Title: A device for use in cutting tubular fabric
IPC: D06H7/08
Filed: 1945-12-22
Abstract: 641,463. Cutting fabrics. ROBOTTOM, F. H. Dec. 22, 1945, No. 34880. [Class 31 (i)] A device for use in cutting tubular fabrics which is especially applicable for producing stockings such as are described in Specification 640,342 is constructed of a flat board 3 having rounded edges over which the fabric tube is placed and held in position by upper and lower clamps 9, 10 carried by levers 5, 6 normally pressed together by a spring 19. The front edges of the board 3 are chamfered to form guides for a knife by means of which triangular pieces are cut from the toe end of the stocking. The clamps can be opened by depression of a treadle connected by a chain 17 to a sliding member 14 fitted with rollers 15 which engage the bent ends of the clamping levers 5, 6 and force the clamps apart as the slide moves towards the pivots 7, 8 of the clamps. The board 3 is supported by an upright 2 and an inclined strut 22, and a stop-plate 21 prevents the tube from being moved to a position in which it can foul the member 14, while being drawn over the board 3.

Title: Automatic voltage regulators
Inventor: DARBY KENNETH
IPC: B03C3/68
Filed: 1956-11-15
Abstract: 860,162. Automatic control systems for electrostatic precipitators. LODGE-COTTRELL Ltd. Dec. 6, 1957 [Nov. 15, 1956], No. 34999/56. Addition to 832,342. Class 38 (4). The electrode voltage of an electrostatic precipitator is maintained at its maximum value (subject to a supply current limiter) by repeatedly raising the supply voltage until a " raise increment results in a drop in electrode voltage, then lowerirg the supply voltage several increments and trying again. The precipitator P is supplied from a high voltage rectifier RE from an E.H.T. transformer T2 in turn supplied from an auto-transformer T1 which is adjustable by a reversible servomotor M1. A portion of the electrode voltage is tapped off a potential divider R8, R9 and applied to an unspecified device I which is stated to translate a change in its input voltage into an alternating output voltage, the phase of which may be reversed according to whether the change in input voltage is an increase or a decrease. This A.C. output voltage is applied to the grid of a thyratron V in addition to an A.C. bias 180 degrees out of phase with the anode voltage (obtained from a centre-tapped winding on the transformer T3) and in one embodiment the signals are so phased that the thyratron V is fired in response to a decrease in voltage input to the device I. The anode circuit of the thyratron V includes a relay S1 and the contacts TS3 of an unspecified timer. The times also has contacts TS1 which close before contacts TS3 so as to energize the motor M1 over the "raise " contacts of a relay S3 for a period during which the supply voltage is raised. As a result of this rise the precipitator voltage will either increase, if the precipitator is below optimum condition, in which case the thyratron V is not fired and the supply voltage is again raised; or the precipitator voltage will decrease because the optimum condition has been passed. In this case the thyratron V will be fired as soon as contacts TS3 close, thereby energizing relay S1 so that when contacts TS2 close the relay S3 changes over to energize motor M1 to reduce the supply voltage for a period determined by the setting of timer contacts TS2. The supply voltage is then again raised by contacts TS1 and the cycle continues. Supply current limiting is effected by a current-sensitive relay S2 which changes over relay S3 to the " lower " position if a set value of supply current is exceeded. As an alternative, the thyratron V may be made to fire when the precipitator voltage increases, in which case the supply voltage is raised until the precipitator voltage stops rising.

Title: Improved process of and apparatus for use in effecting emulsification
IPC: B01F5/02
Filed: 1932-12-09
Abstract: <PICT:0407153/III/1> <PICT:0407153/III/2> Emulsions, for example aqueous tar emulsions, are prepared by repeatedly ejecting a mixture of the liquid ingredients through nozzles or jets immersed in liquid against baffles opposite to the jets.  The liquid may be emulsifying medium, the process then being a batch process, or may be a ready prepared emulsion, in which case mixed ingredients are continuously supplied and completed emulsion continuously withdrawn.  As applied to tar emulsions a tank 1, Fig. 1, is connected by draw-off pipes 2, 4, at different levels, to the suction side of a pump 3 itself connected by a pipe 5 with a series of nozzles 13.  Emulsifying medium, which may be a solution of sodium or ammonium oleate or resinate, alkali casein, a sulphonic or naphthenic acid sodium salt, or a colloidal earth suspension, is heated in tank 1 by a steam coil 23 and circulated by the pump through the nozzles 13 whilst tar is delivered from a hopper 20 through a pipe 22 on the suction side of the pump.  The emulsion once formed is employed as the nucleus for continuous production, tar and emulsifying medium being supplied continuously to the hopper 20 from steam-heated constant level tanks, 28, 29, delivering to orifice flow meters 26, 27, or volumetric pumps or adjustable weirs.  Completed emulsion is continuously withdrawn through pipe 25.  A bye-pass pipe 18 controls the delivery pressure of the pump.  The nozzles 13 are provided on opposite sides of headers 11, 12, Fig. 2, supplied from pipe 5 by pipes 7 ... 10; baffle plates 14 ... 17 are secured opposite each row of nozzles.

Title: Improvements in irradiation of nylon
IPC: B29C71/04
Filed: 1957-11-18
Abstract: Nylon is irradiated with high energy ionizing irradiation having energy equivalent to at least 5 X 104 electron volts to a dose of 1 X 106-1 X 108 rep. at from 60 DEG  C. to the melting-point whereby the susceptibility to oxidation and elongation are reduced and cross-linkage is increased without reduction of the tensile strength. The irradiation may, alternatively, take place at a temperature below 100 DEG  C. and the irradiated nylon then be heated at a temperature from above that at which it was irradiated to the melting-point ("annealing"). The preferred temperature during irradiation is 75 DEG to 225 DEG  C.; similar temperatures above 100 DEG  C. are preferably used for the annealing.  The annealing should be conducted immediately after irradiation unless the material is retained in an inert atmosphere, to avoid oxidation of free radicals trapped in the polymer.  The preferred radiations are electrons, e.g. from an accelerator or betatron preferably having an energy from 50,000 to 20,000,000 electron volts but other sources of high energy ionizing radiation may be used, e.g. g -rays (obtained from cobalt 60, "burnt" uranium slugs, fission by-products, separated isotopes such as caesium 137 or gaseous fission products liberated from atomic reactions) fast neutrons, slow neutrons, mixed neutron and g -radiation from atomic reactors, X-rays, protons, deuterons, a -particles and fission fragments, such as are available from cyclotrons.  Materials specifically referred to are the products of reaction of adipic acid and hexamethylene diamine, from sebacic acid and hexamethylene diamine, from butyrolactam, caprolactam and o -amino-undecanoic acid.  Specification 767,203 is referred to.
