Title: Device for regulating the cooling of an air-cooled internal combustion engine
IPC: F01P7/08
Filed: 1968-12-05
Abstract: 1,219,000. Air-cooled engines. DAIMLERBENZ A.G. Dec. 5, 1968 [Dec. 7, 1967], No. 57783/68 Heading F1B. [Also in Division F2] The speed of a cooling-air fan 2 Fig. 1, of an air-cooled engine is controlled by a thermostat 7 which controls a slip clutch in the driving gear of the fan, the thermostat being arranged in the cylinder head near the combustion chamber. The thermostat is preferably arranged in a base 14 in a part of the head adjacent the hot portion 11 between the valve ports and on the side of the head against which the cooling air blows. In the four cylinder engine shown in Fig. 1 separate thermostats 7, 8, are provided in the two cylinders 4, 6. The thermostats are of the expansible fluid type and are connected to a joint bellows 16, Fig. 4, mounted on a rigid member 18 and connected to a second bellows 17. Upon increasing temperature bellows 16 expands to move the clutch control lever 10 but if a leak develops in the thermostat system, both bellows 16, 17 contract and an arm carried by bellows 17 contacts lever 10 to move it to a position of high fan speed. In Fig. 6 the cylinder head thermostat 20 is connected to a bellows 21 whilst a thermostat 23 in the circuit of an oil cooler operates a normally inoperative bellows. If e.g. at low load high speed conditions bellows 21 contracts to reduce fan speed to a level such that the oil cooler cannot maintain the oil temperature below a predetermined value bellows 22 expands and operates level 10 through bellows 21, or a rod 24 carried thereby, to increase the fan speed. In a modification the bellows 20, 23, are in parallel and act separately on the lever 10. (For Figures see next page)

Filed: 1971-12-17
Abstract: 1369834 Purifying hydrogen GRUPUL INDUSTRIAL DE CHIMIE 17 Dec 1971 58788/71 Heading C1A [Also in Division C7] Hydrogen produced by electrolysis is treated so as to remove any alkali material carried with it by moistening the gas with water and passing it through a cation exchange resin in its hydrogen form. After use and before subsequent reuse the water with which the gas is moistened may be passed through an anion exchange resin to maintain its pH approximately neutral. The process is said to work on hydrogen containing 1 to 20 mg. NaOH/Nm<3>.

The homopolymerization of cyclooctadiene and of cyclododecatriene and the copolymerization thereof are preferred procedures using the second class of monomers.
Patent GB-707804-A (GB)
Abstract: 707.804. Calculating-apparatus. ATELIERS VAUCANSON. Feb. 28, 1952 [March 1, 1951; Feb. 8, 1952], No. 5305/52. Class 106 (1) A reversing gear between the revolution counter and repeating drums of an Odhner machine comprises a pair of pinions 15, 16 secured to an auxiliary shaft 13, the pinion 15 constantly meshing with a pinion 9 on the shaft 4 of the counter, and the pinion 16 being adapted to make driving connection with a pinion 10 on the drum shaft 7 either directly or through a reversing pinion 11 according to the axial setting of the shaft 13. In Fig. 1, the drive is from the reversible drum shaft 7 to the shaft 4, the reversing gear enabling the counter to be driven in the same direction whichever way the drum is rotated. Axial adjustment of the shaft 13 to effect reversal is by a fork 17 slidable with a rod 18 and secured in its two alternative positions by engagement of a spring 22 in grooves 21 of a boss 20 on the rod. In Fig. 5, the drive is from the shaft 4 of the counter to the drum shaft 7, the reversing gear controlling the direction of rotation of the drum. The pinions 15, 16 are solid with a sleeve 13 slidable on a rod 25 by means of a lever 26 connected to a slide 30. A transverse slide 32 normally retains the slide 30 against the action of a spring 31 in the position for direct engagement of the gears 16 and 10. When the transverse slide 32 is displaced, an aperture therein releases the slide 30 and the pinions 15, 16 are shifted so that transmission occurs through the reversing pinion 11. A stop 23, Fig. 1, prevents shift of the gears except when a clearance slot 24 in the gear 16 registers with the stop in the normal positions of the repeating drums and counter.

Abstract: 751,788. Gear pumps. HOBOURN-EATON MANUFACTURING CO., Ltd. March 11, 1954 [June 17, 1953], No. 7108/54. Class 110(2) A gear pump with internally meshing rotors with n and n+1 lobes has its external rotor 14 mounted in an eccentric sleeve 32 or 58 which has its internal and external peripheries eccentric to one another and which may be rotated, adjusting the eccentricity between the rotors 12, 14, to establish the proper nose clearance between the teeth of the rotors. The sleeve 32 is fixed in its adjusted position by a pin 44 inserted between a groove 42 in the housing 16 and one of the grooves 40 in the sleeve 32. Another method of fixing the sleeve is by inserting a rubber ring 66, Fig. 3, in a groove 64 in the end of the housing 60 and squashing it with the end plate 46 between the housing 60 and the serration (Fig. 4, not shown) round at least part of the outer periphery of the sleeve 58. The rotor 12 is keyed by a cylindrical pin 34 to a shaft 28 which is journalled eccentrically to the pump pocket 18 and carries a sealing ring 54.

Title: Hot melt glue applicator
IPC: B29C31/04
Filed: 1978-09-06
Abstract: A hot melt glue applicator, has a heated reservoir 10 from which glue passes along a channel 24, 25, 26, respectively in plates 15 and 16 and nozzle block 14, heated by rod 19 passing through holes 20, 21, 22. Glue passes along channel 27 to recess 28 containing gears 29, 30 constituting a gear pump. Passage of a workpiece between milled wheel 66 and back-up wheel 67 rotates wheel 66, and consequently axle 31 and gears 29, 30 of the gear pump, so that hot glue is pumped under pressure to tubes 32, 34 and thus to nozzle sockets 38, 39; the glue overcomes the pressure of spring 48 on ball 49, and issues from nozzle 47 on to the workpiece. When the workpiece ceases to rotate wheel 66, the gear pump stops, and the nozzles are closed by the spring-loaded ball valves 49 therein. Nozzle sockets 38, 39 can be blanked off as desired by plugs 40. <IMAGE>

Patent GB-2038173-A (GB)
Title: Height adjustable table tops
IPC: A47B9/18
Filed: 1979-09-18
Abstract: A table has a table top the height of which can be adjusted between an elevated position and a lower position so that the table can be used, for example, both as a billiards table and as a domestic dining table or a table tennis table. Adjustment of the height of the table top is effected with a mechanism, incorporating a support member (10) which can be moved from a retracted position, as shown, into an extended position at which it acts to support the elevated table top (1) on a support structure (2). This movement of the support member (10) is effected on lifting of the table top by engagement of a cam follower (15) with a cam surface (21). Lifting of the table top beyond the elevated position may act to return the support member (10) to its retracted position via engagement of a further cam follower (16) with a further cam surface (25). <IMAGE>

Abstract: A bird shower comprises a shower head 4 arranged above a shower base 1 in the form of a water reservoir, and a perch in the form of a bath 2 pivotally mounted on the base 1 and biassed by a spring 28 into a raised position. When a bird alights on perch bar 16, the bath 2 pivots downwardly so that a permanent magnet 37 thereon operates a reed relay 36 to switch on an electric pump (29), Fig. 4 (not shown), which then pumps water from the base 1 to the shower head 4. When the bird leaves the perch, the bath 2 moves back to its raised position under the action of the spring 28, the magnet 37 operating the reed relay 36 to switch off the pump. <IMAGE>

Patent GB-2045380-A (GB)
Title: Clutch release bearing assembly
IPC: F16D23/14
Filed: 1980-02-14
Abstract: A clutch release bearing assembly comprises a composite guide sleeve 19 in the form of an annular metal disc-like part 20 which is surface hardened and on to which is moulded a cylindrical part 18 made of filled plastics material. A resilient self- aligning action of the assembly is ensured by an elastomeric sleeve 16 which comprises a number of radial ribs 17 which are in contact with the outer surface of the guide sleeve 19. The outer surface of the sleeve 16 carries the inner ring 1 of a ball bearing 4 and the outer ring 10 of the bearing acts on the clutch to disengage it. The plastics part 18 ensures that the assembly can slide freely on a guide tube 13 while the hardened metal part 20 takes the thrust from a clutch operating fork and resists wear. The part 20 also helps, by its contact with the fork, to hold the axis of the assembly parallel to the axis of the guide tube 13 and prevent the assembly from rocking when it is operated. <IMAGE>
