Title: Hydrogenation process
Inventor: CANDLIN JOHN PATON
IPC: C07C5/09
Filed: 1966-08-24
Abstract: 1,141,847. Selective hydrogenation. IMPERIAL CHEMICAL INDUSTRIES Ltd. 17 Aug., 1967 [24 Aug., 1966; 8 Sept., 1966], Nos. 37984/66 and 40207/66. Heading C5E. [Also in Division Bi] Selective homogenous hydrogenation of hydrocarbons containing two or more sites of unsaturation is effected by contact with hydrogen in the presence of a solution containing a soluble divalent ruthenium compound. Specified selective hydrogenation reactions are (1) hydrogenation of terminal acetylenic bonds in preference to terminal olefinic bonds e.g. hexene-1 before octene-1; (2) hydrogenation of terminal olefinic bonds in preference to cyclic olefinic bonds e.g. hexene-1 before cyclohexene; (3) hydrogenation of terminal olefinic bonds in preference to internal, non-cyclic, olefinic bonds e.g. pentene-1 before pentene-2; (4) hydrogenation of conjugated dienes in preference to straight chain and cyclic olefines e.g. cis- and trans-pentadienes before cyclopentene. In examples (1) hexene is hydrogenated in the presence of cyclohexene; (2) hexene in the presence of octene-1; (3) 4-vinyl cyclohexene is converted rapidly to ethyl cyclohexene (as opposed to vinyl cyclohexane; and (8) pentadienes are hydrogenated in the presence of pentenes-1, -2 and cyclopentene.

Title: Tanning agents prepared from ammonium bisulphite and phenol-formaldehyde condensates
Inventor: KOMAREK ERNST
IPC: C14C3/20
Filed: 1958-11-26
Abstract: 864,079. Tanning leather. FARBENFABRIKEN BAYER A.G. Nov. 26, 1958, No. 38199/58. Class 76. [Also in Group IV (a)] Synthetic tanning agents, which are practically free from ash and have a purity number greater than 90, are prepared by reacting a phenol or a polyphenol with a molar excess of formaldehyde in the presence of a small amount of an alkali metal hydroxide, neutralizing the mixture and, after separation of the low molecular weight salt-containing resin, further reacting it with ammonium bisulphite. Phenols and polyphenols specified are phenol itself, o-, m- and p-cresols, o-, m- and p-chlorophenols; dihydroxydiphenylmethane, dihydroxydiphenyl-dimethylmethane, dihydroxydiphenylsulphone and the corresponding dihydroxydiphenyl compounds obtained from the other above-specified phenols; empyreumatic oil; and low molecular weight novolacs. The ammonium bisulphite is preferably formed during the reaction by first adding ammonia and then introducing gaseous sulphur dioxide. The tanning agents can be used not only for the manufacture of white leather but also as pretannins, re-tannins and exchange tannins; they are especially useful for continuous use in the pit systems. In Example 2, a cow-hide, limed, split to 3 mm., delimed and mordanted in the usual manner, is drum tanned with a tannin mixture consisting of 250% water, 7% pure tannin Quebracho sulph., 7% pure tannin Mimosa sulph. and 7% pure tannin prepared by reacting ammonium bisulphite with a low molecular weight novolac which has been further reacted with formaldehyde in the presence of sodium hydroxide; the leather is then fatliquored and finished in the usual manner. Another example describes the pre-tanning of a cow-hide with a tanning agent of the invention followed by treatment with vegetable tanning agents. Other examples describe the treatment of goat-hides and cow-necks.

Title: Improvements in straight bar rib knitting machines
Inventor: START ERNEST
IPC: D04B11/00
Filed: 1956-12-14
Abstract: 840,978. Knitting-machines. COTTON Ltd., W. Nov. 19, 1957 [Dec. 14, 1956], No. 38256/56. Class 74 (2). The slide bar 6 for knocking over the loops on the rib needles of a straight-bar rib machine has its forward edge rearwardly slanted as at 6a so as to cam the knocked-over loops 50L downwardly to a position clear of the rib needles when they re-advance preparatory to the next course. The knock-over bits 4 may also be operated to assist the action of the edge 6a and enable re-commencement of knitting automatically after a press-off, or commencement of knitting without the aid of run-on fabric. The sequence of knitting involves the drawing and sinking of a yarn about the frame or plain needles 1 whereafter the frame or plain needles draw loops and knock over their old loops prior to the machine or rib needles 5 receiving the yarn. The withdrawal of the sinkers subsequently causes their loops to pass on to the machine or rib needles after which the machine needles are operated to knit the yarn. The slide bar is tricked, as shown in Fig. 3, to accommodate the machine or rib needles and the front edge is recessed as at 6f to correspond with the needle tricks. The bottom 6b of the front edge is curved to assist the knocking over of the rib loops.

IPC: G01F1/50
Filed: 1960-11-08
Abstract: 964,515. Mass flowmeters. ROTRON CONTROLS CORPORATION. Nov. 8, 1960, NO. 38359/60. Heading G1N. In a Mass flowmeter the output of an orifice or Venturi type flowmeter is combined with the output of a rotary vane type flowmeter in order to measure the density and the mass rate of flow of a fluid. In Fig. 1 the differential pressure in a Venturi flowmeter 1 is measured and an output voltage V1 alpha Jv<2> (where J is density and v is the velocity of flow) is fed to the ratiometer 4. A second input to the ratiometer is obtained from a generator 3<11> driven by the vane type flowmeter 3 so as to obtain a voltage V2 alpha v<2> = (velocity of flow)<2>. Ratiometer 4 divides V1 by V2 and so pointer 4<1> and shaft 6<1> are positioned in accordance with the density J of the fluid. In order to obtain the mass flow the rotations of the rotor of flowmeter 3 are transmitted via a synchronous torque amplifier 7 to one input 6<11> of a multiplier 6, to the other input of which is fed the density information on shaft 6<1>, the output shaft 9 then rotates at a speed proportional to the mass rate of flow and the counter 10 indicates total flow.

Title: Fluid Pressure Control Systems
IPC: G05D16/18
Filed: 1967-08-22
Abstract: 1,157,943. Fluid-pressure servomotor systems. PARKER-HANNIFIN CORP. Aug. 22, 1967, No. 38599/67. Heading G3P. A fluid system comprises a tank 2, Fig. 1, a pump 4 having an intake port 3 in communication with liquid in the tank and a discharge port for delivery of liquid through a conduit 5, 17, valve means 6 operative in response to variation in liquid pressure adjacent the downstream end of the conduit to vary the flow through the conduit, and pump anti-cavitation means 27, 28 operative in response to a decrease of liquid in the tank to a predetermined minimum level to conduct liquid pressure adjacent the upstream end of the conduit to operate the valve means to reduce or discontinue the flow of liquid from the downstream end of the conduit. In the preferred embodiment, the conduit supplies a fuel delivery nozzle 1 and the valve 6 has a main closure 7 controlled by a spring-loaded pilot valve 11 subjected to downstream pressure through a conduit 18. When the liquid in the tank falls to a predetermined level, fluid from a jet nozzle 27 enters a receiver 28 to operate a shuttle valve 24 and close both the main and pilot closures 7, 11. In a modified arrangement, the valve means are incorporated in a by-pass line between the delivery conduit and the tank. Fig. 4 shows a further embodiment in which a by-pass valve 6<SP>1</SP> controlled by the pressure at a point 58 in the delivery conduit and by the level in the tank is provided in addition to a valve 57<SP>1</SP> controlled by a valve 70 which requires a lever 71 to be held in an actuated position to conduct air under pressure to the pilot valve 60. If the lever 71 is released, both pilot valves are closed to shut off flow through the delivery line and open the by-pass. Only the by-pass valve 6<SP>1</SP> is operated, however, in response to a fall in liquid level causing an actuator 81 to shift a valve 74 and connect a chamber 19 to atmosphere. The by-pass valve may be omitted and the valve in the delivery conduit made responsive to liquid level and downstream pressure as well as to operation of the valve 70.

Title: Improvements in the manufacture of thin magnetic anisotropic layers
IPC: H01F10/20
Filed: 1960-11-15
Abstract: A method of manufacturing a thin ferrimagnetic magnetically anisotropic layer having a thickness in the range of several hundred <\>A to several thousand <\>A and a composition (Me1xy CoxFey) O.Fe2O3 where Me represents one or more divalent metals and 0.001 x 0.05 and 0.05 y 0.15 includes the step of cooling the layer after its formation, in a magnetic field.  The formation may be by (a) forming an initial metallic layer and oxidizing this, or (b) by forming a ferrite directly.  In the first a metal layer may be formed by high vacuum evaporation, cathodic sputtering or electrolytic deposition. In one example a NiFeCo alloy is evaporated from an alumina or magnesia crucible on to a carrier of glass or alumina in a pressure less than 10-6 mm. Hg., to form a layer. This layer is carefully oxidized at a temperature between 600 and 1000  DEG C. by varying the O2 content of a N2/O2 atmosphere until a ferrite structure is formed. The O2 supply is suppressed and the layer cooled in a magnetic field. The initial metal layer may be formed by evaporating the component metals individually. Alternatively it may be formed by sputtering in an inert gas, N2 or H2 at a pressure of 10-1-10-2 mm. Hg.  A single (alloy) cathode or individual (metal) cathodes may be used.  In the direct method a suitable alloy is sputtered in an oxidizing atmosphere on to a carrier at 800  DEG C. to form the ferrite layer. Alternatively the ferrite may be evaporated from a crucible at 1400-1600  DEG C., or produced by electric current through adjacent ferrite rod tips.  The symbol Me may comprise the elements or combinations Ni, Mn, Mg, Ni Zn, Mn Zn, Cu, Mg, Zn, Ni Mn, Ni Cd, Mn Mg.

Title: Improvements in or relating to the production of combustible gas
Inventor: MACCORMAC MICHAEL
IPC: C10K3/00
Filed: 1961-11-07
Abstract: Coal gas e.g. coke oven gas, is reformed by mixing with oxygen to produce a mixture which contains barely sufficient free oxygen to propagate a flame and bringing this main mixture into direct contact with a pilot flame to initiate combustion of the main mixture to provide a reformed coal gas which is suitable after cooling and purification as a diluent gas. The pilot flame may be a diffusion flame maintained by the confluence of the main mixture and a limited amount of oxygen.  As shown a mixture of air and gas entering at 15 passes through a flame trap 13 into a combustion chamber 26. Immediately above and surrounding the flame trap is the float ring or manifold for the pilot burners 18, which are supplied with a pilot air and gas stream bled off from the main stream at 14 and mixed with additional air entering at 16.  The pilot burners consist of jets partly recessed in cylindrical hollows within a refractory ring 19 which rests on the pilot float 20.  Means <PICT:0961341/C4-C5/1> for igniting the flame in the combustion chamber are provided in side arm 27, which contains a movable pipe 21 and a sparking plug 23.  A gas and air mixture is passed through pipe 21, ignited by the sparking plug 23, and the flame formed is pushed into chamber 26 by pushing forward pipe 21.  Steam may be included to prevent the formation of soot.  Air is the main source of oxygen.

Title: Improvements in or relating to roll film cameras
IPC: G03B19/04
Filed: 1957-12-23
Abstract: 840,280. Photographic cameras. KODAK Ltd. Dec. 23, 1957 [Dec. 26, 1956], No. 39964/57. Class 98(1) In a roll-film camera, the locking 'action of a device for locking the film-wind mechanism is. suspended during the winding of a pre-determined leader length of film by holding means which are responsive to the increasing diameter of film wound on the take-up drum. and allow the device to become effective to control the filmwind mechanism when the pre-determined length has been wound. As shown, a multi-armed film wind locking lever 22 is turned anticlockwise manually by arm 24 about pivot 122 and against spring 23 during the re-winding of imposed film from the take-up drum into cassette 9. On winding on a new film leader, the initial movement of shoe 32 riding on the take-up roll 10 disengages a lock between arm 133 and lug 39 of lever 22 and the extent of the movement and hence the length of the leader is determined by the depth of engagement of lug 39 and shoulder 38. This can be varied by bending tongue 37 outwards or inwards. When lever 22 is freed, lug 26 rides on the periphery of disc 18 which is driven by the film through sprocket 16, and almost immediately enters a notch 19 thus bring- ing pawl 27 resiliently into engagement with ratchet wheel 14 to lock the film wind operated by handle 13. As shutter trigger 42 is depressed to make the exposure, incline 47 turns arm 48 of lever 22 to disengage lug 26 from notch 19. Arm 48 thereafter snaps back into shallow recess 49 and holds trigger 42 down. On winding the film on again a tooth 21 engages arm 40 thus removing arm 48 from recess 49 and allowing the shutter trigger 42 to rise. The downward movement of trigger 42 turns blade 51 and disc 53 from the position shown in Fig. 2 to make the exposure and, the return movement brings the blade and disc back without uncovering the exposure aperture 58. Blade 51 is latched by engagement with lug 52 of disc 53 and the latch is not released until lug 46 strikes ear 55 and spring 50 has been tensioned (by the downward movement of trigger 42) to drive blade 51 clockwise. The motion of blade 51 flexes hair-pin spring 56 which thus drives disc 53 anticlockwise to end the exposure. On the return movement blade 51 is carried by lug 61 to tension and release hair-pin spring 56 and so allow disc 53 to be turned clockwise into its original position. Shoe 32 operates exposure counter 33, 34.
