Title: Improved rotary refrigerating machine
IPC: F25B3/00
Filed: 1928-10-29
Abstract: 299,724. Audiffren, M., and Singr³n, A. Oct. 28, 1927, [Convention date]. Piston pumps.-In compression refrigerating machines comprising coaxial rotary casings, the evaporated refrigerant returns from the evaporator casing 2, Fig. 1, to the compressor chamber 7 in the condenser casing 1, through a tube 14 located in the bore of the shaft 3, and flows through relatively short passages to the compressor suction, so as to avoid the tendency for the refrigerant to become heated before compression. The condensed refrigerant flows along the shaft passage 18 around the tube 14 to the evaporator. The shaft may be continued through the walls of both casings as shown, whereby a driving pulley or motor may be fitted directly to the shaft at either end or between the casings. The compressor comprises single or twin pistons 12, Fig. 3, oscillating about a point 43, and cylinders 11 reciprocated by an eccentric 13 formed on the shaft of the casings. The vapour passes from the axial tube 14 through radial and circumferential passages 15, 16 in the eccentric to the cylinder ports 17, and is discharged through flap valves 19 to the compressor casing. A modification is described in which the pistons are reciprocated by the eccentric; or a crank may be used. The compressor casing 7 is held stationary by a ballast weight 9, Fig. 3, and the refrigerant and lubricant pass through an opening 20, Fig. 1, in the casing 7 into the outer rotary casing 1, which is cooled. A scoop 22 on the casing 7 dips into the ring of liquid and delivers it into a stationary chamber 8 at the side of the compressor chamber, where most of the lubricant separates by gravity and floats through an opening 23 back to the compressor, while refrigerant flows through a pipe 24 to a further chamber defined by a partition 25 of the casing 1. By centrifugal action in this chamber lubricant is separated and led away at the centre, and condensed refrigerant is picked up by a scoop 27 on a stationary pipe 26 and led to the passage 18 and the evaporator. An annular mass 44a, freely mounted on the compressor casing or on the shaft, and provided with a slot 46, is engage able by yielding pins 47 on the compressor casing to prevent or stop swinging of the compressor casing.

Abstract: 488,524. Uniting by fusion: ELIN AKT. - GES, FUR ELEKTRISCHE INDUSTRIE. Nov. 15, 1937, No. 31400. Convention date, Nov. 14, 1936. [Class 83 (iv)] Flux coated arc welding electrodes are supplied with current and fed to the work by elements which engage previously bared spots on the electrode, spaced at any distance apart, the elements travelling with or engaging the electrode until within proximity of the arc, without melting. The electrodes may be of continuous form or may consist of rods connected together end to end, the spacing of the spots not being restricted to the points of interconnection of the rods. The bared ends of the rods may also be connected by metal sleeves which may be slotted to serve also as bared spots. The bared spots may be formed during manufacture of the electrodes or prior to introducing them into the welding machine or the cutting mechanism may be mounted on the welding head. In Fig. 4, a pair of milling cutters 6 are carried on and rotated by a motor 7 which is moved towards and from the electrode 1 by adjustable crank gears driven through gearing from the electrode feed motor 8 which may operate a feed screw 3. The cutter may also consist of a screw with serrations mounted in alignment with the feed screw. The two screwed spindles are replaceable. The electrode may also be supplied with current and fed by the threads of a hollow water-cooled copper-alloy feed-screw engaging the bared spots directly. In the form shown in Fig. 4, the feed elements consist of slotted plates 2, Fig. 2, which are fed by hand or automatically from a stack to engage slots on opposite sides of the electrode. The plates at each side brush between water-cooled current conducting-bars 4. The plates are stripped off the electrode 1 at 16 prior to them reaching the arc. The rods may be supplied with current and fed by spring-pressed members 12, Fig. 5, carried by an endless band, chain or cord, bending of the electrode being prevented by rollers 13 or by a similar band &c. arrangement on the other side of the electrode.

Title: Apparatus for detecting changes in the thickness of an ink film on the roller system of a printing press
Inventor: ADAMS JOHN MICHAEL
IPC: B41F33/00
Filed: 1966-07-13
Abstract: 1,140,107. Inking apparatus. RESEARCH ASSOCIATION FOR THE PAPER & BOARD, PRINTING & PACKAGING INDUSTRIES. 12 June, 1967 [13 July, 1966], No. 31402/66. Heading B6C. [Also in Divisions G1 and G3] Changes in the thickness of an ink film on the roller system of a printing press are detected by using a transparent roller 1, rotating in contact with one of the rollers 7 of the press inking system, to pick up an ink film therefrom, and photo-electrically measuring the thickness of this picked-up film. A photo-conductive cell 16 mounted inside the roller 1 receives light from a lamp 17 through the surface of the roller. The light is attenuated in accordance with the thickness of the ink film, which is directly dependent on the film thickness on roller 7. The cell 16 is connected in a Wheatstone bridge circuit, Fig. 2 (not shown) with a balancing photoconductive cell 19 which receives light direct from lamp 17 and thus monitors changes in the lamp intensity. A microammeter (37) senses out-of-balance current in the bridge circuit and has a shunt capacitor to damp the meter and keep its response time longer than one revolution of the roller 1. This prevents marks on the roller surface from causing a meter response. A potentiometric recorder (41) may be used to record variations in the bridge current with time. In setting up the apparatus, the press is run until the ink film thickness on rollers 7, 9 is correct, as judged from visual examination of prints taken. The bridge is then balanced to zero the meter by adjustment of a diaphragm 20 in front of cell 19. Any out-of-balance thereafter results from deviations from the correct film thickness and a warning light or audible alarm may be incorporated in the circuit to indicate such deviations. The ink flow from the duct may be controlled using the bridge output. A number of cells 16 or pairs of cells 16, 19 may be mounted along the axis inside the roller 1 and a long tubular lamp 17 used for illumination, respective bridge and meter channels and a multi-channel recorder being provided.
