Abstract: 1519091 Moulding and filling cups RHEON AUTOMATIC MACHINERY CO Ltd 5 Feb 1976 [3 April 1975 27 Aug 1975] 04629/76 Heading B8C At a single station of apparatus for filling cups with food materials 1 a cup is moulded from a blank cut from a sheet and is filled with material 1 from a hopper 2. Rollers 130, 131 fed the sheet which is of paper or aluminium foil, continuously and rollers 132, 133 the sheet intermittently, with a roller 141 on a pivoted arm taking up any slack. A female die 101 has a sheet clamping ring 111 and a cutting edge which as the die 101 is raised through an opening in a fixed cutting plate 112 cuts a blank from the sheet. In a modification, Fig. 28 (not shown) the clamping ring and cutting edge are mounted on a member suspended from the cutting plate and carried into a clamping and cutting position by upward movement of the female die. The die 101 then shapes the blank about a male mould formed by a filling nozzle 19. When the die 101 moves upwardly it moves a piston rod (109) in a cylinder causing suction to be applied through a tube 103 to a plate 102 which forms the bottom of the female die. The plate 102 grips the blank during cutting and moulding, and pulls the formed cup off the nozzle when the die 101 is lowered. The filling mechanism includes a rotatable cylinder 3 having an opening 7 which communicates with the hopper 2 when a piston (4) in the cylinder retracts and with the nozzle 19 when the piston advances. The drive for the piston includes a pivoted lever (49), (Fig. 3, not shown), whose fulcrum is adjustable to vary the stroke of the piston. If the food material is of a coherent nature there may be a rotatable cylinder 20 in the nozzle 19 with wires extending into the passageway in the nozzle to cut the food when the cylinder rotates. The filling mechanism 59 can be swung away from the die 19 for cleaning. There is a continuous drive for the apparatus, the intermittent drive for the various elements being derived from sector wheels or Geneva mechanisms.

Filed: 1965-02-04
Abstract: 1,143,403. Treating plants. NATIONAL DEVELOPMENT CORP. 4 May, 1966 [4 Feb., 1965], No. 4958/65. Heading A1E. [Also in Divisions G1 and G3] Horticultural apparatus including a chamber in which plants may be grown and a source of carbon dioxide connected to the chamber comprises means for sensing the concentration of carbon dioxide in the chamber and automatic control means for adjusting the rate of supply of carbon dioxide to the chamber from the source in dependence upon the concentration sensed. As illustrated the introduction of carbon dioxide into the chamber 1 from the source 3 is controlled by a valve 5 which is controlled in dependence or the concentration sensed by an automatic control 34. The sensing means comprises a pump 6 which draws off samples of the atmosphere in the chamber and introduces the sample in the form of bubbles into a tube 9 which contains substantially pure water, a conductivity sensing cell 15 and a chamber 26 containing ion exchange resin which de-ionises the water. The carbon dioxide is absorbed by the water in the tube 9 and bubbling of the sample will cause water to overflow into vessel 16. The conductivity of the water in the vessel 16 will vary according to the concentration of carbon dioxide therein, and the conductivity is measured by passing an electric current between electrodes 23, which together with the ionised water form one limb of a pontential divider circuit contained in the control 34. The resistance of the other limb is adjustable in accordance with a set value input 35 which may be set manually or automatically by a timer or temperature or solar radiation. If the rate of bubble flow falls below a predetermined value, thus indicating a failure in the supply of carbon dioxide, a photosensing device 31, 32 will cause, through control 34, the valve 5 to be closed.

Abstract: 1,048,954. Electric digital data-storage; counters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 8, 1965 [March 9, 1964], No. 5293/65. Headings G4A and G4C. Data entered into one end of a data register is propagated along to the vacant position nearest the other end under control of means sensing the presence or absence of data in each position. In Fig. 1 (not shown) one-bit bi-stable stages are respectively set (to 1) by a gate if presently at 0 with the preceding state at 1. Setting of a given stage resets (to 0) the previous stage. Exceptions to this general rule are that the first stage is set if presently at 0 with the register input at 1, and the last stage is reset by a readout pulse which also enables an output gate fed by the last stage. Thus the register stores all 1's received at the input in the stages nearest the output and not already occupied by 1's, until the register is full. Fig. 3 (not shown) shows a register in which each stage stores a four-bit character, and characters having at least one 1-bit are treated in the same way as 1-bits in the Fig. 1 (not shown) embodiment.
