Title: Spiral flow baffle system
Inventor: SMITH CLOYD DANIEL
IPC: F01N3/033
Filed: 1965-11-23
Abstract: 1,093,630. Centrifugal separators. C. D. SMITH. Nov. 23, 1965, No. 49728/65. Heading B2P. [Also in Divisions Fl and G3] A fluid flow control device comprises a perforated tube 32 extending into a chamber 16 in which a baffle assembly is formed in the tube to provide two spiral flow paths. The baffle assembly comprises pairs of baffles 54 each consisting of opposed plates 54a, 54b located on opposite sides of an axial plane. The plates intersect on the axis and the tip of a plate joins the tip of the plate of an adjacent pair on the opposite side of the axial plane. In the embodiment shown the device is used as a centrifugal separator and the tube is surrounded by fibrous material 46. The substance to be centrifuged passes through an inlet 38 to the tube and flows through the spiral paths where the more dense substances pass through the perforations. The substances leaving the spiral paths then flows to an outlet 28. The device may be used to separate liquids from gases or vapours, solids from liquids or gases, fluids of different densities or solids of different densities. The plates may be fixed to an axial rod 58 which may be rotated by a knob 60 to clean the perforated tube. In a modification the plates are stamped from sheet metal to form alternate plates of the pairs. In a further modification Fig. 3 (not shown) the device is used in a "straight through" silencer, the chamber surrounding the tube being filled with accoustically absorbent material and the housing having a drain plug for liquid separated through the tube.

Title: Electrophotographic contact duplicating method and apparatus
IPC: G03G15/22
Filed: 1976-11-30
Abstract: Images are applied, from a film (10) coming from a roll (14), onto an electrophotographic film (12) coming from a roll (18). A thin layer of insulating hydrocarbon (41) is applied to the electrophotographic film (12) before it comes into contact with the film (10), so as to prevent an electrostatic discharge when the two films are separated. The films (10 and 12) of the two rolls (14 and 18) are brought into contact and transferred to a projection unit (22) where a light beam is projected onto and through them. The electrophotographic film (12) is charged just before it comes into contact with the photographic film. A toner-applying unit (46) and a fixing unit (54) are arranged so as to act on the electrophotographic film after its exposure. The subsequent transfer of the image supplied with toner, onto a base film strip, is provided in order to enable the electrophotographic film (12) to be reused later. <IMAGE>

Title: Improvements in or relating to Cameras
IPC: G03B15/04
Filed: 1966-11-08
Abstract: 1,167,514. Photographic flash apparatus. BALDA-KAMERAWERK RUDOLF GRTER K. G. Nov. 8, 1966 [Nov. 16, 1965], No. 49946/66. Heading G2A. A camera having a shutter-release lever 3 operated by a manually operated control plunger 10 is provided with a receptacle 22 having a rotatable holder 23 for a flash cube and with electrical contacts (51, 52, Fig. 3, not shown), there being stepwise rotating means for rotating an inserted cube actuated upon release of the member 10 when the shutter is set for flash exposures. The camera is shown set for daylight exposure only. To make a direct or indirect flash exposure a ring 20 is rotated so that the receptacle and holder take up one of two positions with the contacts (51, 52) connected as required. This rotation causes a slide 6 to be moved by means of a pin 8 following a recess (46) in a flange (45) of the receptacle, movement of the slide allowing a flash cube to be inserted and setting the shutter via linkage 4, 5. The rotation also brings a pin 34 in a slot 36 into alignment below the end of a lever 17. Depression of the control plunger 10 causes the pin 34 and hence a switch body 31, to be depressed, so that fingers 33 of the body 31 completely clear depending sections 26 of the holder 23. As the pin reaches a wider part 38 of the slot, the body 31 is spring urged to the right, (as seen), causing the fingers 33 to traverse the undersides of the sections 26. At this instant the shutter is opened via linkage 14, 3. The control plunger 10 is then allowed to rise, hence the body 31 is spring urged upwards and fingers 33 thereof engage inclined surfaces 27 of the section 26, thus rotating the holder 23 through 90 degrees. The flash cube may be left on the camera during daylight exposure, in which case part of the slide 6 can be dispensed with.

Filed: 1967-11-03
Abstract: 1,201,475. Stapling and nailing machines. FASTENER CORP. 3 Nov., 1967 [19 Dec., 1966], No. 50048/67. Heading B4C.  A pneumatically-actuated tool for driving fasteners, such as nails or staples, comprises a drive piston 2 reciprocably mounted in a cylinder 18 under the control of a main valve 20 and a control valve 25, and a pilot valve 24 for initiating the operation of the tool. The main valve 20 includes a diaphragm 40 adapted to normally close the open end 18a of the cylinder 18 by means of air supplied from a reservoir 16 via ports 82, 124, a passage 126 in a piston member 106 of the control valve 25, and a passage 48; the air above the piston is exhausted via a hollow valve member 50. In order to effect a drive stroke the pilot valve is operated so as to close the port 82, thereby exhausting the air acting on the diaphragm. Air in the reservoir 16 continually acting on the underside of the diaphragm 40 via a passage 46 then lifts the diaphragm and so allows the air to actuate the drive piston. At the end of the working stroke, the air opens a valve member 64 in the piston so that the air can then flow via a port 70 in the piston and ports 62 in the cylinder, into a return reservoir 60. At the same time the air acts on the piston control valve 106 moving it downwardly so as to thereby close the diaphragm main valve and exhaust the air above the drive piston so that it can return.
