Filed: 1936-02-17
Abstract: 475,485. Pleating. TATE, F. R. (Paper Service Co.) Feb. 17, 1936, No. 4819. [Class 141] A corrugating-apparatus for producing corrugations in a travelling web in the direction of its travel comprises a set of forming members and a complementary forming member or set of forming members adapted progressively to corrugate a web passed between them, the first mentioned set of forming members or the complementary member or set of members being movable with the web, and some or all of the forming members being of flexible band, rope, wire, or like form, and means which when the apparatus is in use engage the flexible forming members directly at one or more places between the points at which the web enters into, and passes from engagement with the forming members for urging them into operative relation with the complementary forming member or members. As shown in Figs. 1 and 2, the web 10 is passed between two sets of belts 1, 2, which converge in the direction of travel of the web, and rollers 13 ... 17 engage the belts of each set to urge them between the belts of the other set to a progressively increasing extent. In a modification, one set of belts is replaced by a member having a smooth surface. In a further modification, Figs. 5 and 7, the web is passed between a circumferentially grooved cylinder 20, and a series of belts 27a ..... 27g arranged in echelon formation, the belts being caused to engage the grooves in the cylinder in a successive manner by adjustable pressure rollers 33 .. 33b. In modifications of this arrangement, the grooved cylinder is replaced by a longitudinally grooved plate which may be curved convexly, or by a series of travelling belts. In another modification, the web is passed between a series of travelling belts and a longitudinally grooved plate, the belts being arranged to come successively into operation while they run parallel with each other, after which the belts converge in the direction of travel of the web. Means are also described for crushing the corrugations formed.

Abstract: 707,873. Annealing. PARSONS CHAIN CO., Ltd. May 18, 1951 [March 2, 1950], No. 5309/50. Class 72 [Also in Groups XI and XL(b)] In the heat treatment of chain links in which individual links are heated between two hydraulically actuated electrodes the current supply is controlled by a photo-ceil or like radiation sensitive device responsive to the radiation from the heated link. As shown (Fig. 1) the chain passes vertically between electrodes 5 in a vertically mounted frame 1. The electrodes are mounted in copper electrode carrying blocks 9 which engage dovetail-fashion with fixed guides 8 so as to be capable of advancing towards the work. The electrode carrying blocks are hollow and are provided with unions to enable them to be watercooled. The projection of the electrodes from the electrode holders may be adjusted by means of abutments on the electrodes which act as nuts for hand adjusted screws 12. The electrode .movement is effected by manual control of the fluid feed to a hydraulic cylinder 18 which acts through a bellows-covered hydraulic ram 17. The reaction to the ram is provided by the crosspiece 19 at the end of the frame. To synchronise the movements of the two rams they are coupled by links 26 to a pivot !pin 30 which slides in a fixed guide 31. The photo-cell 24 is supported by a bracket 25 and projects over the heated work. The output of the cell is used to switch a pair of ignitrons which feed the primary of transformer from the secondary of which the electrodes are fed. The ignitrons are phase controlled.

Abstract: 367,181. Supply and delivery arrangements for hot-water boilers. PETRIE, D. G., 40, Guessens Court, and YOUNG, OSMOND, & YOUNG, Ltd., Unity Works, both in Welwyn Garden City, Hertfordshire. Feb. 21, 1931, No. 5525. [Class 64 (i).] In electric water heaters in which cold water admitted through an inlet 28 to a tank 17 with a heating element 18 displaces hot water through an outlet 22 provided with a syphon fitting 26 which lowers the water level sufficiently when the cold water ceases to enter to prevent dripping down the outlet 22 owing to expansion of the water during heating, an independent air passage structurally associated with the outlet, and formed for instance by a tube 23 concentric with the outlet 22, admits air to the upper portion of the tank during the syphoning action. To prevent water passing down the air passage in case of an excessive rush of water into the tank, the air outlet 25 projects into a space 35 on top of the tank 7, and bears a diaphragm 33 which seals the space 35 when the water rises. The air outlet may alternatively be provided with a valve controlled by a float in the tank or a non-return valve for the same purpose. The electric heating element 18 and the outlet 22 are mounted on a plate 19 secured between a screw threaded ferrule 20 attached to the tank 17 and a screw threaded collar 21 engaging with the ferrule. The tank 17 is carried by members 5, 6 secured to bars 2, 3 which bear the outer casing 1 of the heater. The bars 2, 3 are provided with slots 4 so that they may be screwed to a wall or other fixture.

[Classes 7 (ii) and 7 (vi)] [See also Group XXVI] A box girder casting 3 has upper openings 2 which receive cylinder liners 1 and to which transverse plates 4 and an outer longitudinal casing 5 are welded as at 8 and 9. Cylinder heads are bolted to the upper surfaces of the box girder and carry the valve-operating mechanism. The plating may also be extended outwardly to provide a support for the cam shaft bearings. The box girder 3 has a number of bridge pieces 6 with grooves or slits 7 to receive the transverse plates and the lower edges 9 of the bridges are welded to the faces of the plates 4. The plates 5 have a series of lugs 10 each of which is lap welded to the flat face of the member 3. Arranged between the plates 4 and 5 are a number of horizontal members 11 which are welded thereto and which carry centring rings 13 for positioning the bottom ends of the cylinder liners. The walls of the cooling water jackets 13 are constituted by the liner and the casings. For ease in assembling the crankshaft the frame is divided at 17 into upper and lower parts connected by bolts 18 which pass through flanges 19 and 20. The crank shaft bearings are carried by steel brackets 21 to which the casing 22 is secured by welding. In a modification the bearings have their upper halves welded to the transverse plating and the crank case is completed by a separate sump member. In a further modification, instead of transverse members forming one wall of the water jacket, separate inner divisional walls may be welded to the box girder and the centring rings.

Indicating; mounting and supporting.-In a thermometer adapted to indicate at a distance the thermometer bulb is connected to the indicator by flexible means and the indicator is pivoted to a base so that it can be tilted to any desired position. Means are provided for adjusting the indicating mechanism and pointer in relation to the scale. The bulb 1 is connected by the flexible tube 2 to a Bourdon coil 3 which operates the pointer 6 through a compensating coil 4, the bulb 1, tube 2 and coil 3 being filled with a suitable fluid. The spindle 6 on which the pointer is mounted is carried by an arbor 13 to which is secured a disc 15 having an extension 17 carrying a post 18 to which one end of the coil 3 is fixed, so that by rotating the arbor 13 the coil and pointer can be adjusted over the scale 7. The arbor 13 is mounted in a plate 10 so that a collar 14 thereon is held frictionally between this plate and a boss 33 on the casing 20. The casing is provided at its lower end with lugs 23 between which engages a lug 24 on the base member 25, the lugs being pivotally connected together by screws 26. The connecting tube 2, protected by a sheath 8, is gripped within the casing by a finger 11 forming an extension from the plate 10, and passes out between the lugs 23 and through a sleeve 42 mounted within a recess in the lug 24, a screw 43 being provided for clamping the sleeve 42. To ensure correct spacing between the pointer and scale, the casing 20 is formed with bosses 32, 33, 34 which forms seatings for the arbor 13 and plate 10, these bosses being machined with their front surfaces parallel to the scale 7. The base 25 may be mounted on a heat-insulating support 46.
