Title: Improved machine for making window envelopes
IPC: B31B19/00
Filed: 1920-09-28
Abstract: 171,569. Pflanze, C. r. Sept. 28, 1920. Envelopes, making.-In a machine for making window envelopes, the mechanism for fixing the transparent patches to the blanks comprises two movable pressure-members, one of which applies the patch, which move with the blank and subject it to pressure for a comparatively long time, whereby the blanks can move continuously through the machine and adhesion of the patches is assured. The blanks are fed by means of feed-rollers 6, 8, Fig. 1, along the path shown by the arrows, and after being gummed on the flaps and around the window by means of a gum-roll 7, pass between two pressuremembers 1, 2. These members consist of flat plates pivoted at the ends of arms 3 which rotate about stationary shafts 4, the plate 1 being yieldingly connected to a supporting-plate 1<a> in order to maintain contact with the plate 2 as long as possible. Each plate is connected by a link 26 with an arm 22 which is pivoted at 23 to the carrier arms 3 and is provided with a roller 24 held by a spring in contact with a stationary cam 21. These cams, as the arms 3 rotate, turn the plates 1, 2, and keep them parallel with one another while they are in contact. The patches are cut from a roll of transparent tape 15 which is fed forward by combined severing and feeding rolls 33, 34, 35. These rolls are geared together and are kept in contact with springs 37, and the web 15 is thus held at two points by the rolls. The roll 34 is provided with serrated cutting-blades 47, Fig. 3, and the roll 35 is provided with blades 48. The edges of the blades 48 form an obtuse angle, as shown in Fig. 6, and when the web is stretched over a cutting-blade, as shown in Fig. 3, it is tightened on the cutting-edge and cut, even though the blades 47, 48 are not in contact. The roll 33 is flattened to allow the blades 47 to pass. A Geneva-stop mechanism is used to drive the rolls 33, 34, 35 intermittently, and the patch Z cut off from the web is fed forward at a high speed so that it overtakes the plate 1 and is gripped by the spring 16. An inclined plate 45 deflects the patch Z towards the spring gripper 16, which is opened by a fixed cam 19. The patch is then carried around by the movement of the arm 3 until it meets the gummed blank x, Fig. 8, and is pressed against it.

Title: Apparatus for Exercising the Body
Inventor: BRIGHTON MALCOLM
IPC: A63B21/018
Filed: 1966-01-19
Abstract: 1,179,831. Exercising apparatus. SCIENTIFIC EXERCISING EQUIPMENT Ltd. 17 April, 1967 [19 Jan., 1966; 6 April, 1966; 23 June, 1966], Nos. 2526/66; 15368/66 and 28081/66. Heading A6M. An apparatus for exercising the body comprises a frame, a flexible elongated member which is partly inside and partly outside the frame, means for exerting frictional opposition to attempted movement of the member with respect to the frame in one direction but to present no significant opposition to relative movement in the opposite direction, the means operating such that the pressure between friction surfaces necessary to provide said frictional opposition is generated by the attempted relative movement of the elongated member, and means for regulating and adjusting the value of the frictional opposition. Thus the apparatus comprises two functionally separate parts, namely a mechanism arranged to cause frictional opposition to the withdrawal of a webbing or cord (the flexible elongated member) and a mechanism arranged to draw back the webbing or cord when the withdrawal force is released. An embodiment of the invention is illustrated in Figure 1, wherein a webbing 39, which is wrapped around the outer surface of a cylindrical member 36, contacts friction surfaces 52 of the wedges 53. In operation, the webbing 39 is pulled via the bar handle 44 and the friction surfaces, contacting the webbing since the wedges bear against the rollers 63, create a frictonal resistance to movement of the webbing. The wedges are housed in a movable housing which in operation, moves until the rollers 63 fall into the recesses 64-this movement will be opposed by the tension in the spring 66 (this tension may be adjusted by screwing the part 19 in or out of the frame 10). The spring 37, affixed to the cylindrical member 36, acts to draw the webbing back into the apparatus when the handle 44 is released. Further embodiments of the invention are described and illustrated (1) wherein the friction surface bears on the inside or outside of a rotatable cylindrical body, said body being rotated by movement of an elongated member, and (2) wherein a rope or cord (the elongated member) is wrapped several times around the helically grooved external surface of a cylinder, the rotation of which is against the tension in a spring.

Title: Improvements in heating of oil or like materials
IPC: B64F1/28
Filed: 1936-10-16
Abstract: 469,708. Heating oil &c. in the circulating systems of automobiles &c. SOC. ANON. POUR TOUS APPAREILLAGES MECANIQUES. Oct. 16, 1936, No. 28172. Convention date, Oct. 25, 1935. [Class 21] The temperature of oil or like fluid which is circulated by means of a pump, e.g. on a motor vehicle, is maintained between a minimum and a maximum value by incorporating a heater which is heated by the exhaust gases of a motor which drives the pump. Oil &c. is stored in a tank 1, Fig. 1, and is heated by gases from a heater 17 circulating between the tank and a lagging 16. The oil passes through a heater 2 to the suction sides of a hand pump 3 and a driven pump 4 enclosed in a casing 5, the delivery sides of the pumps being connected to tank 1. Thermostats 11, 12, 15, Figs. 1 and 2, are supplied with electric current from a battery 18 ; one circuit, 21, comprises thermostat 11, an indicating lamp 41 contacts 31, and battery 18 ; circuits 22, 23 comprise thermostats 12 and 15 indicating lamps 42, 45, contacts 32, 35 respectively, a ball 19 and battery 18. Lamps 41, 42 and 45 and bell 19 may be on the vehicle dashboard. A hand lever 20 within reach of the driver is arranged to have three positions, " stop," "heater," and " pump " corresponding to the completion of circuits 21, 22 and 25 by closing contacts 31, 32, 35 respectively. One end of a wire 28 is wound on the stem of lever 20, the other end of which is secured to a spring 23 and to a lever 29 operating a valve 30 in heater 2. Lever 29 carries a pin 4 which engages with lost motion an eyelet 33 on a rod 34 secured to a crank lever 36 carrying a valve 37 which, under the action of a spring 38, closes a pipe 39 through which exhaust gases normally pass to a silencer 40. When conduit 39 is closed, the gases pass into heater 2 and thence, if valve 30 is open, into casing 5. The tank 1 is filled by one of the pumps through a pipe 9. Lever 20 is then moved into " pump position, closing contacts 35 to complete circuit 25, when ball 19 and lamp 45 will give a signal if the temperature of casing 5 is below its permissible minimum, in which case the engine is run free until lamp 45 is extinguished, thereafter the normal heating of the oil is effected by the setting of lever in " heater " position in which contacts 32 are closed. If the temperature of heater 2 becomes too high, thermostat 12 completes circuit 22 and actuates bell 19 andlamp 42, when the driver moves lever 20 into " stop " position when contacts 31 are con. nected. If the temperature of tank 1 falls unduly, thermostat 11 closes circuit 21 and lamp 41 is lighted to indicate that further heating is necessary. When lever 20 is in " stop " position valves 30, 37 are open as in Fig. 2. When lever 20 is in " heating position, rod 28 is pulled over by spring 23, lever 29 rotates and closes valve 30, and valve 37 so that exhaust gases enter the heater 2. When lever 20 is moved into " pump " position, rod 34 is not moved, but valve 30 is opened so that exhaust gases pass into casing 5.

Title: Improvements in or relating to cellulosic sponge material
IPC: B01J39/22
Filed: 1960-08-15
Abstract: A cellulosic sponge material is treated with a reagent capable of reacting with the hydroxyl groups of the cellulose to provide groups attached to the cellulosic structure, which groups have inherently ion-exchange properties.  An oxyacid of phosphorus, e.g. orthophosphoric acid, may be used to provide a phosphorylated cellulosic sponge material, the reaction conditions preferably being such as to provide a product having an ion-exchange capacity of 0,5-10 meq./g.  Phosphorylation may be effected by saturating cellulose with a mixture of urea and orthophosphoric acid, squeezing out most of the reagent, curing the treated cellulose in an oven at 130 DEG C. for 2-3 hours, and then washing out unreacted reagent. Other reagents which may be used include citric acid yielding citrate groups attached to the cellulose, and mixtures of strong alkali with either (a) sodium chloroacetate, to yield carboxymethyl groups, (b) aminoethylsulphuric acid, to yield aminoethyl groups, (c) 2-chlorotriethylamine hydrochloride, to yield diethylaminoethyl groups, or (d) a mixture of epichlorhydrin and triethanolamine, to yield basic groups containing tertiary nitrogen.  The cellulosic sponge material may be in block or sheet form and may contain scrim or fibrous reinforcing material.  It may be prepared by rolling out a crystal paste of viscose and regenerating the viscose by conventional means.  Materials so made have a high ion-exchange capacity and good structural rigidity, and liquids flow through such materials rapidly.ALSO:A cellulosic sponge material is treated with a reagent capable of reacting with the hydroxyl groups of the cellulose to provide groups attached to the cellulosic structure, which groups have inherently ion-exchange properties.

Title: Improvements in or relating to cooling arrangements for semiconductor rectifiers
Inventor: BAYLEY JAMES
Filed: 1962-07-24
Abstract: 979,262. Cooling system for semi-conductor rectifiers. GENERAL ELECTRIC CO. Ltd. July 19, 1963 [July 24, 1962], No. 28422/62. Heading F4U. [Also in Division H1] A heat sink for a plurality of semi - conductor rectifiers comprises a container housing a closed circuit in which fluid can circulate, the container having a wall portion in contact with part of the length of the closed circuit which is adapted to carry the rectifiers externally of the container, and a part of the closed circuit not in contact with the wall portion having cooling means associated therewith, the arrangement being such that when the rectifiers are in an operating condition, fluid is circulated in the closed circuit by a thermosyphon action. In the Figure, semi-conductor rectifiers 3 are mounted on one side of a ribbed metal cooling member 1, from the other side of which extend ribs 2. The member constitutes an electrical supply bus-bar for the rectifiers 3, an end portion being connected to an electrical supply. Strips 6 and 8 are welded to the outer ribs 2 to form two ducts 7 and 9. An air duct 10 within a pipe 11 runs along duct 9 whilst the ribs project into duct 7. The strip 6 does not extend the full length of the ducts which have their ends interconnected. A fluid is heated by the ribs in duct 7 and is cooled in duct 9 by air which surrounds said duct and by air within the tube 11. Fixing lugs 15 permit the mounting of the sink on a supporting structure. A radiator may be placed in the fluid circuit such as in one of the connections between ducts, to replace the air duct 10 and permit cooling of the fluid. The rectifiers will all be at the same potential, and if a number of groups of rectifiers are arranged in bridge or like connections, the sink units will have to be insulated from each other and from earth.
