Patent GB-162516-A (GB)
Abstract: 162,516. O'Dell, A. E., (Aktiebolaget Original-Odhner). April 6, 1920. Multiplying and dividing apparatus.-Relates to improvements in the restoring-mechanism for the setting-elements of cam-disc, and pin-wheel machines, and is an improvement on the restoring-mechanism shown in Sepecification 128,062. On the setting-shaft 4 is pivotally mounted a plate 7 extending the length of the machine and terminating in one end in a grip 6. Attached to this plate by pins and slots is a plate-cam 8 laterally shiftable on the angular movement of the grip 6 by a recess 15 and projection 18 on fixed brackets on the machine, associating with projections 14, 17 on the cam. The bottom edge of the cam 8 is flanged inwards and contains slots which allow the passage of grips 2 and teeth 12 with which each dial is fitted, when the operating-shaft 4 is turned and the grip 6 is in its rest position. On the grip 6 being moved clockwise, Fig. 3, the plate-cam 8 is displaced to the right, Fig. 4, thus throwing the slots out of alignment with the teeth 12, which are carried round to put the setting-discs to zero. On releasing the grip 6, a spring 19 returns the restoring-lever to its rest position, and the projection 18 returns the cam 8 to the left. A modification is described in which the cam 8 is replaced by a spring-pressed pivoted plate.

Filed: 1966-04-14
Abstract: 1,190,264. Breathing alarms. E. B. COHEN. 13 April, 1967 [14 April, 1966], No. 16349/66. Heading A5R. A device for giving an alarm when breathing is abnormal or absent comprises a switching circuit, a timing circuit and an alarm circuit, the switching circuit including spaced electrodes D which, when the electrodes are bridged by moisture condensed from breath, is energised to charge a condenser 8 and render the alarm circuit inoperative and which, when no moisture is present, is de-enerigised and renders the alarm circuit operative after a time interval during which the condenser discharges. The circuits are arranged between negative and positive leads A, B energised by a battery C. The switching circuit includes two transistors 1, 2 comprising a Darlington pair, the second transistor 2 of which is connected to a light bulb 6 and through a diode 7, with the condenser 8. When the switching circuit is operated by condensed moisture bridging the electrodes D the Darlington pair 1, 2 conducts to energise the light bulb 6 and charge the condenser 8. Also, the base 'of a third transistor 3 becomes negatively charged and conducts to cause the base of a transistor 4 of a second Darlington pair 4, 5 to become positively charged and thus interrupt current to an audible alarm 11 and an indicator bulb 10. When the switching circuit is opened by evaporation of moisture on the electrodes D the second Darlington pair 4, 5 is initially maintained inoperative due to discharge of the condenser 8. Normally, the next exhalation of the patient causes closure of the switching circuit before the condenser discharge is complete. In the event that exhalation is weak or absent, the switching circuit remains open and as long as the condenser is discharged the base of the first transistor 4 of the second Darlington pair is negatively charged from the lead A to render the alarm circuit operative.

Title: Motion picture camera
IPC: G03B1/12
Filed: 1958-05-21
Abstract: 847,882. Kinematograph cameras. KOLB, O. K. (Bell & Howell Co.). May 21, 1958, No. 16352/58, Class 97(1) [Also in Group XXVI] In a spring driven camera means are provided for causing the film exposing mechanism to come to rest in the closed position when the spring has unwound to a predetermined extent. In the form shown the camera mechanism is driven through a ratchet from a hub 55 to which is anchored one end of a spring strip 56, the other end being secured by a screw 70 to a hub 63. The spring is least stressed when on the hub 63, the mechanism being wound by rotating the hub 55 by an external handle in the direction of the arrow 66. This movement is stopped when the screw 70 is uncovered and buts against a spring loaded pivoted stop lever 71. As the camera runs the strip returns to the hub 63. Meanwhile the nose 53 of a spring loaded lever 52 bears on the convolutions on the hub 55. The unwinding from the hub 55 ultimately uncovers a recess 54 in the hub and the nose 53 drops into it. This moves a detent member 48 at the other end of the lever into engagement with one of two stop shoulders 46, 47 formed on a cam 45 so located on a shaft forming part of the drive to the camera shutter that the shutter is closed when the mechanism is stopped. The shutter carries a crank pin actuating a reciprocating shuttle carrying a feed claw. The movement of the lever 52 as the spring unwinds is transmitted through a toothed sector 83 to another sector 84 carrying an index mark visible through a window to indicate how far the spring is unwound. A spring loaded lever on a shaft 92 bears on the film coil on the feed spool and is coupled through a sector 94 and pinion 95 to a disc 96 carrying film footage graduations visible through a window.

Title: Improvements in effort measuring devices
IPC: G01L3/14
Filed: 1945-06-27
Abstract: 605,194. Dynamometers. OLAER PATENT CO., and COMPAGNIE GENERALE POUR L'EQUIPEMENT AERONAUTIQUE. July 27,1945, No. 16449. Convention date, Sept. 8, 1943. [Class 106 (ii)] An effort-measuring device comprises at least one piston and cylinder transforming the efforts to be measured into liquid pressure, characterised in that said cylinder receives, from a pump or other source of liquid under pressure, an addition of liquid intended to compensate for leakage and in that said piston and cylinder arrangement is devised in such manner as to provide a leakage which increases proportionally to the increase of the volume of liquid present in the apparatus. In Fig. 1 is shown the known type of torque-measuring device to which the invention is applied. The shaft of which the torque is to be measured carries a pinion 1 which gears with three planetwheels 2, 3 and 4 carried by a frame 5 rigid with the part to which the torque is being transmitted and gearing with an annular gearwheel 6 which is connected by the rods 7 to the pistons 8 which thus move in the pistons 9 in accordance with the movement of the wheel 6, i.e. in accordance with the torque transmitted. A pressure gauge 12 is in communication with the two cylinders 9 and so gives an indication of this torque, but due to leakage in the cylinders or friction between the pistons and cylinders the true value of the torque is not indicated. In the present invention, Fig. 2, at least one of the cylinders 9 has a triangular orifice, as shown, so that the leakage increases proportionally to the amount of liquid in the system which is being supplied with liquid at a constant rate by a pump 13. In this way the rate of leakage automatically adjusts itself to the rate of feed and the amount of liquid present in the hydraulic system and the reading on the pressure gauge is therefore a true indication of the torque. In another embodiment, not shown, the controlled leakage is obtained by providing one of the cylinders 9 with a frustoconical flaring portion instead of an orifice. If desired, a pressure accumulator may be used instead of a pump.

Filed: 1928-06-07
Abstract: 291,798. Ges f³r Oberbauforschung, (Assignees of Hering, E.). June 10, 1927, [Convention date]. Skid; arresting grips or friction apparatus on permanent way. - A brake device for railway vehicles comprises an electromagnetic shoe movably arranged on the track for engagement with the passing vehicle. As shown in Fig. 1, the .electromagnetic shoe 1 arranged on the track and adapted to be magnetically attracted to the side of the wheel is provided with a nose 2 for engagement with the wheel 3. The current is supplied either through rails or the tail rope. According to Fig. 3, an electromagnetic shoe 1 arranged to slide along a fixed rail 4 is provided with a pair of hinged arms 6 which can be swung into the position shown to extend over the wheel rails by the outward movement of a spring 7 under the action of a magnet. The arms 6 can then be engaged by the vehicle wheels and the shoe 1 carried along thereby to give the braking action. The spring 7 serves also to absorb the shock of the impact of the wheels with the arms 6. Further to reduce the shock of engagement the first section of the rail 4 is not made of iron so that the magnetic braking action is delayed. When the current is switched off the spring 7 moves inwards, the arms 6 come together and the brake shoe thus comes to rest. A buffer may be disposed at the end of the rail 4 adapted to move back the spring 7 and permit the arms 6 to come together in case this has not already been effected by cutting off the current. After the current has been switched off, the brake shoe is automatically returned. The engagement of the brake shoe may be helped by an accelerating device which may comprise a spring or a, lever system controlled by the approaching wheel. This may be effected either by providing the shoe with an auxiliary motor acting on running wheels and switched in when the current to the braking magnet is switched off or by a rope attached to the shoe and adapted to be wound upon a motordriven drum. To reduce the impact between the shoe and the vehicle, the movement of the shoe may be initiated by a spring released by the wagon.

Title: Improved pulpstone and method of making the same
Inventor: COOK ARNOLD MARTIN
IPC: B24D5/08
Filed: 1965-04-21
Abstract: 1,030,592. Pulpstones. NORTON CO. April 21, 1965, No. 16690/65. Heading B3D. A pulpstone comprises a core having a circular cross-section and a plurality of segmental blocks secured by prestressed bolts about and in contact with the peripheral surface of the core, the blocks collectively forming an abrasive facing around the core, means being provided whereby the core is constantly constrained in compression circumferentially and means being provided on the prestressed bolts which secure the segments to the core and which also resist the centrifugal force developed in the segmental blocks while permitting constant circumferential compression on the core to be maintained. Abrasive segments 10 are assembled in a cylinder with temporary joint-forming material 52, e.g. a thermoplastic, between the segments. Each segment has secured thereto four bolts 16, the head of each bolt having a coarse thread or annular ribs anchored in a radial hole in the segment. Metal reinforcing hoops 30 are arranged in pairs on both sides of the bolts 16 within the cylinder. A retainer plate 36 is mounted on each bolt 16 so as to bear against the inner surfaces of the adjacent hoops 30 and a sleeve 34 is mounted on each bolt 16 with its outer end bearing against the plate 36. The hole in the plate 36 and the bore of the sleeve 34 are both of larger diameter than the bolt 16 to minimize heat transfer from the bolt 16 to the core. A nut 28 is threaded on the inner end of the bolt 16 with spring washers 26, 26 interposed between it and the inner end of the sleeve 34. The nuts 28 are tightened to impart a tension of approximately 2500 lbs. to each of the bolts 16 which is transmitted, through the sleeves 34 and retainer plates 36, to the hoops 30 so as to tension them. The outer surfaces of the bolts 16, nuts 28, washers 26, sleeves 34 and retainer plates 36 are coated with latex or the like, to permit movement of those parts relative to the core. A reinforcement for resisting destructive compression under the working load is arranged centrally of the cylinder. It comprises hoops 38, 40, rods 42, 44 and stirrups each having a base 48 and legs 50, 50 extending almost to the hoops 30. The hoops, rods and stirrups are secured together where they meet. Concrete or the like is poured into the space between the cylinder and a form for the central aperture 14 to form a core 12, and cured under trolled moisture conditions to minimize shrinkage. When the stone is put into use it heats up, so that the material 52 gives way. The bolts 16 hold the segments 10 against the core, and the tension in the hoops 30 is relieved to exert compression on the core.
