Abstract: 1324146 Photo-sensitive materials and receiving sheets containing cresols NASHUA CORP 7 May 1971 [13 May 1970] 13679/71 Heading G2C  A material suitable as a receiving sheet in a photographic process comprises a support coated with a layer containing a non-light-sensitive, reducible silver salt and 2, 6-dicyclohexylcresol, the amount of cresol being less than that required to reduce the silver salt on heating except in the presence of another reducing agent. The material is preferably used as the receiving sheet in the processes disclosed in Specification 1002350, 1280593 and 1296969 wherein a sheet containing a reducing agent (e.g. a naphthol, a nitrile or a pyrazolinone) is imagewise exposed to light to render the reducing agent inactive in the exposed areas and then placed in contact with the above receiving sheet whilst heating to transfer the remaining reducing agent and produce a coloured image. Alternatively, the material may contain a binder (e. g. polyvinyl butyral) and a lightinactivatable reducing agent so that a colour image may be produced on imagewise exposure and heating without transfer. A dye may also be present to extend the sensitivity into the visible spectrum.

Title: Improvements in or relating to processes and apparatus for the purification of gases
IPC: C10K1/08
Filed: 1924-06-10
Abstract: 235,126. Koppers Co., (Assiguees of Sperr, F. W.). June. 6, 1924, [Convention date]. Sulphur. - In the purification of gases and more particularly in the removal of hydrogen sulphide from coal gas and like fuel gases according to which the impurities in the gas are transferred to air which is then washed with a liquid which may be regenerated by treatment with air, as described in Specification 241,248, the last trace of impurities is removed by subjecting the gas to a second washing with freshly-regenerated air washing liquid. About 90 per cent of the hydrogen sulphide is removed by treating the gas with a solution of sodium carbonate in a scrubber 1 into which the gas passes from air inlet 2 to an outlet 4. This sodium carbonate solution is then sprayed into an actifier 7, in which it is revivified by air from a blower 12 the solution being again pumped through a pipe 3 to the scrubber 1, and the air carrying the hydrogen sulphide passes by a pipe 13 to a scrubber 14 in which it is treated with a liquid containing an iron compound preferably a dilute solution of sodium carbonate containing freshly-precipitated ferric carbonate. This air washing liquid which passes through the scrubber 14 in the same direction as the air as described in Specification 235,125 is regenerated in a sump 19 by air jets 20 which bring the sulphur to the surface from which it is skimmed and dried in a centifruge 28. The regenerated liquid is pumped through a pipe 32 to the top of a scrubber 30 through which the partly purified gas passes from the inlet of the pipe 4 to an outlet 31, this second washing extracting the remaining hydrogen sulphide, and the washing liquid passing by pipe 15 to the air scrubber 14. Specification 190,117, [Class 55 (ii), Gas manufacture &c.], also is referred to.

Title: Improvements in moulds for casting concrete pipe-joints
IPC: F16L1/038
Filed: 1920-05-21
Abstract: 163,212. Hughes, J., and Sparrow, C. S. May 21, 1920. Casting pipes and tubes.-A mould for concrete pipe joints comprises (1) a pair of side walls D, E, embracing respectively the ends A, B of a pair of juxtaposed concrete pipes, each wall comprising two or more arcuate portions bolted together as at J, and (2) a flexible member K, encircling the side walls and clampable in tight contact therewith, for example, by means of bolts M. The walls D, E may be of metal, or of wood mounted on iron straps F, G, and the member K of flexible steel band shorter in length than the outer periphery of the walls D, E in order to leave a gap for introducing fluid concrete for forming the joint. A sealing-ring C of bitumen is provided, and the joint may be reinforced by the usual steel ring O and bars P, secured by wedges prior to fitting the mould round the pipes. The mould is designed so that it may be fixed without displacing the reinforcing-members, and be disassembled when the jointing collar has set without fear of damaging the collar.

Title: Improvements in or relating to centrifugal speed regulating systems for internal combustion engines
IPC: F02D9/00
Filed: 1957-05-02
Abstract: 821,739. Speed governors. VYZKUMNY USTAV NAFTOVYCH MOTORU, and ZAPLETAL, M. May 2, 1957 [May 3, 1956], No. 14094/57. Class 57. A speed-regulating system for internalcombustion engines comprises a first mechanism A transmitting the motion of a centrifugal governor to the control rod of a fuel injection pump 16, a second mechanism B for adjusting the governor loading and a third mechanism C, operatively associated with the first and second mechanisms, for varying the quantity of fuel delivered and controlled by means operable by the second mechanism so that the fuel supply varies from a maximum value at starting to a minimum value at minimum engine speed and then back to the maximum value at maximum engine speed. The governor is loaded by a spring 4 adjustable by a rod 9 through a lever 8, rod 7, lever 6 and rod 5 and the movement of the governor sleeve 3 is transmitted to the pump 16 through a system of levers including a lever 11 pivoted on a pivot 11<1> movable by a rod 17 loaded by a spring 21. A pivoted lever 27 is loaded by a spring 28, having an initial loading greater than that of spring 21, and has abutments 27<1> and 29<1> co-operable with abutments 17<1> and 30<1> respectively on the rod 17 and on a rod 30 pivotally connected to one end of a pivoted arm 33 whose other end is pivotally connected to a rod 31 connected to an extension 23 of the lever 8. An abutment 23<1> is adjustably mounted on the end of the extension 23. The position shown in Fig. 2 corresponds to maximum fuel delivery at engine starting, the abutment 30<1> holding the lever 27 in one extreme position so that it allows the rod 17 to be urged by spring 21 to its upper limit. Downward movement of the rod 9 increases the governor loading and allows the lever 27 to move clockwise under the influence of spring 28 and the abutment 271 presses the rod 17 downward against the action of spring 21 to gradually decrease the fuel supply until, as shown in Fig. 3, the abutment 23<1> contacts an element 26 secured to the lever 27. In this position the fuel supply and engine speed are both at a minimum. Further downward movement of the rod 9 causes the lever 27 to move in the opposite direction against the spring 28 and allows the rod 17 to be moved up by the spring 21 thereby increasing the fuel supply with increase of engine speed until it reaches a maximum at maximum speed. The engine may be stopped by manual operation of the rod 17 against the spring 21.

Abstract: 317,358. Gramophone Co., Ltd., and Thompsett, H. A. May 14, 1928. Magazine gramophones of the kind having a record conveyer arm 26, Fig. 2, swinging about a vertical axis 27 from a magazine x to a turntable 4 and vice versa, has means for transmitting movement from the machine motor to the conveyer arm including a member formed in two parts which move in unison during automatic movements and independently during manual operation of the conveyer arm. The conveyer arm 26 and magazine spindle 81 are raised and lowered by arms 35, 36 on a shaft 33 rocked by an arm 44 to which motion is imparted by a two-part transmitting lever, one part 49 of which has a roller 57, Fig. 5, engaging a cam 46 to move the transmitting lever in the direction for lifting the conveyer arm and the other part 48 of which has a roller 58 engaging a cam 45 to move the transmitting lever in a direction to lower the conveyer arm. The conveyer arm is counterbalanced by tension springs 41 and the two parts of the transmitting lever are connected by springs 54, 55, and are adapted to slide relatively to one another when the conveyer arm is manually raised. The conveyer arm is swung by a sliding member 62, one end of which engages a cam 63, the other end being connected by a vertically sliding pin 66 to an arm 61 extending from the, shaft 27 to the conveyer arm. A second arm 68 extending from the shaft 27 registers with holes 70, 71 according to whether the conveyer is over the magazine or over the turntable, so that the raising and lowering movement can only take place in these extreme positions. The cams 45, 46, 63 are mounted on the shaft 19 of a disc 23 geared to a wheel 5 that is automatically clutched in known manner to the turntable spindle when the needle enters the eccentric groove at the completion of the record.
