Title: Improvements in or relating to indicating mechanism
IPC: G01P3/26
Filed: 1941-11-20
Abstract: 554,159. Comparison-speed indicators. STEVENS, A. H. (Aluminium Laboratories, Ltd.). Nov. 20, 1941, No. 14962. [Class 106 (iii)] A moving part the speed of which is required is arranged to transfer movement to a column of liquid which for comparison is observable against an indicator moved at a predetermined regulable and constant speed. The ram 14 of an extrusion press is connected to a plunger 20 moving in a hydraulic cylinder 21 connected by a pipe 24 at the end away from the plunger to a vessel 25 connected in turn by pipe 27 to a tubular column 28 having a window 29 and through a valve 32 to a receptacle 31 of greater cross-section than column 28. Adjacent the column 28 is comparison-speed indicator in the form of a belt 35 driven from a motor 38 at the predetermined speed for a correct speed of the ram 14. The speed of the motor may be varied for instance by a rheostat 39 if it is desired to operate the ram at some other predetermined speed. With the ram fully retracted, and valves 41, 32 open, coloured liquid is delivered through the pipe 40 until it rises to a suitable height in column 28 and vessel 31. The valves are now closed. With the main valves 17, 18 of the apparatus open, the valve 17 is set by experiment so that the speed of the ram 14 is such as to effect the desired product. The motor 38 is thus started and regulated so that the liquid in column 28 moves in step with the marks on the band 35. Thereafter, whenever the same extrusion conditions exist, the operator starts the motor and adjusts valve 17 until the liquid in column 28 is in step with the band. If the liquid displaced from cylinder 21'exceeds the capacity of tube 28, it will be discharged into vessel 31 which is provided with a graduated window 45. The column 28 may also be graduated. By opening the valve 32 and allowing the liquid in vessel 31 and column 28 to come to the same level the position of the ram 14 is indicated. A worm driven helix may be substituted for the band.

Title: Improvements in or relating to strengthened reinforced structures
Filed: 1952-06-17
Abstract: 748,395. Boats. LASZLO, P. D. DE. Sept. 16, 1953 [June 17, 1952; Dec. 18, 1952], Nos. 15236/52 and 32238/52. Class 113. [Also in Group VIII] A strengthened reinforced structure suitable for boat hulls is constructed by coating at least one layer of reinforcing material with a synthetic resin, the said structure having a rib-like strengthening on it, the rib being also made of reinforcing material and synthetic resin and being formed over a former consisting of a series of substantially independent elements joined together so as to provide a flexible composite elongated former over which further reinforcing material is laid, said composite former having flexibility to follow the curve of a surface but presenting appreciable rigidity in the direction perpendicular to the surface. A double-skin construction may be obtained by bridging the tops of the ribs with further reinforcing material. As shown (Fig. 1) a mould is covered with sheets of glass fibre reinforcing material 10, 11 permeated with a synthetic resin which may be cold-curing, and layers 12, 13 of the same material are laid over a V-section channel former 14 to provide the rib-like strengthening member. The former may be of sheet aluminium, polythene or of leatheroid, bent to form inclined sides 14a, 14b (Fig. 2), a flat top 14c, and inturned feet 14d. The channel so formed is slit at 14e at regular intervals to form short lengths: the slits are relatively wide and include the feet 14d but not the top 14c which is continuous. If desired, the former may be made of individual synthetic resin mouldings or light alloy castings secured along the top by adhesive tape or joined by passing nylon thread through registering holes in each casting. When the former is made of a material to which the resin on the reinforcing material will not adhere (such as polystyrene) it may be withdrawn. Sheets 12 and 13 cover not only the former but at least part of the first layers exposed between the formers. Fig. 4 shows a double-skin construction. The base layer 20 is laid on the mould and a series of formers 21, 22, 23, 24 laid at intervals upon it. One more or less continuous sheet 25 of the fabric is laid over all the formers, and resin applied thereto. The vertices of the formers are bridged by further sheets of reinforcing material: sheet 26 bridges formers 23, 24 and extends down those sides further from each other, terminating on the base layer. The layer 27 starts at the top of 24, bridges 23 and 22 and extends down the further side of 22 to terminate on 25. Similarly the next sheet starts at the top of 23, bridges 22 and 21 and extends down the further side of 21 on to layer 25. On completing the assembly, the resin is cured.

Title: Improvements in controlling mechanism for windows, doors, panels and like sliding elements
Inventor: PERNETTA CHARLES
IPC: E05D13/00
Filed: 1953-06-01
Abstract: 741,755. Sash balance. BECKETT, LAYCOCK & WATKINSON, Ltd. Aug. 24, 1954 [June 1, 1953], No. 15253/53. Addition to 723,056. Class 20(3). A control mechanism for balancing the weight of a sliding panel, e.g. a vertically sliding window in the side door of a vehicle, comprises a flat spiral spring of the kind which normally coils up closely upon itself and in which the uncoiling movement of the spring is effected by applying tension to unroll the outer end of the coil whilst supporting the remaining coiled convolutions for free rotation as a unit without producing any substantial movement of any coiled convolution radially, or circumferentially, relatively to an adjacent coiled convolution, the uncoiled portion of the spring being anchored adjacent one face of the panel the lower edge of which is engaged between the body of the coil and the uncoiled portion of the spring. A glass panel 13, mounted in guides, not shown, to slide downwards in a pocket 12 when the window is opened, or to be raised to close an aperture above the waist rail 11 of a vehicle door, has its lower edge 17, with, or without, a metal frame 19, supported between the body 18 of a flat spiral spring 23 and the uncoiled portion 16 thereof, the upper end 14 of the spring being secured at 15 to the waist rail 11. The friction of the channel guides and the upward force of the spring is sufficient to maintain the panel 13 in its adjusted position. If desired, additional frictional control and adjustable locking devices can be used. In a modification a channel section metal frame, on the lower edge of the panel is provided with a downwardly directed flange which engages with the spring, and may be provided with a frame member, such as 19, or with a pad which may be impregnated with material, e.g. oil to protect the spring.

It is stated that when the emulsifying agent is based on a high 1,2-polybutadiene, the vinyl monomer graft polymerizes on to the emulsifying agent (numerous examples use such emulsifying agents). In Examples 1-26, 36 and 40-51, butyl methacrylate is homo-polymerized using as catalyst ammonium persulphate, potassium persulphate, either of these persulphates mixed with cobalt and lead naphthenates, azobisisobutyronitrile, FeCl 3 /M 2 O 2 , PeCl 2 /H 2 O 2 , γ- rays (Examples 44 and 47), or a mixture of cobalt naphthenate with potassium persulphate, azobisisobutyronitrile or FeCl 2 /H 2 O 2 . In some of these examples butyl or methyl "Cellosolve" (Registered Trade Mark) is also present. In Examples 30 and 37-39, styrene/butyl acrylate copolymers are prepared in the presence of potassium persulphate. In Examples 27-29 and 31-35, the following monomers and monomer mixtures are polymerized in the presence of ammonium or potassium persulphate: ethyl methacrylate, styrene, butyl methacrylate/ acrylamide, ethyl acrylate/acrylic acid/styrene/ acrylonitrile, methyl methacrylate/lauryl methacrylate, methyl methacrylate / 2 - ethylhexyl acrylate / glycidyl methacrylate and vinyl toluene/isoprene. The products of the above emulsion polymerization are used as coating compositions, and may be used to form paints and adhesives. Examples are given of paint formulations comprising titanium white together with butyl methacrylate homopolymer latices and a butyl acrylate/styrene copolymer latex.
