IPC: B60G15/04
Filed: 1922-08-08
Abstract: 198,597. Hassler, R. H. Aug. 8, 1922. Vibration-dampers.-A retarding check device carried by one of two relatively movable vehicle parts, namely the frame and an axle, is connected to the other vehicle part by a device comprising a rigid floating member and a pliable connector arranged between the rigid member and the check device or said other part, or both. This connection provides for a certain amount of lost motion so that the check device remains inactive during small vibrations. As shown in Fig. 8, the check device comprises a hub 19 connected to the frame bv a bolt 21 and formed with a disc member 19<a> carrying a friction disc 16. A second friction disc 26 is carried by a disc 24 arranged to move axially but not angularly relatively to the disc 19<a>. The friction discs 16, 26 are forced outwards by a spring 28 against a part 17 and cover plate 30 carried by an actuating arm 23 which rotates on the pivot 18 and is connected to the axle by the floating member 39, Fig. 1, and pliable connectors 34, 42 which preferablv comprise layers of fabric &c. The connectors are clamped between wings 39<a> at the ends of member 39, the upper connectors 34 being clamped between a plate 35 and the end of the arm 23, while the lower connector 42 is clamped between a plate 44 and an axle bracket 46. The edges of the parts between which the connectors are clamped are curved as shown. In the modification shown in Fig. 10, a flanged spool 50 is inserted between the layers of the pliable connector to enable the layers to separate symmetrically when under compression.

Title: Improvements in splash guards for vehicle wheels
IPC: B62D25/18
Filed: 1928-07-25
Abstract: 307,264. Schneider, A. July 25, 1928. Lateral-splash guards for vehicle wheels comprise two brushes 20, 28 carried one behind the other as shown by pivotal arms comprising rods 17, 26, which telescope in sleeves 16, 25 respectively under the control of springs therein, the telescopic arms passing through a slot in the bottom of a casing 1 mounted on the wheel hub or axle. The casing 1 may be attached to the wheel hub by means of a projecting boss mounted on a ball bearing 14. The casing 1 is normally held in a horizontal position by a stay 11 pivoted at 12 to the mud-guard 10 and slidably engaging an eye 13 on the casing, the lower end being connected by a spring 8 and a cord 6 to a point 7 on the casing, which is thus rocked on the hub to raise the front brush 28 from the ground when the vehicle body is displaced towards the wheel by irregularities of the road surface. The sleeve 16 is carried by a ring 15 rotatably mounted on the ball-bearing element, and the sleeve 25 is pivoted to a bar 23, the upper end of which is pivoted at 24 to the casing, a spring 31 maintaining the sleeve 25 and the bar 23 normally in alignment. The bar 23 is connected by a link 22 to an arm 21 on the sleeve 16, so that rocking movement will be imparted from one brush holder to the other on contact with obstructions. A spring 30 connected at one end to the casing and at the other end to an arm 30<1> on the ring 15 holds both brushes normally in their forward position, and rearward deflection is limited by a rubber buffer 38 adapted to engage the sleeve 16. The slot in the bottom of the casing 1 is protected by brushes to prevent the entry of mud. The outer eide of the casing is closed by a cover, which can be removed for cleaning or lubrication. The brush bristles are secured to flat plates 19, 27 which are provided with auxiliary splash-arresting plates 36 hinged on rods 35, so as to be raised by the action of water on gills 37 when the wheel passes through a puddle.
Patent GB-659601-A (GB)
Title: Improvements in selection circuits
IPC: A47F10/00
Filed: 1949-08-19
Abstract: 659,601. Selective control. COMMUNICATION ENGINEERING PTY., Ltd. Aug. 19, 1949, No. 21631. Convention date, Sept. 24, 1948. [Class 40 (i)] [Also in Group XVIII] A three-digit selecting system comprises a key strip of ten keys, up to ten hundreds relays, a corresponding number of groups of tens relays and a single set of ten units relays. The operated hundreds relay selects a particular group of tens relays for actuation by the second digit and the operated tens relay closes ten contacts, one only of which is rendered effective by the operated units relay. The invention is described with reference to an articledispensing system, the units relays controlling the dispensing devices via a jumpering frame so that a particular type of article may retain its code although the container from which it is dispensed has been changed. The first operation of a key K0 ... K9 in the selection of an article energizes one of the hundreds relays 0F, 3F, &c. in series with its individually fused pilot relay 0FP, 3FP, &c., which energizes a slow to release relay FA. The hundreds relay locks up but the pilot relay falls when the key is released and energizes change-over relay FC which locks up- Shortly afterwards FA falls. The next key opera. tion thus energizes one of the relays in the selected group 00S ... 09S, 10S ... 19S (not shown), &c. in series with a pilot relay 0SP &c. which energizes a slow to release relay SA. The tens relay locks up, closing ten contacts connected to terminals on the jumpering frame and on the release of the key, the pilot relay and relay SA fall in succession making a momentary circuit for changeover relay SC which locks up. The third operation of a key thus energizes one of the units relays 0T ... 9T in series with a relay TP and these relays jointly complete a circuit over one of the contacts closed by the tens relay and the jumpering frame for one of the relays 1CR, 2CR and in series with a relay C. The relay 1CR &c energizes the dispensing mechanism and locks up until the latter has operated. The relay C energizes CA which releases the units relay, locks up and causes the relapse of C when the dispensing operation is complete to energize a relay R which unlocks all operated relays and then falls back itself. Relay R can also be operated by a cancel key CK to wipe out the effect of an incorrect key operation.

Title: Sleeve lined plug valves
IPC: F16K5/02
Filed: 1961-06-16
Abstract: 990,976. Valves. DURIRON CO. Inc. June 16, 1961 [June 24, 1960], No. 21871/61. Heading F2V. A sleeve lined plug valve comprises a metal housing 20, Fig. 1, with a metal tapered plug 50 having a through bore 52. A fluorocarbon liner, of greater coefficient of expansion than the body and plug, is provided in the housing which housing is provided with grooves 31, 36 Fig. 2 and recesses 40, 41 which are bordered by lands 32, 37, 42, 43, 44. To assemble the valve, the liner is pushed into the housing and the valve plug or a blank plug is forced in a predetermined distance, thus causing some cold flow of the liner into the grooves and recesses. The assembly is then heated to a temperature above normal use, such as 425‹ F., when further flow of liner material takes place. The assembly is then cooled and the plug removed to allow cleaning. The grooves and recesses thus hold the liner under tension and prevent axial or rotational movement of the liner. The valve plug is then assembled to the required position. The spindle 60 may be provided as shown, or may be at the smaller end of the plug. The through passage 52 in the plug may be tapered. Specification 910,536 is referred to.

Patent GB-221192-A (GB)
Abstract: 221,192. Seguin, L., and Seguin, A. Aug. 29, 1923, [Convention date]. Addition to 215,706. No Patent granted (Sealing fee not paid). Adding and subtracting apparatus with operating-means.-In the machine described in the parent Specification, means are provided to enable subtraction to be performed by turning the driving-handle in the opposite direction and the frictional mounting of the totalizer wheels and the stopping- members is supplemented by the use of spring-controlled detents. Driving-mechanism. The crank handle 114 oscillated about shaft 110 in the direction F for addition, and in the direction F<1> for subtraction, is fast with a sector 113 gearing with a pinion 117 secured to the totalizer shaft 4. Loose upon shaft 110 are two toothed sectors 111, 112 gearing respectively with idle pinion 118 meshing with pinion 115 fixed to shaft 5, and with pinion 116 also fixed to this shaft. Abutment surfaces 121, 122 on the sectors 111, 112 engage on opposite sides with a pin 123 carried by the sector 113 and this engagement is ensured at all times by a spring 124 secured to sector 112. It can be seen from this arrangement of gearing that shaft 5 is always driven in the one direction irrespective of the direction of oscillation of the handle, and that the totalizer shaft 4 changes its sense of rotation with change of oscillation of the handle. Mounting of totalizer wheels &c. on their shafts. Each totalizer wheel may be provided with a spring-controlled detent in the form of a ball 210 or of a sliding bolt 206 co-operating with notches 200 in the shaft, and a similar arrangement may be adopted in the mounting of the members 12 on their shaft 5. Transfer-mechanism.-The transfer tooth 44 on the lower wheel co-operates at transfer with a double-wedge surface 104 formed on a tappet 101 pivoted at 102 and controlled bv a spring 103. If the higher wheel is rotating when transfer to it occurs the depression of the tappet bv the tooth 44 causes a tooth 105 momentarily to engage a toothed sector 17 integral with the stop-member 12 so that the return movement of this member to engage the totalizer is delayed to the extent of permitting the addition or subtraction of unity on the higher wheel. If this wheel is stationary at transfer, the downward motion of the tappet effects through its extension 106 an outward displacement of the member 12 to allow the higher wheel to rotate through one division. To ensure positive connection between the lower totalizer wheel and shaft 4 during transfer, the transfer tooth may be pivotally or slidably mounted on its wheel, as shown in Figs. 4 and 5, so that at transfer its abutment against the tappet causes it to rock or slide into locking engagement with the notches 200 formed in the shaft.

Filed: 1956-07-18
Abstract: In apparatus for stripping gaseous fission products from a liquid, e.g. effluent cooling liquid from a nuclear reactor, the liquid enters through pipe 13 and descends as a film over former 22, passing up into recess 24 and through openings 21 into discharge tube 2; the openings 21 act <PICT:0793905/III/1> as a weir to maintain a liquid seal in the vessel.  Helium or other non-radioactive carrier gas enters through pipe 27, flows concurrently with the liquid film through passage 29 and leaves, together with gas liberated from the liquid, via openings 30, passage 16, and pipe 31 to a detection chamber where the intensity of beta and gamma radiations is measured. The carrier gas may be recirculated after removal of the fission products.  Other methods of separating the gases from the liquid are to bubble the carrier gas through the liquid or to spray the liquid into the gas; alternatively the liquid may be boiled to liberate the gas, the vapour of the liquid being condensed or used as the carrier gas.

IPC: G01N21/53
Filed: 1964-06-01
Abstract: 1,074,251. Photo-electric turbidometers. CENTRAL ELECTRICITY GENERATING BOARD and I.J. CONIBEAR. May 31, 1965 [June 1, 1964], No. 22552/64. Headings G1A and G1X. The dust burden of smoky gas passing along a duct is measured by determining the difference in output of two photo-cells, one receiving light which has passed through smoke and dust and the other receiving light that has passed through smoke from which at least part of the dust has been removed. CdS photo-resistors 1, 2, Fig. 1, receive light from lamps 9 and 10 across the duct 4. A tube 12 across the duct has shielded holes 13 which admit smoke but not dust to affect the transmission of light to the photo-resistor 1. The photo-resistors are connected to a stabilized supply and their mid point is connected to a recorder through a cathode follower and an antilog circuit. In a modification, Fig. 3 (not shown) the tube 12 is replaced by a semi-cylindrical baffle down stream of which is a region of low pressure into which only smoke and the smaller dust particles penetrate. This penetration of small dust particles tends to compensate for their greater obstruction of light compared weight for weight with large particles. The baffle is mounted to be removed from the light path for calibration. The two beams of light may be derived from a single light source by prisms, in which case the sum of the cells outputs may be maintained constant by varying the light source intensity.
