IPC: B29C65/00
Filed: 1970-06-18
Abstract: 1,265,923. Seaming non-metallic sheet material. STICHTING ONTWIKKELING VERPAKKINGSMETHODEN IN DE ZUIVELINDUSTRIE. 18 June, 1970 [18 June, 1969], No. 29592/70. Heading B5K. One or more thermoplastic foam films or foam sheets with a density below 250 kg. per cubic meter, preferably below 100 kg. per cubic meter, are sealed by overlapping the films or sheets without a bonding agent therebetween, enclosing the films or sheets at least substantially on all sides in dies 1, 2, 7, 8 adapted to compress them at a temperature above the softening point of the plastics material, foaming again the compressed product at the same temperature by decreasing the pressure, and sealing at a predetermined foam thickness by cooling at least one side. Preferably, the pressure is decreased by increasing the distance between the die sections until a predetermined foam thickness is reached. The pressure applied to the films or sheets enclosed in the dies is at least 2 kg. per square cm. If the films or sheets consist of polystyrene foam having a density of 40 kg. per cubic m., they are sealed at a pressure of 4 kg. per sq. cm. and a temperature of 120-130 C., e.g. 128 C. In another example, two cross-linked polypropylene foam sheets having a density of 70 kg. per cubic m. are sealed in 4 seconds at a pressure of 20 kg. per sq. cm. at a die temperature of 185 C. Other specified foam plastics compositions are polystyrene-rubber compositions, polyvinyl chloride, copolymers of vinyl derivatives, polyethylene and polypropylene and their copolymers and acrylonitrile-butadiene-styrene compositions.  A container, Figs. 1 and 2, is made by folding a foam plastics blank 9 about a heated mandrel 1 with the upper flaps 11, 12, 13, 14 folded as shown in Fig. 2. The external planes of the blank are enclosed and compressed by heated die halves 7, 8 and a heated plunger 2. The pressure is reduced and the distance between the parts 2, 7, 8 and the mandrel 1 is increased to allow foaming. Cooling is then effected either by cooling the parts 2, 7, 8 or by removing these parts and shifting the mandrel 1 to another position in which cold or cooled parts 2, 7, 8 are applied to the blank.

Abstract: 1,266,207. Reciprocating generators. O. C. SELDEN. 25 Aug., 1970 [5 Sept., 1969], No. 44024/69. Heading H2A. In a modification of the dynamo-electric pulse generator of Specification 1,263,789, movement of the bi-stable pivoted armature 20 to reduce the gap (between 24 and 25) in the first magnetic circuit simultaneously opens a gap (between 25 and 50) in a further magnetic circuit, thereby increasing the force which needs to be applied to the key 28 to initiate, such movement. In Fig. 1 the further magnetic circuit includes the permanent magnet 12 and armature 20 (in common with the first magnetic circuit), a stud 50, the top mounting plate 1 and a bolt 3, which are now both made of magnetic material, and the lower mounting plate 2. In another embodiment (Fig. 2, not shown) the two-pulse generator of Specification 1,263,789 is modified so that its second air gap closes completely.

Abstract: 1,267,239. Welding by pressure; removing weld flash. BECKER-PRUNTE G.m.b.H. 2 June, 1969 [1 June, 1968 (2); 10 April, 1969], No. 27898/69. Headings B3L and B3R. A chain welding machine of the type in which the chain passes twice through the machine to complete the welding of the horizontal and vertical links has a welding station and a subsequent flash removal station at which the still red-hot flash can be removed from a welded link simultaneously with the flash-butt welding of a succeedinglink, the clamping arrangement at the two stations being such that play is left between the two clamped links. A movable clamping jaw 9 is lowered to hold a link 8 from which flash is to be removed on to a fixed jaw 16 and an extension 11 on the jaw 9 simultaneously forces down the next horizontal link on to jaws 13b, 14b of two electrodes 13, 14 forming part of a welding bed. The movable electrode jaw 14a may be lowered on to the link to grip it at this stage and a horizontally movable member 115 (Fig. 9 III) may be used to displace the link to be welded to one side of the path of the chain; the movable press jaw 122 (shown as 15 in Fig. 2) moves the link 102a forwardly against a fixed press jaw 121 thereby creating a small degree of play b between the two clamped links. The movable electrode parts are lowered on to the limb of the link to be welded adjacent to the weld point 120 and flash butt welding performed by advance and release of pressure on the movable press jaw 122. The adjacent electrode may be mounted on a common slide with the movable press jaw. In an alternative arrangement the link to be welded is gripped by a pincer-shaped tool for insertion in the welding bed. Drive means for advancing the chain either cyclically or continuously are described (Figs. 18-21, not shown); these consist essentially of two inclined discs the gap between which is variable under spring loading, the region of minimum distance between the discs serving to grip the limbs of vertically disposed links sufficiently to drive the chain frictionally. The drive may include a oneway clutch device to provide a step by step feed of the chain. Weld flash 105 (Fig. 16) is removed by the stroke of two shaped tools 140, 141 the cutting edges of which mutually overlap. Hydraulic means may be used to move the flash removal tools as also the clamping jaws. Reference has been directed by the Comptroller to Specification 1,199,427.

Title: Controlled environment apparatus and process for plant husbandry
IPC: A01G9/18
Filed: 1971-03-31
Abstract: 1349001 Air conditioning ENVIRONMENT ONE CORP 31 March 1971 8315/71 Heading F4V [Also in Division A1] An apparatus for growing plants in a controlled environment comprises a growing chamber 3 and a removable top section 8 which contains fluorescent lights 31 and incandescent lights, the latter serving to heat the growing chamber 3 and being controlled by a thermostat 80 therein. The lights are turned on and off by a timer 20. A fan 37 powered by an electric motor 39 draws outside air through pivotable louvres 36 at one end of the top section 8, and circulates it past the motor 39 and the lights to cool them; the air leaves through louvres 40. A fan 42 powered by the motor 39 circulates air through the growing chamber 3 when a vent valve 43 is open. Carbon dioxide is supplied to the growing chamber 3 from a control volume chamber 60; this is supplied from an exchangeable pressurized cylinder 52 via a pressure regulator 53, adjustable by means of a linkage from a control panel 16, and via a three-way valve 57. An expansible chamber actuator 44 is connected to the control volume chamber 60, so that while the latter is pressurized the actuator 44 acts to hold the vent valve 43 open against spring pressure. When the timer 20 actuates the lights it also actuates a solenoid 63 which rotates the three-way valve 57 to cut off the cylinder 52 and connect the control volume chamber 60 to the growing chamber 3 via line 62; the vent valve 43 then closes since the actuator 44 is also vented to the lower pressure in the growing chamber 3. The pressure regulator 53 is connected to a dial 17 on the control panel 16 which can be calibrated to indicate the carbon dioxide concentration in the growing chamber 3. The relative humidity is maintained at a high level in the presence of the carbon dioxide, the plants being held in soil in holed plant pots 1 supported on spaced slats above a reservoir of liquid nutrient. Manual override switches may be provided on the control panel. An automatic electric coupling 70 connects the top section 8 to the remainder of the apparatus when the top section 8 is placed in position.

Filed: 1997-03-14
Abstract: A method and apparatus for controlling data flow on a network having a server and a non-blocking client node in which the client node may not drop requests received from the server. A process on the non-blocking client node allocates resources on the non-blocking client node and notifies the server of the allocated resources. The server then determines the resources on the non-blocking client node required to fulfill a request by an application on the server and whether sufficient resources are available on the non-blocking client node to fulfill the request by the application. If sufficient resources are available, the server then sends the request to the client node and if sufficient resources do not exist, the server waits until sufficient resources do exist to issue the request to the non-blocking client node.
