Title: Improvements in felting machines
IPC: D04H17/00
Filed: 1952-12-19
Abstract: 726,680. Felt. WAHL, sen., N., and WAHL, jun., N. Dec. 19, 1952 [Oct. 6, 1952], No. 32294/52. Class 42 (2). A felting machine has a jogger platen and a plurality of spindles arranged vertically of the platen, the spindles being axially adjustable during the jogging operation to vary the pressure applied by the platen to the material to be felted. As shown, Fig. 1, the jogger platen 3 is supported, through bushes 11, on collars 9 secured to threaded spindles 8, bushes 11 having a large bore to allow for the jogging movement of platen 3. Each spindle 8 can be raised and lowered, by rotation of a threaded worm wheel 7, to raise and lower platen 3 relative to the felting work 10 and to apply during the jogging operation downward pressure to platen 3, additional to the weight thereof, through a disc 12 and spring 13. A pointer 15 indicates on a scale 14 the total applied pressure. A cut-off switch 17 is operated by an adjustable abutment 16 on spindle 8 when a desired maximum applied pressure is reached. To avoid air suction and compression effects, the raising and lowering mechanism may be arranged to operate more slowly when platen 3 is in a zone immediately above material 10 than at other times. The loading and unloading of the springs may be effected hydraulically, pneumatically or electro-magnetically, instead of mechanically. In another embodiment, Fig. 2, downward pressure is applied to platen 3, through a plate 22 and ball 21, by a piston 25 subjected to variable fluid pressure in a cylinder 26. Piston 25 also acts to raise and lower the platen. In a further embodiment the jogging platen rests at the corners, through balls, on supporting spindles which can be raised or lowered during the jogging operation to vary the proportion of the weight of the platen which is supported by the felting material.

Title: Improvements relating to torque converters combined with gearings
Inventor: SIDNEY RONALD ALEC
IPC: F16H47/08
Filed: 1952-12-22
Abstract: 734,533. Variable speed gearing. STANDARD MOTOR CO., Ltd. Nov. 24, 1953 [Dec. 22, 1952], No. 32397/52. Class 80 (2). [Also in Group XXXIV] In variable speed gearing wherein a three-element hydraulic torque-converter (not shown) is combined with toothed epicyclic gearing which gives a low forward drive and a reverse drive, the two drives are engaged by respective brakes 27, 28, and a direct drive between the torque - converter shaft 17 and the output shaft 14 is engaged by a cone clutch 31 when the brakes are released, the clutch being actuated by an annular hydraulic plunger 39 whose cylinder 37 is part of the non-slidable element 30 of the clutch. Hydraulic pressure is generated by a pump (not shown) connected to the outer element of the torque converter. The epicyclic gearing comprises a driving sun 18 on shaft 17, a driven carrier 20 on shaft 14, intermeshing planetary pairs 22, 23, a free sun 25 and a free annulus 24, one or other of the two latter members being held by the brakes 27, 28 to provide a reaction for the forward and reverse drives respectively. The slidable clutch element 31 is splined on the shaft 17 and is lightly spring- loaded to the off position. A keyway in the plunger 39 is engaged by a peg 41 on a flange of the back plate of cylinder 37. Hydraulic pressure is supplied through a port 44 to the cylinder 37 to clutch sun 25 to shaft 17, i.e. to sun 18, and so provide a direct drive. To entrain the epicyclic gearing, the cylinder 37 is exhausted through port 44 and the clutch is freed by means of a low hydraulic pressure continuously applied through port 47 to the element 31, the area of element 31 being greater than that of the annular plunger 39. As soon as the element 31 has been released the low pressure acts on the plunger 39 to hold it inoperative, a bleed hole 48 being provided. The fluid providing the said low pressure comprises lubricant which is continuously supplied along bore 46 to the bearings of the gearing. Preferably, the brakes are hydraulically operated, and a tandem hydraulic mechanism is shown for applying the reverse brake band 28, Fig. 3, through a strut 50, the mechanism comprising a first plunger 51 reacting on a stationary abutment 52, and a second plunger 53 reacting on an end wall 54. Fluid is supplied to the back of the plunger 51 along a passage 56, and is fed to the back of plunger 53 through a bore 57 in the latter. The brake band 27 is applied by a single hydraulic mechanism. A compound control valve such as that disclosed in Specification 734,534 may be used to engage the clutch and brakes as required, this particular valve supplying fluid at a higher pressure for the brakes than for the clutch.

Filed: 1957-10-18
Abstract: 846,152. Distilling zinc. NATIONAL SMELTING CO. Ltd. Sept. 4, 1958 [Oct. 18, 1957], No. 32639/57. Class 82(1) Zinc is separated from zinc of low lead content by distillation under vacuum at a temperature of 450-500‹ C. The zinc of low lead content may be obtained by distillation from zinc-containing lead under vacuum, the vapours being condensed in a circulating stream of molten zinc at a lower temperature, zinc being simultaneously evaporated from this circulating stream and condensed at a still lower temperature. In the apparatus shown m Fig. 1 zinc-containing lead enters by pipe 2 to fill an annular well 3 and overflows lip 7 to flow downwards over the inner surface of wall 5. Zinc vapour contaminated with lead passes to an annular system of shelves comprising outward facing shelves 13 and inward facing shelves 12 over which molten zinc flows from annular trough 17. The vapours condense on the shelves 13 and substantially pure zinc vapour is simultaneously formed by evaporation from shelves 12 to be condensed on a condenser 21 which is cooled by cooling coils 21a to form a solid deposit of zinc 20. At a certain thickness of the deposit 20 the zinc vapour condenses as liquid and drips into tube 25 from which it is withdrawn. The leadcontaining zinc flowing over shelves 12, 13 is collected in annular trough 14a, passes to vessel 14 in which zinc-saturated lead separates and is removed by overflow 18, the remaining zinc being pumped through tube 16 to trough 17. Vacuum is maintained via pipe 24, a cold trap 23 and the interior of condenser 21 in which a radiant heater 22 prevents the formation of accretions of solid zinc.

Title: Process for the production of dialdehydes or conversion products thereof
IPC: C07C45/50
Filed: 1952-12-29
Abstract: Dialdehydes and diols are produced by subjecting dicyclopentadiene or a similar cyclic diolefin to the addition of carbon monoxide and hydrogen under oxo conditions but pressures below 300 atmospheres in the presence of a diluent, a polymerization inhibitor, a stabilizer, and cobalt, or a cobalt compound capable of yielding cobalt hydrocarbonyl, and in presence of metallic cobalt or iron followed by catalytic hydrogenation. When metallic cobalt is used as catalyst, it may function also as polymerization inhibitor.  In examples, dicyclopentadiene is caused to react with water-gas in benzene as diluent, and with hydroquinone as stabilizer, with ferrum reductum or metallic cobalt as polymerization inhibitor, and with aqueous cobalt sulphate and magnesium sulphate, or a reduced cobalt/magnesia kieselguhr, as catalyst, to give the dialdehyde with some monoaldehyde and diol and other products.  The reaction mixture may be catalytically hydrogenated without or with isolation to give mixtures containing monols, diols and resinous products.
