Title: Improvements in hydraulic retarding apparatus
IPC: F16F9/48
Filed: 1938-10-11
Abstract: 649,180. Dashpots. MAC TAGGART, SCOTT & CO., Ltd., MITCHELL, C. C., and PREECE, SIR G. July 11, 1939, No. 29393/38. [Class 108(iii)] Hydraulic retarding apparatus for bring- ing to rest a travelling body, e.g. the carriage of an aircraft catapult, comprises a cylinder 1 closed at its one end, and a ram 11 arranged to enter the cylinder and so shaped that as it enters, it forms a gradually decreasing orifice or orifices for the escape of liquid. The cylinder 1 and ram 11 are carried by the respective bodies 1a, 2a, the relative motion of which is to be retarded. Liquid is normally retained in the cylinder 1 by a disc 5, which consists of a thin metal or fibre plate (Figs. 3 to 5. not shown), having a central hole and peripherally-spaced radial slots. The disc 5 is enclosed in rubber which also forms an annular rib shaped to fit an annular groove 4 in the cylinder 1. The ram 11 may, instead of being of streamlined form as shown, be formed with longitudinal grooves each of progressively changing cross section. The sealing disc may be secured in position by a screw clamping ring &c. but may be omitted if the cylinder is disposed with its axis vertical. In operation the ram 11 penetrates the disc 5 when the body 2a has reached the point at which retardation is to commence. The ram and a throat portion 2 of the cylinder 1 provide a progressively diminishing escape orifice for the liquid which spouts out against surfaces on the body 2a. The latter action also assists the retardation.

Title: Single lever control unit for a reversing gear and a throttle
Inventor: MORSE JOHN FRANKLIN
IPC: B63H21/22
Filed: 1959-08-28
Abstract: 905,004. Reverse control; toothed gearing. MORSE INSTRUMENT CO. Aug. 28, 1959, No. 29455/59. Classes 80 (1) and 80 (2). A single lever control for the throttle and reversing gear of marine engines, which can be disengaged from the reversing gear to allow full range independent operation of the throttle in neutral, comprises a manual control lever 28 secured to a throttle-control shaft 19 which carries fast thereon a mutilated pinion 21 which meshes a similar pinion 24 freely rotatable on a reverse gear control-shaft 20 and clutchable thereto by a diametral pin 32 carried by the gear shaft 20 and engaged in a groove 37 in the pinion 24 when the gear shaft 20 is moved axially inwards. In this setting, during the first 45 degrees rotation from the vertical position of the control lever 28, the gear shaft 20 is turned in the appropriate direction to engage forward or reverse gears, movement of the throttle, actuated through a cable by a lever 26 fast on the shaft 19, being only slight, due to lever angle. During further rotation of the control lever 28 the gear shaft 20 is locked by surfaces 47 on the pinion 24 and the throttle is fully opened. For independent throttle movement the gear shaft 20 is pulled outwards by gripping a knob 33 to declutch the pin 32 from the pinion 24 and engage the pin in a groove 38 in the fixed casing, such movement being possible only in neutral with closed throttle and serving to lock the gear shaft 20 during independent movement of the throttle shaft 19 by the control lever 28. A ball detent 40 frictionally retains the mechanism in neutral and indicates the 45 degree positions. In Figs. 5 and 6 (not shown) the mutilated pinions are replaced by a Geneva mechanism.

IPC: C07C5/333
Filed: 1955-10-17
Abstract: Hydrocarbons of at least 2 carbon atoms are catalytically dehydrogenated by a cyclic process in which the catalyst is alternately contacted with such a hydrocarbon charge and subjected to regeneration by combustion of a carbonaceous deposit resulting from dehydrogenation of the hydrocarbon charge and the operations are carried out without interruption in a battery <PICT:0794089/IV (b)/1> of reactors operated in timed sequence, there being substantially equal periods of hydrocarbon conversion and catalyst regeneration of less than 10-minute duration in each of the reaction vessels and the sequence of operations for each reactor involves: (1) hydrocarbon dehydrogenation; (2) steam purging to free the catalyst and reaction vessel from hydrocarbon products; (3) catalyst regeneration in oxygencontaining gas; (4) evacuation and (5) reduction of oxidized catalyst in hydrogen containing gas. In a preferred embodiment, normal butane is fed into a conventional heater 3 and then through a dehydrogenation system consisting of 5 reactors as described in Specification 794,090. After passing a prequench tower 6 and a quench tower 7 which is divided by a partition 10 to form separate tables 11 and 12 the effluent gases are withdrawn overhead through line 15 and through a compression system 16 where they are subjected to a 3 or 4 stage compression to bring the pressure to 150-170 p.s.i.g.  The compressed vapours are now passed to knock-out drum 17 and then by a line 18 to an adsorber 19, the liquid products being removed by means of line 20.  In the absorber the vapours are contacted with naphtha to effect recovery of 95 per cent or more of the butene in the charge.  The rich oil from the adsorber is discharged through line 21 to a rectifier or tower stripper 22 where the adsorbed material is fractionated from the lean oil.  An overhead product consisting of C3 and C4 hydrocarbons is withdrawn through line 23 condensed in a condenser 28 and then passed to a fractionator 31.  After extraction or extractive distillation in a system 33 butadiene is removed via pipe 34.  Specification 598,650, [Group IV], also is referred to.

Abstract: 952,381. Knitting-machines. WILDT MELLOR BROMLEY Ltd. Aug.10, 1962 [Aug. 18, 1961], No. 29914/61. Heading DIC. [Also in Division G3] The needles of a knitting machine are actuated by fluid pressure. The needles 11 of a circular knitting machine are pivotable about an axis 12 into positions 1-5, of which positions 2-5 correspond respectively to miss, tuck, clear and transfer, by successive step by step movements of a yoke 17 connected by a rod 19 to a plunger 21 movable by hydraulic pressure. The rod 19 passes through a series of sleeves 22-24, each having an enlarged domed head, and reciprocable in aligned bores in the machine body. Annular chambers 32-35 are supplied with oil at successively increasing pressures. The lower end of the plunger 21 extends within a sleeve valve 25 which is moveable by a cam (not shown) into positions 1-5 to supply oil at successively increasing pressure, from annular chambers 27-30, to the underside of the plunger. Chambers 26, 31 and 36 are maintained at exhaust pressure. When the valve 25 is in the position 1 as shown the plunger, together with its needle, is maintained at its lowest level being pressed downwards by the pressure in chamber 32 acting on the upper end of the plunger. On movement of the valve to position 2 the underside of the plunger receives pressure from chamber 27 which is sufficient to raise the plunger until its upper end abuts the underside of sleeve 24 which cannot rise against the pressure in chamber 33. Movement of the valve to position 3 allows the pressure from chamber 28 to act below the plunger; this pressure is sufficient to raise the plunger and sleeve 24 against the pressure in chamber 33 to abut sleeves 24 and 23, but not to raise the sleeve 23 against the pressure in chamber 34. The operations for positions 4 and 5 of the valve is similar, the heads of the sleeves 23, 24 being arranged to enter the bores for sleeves 24 and 25 respectively. In the position 1 of the needle the latter rests on a surface 13 of a stitch length control device 14 threaded on the machine body at 15 and adjustable by rotation of a gear 16 formed with screw-driver slots for manual operation.
