Title: Hydraulic backlash adjusters for overhead cam shaft engines
IPC: F01L1/24
Filed: 1972-12-15
Abstract: 1357080 IC engine valve gear JOHNSON PRODUCTS Inc 15 Dec 1972 [24 Feb 1972] 57993/72 Heading F1B [Also in Division F2] An hydraulic automatic back-lash adjuster pillar 16 providing zero lash for an overhead cam-shaft I.C. engine valve operating mechanism of the type in which a rocker arm 8 has one end 14 pivotally mounted on a plunger 20 extending from the adjuster pillar 16, the other end engaging a valve stem 2, and a portion of its upper surface between its ends engaging a cam 10, comprises a hollow body 18 containing the reciprocable plunger 20 which includes a ball valve 50 and seat 48 interposed between a cavity 24 and outlet passage 47 therein. Engine lubricating oil enters the cavity 24 via ports 36 and 38 in the side walls of the body 18 and plunger 20 respectively, the oil passing through the bottom opening 32 of the plunger 20 and via a valve plate 28 into a compression chamber 26. The ball valve 50 is arranged to remain in an open condition off the seat when air is present in the cavity 24 and to close on to the seat 48 when oil flows in the cavity 24 and approaches the seat 48. As shown, the ball 50 is freely supported closely below the seat by a spring retainer 56 whilst in Fig.4 (not shown), the retainer is in the form of a hollow pin (58) through which the oil is fed to the cavity 24. In Fig.7 (not shown) no retainer is required, the ball (50') being hollow and/or of plastics and having a specific gravity less than that of the lubricating oil and greater than that of air so that it floats on the oil. A flow passage 60 Fig.1 and Fig.5 (not shown) is positioned adjacent the seat 48 so that, in use, when the ball valve 50 is closed oil may flow past the ball valve 50 and, via passage 47, lubricate the pivot head of the plunger 20 and cam follower socket 14. Alternatively, the flow passage may be effected around the edges of an eliptically shaped apertured disc (62) Fig. 6 (not shown) which is warped slightly when assembled into the cavity 24 to form the valve seat.

The wafer may be mounted on a support 42 with a heat sink 44. The conductive leads may include pointed ends, which may be mounted on a circuit board, the package being placed over the leads so that the ends make contact with the foil via apertures 14. The lead ends may be bonded to the foil, again by soldering. The dielectric layers may be of alumina ceramic, the foil of an aluminium coated cobalt-iron-nickel alloy; or a copper-iron-nickel alloy. The conductive leads may be of brass, stainless steel or copper. The foil may be patterned by photoresist and etching methods. In an alternative embodiment, a plurality of dielectric layers with wafers may be stacked one upon another with aligned apertures, connection being made between the foils by leads having pointed ends.

Abstract: 601,863. Perforating - machines for tickets. SLOPER & CO., Ltd., J., and FIRMINGER, R. T. Oct. 9, 1945, No. 26290. [Class 31(ii)] A dating or like press for perforating tickets with numerals or other symbols is constructed with a pivoted pendulum arm 11 in which a die-block, Fig. 6, is mounted detachably, the block being provided with groups of pins or punches 3, and the number printed by each group is determined by means of flat key plates 22, Fig. 2, which are secured in a holder 15 detachably secured to a plunger 12 which is given an axial movement relatively to the arm 11 when the arm 11 is moved towards its supporting arm 9 after the ticket to be dated is inserted into a slot 5, Fig. 6, which separates the punches 3 from a matrix 4. The key plates 22 are constructed with solid portions, to engage the required punches 3 to make up a numeral &c., and with apertures in register with the punches not required to operate. The key plates 22 are formed with slots 24 for receiving teeth 34 on a locking lever 32 which holds the plates in position when these are inserted in slots 17 formed in a holder 15, Fig. 9, carried by the plunger 12, strengthening ribs 25 on the plates being preferably employed and adapted to register with slots 46 in the holder 15.

Title: Storing liquefied gases
IPC: F17C13/12
Filed: 1979-05-10
Abstract: The area 3 around a tank for storing liquefied gases is provided with loose pieces of heat-insulating material 5, preferably pieces of foamed glass. In case of failure of the tank, the pieces of heat-insulating material will float on the liquefied gas flowing into the area, so that the surface of the liquefied gas will be blanketed by the heat- insulating material. The floating heat-insulating material reduces evaporation of the liquefied gas and in the case of a fire in the area, the fire is suppressed by the floating heat-insulating material. Freezing of the heat-insulating material onto the bottom of the bund area is prevented by the presence of a thin flexible material, preferably polyethylene sheet material, between the said bottom and the heat-insulating material. <IMAGE>
