Title: Single-ply bags in plastics material
IPC: B65D30/24
Filed: 1961-05-24
Abstract: 961,222. Valve bags. NATRO CELLULOSA S.p.A. May 24, 1961 [May 30, 1960; June 1, 1960 (2); June 25, 1960; Feb. 21, 1961], No. 18778/61. Heading B8K. A block-ended single ply valve bag is made of plastics material. In one embodiment a plastics tube has its ends cut and folded as shown in Fig. 11 so that the corner flaps c, c<SP>1</SP> which may form the valves extend beyond fold lines of side flaps e, e<SP>1</SP>. The flaps may be heat sealed together along the fold lines 12-13 and 12<SP>1</SP>-13<SP>1</SP>, and the side flaps folded about these lines so that they overlap and are sealed together. The side flaps and the end flaps may each differ in length. The bag may have two valves formed by the flaps c, c<SP>1</SP> at one end or may have one valve at each end, the other flap at each end being transversely heat sealed to the side flaps. In further modifications, Figs. 3 and 4, the bags are provided with perforations 17, 18 formed in the overlapping portions of the end flaps, or in the sides at 20 and covered by a sheet of material 19. The holes allow air to escape during filling of the bag but do not allow escape of the material. Various method of manufacture of the above bags are suggested, the seals may be formed by heat sealing adhesives or other means. The sealing may be high frequency heat sealing.

Title: Bulk cooking of tinned foodstuffs
IPC: A23L3/02
Filed: 1965-05-05
Abstract: 1,096,717. Heating and cooling food in cans. H. M. HAYWARD. May 5, 1965, No. 18858/65. Heading A2D. [Also in Division B8] In an apparatus for the bulk cooking of tinned fodstuff, the tins are passed in a single pass through a heating zone whilst being rotated alternately in one direction or the reverse direction and are then cooled whilst being continuously rotated. Tins 8 are fed down a shoot 62 into individual cages formed by transverse rods 7 of a roller link conveyer 4, 5 and supported from below by two pairs of parallel spaced rightangled support members 14, 15 at either end of the conveyer 4, 5. The centre section of the conveyer 4, 5 passes through a heating zone comprising four separately fed rectangular gas-fired heating chambers (Figs. 4, 5 not shown) each having a perforated spreader plate and horizontally disposed above this a nozzle plate having longitudinal slot-like nozzles for burning a gas-air mixture. A rectangular hood 42 covers the heating zone. Immediately below the conveyer 4, 5 in the heating zone and between the support members 14, 15 and slidable under the inner end parts thereof, are two further parallel spaced tin support members 16 connected to a crank mechanism (Fig. 3, not shown) to effect reciprocation of these members 16 just below and parallel to the line of movement of the top pass of the conveyer 4, 5. The speed of the reciprocation movement of the members 16 is greater than the linear speed of the conveyer and causes the tins 8 to rotate alternately in reverse directions throughout the time they are passing through the heating zone. On leaving the conveyer 4, 5, the tins 8 roll down a ramp 52 and on to a cooling conveyer 43 that embodies, as tin supports, two V belts which are driven in the reverse direction to and at a higher rate of travel than the conveyer 43 to produce continuous rotation of the tins 8 thereon. Cooling water is sprayed on to the tins 8 by jets 57 over a section of the conveyer 43 partly enclosed by a shield 59 and the used water is collected in a trough 60.

Abstract: An organic compound containing a polymerizable unsaturated linkage, or a mixture of such compounds, is polymerized by heating with a catalyst consisting of a dialkyl peroxide, R-O-O-R1, where R and R1 are unsubsituted alkyl groups.  Specified organic compounds are ethylene, vinyl thiolacetate, vinyl acetate, methyl methacrylate, vinyl methyl ether, styrene, carbon monoxide, trioxane, N - vinylphthalimide, propylene, vinylidene chloride, isobutylene, butadiene-1,3, isoprene, 2 - chloro - butadiene - 1,3, maleic anhydride, maleic and fumaric acid esters, vinyl esters, ethers and ketones, acrylic acids and esters, amides, nitriles, N-vinylamides, e.g. N-vinyl maleimide, N-vinyl succinimide, limonene, and carboxylic acid esters of unsaturated alcohols.  Specified catalysts are diethyl, dimethyl, dipropyl, propyl-ethyl and propyl-methyl peroxides. The preferred catalyst concentration is from 0.001 to 5 per cent, the temperature usually from 65 DEG  to 200 DEG  C., and pressure is generally employed.  Oxygen may be kept out of the apparatus by using an inert gas, e.g. nitrogen.

Title: Improvements in or relating to honing or the like machines
IPC: B24B39/00

Abstract: 592,665. Honing-machines. BRISTOL AEROPLANE CO., Ltd., WHITEHEAD, F. W., and LOVERING, W. G. Oct. 9, 1944, No. 19316. [Class 60] In honing work the surface of which is not regular, for example, turbine blades, the work is moved with its surface in contact with hones so mounted as to be free to follow the surface, and making line contact with the surface. The work shown in Fig. 9 as a turbine blade having a shank and a vane 21 with twisted concave and convex surfaces of varying curvatures, is mounted in a work head 23 carried by a pedestal 22, which also carries an electric motor 25 and a tool head 24 supporting the hones. The work head comprises a spindle 27 and a casing 28 having a bridgepiece slidable on vertical pillars on the pedestal 22 ; the shaft 27 is rotated and reciprocated, through a gear-box 26, by the motor 25. The -rotary movement of the shaft transmits an oscillatory movement to a jaw 29 in which the blade is secured, through a crank-pin 31, pivoted link 34 and rotary member 38; the blade thus simultaneously is reciprocated axially and oscillated about its axis. The tool head comprises a number of superposed units 40, three of which are shown in Fig. 3, each of which is formed with a base-plate carrying a pair of spaced stirrup members 42 each having a flange 43 which fits in a central aperture 63 in the next adjacent unit 40. The hones 44 are carried by radial arms 45 pivoted on axes n to lugs 46 projecting from the stirrup members 42, and the hones have convex operative surfaces which make line contact with the work. To provide for variation of thickness of the blade from root to tip, each arm 45 is made in two parts, namely a part 47 pivoted to the lug 46 and a part 48 having a pin 49 rotatably mounted in the part 47. Associated with each arm is a pair of cylinders 50, 51 formed in the stirrup members 42 and having therein plungers 52 which engage the part 47, compressed air being supplied to the cylinders by pipes 60, 61 and controlled by valves 56, 57 so that admission of air to cylinders 51 moves the hones to engage the work, and admission to cylinders 50 lifts the hones from the work ; a relief valve 62 'maintains a constant pressure in the pipes.

Abstract: 596,552. Control of D.C. motors. HIGGS, G. R., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 30, 1945, No. 19480. [Class 38(iii)] [Also in Group XXXV] In a system for maintaining constant engine speed and loading in an internal combustion engine-electric vehicle drive, the generator volts are controlled over the lower range of vehicle speeds by a servomotor responsive to engine speed and which, over a higher range of vehicle speeds controls the excitation of the traction motors. As shown in Fig. 1 excitation for the generator G and motor M is provided by an auxiliary machine X, regulation being effected by a two-sectioned rheostat LA, LB actuated by a reversible servomotor S controlled through a switch C operated by the engine governor. Upward movement of the slider of the rheostat from the position shown first strengthens the generator field GF and, when the section LA has been cut out, further upward movement progressively inserts the section LB in the motor field MF In a modified arrangement the motor is excited solely by a series field and movement of the rheostat slider beyond the position corresponding to maximum generator excitation progressively diverts current from the motor field.
