Title: Gas mixing apparatus
IPC: B01F23/10
Filed: 1981-04-01
Abstract: First, second and third lines (1, 2, 3), for, for example, oxygen, air and an anaesthetic gas respectively, are connected to a common mixed gas outlet line (10). A first valve (11) and a second valve (12) are provided in the second and third lines (2, 3) respectively. The valves (11, 12) are connected to, and controlled by the pressure in, the first line (1). With an adequate pressure in the first line (1), the first valve (11) is closed and the second valve (12) is open. However, should the pressure in the first line (1) fall to or below a predetermined pressure, the first valve (11) is opened and the second valve (12) is closed. This can prevent anaesthetic gas alone being supplied (through the third line (3)), to the outlet line (10) in the event of a failure in the oxygen supply through the first line (1). <IMAGE>

Title: Preparation of 1,1-dichloro-4- methyl-1,3-pentadiene and intermediates therefor
IPC: C07C309/63
Filed: 1982-03-10
Abstract: A process is described for the preparation of 1,1-dichloro-4-methyl- 1,3-pentadiene in which 1,1,1,4- tetrachloro-2-hydroxy-4- methylpentane or an acylated derivative thereof is subjected to selective reductive elimination (e.g. with metal powder or by catalytic hydrogenation) to give 1,1,4-trichloro- 4-methyl-pent-1-ene.

Title: Insulation dispensing apparatus
IPC: B65G53/46
Filed: 1982-03-15
Abstract: An insulation dispensing machine has rotary feeding means 20 with a dividing or separating action between a hopper for divided insulation material e.g. mineral fibre material and a pump for feeding an outlet pipe or tube.

Patent GB-2111124-A (GB)
Title: A fuel injection nozzle for combustion engines
Inventor: FUSSNER PAUL
IPC: F02M61/08
Filed: 1982-12-01
Abstract: A piston (30) associated with the valve member (14) is subject to the fuel supply pressure and assists the fuel pressure acting on the valve member in opposition to the closure spring (16) during a first portion (h1) of the valve lift. Thereafter, the piston (30) is intercepted by an abutment (46) so that the valve member (14) is urged into its fully open position only under the influence of the fuel pressure acting directly thereon. In so doing, the main quantity of fuel is injected under increased pressure. The duration of the first portion of the lift is temporarily extended by the displacement of the piston (30) and undesirable oscillations of the valve member (14) are damped by the engaging piston stem (38). The jump in the fuel pressure at the end of the first lift portion (h1) can be established by appropriate selection of the effective areas on the piston (30) and on the valve member (14). <IMAGE>

Title: Lobster pots
Inventor: RIGHTON KEITH MICHAEL
IPC: A01K69/08
Filed: 1983-03-02
Abstract: A lobster pot is formed from a plurality of flat triangular panels which may be hinged together at common lines or may be formed separately and secured together in such a way that they can be folded with respect to one another. One of the panels (14) is flat and unpierced, whilst the others have major apertures in their body portions, which apertures are covered by suitable mesh or netting to prevent entrance of a lobster or shell fish intended to be caught by the pot through the opening. An entrance to the pot is formed by hinge lines a, b; b, c and d, e at apices D and D' which meet in the tetrahedron formed upon erection of the panels, and the triangular flaps thus formed act as a self closing opening to prevent the escape of lobsters once they have entered the pot. <IMAGE>

Title: Polarity-Sensitive D.C. Current Transformer
Inventor: AINSWORTH JOHN DESMOND
IPC: G01R19/14
Filed: 1984-03-07
Abstract: A D.C. current transformer (CT) (used to measure D.C.) comprising a common primary winding (B) and a pair of saturable magnetic cores (C1, C2) on which respective secondary windings (W1, W2) are wound and connected in opposite senses in series to a source of alternating e.m.f.

Title: Pressure Reducing and Regulating Valve
Inventor: LOUP RONALD LAMONT
IPC: F16K31/122
Filed: 1984-03-08
Abstract: A pressure reducing and regulating valve having a body with a body cavity 20 and a valve member 26 movable in the cavity. The valve member includes primary and vent seals 32, 50. At least one flow plate 36 is positioned in the body adjacent the container and includes primary 14, outlet 16 and vent ports 18. The valve member has the primary and vent seals 32, 50 positioned in the valve member on opposite sides of the central axis 28 of the member, allowing the member and thus the body to be of a smaller size, thereby reducing the pressure forces applied against the interior of the body. The primary and vent seals 32, 50 are spaced from the axis 28 at distances X, Y for reducing the side loading forces acting around the central axis as the member is moved. An adjustable screw Fig. 11, (not shown) engages a spring for adjusting the pressure flow through the valve and the screw includes one or more metal washers on each side of a shoulder on the screw coated with low friction material whereby the shoulder can be easily backed off from engagement with the body. <IMAGE>

Title: A radio frequency modulator
Inventor: YAMAGUCHI YOSHINOBU
IPC: H04N5/38
Filed: 1984-06-19
Abstract: A radio-frequency modulator for use in a videotape recorder set includes an electronic switch and a mechanical switch 8. The electronic switch consists of a diode 11, a choke coil 12, a bias resistor 14, and a diode 15 for blocking reverse current. When the electronic switch is closed, so that diode 11 is biased on, one of two tuning coils (5,6), both of which are associated with the PAL system, is automatically inserted into the closed circuitry. Thus, a sound carrier frequency of 5.0 MHz is obtained, depending on the position of the contact of the mechanical switch 8. When the electronic switch is open, so that diode 15 is off, these two tuning coils 5,6 are separated from the closed circuitry, and a sound carrier frequency of 4.5 MHz for the NTSC system is obtained. <IMAGE>
