Title: Vacuum moulding and trimming appts - the mould carrying the article being pushed into a cutting die
IPC: B29C31/00
Filed: 1973-04-18
Abstract: Appts. for thermoforming hollow plastics articles includes a relatively reciprocable mould passing through a cutting die, the edges of which shear the flash projecting beyond the mould. Pref. the sheet to be formed is heated on an apertured plate interposed between the mould and die and blown into the mould by air passing through the apertures in the plate. The plate is withdrawn and the mould and die moved into contact to effect trimming. The article is ejected from the mould into a take-off chute. Such a trimming arrangement is comparatively simple and cheap and enables automatic stacking to be effected. In several embodiments >1 mould/die combination and/or >1 heating plate is used to increase output. In one embodiment a rotating take-off device takes articles alternately from two moulds first to one stacking chute and then, when that chute is full to a second chute.

Title: Anti static sheet for greenhouses and cold frames - consists of wires carrying away charge embedded in plastic sheet
IPC: A01G9/14
Filed: 1973-05-11
Abstract: The plastic sheet can have one or two layers. When it has one layer a network of wires (2) is moulded into the sheet when it is made and the space between individual wires is of the order of a few centimetres. When the sheet is of two layer construction the wire net is placed between the two sheets and they are then firmly stuck together. A close contact between the net and the plastic sheet is essential. The ends of the wires protrude from the edges of the plastic sheet and are soldered to the metal frame that secures the sheet in place. This frame acts as a conductor to carry away the static charge.

Title: Continuous casting machine dummy bar connector - has pivoted jaws on pull-out bar which engage tongue on dummy bar and are held by sleeve
IPC: B22D11/08
Filed: 1973-06-07
Abstract: At the start of casting, the dummy bar head is positioned so that the T-shaped tongue on its lower end protrudes from the hole in the bottom of the basket through which the block is to be withdraw. The jaws on the end of the pull out bar can thus be placed round the tongue and fixed in position by a sleeve which slides on the upper part of the tongue fits round the outside of the jaws. After the initial withdrawal of the block, this securing ring comes up against the side of the hole through which the bar is being withdrawn and is retained there while the bar passes through. This brings the jaws outside the cage so that they open and release the tongue on the dummy bar head. The pull out bar can then be raised through the hole in he cage to engage directly the false piece in the bottom of the cast block. Time is saved in setting up at the beginning of casting and in engaging the block.

Title: Room humidifier attached to hot water radiator - has temp. responsive pilot device controlling water feed
IPC: F24D19/00
Filed: 1974-01-11
Abstract: The humidifier consists of an open tray (9) containing water which is evaporated by the heat of the radiator. An automatic feeder (24) attached to the tray has a supply passage (35) controlled at its upper end by a valve (34) and has a float chamber communicating with the water in the tray by a passage (37) below the minimum water level. The float (21) moves a lever (31) which operates the valve (34). The bottom end of the supply passage (35) is covered by a spring loaded piston (39) which has passages (44) communicating with the inlet of the feeder. The feeder is attached to the radiator vent cock so that the water pressure forces the piston back to allow water to flow through the piston passages (44) into the supply passage.

Title: Double glazed panel with tubular spacer - held clear of glass sheets by cold flow adhesive and by harder adhesive allowing pivoting of sheets
Inventor: SMITS DENIS L
IPC: E06B3/66
Filed: 1974-10-04
Abstract: A double glazed panel has a continuous tubular spacer centrally disposed between the marginal edges of the glass sheets, the sides of the spacer confronting the sheets each having a longitudinal groove defining a reservoir for a non-hardening cold flow adhesive, e.G. polyisobutylene, filling the inner portions of the gaps between the spacer and the sheets. The outer portions of the gaps, i.e. those nearer the edges of the sheets, are filled with a harder adhesive, e.g. a polysulphide, which extends into contact with converging parts of the sides of the spacer and allows pivotal movement of the sheets in response to wind and other loading. The spacer is filled with dessicant.

Title: Reception setting device for electronic teleprinter - corrects one-sided distortions occurring when signals are transmitted over single current line
IPC: H04L25/20
Filed: 1974-12-05
Abstract: In the teleprinter reception setting device the incoming signal flanks are applied to a delay circuit which differently delays flanks of different directions so that distortion so produced compensates the single side distortions. The signal flanks of one direction control directly, and those of the other direction through a NO circuit corresponding timing circuit with a monostable flip-flop each. The flip-flops output pulse width is adjusted by resistance and/or capacitance variation in the respective R.C. element. The input and output potentials of each monostable flip flop are connected through a NAND circuit, and output signals of both NAND circuits control a bistable flip-flop.

Title: Curved glass washing machine - has brushes with long flexible bristles running for entire length of transporter
IPC: C03C23/00
Filed: 1975-02-07
Abstract: The machine is particularly for the washing of curved windscreens, having a transporter and brushes one above the other for cleaning the top and bottom surfaces. The shafts (8) supporting the brushes (9) run horizontally for the entire length of the transporter and have very long and flexible bristles. Thus glass sheets of varying degrees of curvature are treated by the same brushes without the need to alter the shaft angles. The bristle length from the point of implantation in the shaft is between 20 and 70 cm, and bristles are of nylon or perlon, with a diameter between 0.2 and 0.8 mm. When seen in axial section the brush profile corresponds to the average curvature of windscreens treated.

Title: Prodn. of polylaurinlactam in a homophase system - reaction time is greatly reduced in this way
IPC: C08G69/18
Filed: 1976-01-22
Abstract: Polylaurinlactam is prepd. by hydrolytically polymerising laurin lactam in the presence of H2O, H3PO4 and a discarboxylic acid at 280-310 degrees C and 70-120 atmos. Water is removed by throttling the mixt. down to a press. of 0.1-0.005 atmos. under isothermal conditions at a flow rate of 20-90m/sec. The prepolymerisate is then polymerised at 280-300 degrees C in a 0.5-2mm. thick layer. Polylaurinlactam is widely used as insulation material for cables in the automobile and machine-building industries, for seals and gaskets and as containers for agricultural chemicals and oils. It is also used in the mfr. of filter fabrics, tooth brushes, special types of clothes, etc. Polymerisation time is greatly reduced compared with previous processes, because a homophase reaction system is used. In an example, polylaurinlactam was prepd. from a laurin lactam melt contg. 10 wt.% H2O, 0.2 wt.% H3PO4 and 0.2 wt.% adipic acid. The process is >=4-6 times faster than previous continuous processes.
