Title: Improvements in or relating to the manufacture of wire fabric and particularly chainlink fabric
IPC: B21F27/14
Filed: 1951-07-19
Abstract: 703,021. Making wire fabric. RYLANDS BROS., Ltd., and FAULKNER, D. S. July 15, 1952 [July 19, 1951], No. 17119/51. Classes 83 (2) and 83 (4) Apparatus for dividing a length of chain link or like fabric into two or more widths, comprises means for traversing the fabric step-bystep, and means for cutting the fabric and knuckling over the wire ends along the cut edges during halts in the movement of the fabric and means for synchronizing the operation of the cutting and knuckling means with the movement of the fabric. The apparatus may be combined with a machine for weaving chain link fabric, Fig. 1, and comprises a base plate 14, adjustably positioned laterally of the fabric, and carrying a cutting unit 15 and knuckling units 16, 17. The cutting unit comprises opposed reciprocating cutters 22, 24, Figs. 3 and 4, mounted on slides in a vertical slideway 18 and actuated through toggles 27 from a pneumatic piston 25. Each knuckling device, Fig. 5, comprises male and female tools 28, 29 carried on a vertically movable slide 30. Racks 39, 40 on a crosshead 37 engage with pinions 41, 42 engaging with rack teeth 43, 44 on the tools. A piston rod 36 abuts the cross head 37 and in operation raises the crosshead and slide so that the tools penetrate the mesh. Further movement of the slide 30 is halted by stops 45 on the guide rods 32, and the crosshead 37 continues to move against a spring 38; causing the knuckling tools to move together to effect a knuckling operation. The sequence of operations is timed by the actuation of valves 47-49, controlling the supply of pressure air to the actuating pistons, by a cam shaft 60 driven in synchronism with operation of the weaving machine. In a modification, Fig. 8 (not shown) the device is arranged to cut and knuckle chain link fabric drawn from a roll. The Provisional Specification states that the cutting and knuckling devices may be operated by a photo-electric cell and light beam.

IPC: F02D1/00
Filed: 1968-04-11
Abstract: 1,231,010. Damped spring units. GANZMAVAG MOZDONY-VAGON-ES GEPGYAR. 11 April, 1968 [12 April, 1967], No. 17517/68. Heading F2S. [Also in Division G3] A piston 4 divides an associated liquid-filled cylinder into two chambers 12, 13 between which there are two throttled flow paths, and a pair of springs 2, 3 are connected one to each side of the piston. The resulting damped spring- unit controls a rotating-pendulum type enginespeed governor. The governor, when connected as shown to the spring 2, can fluctuate in speed and thereby compress and extend the spring 2 rapidly without substantially affecting the position of piston 4 in its cylinder, so that engine speed changes not dependent on engine load changes are effectively resisted by the spring 2 alone. If however the engine load changes, the virtual equilibrium of the piston 4 will be disturbed and there will be a gradual and smooth change in the position of the governor pendulum weights 1, controlled by the springs 2, 3 and the dashpot action of the piston. The throttled flow paths between chambers 12 and 13 include a constriction 5 in a passage 11 leading round or (as shown) through the piston. This passage is by-passed by a second passage 17, Fig. 3, containing a valve element 10 which opens the passage 17 whenever the piston moves substantially in response to a large change in engine speed. In Fig. 3 the by-pass passage is open for both large reductions and large increases of engine speed, and is controlled in both directions of change by the same valve element 10, the construction of which is depicted in Fig. 4 (not shown), Fig. 3 being merely diagrammatic. Fig. 1 (not shown) depicts an embodiment in which there are two by-passes each controlled by its own valve, one opening on speed increase and the other on speed decrease and Fig. 2 (not shown) depicts the Fig. 1 embodiment modified by the omission of one of these by-passes; in both Fig. 1 and Fig. 2 all the flow control passages are outside the cylinder, the piston being unapertured. In Fig. 5 a one-way acting by-pass is provided by a valve element 8 which itself contains the flow-throttling constriction 5.

Title: A process for separating acetaldehyde by distillation from its aqueous solution
IPC: C07C/
Filed: 1963-05-03
Abstract: In a process for separating acetaldehyde from its aqueous solution by fractionation in a distillation column, the solution is preheated in a heat-exchanger, under such a pressure that there is no substantial evolution of vapour, to a temperature that is above the boiling point of the solution under the operational conditions in the column, and the solution is then passed through an expansion valve into the column.  Acetaldehyde vapours pass out of the head of the column to a condenser.  In an example, a 20% solution of acetaldehyde solution is preheated from 10-90  DEG C. under a pressure of 3 atm. in the heat-exchanger, and then expanded into the column.  Superheated steam is introduced into the lower section of the column, which is operated at a pressure of 2 atm. absolute.  The water withdrawn from the sump of the column has a temperature of 120  DEG C., and is used to preheat the aqueous acetaldehyde in the heat-exchanger.  The aqueous acetaldehyde solution may contain acetylene and crotonaldehyde.
