Abstract: 1,192,432. Making levers; angular bending. INDUSTRIAL RESEARCH PRODUCTS Inc. 16 May, 1967 [17 May, 1966], No. 22567/67. Headings B3A and B3E. [Also in Division H4] A lever used in a piezoelectric transducer (see Division H4) to connect a diaphragm to a piezoelectric element is constructed from flat sheet material. At one end of the sheet a diaphragm tab 108 is formed and at the other end an element tab 102 is formed. A pivot tab 124 is cut out of arm 98 and the tabs are bent to the positions shown in Fig. 10. Before bending slots 112, 118, 126 are cut in the sheet and the remaining parts of the sheet width are etched or coined so that a minimum amount of material remains at the junction of the tabs and arm 98. Stiffeners 104 and 106 are provided at the sides of the lever and the bending line is grooved. After bending the pivot tab is welded or stuck to its support and the finger 110 is positioned in an aperture in the diaphragm and secured by adhesive. The element tab 102 is secured to the free end of the piezoelectric element.

Title: Improvements in or relating to vacuum flasks
Inventor: BATESON HERBERT MARSHALL
IPC: A47J41/02
Filed: 1951-10-01
Abstract: Before incorporation in the outer glass vessel, the inner glass vessel of a vacuum or Dewar flask receives on its outer surface a coating of condensed aluminium by being disposed in an evacuated chamber in which aluminium is heated and vaporized.  The inner vessel is rotated during treatment and is first cleaned by heating and electric discharge as the chamber is evacuated.  Aluminium is heated in the chamber in a crucible or by heating a tungsten filament about which an aluminium wire is wrapped.  The coating on the glass is heated to 200 DEG C. to provide an oxidized, scratch-resistant surface.  The finished flask may have an aluminium coating on the inner vessel only.

Abstract: 1,101,009. Physical training equipment. P.ELIA and K. ELIA. 17 May, 1966 [28 May, 1965], No. 22825/65. Heading A6M. The physical training equipment comprises a trolley fitted with a seat, movable on rails, with a resilient means such as springs contained within the trolley, said resilient means tensionable by a cable operated by the user thus simulating a rowing action. The apparatus is depicted in Figure 1 and the arrangement of cables and pulleys is shown in Figure 2. The shaft 10, mounted in and between the fore- and-aft slots 9, is fitted with a toothed pinion 11 running in mesh with a rack 12 fixed to the wall of the frame 5, thus ensuring that the shaft 10 will not skew in the slots. The springs 13 draw the shaft 10 rearwards towards the axle 6b, and the shaft can only be drawn forward if a sufficiently large force is applied to the movable shaft 10 through the cables running over the pulleys 22. Thus in operation, the seated user with feet on rests 20, hauls the cables thus drawing the shaft 10 forward. This latter movement is opposed by the springs 13. At the same time, leg action against the foot rest, causes the trolley to move backwards. These operations simulate a sculling action.

Fig. shows a compressor or engine comprising radial cylinders 23 with a common base portion 22 which is mounted to rotate on a spigot 13 and is rigidly supported on a spigot 20 connected to a power shaft 19. The spigot 13 is formed on the end of a spindle 10 secured in adjustable position by a lever 15 bolted to a bracket 18 on the end plate 3 of the outer casing 2, 3, 4. The cylinders are provided with wall ports 24, and with base ports 25 co-operating with ports 26 in the spigot 13, which communicate through a passage 27 in the spindle 10 with a coupling boss 28 formed on the bearing of the end plate 3. The spindles 10, 19 are eccentrically mounted in bearings 5, 6 in the end plates and are formed with shoulders 14, 21, between which the cylinder body rotates. The pistons are drilled and tapped axially forming at their ends seats for ball-bearings 33 which are held by large set screws 34 with cupped ends. Alternating leather washers and piston rings are held on the pistons by the screw. The ball bearings are pierced centrifugally into contact with a hardened steel ring 9 held between the halves 7, 8 of a crown or drum.

Title: Improvements in jointed doll limbs and in apparatus for making the joints
IPC: A63H3/46
Filed: 1920-08-09
Abstract: 170,697. Dietrich, J. G. Aug. 9, 1920. Hinges and pivots.-Relates to dolls having jointed members composed mainly of soft sheet metal, and consists in making the joints by forming on one member a boss or stud which enters a hole on another member, separation of the members being prevented bv flattening the top of the boss or by passing a rivet through it. The invention also comprises an appliance for flattening the boss. In the construction shown in section in Fig. 1, the member 2, which is of soft metal, has a tubular boss a punched in it. The member 1 fits over the tubular boss a and is secured by a rivet b the flat heads of which cover the hole. A spring may be coiled around the boss a between the member and the rivet head d to cause the members to be held by friction in any position to which they may be set. The boss may be formed with an inwardly directed flange at the top so that the rivet head c may be housed in the boss. In the construction shown in Fig. 8, the boss a is closed at the top, and then the members are assembled, the top of the boss is flattened out by means of a punch 7 to form a head, the boss a being fitted over a boss 6 formed on the flat head of an anvil 5. Both limbs may be made of soft metal and have a steel washer placed between them and another under the flattened bead of the boss. The punch and the anvil may be made with recesses 13, 10, Fig. 16<a>, respectively within which the members can lie. The boss 6 may have a convex top, thepunch being shaped to correspond, so that the head may be formed without causing the boss to bind the members together at the joint. The punch and the anvil may be tapered to facilitate holding them close to the work. Specification 148,915, [Class 132 (iii), Toys], is referred to.

The concentration of amine in the coagulating bath may be as low as 0.05% and is preferably 0.05 to 0.15%.  The salt index of the viscose is preferably 10 or higher and its temperature is preferably 40 DEG  C. or higher.  The spinning bath is preferably maintained at 40-80 DEG  C. and preferably contains 4-10% of sulphuric acid, 5-25% of sodium sulphate and 5-15% of zinc sulphate.
