[Also in Group XVII] A process for the manufacture of containers having walls made of thin flexible sheets of thermo-weldable plastic material comprises injection moulding, at at least one of the extremities of the body, a reinforcing rib of the same plastic material onto those edges that are to be joined, the material being injected at a temperature sufficient to produce fusion of the plastic material constituting the thin walls. In Fig. 2, the mould comprises a dished outer part 33 having a gate 34, and a piston-shaped inner part 35 having an annular rubber gasket 36 for co-operating with a rim 37 on the part 33. In operation, a tube 38 of thermoplastic sheet material is stretched over the rubber gasket 36 and a thermoplastic end sheet 39 is placed on the inner part 35. The outer part 33 is then placed in position and a plastified thermoplastic material is injected through the gate 34 to form ribs uniting the tube 38 to the sheet 39. Strengthening ribs may at the same time be moulded onto the sheet 39. The container may be closed by flattening it at its upper end as in Fig. 4 and inserting the flattened end into an injection moulding machine for applying thereto a reinforcing strip 6 complete with handle 11, screwed spout 7 and screw cap 9. Fig. 6 is a cross-section through a mould for this purpose. It comprises two parts 20, 20a having cavities for making the parts 6, 7, 9 and 11, the spout-cavity 22 containing a core for forming the passage of the spout 7. The flattened top edges of the container walls 27 are inserted from below into the cavity 21, the base of the cavity 21 being sealed by a rubber gasket 29. An injection gate 25 is made in the mould part 21. Polyvinyl chloride and polythene are suitable plastics. Several different containers (see Group XVII) are described. The stiffening ribs may be reinforced by metal wires, fiber threads or other material of high tensile strength.

IPC: F15C1/12
Abstract: 1,051,255. Pure fluid amplifiers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug.26, 1963 [Aug.24, 1962], No. 33640/63. Heading G3H. [Also in Division G4] In a pure fluid amplifier a main jet flows normally along a wall 61 to an outlet 62 and can be caused to break away from the wall to discharge to an outlet 66 by a signal in a control nozzle 67. A relief opening 63 prevents back pressure in the outlet 62 from affecting the operation. An end wall 64 is located opposite the main jet between the outlets 62, 66 and is curved to redirect a small portion of the fluid towards the main jet to assist stabilization. The main jet is caused normally to follow the wall 61 by an asymmetrical arrangement or by low pressure in the control nozzle 67. The outlets may be cross-coupled with control nozzles to give a bistable device; the boundary wall 61 may be only rudimentary, e.g. in the form of a knife-edge; and two. or more inputs may lead to a control nozzle to provide an OR gate. The control nozzle 67 may open to a surface over which a perforated card or tape is passed so that the apparatus reads the perforations. An oscillator in Fig. 8 (not shown) has control nozzles 114, 122 which are fed from the main nozzle 120 through adjustable valves 123, 121 and the main flow tends to follow the wall 111. The outflow in the duct 112 is conveyed through a feedback channel 113 to the nozzle 114 to cause switching of the main flow to a duct 116, after which the flow reverts to the duct 112 due to the cessation of the feedback flow.

Abstract: 1,053,874. Etching. DOW CHEMICAL CO. March 26, 1964, No. 12813/64. Heading B6J. [Also in Division C7] Magnesium articles or articles of magnesium alloy containing at least 75% by weight magnesium are etched in a bath comprising 5-85 parts by volume phosphoric acid, 5-25 parts an aliphatic polyhydric alcohol, e.g. ethylene glycol or glycerine, the total of acid and alcohol not exceeding 100 parts, water to make up 100 parts as needed, and a nitrate of ammonium alkali metal or alkaline earth metal, e.g. sodium nitrate or magnesium nitrate in a proportion of 1-45% by weight of the above composition, at a temperature of 60-180‹ F., while maintaining relative motion between the bath and article for at least part of the time of immersion. Parts of the article not to be etched are masked off with a resist, e.g. polyvinyl chloride. The article may be first degreased in an aqueous alkaline solution, e.g. sodium carbonate and sodium hydroxide.

Abstract: 1,226,976. Refrigerating; defrosting. ELECTROLUX Ltd. 11 Nov., 1968 [17 Nov., 1967], No. 53291/68. Heading F4H. In a continuous cycle absorption system operating with inert gas and having a heat source which is thermostatically controlled, an additional thermosiphon pump is heated by the heat source and is charged with liquid by the increase in level in the absorber vessel on de-energizing the heat source, and the additional pump communicates with the evaporator which is thereby heated and defrosted for a short period each time the heat source is energized. As illustrated, the heat source 14 heats the additional pump 31 through the normal pump 12 so that in normal operation the additional pump is not overheated. When the thermostat de-energizes the heat source, the liquid level in the absorber vessel 10 rises from I to II and is sufficient to cause overflow of liquid from the normal vapour pipe 19 into a pipe 29 communicating with the pump 31 thereby charging the latter. When the system is restarted, the charge is expelled through a pipe 32 into the evaporator. During normal operation, a liquid seal is formed between the levels 33 and 34. In other embodiments, Figs. 2-5 (not shown), the additional pump may pass only liquid or vapour from its charge into the evaporator, the other phase being passed into the normal circuit, and the additional pump may receive its charge directly from the absorber vessel.

Abstract: 1,227,175. Hall plate devices. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. 22 May, 1968 [22 May, 1967], No. 24536/68. Heading H3T. [Also in Division G4] In a Hall plate multiplier, field coils 11, 12 (Fig. 1) are current energized proportionally to an analogue voltage between high impedance inputs 111, 112 connected to the control electrodes of M.O.S.T. field effect transistors 115, 116 whose drains are connected to control N- type F.E.T.'s 117, 118 whose drains are in turn connected to control P-type F.E.T.'s 119, 120 and subsequent N-type F.E.T.'s 121, 122 energizing the field coils. The drains of transistors 115 to 118 are resistance energized from positive source 123 while the sources of 115, 116 and 117, 118 are energized respectively from the collector of NPN transistor 125 over resistors and over Zener-diode 128 from the collector of NPN transistor 127; the transistors 125, 127 having common earthed bases and series resistance interconnected emitters with polarization Zener diode 126 and collectors connected to the junction of input resistors 113, 114. Drains of transistors 119, 120 are returned to negative of source 123 over RC noise filters 131, 133; 132, 134 while their sources are fed over PNP transistor 135 and Zener diode 136 from positive source 123. Balance in the field coils fed from transistors 121, 122 is adjusted by potentiometer 150, while source electrodes are returned to respective sources of 115, 116 for negative feedback. In the similar Fig. 2 (not shown) the drains of the output F.E.T.'s are connected to longitudinal ends of an indium arsenide Hall plate and to low resistance positive bias sources returned over resistances to the sources of the respectively opposite F.E.T.'s and over stop diodes to negative supply 223. The output of the Hall plate is connected to terminals through the slider and centre point of a balance potentiometer across the ends of the plate. This output is applied direct or through a filter to an amplifier (Fig. 3, not shown).
