Title: Radioactivity measuring apparatus
IPC: G01T7/10
Filed: 1960-04-08
Abstract: 884,349. Rotary conveyers. PACKARD INSTRUMENT CO. Inc. April 8, 1960 [April 10 1959], No. 12657/60. Class 78 (1). [Also in Group XL (b)] Apparatus for measuring the radio-activity of a plurality of samples comprises a storage support to hold the individual samples in an arcuate array ranged round a common centre, at which centre the detector equipment is provided. Transport means are provided to transfer the samples one at a time from the support to the detector for measurement and then back to the support. The detector is mounted in a circular table 35 round which is supported in a rotatable manner on rollers 42 a drum 41 provided with a series of equi-spaced aligned holes in its flanges to support a plurality of samples 10. A motor-driven arm 45 supported above the table carries jaws 48 effective to transfer the samples to and from the detector. Normally, the jaws are urged together by a spring, but at each extremity of travel abutments on the jaws make contact with bearing surfaces and the jaws are opened. With the arm in its outermost position, as shown in Fig. 2 in full lines, energization of the drive motor causes arm 45 to move anticlockwise and, as it starts to move, jaws 48 close and grip the sample 10 positioned beneath them. The jaws are not mounted directly on the arm but are pivoted on a block 45b drawn inwardly by spring 56 and provided with a cam-follower 60. The latter follows cam 61 so shaped that the sample is drawn vertically out of the storage drum and hangs freely as it is then moved across to the centre. Towards the end of the movement the sample is directed vertically downwards into the detector opening and finally released by the jaws. Limit switches control the extent of the movement of arm 45 and a relay circuit (Fig. 6, not shown) is described which enables each sample to be automatically carried to the detector, left for a measuring period, replaced in the storage drum, and the drum then driven round one position for a repetition of the cycle with the next sample.

Title: Improvements in pumps for circulating liquor in coal and like gas purification plant
IPC: F04C11/00
Filed: 1936-05-05
Abstract: 473,083. Gear-wheel pumps. WILTON, T. O. May 5, 1936, No. 12662. [Class 110 (ii)] In a plant for circulating liquor in multibay gas-purifying apparatus, a separate gear pump is used for pumping liquor through each bay. The driving shafts 15 of the pumps are coupled by claw couplings 16 so that on removal of a casing cover, the rotors 4, 5, of one pump may be lifted out without disturbing the other pumps. Liquor enters a sump at the lower part of each pump, and leaves through an outlet above the pump, the inlet and outlet ports being connected to apparatus such as gas scrubbers. A spring- loaded byepass valve is placed so that excessive pressure on the outlet side will force open the valve and open the outlet chamber to the suction side of the pump. Sleeves 23 prevent lateral movement of the bearings 17, 20, 18, 21. Liquor leaking along the shafts passes through holes 26 to the suction side of a pump. Packing 25 is provided between each two pumps. In a modification, a separate sump for each pump is provided to collect leakage liquor. Pressure-equalizing holes may connect each two sumps above the levels of the liquor in each. The liquor may return to the bays under gravity or gas pressure.

[Also in Group VIII] A device for rectifying fabric wefts of the type having bent bars 3, 4, 5, 6, the orientation of the bend of which relative to the fabric passing therearound is variable, comprises two rectifying assemblies R1, R2 mounted on a rotatable shaft 7 and each having the same number of bars arranged about the shaft 7; a support 8 secured to the shaft 7 and on which the corresponding ends of the bars are journalled at 17 in end-to-end relationship; and means M1, M2 for obtaining in each assembly the variation in the orientation of the bend of the bars. The mechanisms M1, M2 each comprise a plate 18 keyed to the shaft 7 and having spindles 20, 21 journalled therein. The spindles 20, 21 carry cranks 9, 10 or 11, 12 to which the ends of the bars 3, 4 or 5, 6 are secured. Gears 24, 25 on the spindles 20, 21 mesh with a gear 26 fixed to a ring gear 27 freely rotatable on the shaft 7. A housing 30 is secured to the plate 18 and has a portion 31 secured to a hollow shaft 13 fixed to the stator 34 of a motor E1. The rotor 35 of the motor E1 drives, through a shaft 36, a shaft 37 rotatable within the shaft 13 and to which a sun gear 41 is keyed. A planet gear 42 freely mounted on the shaft 37 through a carrier 43 drives the gear 27 and a ring gear 44 on the housing 30. Devices F1, F2 are provided to stop the cranks 9, 10 after rotation through 180 degrees from the preceding stop position and each comprises a finger 46 projecting from a case 45 containing an electrical switch. As shown, the finger 46 of the device F1 is in contact with an abutment 47 on the gear 24 when the finger 46 of the device F2 is out of contact with the abutment 47 on the gear 25. In use, fabric is observed at the output end of the device. The operator actuates push-buttons (not shown) of each assembly R1, R2 to actuate the motors E1, E2 in either direction to adjust the bars 3, 4, 5, 6 to obtain the desired weft rectification. Each of the assemblies R1, R2 is acted on independently of the other. If the fabric speed is too great for observation the device may be controlled by a photo-electric inspection device as described in Specification 871,325.

Title: Improvements relating to lubrication systems
IPC: F16N21/04
Filed: 1946-04-26
Abstract: 633,763. Lubricating. TECALEMIT, Ltd., and LECLAIR, C. C. S. April 26, 1946; No. 12716. [Class 12 (iii)] An oil-hole nipple has a recess at its inlet end housing the upper part of a closure member of flexible and resilient lubricant-impervious material, such as rubber or synthetic rubber, having a needle pierced opening therethrough which is normally closed but opened to allow insertion of a grease-gun nozzle when pressure is applied around but away from the centre so as to flex the upper part of the closure member, there being a clearance between said upper part and the bottom of the recess. Fig. 1 shows a flanged nipple body 2 with enlarged bores 7, 8, adapted to house an axially-pierced H-section teat such that an axial clearance 14 exists to allow flexure of the upper part of the teat. A grease-gun discharge fitting hooked around the head of the nipple contains a hollow slidable piston assembly 30. A return-spring 35 reacts between a guide shoulder 27 of the discharge fitting and the underside of a flange 31 of the piston assembly such that normally the lower part of the piston assembly is flush with or within the base of the discharge fitting. A plunger type nozzle 39 having an axial bore 42 and slidably arranged within the piston assembly, is urged upwards against a sealing disc 38 at the top of the discharge fitting by a spring 43 reacting between the piston assembly 30 and a flange 41 on the plunger. In operation, grease pressure inside the discharge fitting first depresses the piston assembly, the lower cylindrical end of which distorts the teat and so opens its passageway for the subsequent entry of the nozzle. Circlips 45 and 46 respectively limit the depression of the piston assembly and the nozzle. Fig. 2 shows an alternative form of teat 19 having an upper flange 19 completely covering the nipple opening and with a holding rim 20 engaging in a recess 21 in the top of the nipple. This prevents jamming of the clearance space of the teat by entry of dirt. Various constructions of discharge fittings are described which are provided with clamping jaws or sleeves for securing and centring on the nipple. Specifications 430,827, [Group XXVIII], and 623,180 are referred to.

Title: Improvements in and relating to coupling devices for rotatable members
IPC: F16D3/62
Filed: 1941-10-02
Abstract: 577,489. Flexible couplings. TUSTIN, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 2, 1941, No. 12767. [Class 80 (i)] A flexible coupling between shafts 1, 2, comprises discs 3, 4, fixed to the shafts and having abutment pins 6, 7, which enter arcuate slots 8, 9, in a disc 5 mounted freely on one of the shafts. Spiral springs 10, 11, have their inner ends fixed to the hub of the disc 5, and their outer ends 13, 14 bear against blocks 15, 16, carried by the abutment pins 6, 7. The spring are prestressed so that when the torque transmitted through the coupling is below a predetermined value the abutments 6, 7, are held against one end of the slots 8, 9, as shown in Fig 2, and the coupling rotates solidly with the shafts. When this torque is exceeded the springs flex and relative movement occurs between the shafts 1, 2. The shafts reset themselves to the initial relative position when the torque again falls below the predetermined value. The coupling functions in both directions of rotation, and may be applied to the control device described in Specification 577,312, [Group XXXVII]. The coupling may act as a universal coupling to allow for axial misalignment of the shafts. The slots 8, 9, may extend more than 180 degrees and may overlap one another.

Abstract: 1,209,828. Looms; tensioning warps. SULZER BROS. Ltd. 15 March, 1968 [15 March, 1967], No. 12784/68. Heading D1E. For tensioning the warp threads a transverse rod 29 is reciprocated vertically by shaft 42 which is oscillated by cams 53-4 via a follower lever (49 fig. 4 not shown) and an adjustable connection allowing the threads to be tensioned by a predetermined extent. The warps are divided into two sheets by the rod and each is tensioned in alternate cycles at the closed shed position when the rod is at its highest or lowest. The hub of lever 49 is journalled on end 44 of the shaft 42 and has a flange (56) which engages flanges (57, 57') on hubs (46, 46') adjustably secured to the shaft. The initial spacing of flanges 57, 57' from flange 56 determine extent of movement of rod 29. The flanges may be so spaced that shaft 42 is rotated in one direction only, thereby tensioning one sheet only.

Abstract: 1,097,065. Fluid-pressure servomotor systems. KOEHLER-DAYTON Inc. March 25, 1965 [April 1, 1964], No.12787/65. Heading G3P. [Also in Divisions F2 and F4] A trailer 10 Fig. 1 is refrigerated by apparatus wherein gas above the solid carbon dioxide or the liquid nitrogen in a tank 16 enters the inlet chamber 57, Fig. 5 of a controller 30 via a manual valve 100 and a filter 99. The trailer temperature is set by adjusting the spring 70 of the controller, and is sensed by a liquid-vapour probe 35 connected to a bellows 115, which through a diaphragm 50 controls a ball valve 62 loaded by the spring 70, the valve 62 being in a passage between chamber 57 and an outlet chamber 51 which leads a pipe 31 and through the valve 33 to a diaphragm 37 connected to a spring-closed valve 20 in a pipe 17 leading from the liquid-containing part of tank 16 to spray nozzles 23 in the trailer. The chamber containing the diaphragm 37 has a restricted outlet to atmosphere. A pressure-relief valve 24 is in series with valve 20 both of the latter being associated with a by-pass containing a manual valve 21. The diaphragm 50 is acted upon by the pressure in the outlet chamber 51 from valve 62 resulting in a fixed outlet pressure for each probe temperature; the chamber 51 is connected to the space behind the diaphragm 50 by a needle valve 54. The latter also controls a vent 123. Pressure gauges are associated with the probe 35 and each of the inlet and outlet chambers of the controller 30. The liquid and gas containing parts of the tank are inter-connected by an evaporator 43, a shutoff valve 44 and a pressure regulator 40. If the valve 20 is of the spring-opened type the apparatus may be employed to control a heating system; the same effect is realised by reversing the action of the ball valve 62. The spray nozzles may be replaced by a heat exchanger.

Title: Improvements in Automatic Rifles.
IPC: F41A15/16
Filed: 1916-09-12
Abstract: 127,275. France, State of. Oct. 30, 1915, [Convention date]. No Patent granted (Sealing fee not paid). Breech actions, sliding barrel and breech-block. -Relates to long barrel-recoil rifles, and consists (a) in utilizing the gases to aid the recoil by providing the barrel casing with a cap extending beyond the muzzle and formed with a central aperture for the bullet, (b) of a special construction of the bolt and bolt-actuating means, and (c) of a special cartridge-feed mechanism. The barrel 4, Fig. 3, slides in a tubular casing 2 having at the front a cap 10 in which is an aperture for the passage of the bullet. On the barrel is a ring or piston 7 against which the gases act. The rotary bolt 15, Figs. 1 and 2, is actuated by a non- rotary striker sleeve 14 which has lugs 20 adapted to engage helical slots 23 in the bolt. Safety projections 24 and recesses 21 are provided on the bolt and sleeve respectively, registering to allow the sleeve to go fully forwards only when the bolt is locked. At the rear of the slots 23 is an annular groove into which the lugs 20 enter at a certain stage in the recoil and couple the striker sleeve 14 and bolt together above the striker sleeve, and moving therewith, is a pushrod 18 which engages the lowest cartridge in a semicircular magazine and feeds it forward during the breech-closing movement. The rod is coupled to the cocking-piece 17 by a catch 25, Fig. 1, which, near the completion of the closing movement, is disengaged by a cam-surface 37. The action of the gun is as follows : Assuming the parts to be in the position shown.in Figs. 1 and 2, with the breech open and the striker sleeve 14 held back by the sear 19, the bolt and striker sleeve will be then coupled together by the lugs 20 engaging the annular groove in the bolt. When the trigger is pulled, the sleeve 14 and bolt are driven forwards by a spring 35, the locking-lugs 22 on the front of the bolt sliding along grooves 11 in the breech-body 5. Near the front, these grooves are formed with a helical portion, as shown in Fig. 2, which rotates the bolt sufficiently to move the lugs 20 on the striker sleeve from the annular groove into the helical slots 23. The striker then continues its forward movement and rotates the bolt into the locking position, and then fires the cartridge. The barrel 4, breech-body 5, bolt 15, and striker sleeve 14 then recoil together until the sleeve 14 is caught by the sear 19. The barrel, body 5, and bolt are then moved forwards by the 'barrel return-spring 9, Fig. 3, until the bolt is unlocked by the action of the lugs 20 on the helical slots 23. The barrel and body then run out alone, the first part of the movement rotating the bolt, by means of the helical portion of the slots 11, to couple it to the sleeve 14.
