Title: Mechanically operated dispensing device with expansible bulb
IPC: B05B11/02
Filed: 1979-07-24
Abstract: The purpose of this invention is to provide an aerosol dispenser, which does not rely upon atmosphere deteriorating chemical propellants for discharging the product, wherein a long duration, high pressure spray or discharge of the product is obtained. An easy to operate dispensing device has a rotatable actuator (20) connected with an expansible chamber (P, 51, 52) to effect operation of the expansible chamber to draw material to be dispensed from a container (C) into the expansible chamber (P, 51, 52) and to then pressurize the material. An expansible bulb (B) is connected with the expansible chamber and with a dispensing nozzle (H.90), and has a volumetric capacity several times as great as the expansible chamber. Valves (94, 96, 97, 98) are associated with the bulb control flow into and out of the bulb. The relative sizes of the expansible chamber and bulb are such that a hydraulic force multiplication is obtained from the expansible chamber into the bulb.

Title: Silencing flow of liquid
Inventor: KITCHEN PATRICK
IPC: F16K47/02
Filed: 1981-07-08
Abstract: To quieten the noise of water passing through the ball-valve 40 of a cistern 41 a thin-walled collapsible sleeve 20, e.g. polythene lay-flat tubing, is connected to the outlet port 44 of the ball-valve. The sleeve is coupled to the port by a plastics tube 10, and a strap 30 is used to secure the sleeve to the tube and the tube to the ball valve. The upper end (11, Fig 1 not shown) of tube 10 is tapered and it has a circumferential central rib 14 which is engaged by the edges of a circular aperture (31, Fig 3 not shown) in the strap. The sleeve 20 introduces water below the level of water already in cistern 41. If there is a tendency for siphoning or suck-back of the water, the sleeve collapses to prevent this and remains collapsed until normal flow resumes. This also reduces the noise. <IMAGE>

Title: Holding a thermally deflectable member of a machine tool against mispositioning
Inventor: INOUE KIYOSHI
IPC: B23D57/00
Filed: 1982-02-16
Abstract: A work element supported by a thermally deflectable member (8) in an operating machine tool (1) is held against mispositioning by causing a fluid (F) to flow through a passage (22, 23, 27, 28) formed in the member (5, 6, 8) of the machine tool (1) performing a machining operation to hold the member (8) in a heat- exchanging relationship with the fluid (F) and maintaining the difference in temperature between the fluid flowing into the passage of the member and the fluid flowing out of that passage substantially constant. Two thermistors (33, 34) are used to detect the temperatures of the flowing fluid at an inlet side and at an outlet side, respectively, and a signal representing a temperature difference detected is compared with a threshold value representing a preselected temperature difference to provide a deviation signal which is used to control the rate of flow of the fluid through the passage and/or the temperature of the flow-in fluid. Preferably, the latter is held constant and the former is controlled in response to the deviation or control signal. <IMAGE>

Title: Method and apparatus for arc butt welding
IPC: B23K9/08
Filed: 1982-03-10
Abstract: This invention relates to the joining of two parts by an arc buff welding process in which an arc is struck across a gap between the two faces (10, 12) to be joined and is subjected by solenoids 14, 16 to a magnetic field to cause it to move over the two faces for a period sufficient to heat the faces. The heated faces are then brought together and a forging pressure is applied across them. In the method of the invention, for a final portion of the arc heating period, the value of the arc current is significantly increased above its value during a preceding portion of the arc heating period, and before the final portion of the arc heating period, the value of the arc gap between the faces is increased above its value during the preceding portion of the arc heating period, thereby preventing short-circuit during the final portion of the arc heating period. <IMAGE>

Title: A method of carrying out crack tests and a test body for this method
Inventor: GOEKE FRIEDHELM
IPC: G01N3/02
Filed: 1982-11-05
Abstract: In a method for measuring the length of the cracks and/or the progress of cracks in test bodies, samples of material and components, the surface of the body is pre-treated by grinding an area of the test body, applying a reflective coating, and the body is then subjected to load. The surface (2) of the test area (5) is coated after grinding with a thin layer (3) comprising a transparent lacquer which cracks with the test body (1). The test area (5) is irradiated by an illumination device (4) at an acute angle of incidence ( alpha ), producing substantially total reflection on the layer (3) of lacquer. Due to reflection and refractive effects at the crack area of the layer of lacquer there is a clear high contrast representation of the crack viewable e.g. by camera 6, from a position not reached by radiation reflected by the lacquer surface. <IMAGE>

IPC: B60K5/12
Filed: 1983-04-08
Abstract: A chamber is formed by a box- like body which is made of rigid material and whose one open end is closed by a flexible wall 22. A liquid or plastic material (in general, said material has a viscosity not lower than 50,000 centipoises) fills said chamber. The body is mounted on a supporting structure e.g. a vehicle. A rigid rod 23, connected to an oscillating mass e.g. the engine and extending through said wall 22, has one end thereof in said material and said one end carries a plate-like annulus 30. In one embodiment, movement of the rod moves the plate (fixed directly to the rod) in said material. In other embodiments, movement of the rod moves a device (fixed directly to the rod) which only engages the plate if the oscillation amplitude is greater than a predetermined minimum. The thickness of the wall, made of elastomeric material, may vary from portion to portion. This variation, or the movable mounting of the plate, enables high frequency oscillations to be accommodated without damping. <IMAGE>
