Abstract: 1,025,328. Securing by threadless bolts. A. RAYMOND. Jan. 21, 1964 [Feb. 8, 1963], No. 2627/64. Heading F2H. [Also in Division E2] A fastener 10 has two arms 11 joined by a web in an approximate U shape, the free ends of the arms being bent outwardly to form outwardly directed feet 15, each arm being formed with transverse folds intermediate its length constituting an external shoulder 13 and an internal step 13a in the arm, and the arms being inclined inwardly towards each other from the shoulders to the feet and outwardly away from each other from the steps to the web. In a first embodiment, Fig. 1, the fastener is used to join together two flat apertured members 18, the arms 11 extending through the apertures and the members being clamped between the feet 15 and the shoulders 13. A pin 19 inserted between the arms 11 holds them in firm engagement with the rims of the apertures. Flanges 12 on the arms retain the pin, and the fastener is prevented from rotating by prongs 16 on the feet 15 which dig into one of the apertured members. The prongs 16 also hold the head of the pin above the member 18 to facilitate its removal by pliers. In further embodiments, e.g. Fig. 5, the feet 15 are flat and in the embodiment of Fig. 5, the flanges 12 are replaced by prongs 25. When the feet 15 are flat, the head of the pin may have undercut surfaces to facilitate its removal. The fastener can alternatively be used to secure a shaft formed integrally with the pin 19 to a panel, or to connect three apertured members. The fastener is made from metal strip. The arms 11 are alternatively arcuate in cross-section and there may be more than two of them.

Centrifugal speed indicators for use on motorvehicles, aeroplanes, &c. combined with pneumatic means for transmitting movements to distant indicators similar to that described in Specification 13796/13, [Class 106 (ii), Dynamometers, &c.]. The centrifugal device 6, driven through a pulley 3, is connected by links 8 to a collar 10 engaging a non-rotatable rod or shaft 11 slidable in a cross-support 12 and steadied by engagement of an extension 18 thereof with a hollow extension of the pulley shaft 1. The lower end of the rod 11 is secured to a flexible diaphragm 14. the edges of which are secured between the casing 13 and a dished cover 15, forming an air-tight chamber 17. By means of a nozzle 16, and flexible tube, the chamber 17 is connected to a distant indicating-device comprising a second chamber having a flexible diaphragm, the movements of which are transmitted to an indicating pointer carried by a spindle as described in the above-mentioned Specification. Endlong movements of the rod 11 under the centrifugal control distort the diaphragm 14, causing variations in the pressure within the chamber 17, such variations being transmitted through the tubular connexion to the second chamber and causing reciprocal movements of the second diaphragm, which are transmitted to the pointer. The transmission of pressure variations may be damped down by constrictions in the tubular connexion. A cock may be provided to enable internal and external pressures to be equalized when the device is out of action. The rod 11 may carry an inverted cup 19, preferably of india-rubber, to support the diaphragm 14.

Filed: 1975-01-24
Abstract: 1491192 Load-indicating fastener assembly ILLINOIS TOOL WORKS Inc 24 Jan 1975 [28 Jan 1974] 3100/75 Heading F2H A load-indicating fastener assembly, see Fig. 2, comprises a threaded member having a head with an integral bearing surface 16, a conical spring 22 which is pre-assembled with the shank, and an indicator 24 having a flange 26 and side wall 28 which acts to maintain the flange in a predetermined radial position between the bearing surface and spring 22, the arrangement being such that the indicator can rotate relatively to the spring until the flange is gripped between the bearing surface and spring by application thereto of a predetermined compressive load. An annular recess 17 may be formed in the bearing surface 16. Ribs may be provided on the undersurface of the spring. In a modification, the indicator is provided with circumferentially-spaced tabs extending radially inwardly from the side wall, instead of flange 26, (Fig. 6, not shown). In a further modification, see Fig. 7, the indicator 24b is provided with upper wall portions 34 which cover indicia 36 on the upper surface 18b of portion 14b and resilient strips 30 are formed from the side wall of the indicator to register in notches 32 spaced about the periphery of portion 14b, the strips biasing the indicator into a position relative to portion 14b such that portions 34 cover indicia 36. When torque is applied to the fastener 10b, a stage is reached when the lowermost flange of the indicator is gripped between the bearing surface and spring, after which, application of further torque causes the head to rotate relatively to the indicator against the bias exerted by the strips and exposes the indicia to indicate that a predetermined compressive load has been reached. In another modification (Figs. 10, 11, not shown), the indicator has tabs which extend inwardly from the upper part of the sidewall on to an upper surface of the head, thereby leaving gaps in the side wall engageable by a tool for sensing lack of freedom of rotation of the indicator.

Title: A method and apparatus for liberating starch from starch slush, fibres and fruit water by centrifugal separation
IPC: C08B30/04
Filed: 1945-02-08
Abstract: 588,313. Centrifugal separators. THORNTON, A. A. (Aktiebolaget Separator). Feb. 8, 1945, No. 3196. [Class 23] Starch is liberated from starch-slush, fibres and fruit water in a centrifugal drum 1 by means of radially-adjustable paring or skimming tools, 5, 10, which periodically scrape off the layer of starch slush and fibres and then remove the starch. The tools may be controlled by means of electric or hydraulic devices under the influence of a photo-electric cell 19 which reacts to the white surface of the starch when the latter is separated out during centrifuging. Inlet pipes 2, 3 supply starch milk and wash water periodically. A stirrer 4 is attached to the part 5, the combined tool travelling by a carrier on guide-bars 8, 9. The skimming tool 10 is arranged on an arm 12, which swings about a shaft 11, begin pressed on a nose 14, of the holder 7, by a spring 13. With the drum rotating, starch milk is supplied through the inlet 2, the members 4, 5, and a scraper 6 occupying their mid position (Fig. 1). The carrier 7 is then moved in direction a causing the stirrer 4 to enter into operation. A valve 15 is kept closed. After stirring, the carrier is brought back to mid-position for some minutes after which it is moved in direction b. The skimmer 10 at first moves ahead of the scraper 6 and skims off the fruit water collected closest to the centre until the arm 12 contacts a stop 16. The scraper 6 then moves past the skimmer 10 and scrapes off the layer of fibres and starch slush, which are discharged through the outlet17. The members 4, 5, 6 are then returned to their mid-position, the drum filled with pure water through the pipe 3, and the contents stirred by the stirrer 4. The valve 15 is opened and the tube 5 skims out water and starch. The starch may be washed several times before removal. Vanes 20 are provided in the inlet to the drum. The shapes of these may vary to vary the amount of slip on the rotating mixture in the drum. Tanks of starch milk and wash water may be supplied to the drum at intervals, automatically. The centrifuge is stated to have considerable momentum and may employ a flywheel.

Abstract: 769,804. Determination of physical response time lag. ROYAL SOCIETY FOR THE PREVENTION OF ACCIDENTS. Aug. 5, 1955 [Feb. 3, 1955], No. 3279/55. Class 81(2) In a reaction timing device the testing cycle is initiated by the patient and timing means is started simultaneously with the presentation of a stimulus. The timer is arrested by the patient in response to the stimulus. When electric power is supplied to :the circuit, Fig. 4, closure of switches C and A, by the two hands of the patient, drives a constant speed motor 7, which rotates an arm 10 over a series of contacts 28, 29 and these pass current alternately to green and amber lamps 21, 22. The contacts 30 in the remaining arc are connected to a red lamp 23 and, at the same time as the arm 10 reaches the first of these, a time indicating pointer is connected to the motor. In response to seeing the red lamp the patient releases switch C and depresses switch B and, during the interval between the two actions, the motor is kept running by parallel contacts 19 kept closed automatically over the arc of contacts 30. The motor and time indicator are stopped when B is pressed and lamps 14 are lit, through the lower contact of B, to make the timing indicator visible. A gear driven cam actuates a contact 17 so that when the switches are released the motor runs to a starting position unknown to the patient. The arrangement of the apparatus is shown in Fig. 2. The motor 7 drives a shaft 6 carrying the arm 10 over fixed contacts .9. It also carries a disc 8, having a toothed rack 11 over part of its surface so that, in rotating, it engages a pinion 12, driving a timing disc 24, at the same time that the arm 10 engages the first of the contacts connected to the red lamp. The three coloured lamps 21, 22, 23 are mounted behind a lens 2, so as to be visible to the patient, and the control switches, as C, are arranged at the front of the base. The contacts 19 are actuated by a cam surface 18 on the back of the disc 8 and contacts 17 by a cam 16 driven through reduction gearing 15 from the motor shaft 6.
