs 272, 274 to increase the rate of flow of fluid through conduit 302 between chambers 300 and 304. The pistons each have a ball valve 280 and a small bore 276 which enable valves 254, 256 to be actuated instantaneously when weight 282 has been displaced from its central position and for a time after the weight has returned to its central position; which time is determined by the time taken for the displaced pistons to return to the position shown. In another modification (Fig. 6) ball valves 454, 456 are actuated directly by spring lever 448 and a lever 450, and a restriction is introduced in the flow of liquid to each unit 414 by a valve 412, constructed similarly to the valve shown in Fig. 5. eliminate the delay when the car is accelerating, braking or cornering. The units 18 (Fig. 2) each comprise a hydraulic reservoir 20 which contains a bladder 22 and communicates through a damping valve 30 with a space 28 above a piston 26 which is connected by a rod 32 to the associated front or rear axle. The spaces 28 in cylinders 24 are connected to levelling valves 44, 48, 50, which admit fluid to the spaces 28 from a hydraulic accumulator 40 in accordance with movement of the associated wheel. To prevent hunting developing in the system the movements of the wheels are communicated to the valves by spring levers 68 (Fig. 3) which actuate inlet and outlet ball valves 72, 74 in each levelling valve through a piston 70, movement of which is normally damped by the restricted passage of fluid through a conduit 80. When however, due to violent cornering or change of velocity, weight 86 is moved from its central position, a passage through valve core 82 allows free flow of fluid through conduit 80 thereby producing rapid operation of the ball valves 72, 74 to correct the level of the car. When the forces acting on weight 86 are removed its return to the central position under the action of one of

Abstract: 688,951. Apparatus for examining photographic negatives. SCHONANDER AKTIEBOLAG, G. March 5, 1951 [March 9, 1950], No. 5309/51. Class 98 (ii). [Also in Group XVIII] A frame rack in or for an inspection device for X-ray films comprises several frames 16, each for mounting several films and each movable along the rack to a position in front of the window of an inspection case placed to one side of the rack, and a carriage 6 having several longitudinally-extending parallel tracks 12, 14 on which the frames 16 may run, said carriage being displaceable in a direction normal to the direction of movement of the frames 16 to alter the positions of the frames relatively to the base 4 of the rack. As shown, each frame 16 comprises frame members 18 mounting glass plates 22 across which the films, clipped at 30 to a member 18 and to a cross-piece 20, are held by wires. The upper and lower frame members 18 are provided with trundles 26, 24 which run on the tracks 14, 12 in the carriage 6 which is movable stepwise in a direction normal to the rails when a catch engaged in a recess in a bar 41 on the base 4 is released therefrom by operation of a lever 38 connected to the catch by a cable 40. Such movement of the carriage brings one of the tracks 12, 14 into alignment with a rail extending from an inspection case so that the frame mounted on said track can be moved into position in front of the inspection window of the case. A hinged member 44 and a bar 42 are provided to prevent longitudinal movement of the frames, other than that which is mounted on the track 12, 14 aligned with the rail extending from the inspection case. A scale 48 on the bar 42 and an index 46 on the carriage indicate which frame 16 can be moved longitudinally.

Title: Improvements in or relating to apparatus for reading records and in communication systems
IPC: G01M3/32
Filed: 1940-03-23
Abstract: 539,810. Electric communication systems and statistical machines. BRITISH TABULATING MACHINE CO., Ltd. March 23, 1940, No. 5378. Convention date, March 25, 1939. [Class 40 (iii)] [Also in Group XIX] Relates to communication systems and statistical machines in which signals are produced by the scanning of a record having index points arranged in columns for different significances and in rows for similar significances and in which the record is fed mechanically to present the successive rows successively to the scanning position in known manner. According to the invention the index points in a row are scanned by a series of successive impulses generated by a linear scanning action of a cathode-ray. Reference is made to Specification 538,603 for a similar scanning system in which the impulses are produced from alternating currents having phase differences. The cathode-ray may be made to close successive circuits directly or, as shown in Figs. 1 and 7 the cathode-ray of a cathode-ray tube Tl produces a travelling light spot on a screen S opposite a lens system U and a line of light responsive devices L and the record is brought by the usual feed mechanism shown in Fig. 1 across the beam of light, so that impulses are produced by the light sensitive devices distributive and timed in accordance with the index points marked in the row being scanned. These successive impulses can therefore be sent over a single transmission channel to a synchronized receiving apparatus. As shown, the signals modulate a carrier supplied to a transmitter 100, Fig. 7, and received by a receiver 101, Fig. 7A, leading up to a cathode-ray tube T2 synchronized with the cathode-ray tube T1 and serving to distribute the several signals-belonging to the several columns of the record. In addition to this cathode-ray scanning, the next record before it reaches the cathoderay tube T1 is scanned by contact brushes UB, Fig. 1, in known manner and the two scannings compared for " automatic group control." For this purpose, the signals produced by the light sensitive devices L subjected to the action of the cathode-ray tube T1 are made to operate another synchronized cathode-ray tube T3 to distribute the signals to targets t adapted to be connected in circuits in series with other circuits controlled in known manner by the brush scanning device. The Specification describes in addition printing mechanism, counters and other devices of usual kind adapted to the present scanning system. Two light sensitive devices L<SP>1</SP>, L<SP>11</SP>, Fig. 7, are provided for use in connection with a total printing and reset cycle.

Title: Improvements in distance or range finders
IPC: G01C3/12
Filed: 1943-04-05
Abstract: 564,754. Range-finders. EDEN, J. L. April 5, 1943, No. 5392. [Class 97 (i)] A short home-base range - finder gives two overlapping images of different magnification obtained from two spaced view - points. Since the images are of different sizes, they can coincide at one point only in the field of view, a double image being seen elsewhere. Owing to the relative shift between the two images produced by the parallax effect, the position in the field of view of the poiht at which the two images coincide corresponds to the distance of the object plane, so that observation of this point enables the range of the object to be determined. In the form shown, the images are formed by two spaced lenses 3, 6 of different powers and are viewed through a pinhole 12, that from the lens 3 being seen by reflection from a prism 2 and neutral-tinted glass plate 5, and that from the lens 6 by transmission through the plate 5 and also through a second glass plate 7. An image of a scale 8 is also seen in the field of view by reflection from the plate 7, a negative lens 10 being interposed between the plate and scale. The use of a pinhole eyepiece allows the two images and also the scale to be seen simultaneously in focus. The system is so arranged that the two images of a point or line on a distant object coincide when the instrument is directed so that they appear at one end of the scale image. For nearer object planes the two images will, owing to the parallax effect, undergo a relative shift to an extent dependent upon the nearness of the .object plane, so that, due to the different sizes of the images, the coincidence point will travel across the image field, and its position may be observed in relation to the image of the scale 8. This scale may be an ordinary millimetre scale, a comparative scale on the case of the instrument giving the ranges corresponding to the readings obtained on it. A second viewing pinhole 4 is provided in the end of casing, farther than the pinhole 12 from the corner to which the plane of the glass plate 5 is directed, so that the two images seen through the pinhole 4 are shifted relatively to one another as compared with those seen through the pinhole 12. This allows long and short range readings to be obtained by use of the pinholes 12, 4 respectively. In a modification, the lenses 3, 6 are of the same focal length, the observed images being of different sizes owing to the difference in the optical paths from them to the pinhole. The lens, 3 is arranged between the prism 2 and glass plate 5, and the plate 7 and lens 10 are not provided. The scale 8 is arranged between the lens 3 and prism 2 and may be inclined to the plane of the lens so that the graduations are increasingly magnified towards the end giving the maximum range readings. Alternatively, a mirror may replace the prism 2 and the scale may be engraved on it.

Filed: 1918-03-30
Abstract: 127,359. Cockburn, D., and MacNicoll, D. March 30, 1918. Stop - gear. - Emergency cut-off apparatus for turbines &c. comprises a valve 7 which, when opened by a centrifugal device acting on a lever 2, 4, permits pressure fluid to pass to the valve 10 of a relay device controlling emergency valve-gear. When the lever is moved by the centrifugal device, such as the bolt described in Specification 127,360, a spring pin engages a slot 3 and locks it, while allowing a certain amount of play. In order to move the lever out of contact with the centrifugal device, a piston 11 is slidably mounted on the valve spindle and is open to the atmosphere on the underside and to the pressure fluid on the upper side, so that when the valve 7 is opened the pressure fluid forces the piston down and holds the valve open.
