Filed: 1962-11-05
Abstract: 970,286. Vehicle loadhandling tail board. ANTHONY CO. Nov. 5, 1962, No. 41691/62. Heading B8E. A tailgate apparatus for raising and lowering loads as described in Specification 711,241 has in addition to first latching means as described therein for holding the platform in its raised position second latching means, for holding the platform in the truck-closing position, which co-operate with the first latching means to prevent their accidental unlatching when the platform is in the truck-closing position. As in the prior Specification the first latch means comprise members 42, 43, Fig. 6, mounted on a control shaft 41, which co-operate with members on two of the arms supporting the platform 5, but in addition the shaft mounts members 69, 70 of the second latch means which can be engaged by members 68 secured to frame members of the lifting mechanism. With the tailgate platform 5 in the truck-closing position, Fig. 2, a movement of the control lever 54 to unlatch the first latching members is prevented since this movement would involve rotation of the control shaft 41 which also mounts the members 69 of the second latching means and these latter members are prevented from moving by engagement with the surface 70 of the members 68. With the platform lowered to the horizontal raised position the arms 24, 25 are telescoped thus disengaging the latch members 68, 69 and allowing rotation of the control shaft 41 to unlatch the first latching means. U.S.A. Specification 2,684,770 also is referred to.

Abstract: 1,268,087. Feeding sheets. INTERNATIONAL STANDARD ELECTRIC CORP. 21 Aug., 1969 [23 Aug., 1968], No. 41691/69. Heading B8R. When a sheet previously separated from a pile stacked on edge in a magazine 67, Fig. 1, passes beyond the path of light from a lamp 28, Fig. 2, to a photo-cell 42, Fig. 3, a valve 2 connects a source of suction to a cavity 7 containing freely rotatable rollers 10, 11, 12, whereupon the next sheet 68 is drawn against a perforated belt 31 running in contact with the rollers and is separated from the pile and fed by the belt. When the sheet reaches the light path, the valve connects the cavity 7 to atmosphere, while the sheet is forwarded frictionally by the belt co-operating with a roller 49. Separation is assisted by air directed downwardly from openings 26 on to the upper edges of the front sheets. Sheets other than the end sheet are prevented from being separated with the end sheet by air from pressure chambers 59 blown through channels 60 and thence in a direction opposite to feed direction between the belt and the magazine. Any sheets which nevertheless do stick to the end sheet are thereafter pressed against a wall 43 by suction applied from a chamber 52 to cavities 50 in the wall and by air from a pressure chamber 21 blown through openings 20, so as to prevent further passage of such sheets.

A service carriage runs on the frame of a double twisting machine and carries a knotting device level with the thread feed tube 9 of a double twisting spindle 10. Member 13, e.g. of plastics or leather and of circular cross-section is connected to the rod 15 of a pneumatically operated piston in a cylinder 14 and a tension spring 16 attached to carriage 4. During knotting, yarn ends are placed between metal pieces 26, 27 and lever 20 is moved upwards so that air under pres-  sure is fed to cylinder 14 and a stop pin 24 is released from a notch 29 in a cam wheel 25. Thus member 13 is pulled down and shaft 11 is rotated until pin 14 again engages notch 29 when cylinder 14 is vented. Rod 15 is retracted and spring 16 pulls member 13 back and in the absence of any tension in the member, shaft 11 is not rotated. A doubleacting cylinder may be used so that rod 15 is returned positively by compressed air.

Title: Instruments for detecting and or measuring amounts of contaminant contained in a liquid
IPC: G01N21/53
Filed: 1970-09-03
Abstract: 1319804 Optical sample cells TOKYO KEIKI KK 3 Sept 1970 [8 Sept 1969] 42236/70 Heading G2J [Also in Division G1] Contaminants, e.g. bubbles and solid particles, in a liquid, are determined by flowing the liquid through a cell 1 illuminated with parallel light and comparing the responses of a detector 3 receiving transmitted light and a detector 4 receiving scattered light. These detectors which may be CdS photo-resistors, form adjacent arms of a bridge arrangement. The bridge is first balanced with an uncontaminated liquid flowing through the cell. Then the test liquid is flowed through the cell and the change in bridge voltage displayed on a meter indicates the new contamination level. A throttle device T is provided in the exit tube to enable the liquid to be pressurized and hence remove the bubbles. In this way the contaminant levels due to bubbles and to solids can be assessed separately. In an embodiment for measuring contaminants in an oil pumping system Fig. 2 (not shown), during this pressurizing step the flow of liquid is actually stopped.

Filed: 1972-09-13
Abstract: 1391495 Refrigerating ARKLA INDUSTRIES Inc 13 Sept 1972 42499/72 Heading F4H [Also in Division G3] Excessive steam flow to the refrigerant vapour generator 24 of a salt solution absorption refrigerator is prevented by a valve 50 responsive to means for measuring the steam flow. The steam line 52 contains an orifice plate 96 to produce a pressure difference controlling a diaphragm actuated pilot valve 66 receiving its fluid supply from a further pilot valve 64 controlled by the pressure upstream of the plate and by the temperature difference between the inlet and outlet of a chilled water coil 14 of an evaporator absorber 10, the chilled water being used to air-condition a building. The temperatures are sensed by resistance bulbs 82, 84 connected to a bridge and amplification unit 80 producing an output signal more effected by the outlet than by the inlet temperature and operating the valve 64 through a motor having a vertically-driven shaft 74. The refrigerant vapour driven off in the generator 24 is condensed in a condenser 30 before entering the evaporator-absorber 10 when it is mixed with a salt solution weak in refrigerant returned through a heat exchanger 22 from the generator. A pump 20 supplies the generator with a solution strong in refrigerant from the evaporatorabsorber. A cooling water coil 38 in the latter is connected in series with a similar coil 40 in the condenser.
