Patent GB-1216862-A (GB)
Title: Apparatus for moulding hollow articles
Inventor: COOKSON HAROLD
IPC: B29C51/22
Filed: 1968-06-25
Abstract: 1,216,862. Forming or lining containers. METAL BOX CO. Ltd. 19 May, 1969 [25 June, 1968], No. 30236/68. Heading B5A. Hollow articles or containers are formed in apparatus comprising a plurality of moulds 1 equi-spaced and supported for rotation around a fixed axis 3, the longitudinal axes 4 of the moulds being radial of the axis, the outermost end 5 of the mould being open. A blowing head 6 is mounted for movement into and out of sealing engagement with the mould which may be sectional. A strip 8 of softened thermoplastics is fed, e.g., from an extruder, over roller 7 across the open ends 5 of the moulds as they rotate and at a speed equal to the speed of the moulds, the blowing head 6 then sealing the strip against the mould 1 and air is admitted therefrom into the mould to expand the strip thereinto. The shaping may be assisted by plunger 14 and the container may be given a recessed bottom by means of 'punt former' 16 actuated by roller 18 in cam slot 19 against spring 17 as the apparatus rotates. The blown container may be removed from the strip by roller 20 pressing against rim 22 of the mould, remaining strip being recirculated to the extruder. The strip may be formed of alternating thickness, the thicker sections being used for the areas to be moulded, or the strip may be contoured, e.g. corrugated, to provide grooved or other surfaces in the article. The strip may also be of a plurality of layers, e.g. of differing gloss or permeability characteristics. The apparatus may also be used for lining containers, e.g. of metal, placed in the moulds.

Title: A device for attaching locks to trunks, suitcases, bags or the like
IPC: E05B17/00
Filed: 1950-12-11
Abstract: 699,750. Attaching pronged fasteners. AMIET, F., and HOPMANN, R., [trading as AMIET & HOFMANN]. Dec. 11, 1950 [Dec. 15, 1949], No. 30245/50. Class 89 (iii). In a machine for attaching pronged locks to trunks &c. in which the members for bending over the prongs can operate only after the prongs have pierced the material of the trunk, an arm 6 carrying the lock is pivoted to an arm 2 in which the bending members 29 are mounted. The lock is held by a spring tongue 37 in a recess 36 of a support 34, 35 which is secured to the arm 6. The pivoted bending members 29 are arranged in a recess 28 in a support 27 and are raised from the dotted to the full-line position by pins 31 on a member 22 which is secured to the arm 2. Downward movement of the support 27 is prevented by a rod 16 engaging under a pin 32 until the prongs on the lock have pierced the material of the trunk. Two pairs of arms 2, 6 may be provided at an adjustable distance apart. The machine is operated by a pedal 14, link 12 and lever 10.
Patent GB-427808-A (GB)
Title: Improvements in or relating to valve gear for multi-cylinder internal-combustion engines
IPC: F01L1/42
Filed: 1933-10-31
Abstract: 427,808. Valve gear. BRISTOL AEROPLANE CO., Ltd., and FEDDEN, A. H. R., Filton House, Bristol. Oct. 31, 1933, No. 30252. [Class 7 (vi)] In an engine having a number of valveoperating shafts distributed around a main driving-shaft, the valve-operating shafts are arranged in separate groups, the shafts of each group being geared together and to a pinion on the driving-shaft by a separate gear train for each group. The Figure shows an arrangement for a nine-cylinder radial sleeve-valve engine, in which the shafts of the nine sleeve-driving pinions 11 .. 19 are arranged in three groups about the central driving-pinion 21, each group having a separate gear train. Thus a compound idler gear 23 meshing with the pinion 21 drives the sleeve pinion 12 which actuates the sleeve pinions 11, 13 through idlers 26. Similarly, an idler gear 24 drives the sleeve pinions 14, 15, 16, and a third idler gear 25 the sleeve pinions 17, 18, 19. The cylinder and sleevevalve axes are indicated by the radii 1 .. 9, and the positions of the valve-actuating cranks by full lines drawn radially on the sleeve pinions, that for the pinion 11 being at A, and that for the pinion 12 at D. The pinions are made interchangeable one with the other. In order that the idler gears 23, 24, 25 may be interchangeable, the number of teeth on the pinion 21 must be a whole-number multiple of the number of groups of shafts. In order that the sleeve pinions 11 .. 19 may be interchangeable, the sum of the arcs AB, BC, and CD, measured in the direction of rotation of any two pinions and of the idler 26 connecting them, must be equal to a whole number of gear teeth. As an alternative, the outer pinions of a group may be of less face width than the middle pinions 12, 15, 18, so that these latter are interchangeable only among themselves. For ensuring correct assembling of the gears, each pinion is connected to its shaft by a splined arrangement having a master spline, or by other key devices ensuring that the pinion can be placed only in one angular position, and marks are scribed on the gear casing to indicate the correct positions of the valve-driving cranks. Alternatively, holes may be provided in the gears and casing to be brought into register, or an assembling jig may be used to hold all the sleeve cranks in position.

Title: Coating composition
IPC: A23B7/16
Filed: 1959-09-04
Abstract: An emulsion for use in treating fruit trees and their fruits comprises in water: 10 to 70% by weight of a hydrocarbon wax, e.g. paraffin wax, microcrystalline wax or petrolatum, 0 to 5% of an oil soluble non-ionic emulsifier, 1 to 5% of a water soluble non-ionic emulsifier, the wax being present in the composition in finely divided homogenized form so as to form a highly stable wax emulsion with or without a fungicide.  When the water-soluble emulsifier has fairly good oil solubility it can serve as both the oilsoluble and the water-soluble emulsifier but must be used in high concentration to provide any reasonable amount of oil solubility viz. 4 to 5%.

Abstract: 450,912. Waterproofing boots and shoes. VERY, R., Plechatel, Ille et Vilaine, France. Nov. 5, 1935, No. 30549. Drawings to Specification. [Class 17 (ii)] Unvulcanized rubber, such as rubber solution, or rubber latex, and containing vulcanizing ingredients, such as sulphur and zinc oxide, or a strip of vulcanized or unvulcanized rubber secured by an adhesive containing vulcanizing ingredients, is applied or secured, as the case may be, to one or both of two opposing faces of parts of footwear through which holes are formed in the sewing or stitching operations, e.g. the marginal portion of the upper and lining, and an accelerator or accelerators is applied before or after the sewing or stitching operation which in conjunction with the lasting and sewing pressures effects cold vulcanization of the rubber in the region of the stitches to seal up the holes and render the shoe watertight. The unvulcanized rubber may be caused to take up the vulcanizing ingredients by passing it in strip form through a liquor containing carbon tetrachloride, zinc, oxide and sulphur. If desired, the accelerator may be mixed with the rubber and vulcanizing ingredients or with one portion or batch thereof. Specifications 369,599 and 414,080 are referred to.

Title: Improvements in or relating to electric remote control systems
IPC: G05D3/14
Filed: 1938-10-24
Abstract: 520,497. Electric distant control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 24, 1938, No. 30705. Convention date, Oct. 23, 1937. [Class 40 (i)] The receiver of a control system comprises an A.C. motor which is at rest when the phases of the field flux and the armature current are in quadrature. An alteration of the phase of the field flux causes the motor to run adjusting a phase shifting network in the armature circuit until the quadrature relationship is re-established. In the system shown, which is for tuning a wireless receiver, the tuning condensers 39 are operated by a motor having an armature 35 supplied from the power network 1, 2 through a phase adjuster 37 and a field 34 connected in the anode circuits of phase detectors 22, 23. The grids are supplied from the secondary 19 of a transformer 20 and are normally biassed by a battery 16 to prevent operation of the valves. The biassing circuit also includes a rectifier 21 connected across a tuned circuit 27, 28 which is responsive to control signals transmitted over the network from a control valve oscillator 3 supplied from the network through an adjustable phase shift network 9. Normally the phases of the armature and field currents of the motor are in quadrature and no torque is developed but when the phase of the modulation envelope of the control signals is altered by the network 9, the motor is operated until the normal phase relationship is re-established by operation of the phase adjuster 37 by the motor.
