Abstract: 653,179. Chain saws. ALEXANDER, H. J., and TELES SMITH, Ltd. March 12, 1948, No. 7566. [Class 145(ii)] A machine for ripping timber comprises horizontal rods positionable on either side of the lying timber on which runs a wheeled carriage provided at each side of the timber with vertical guides means, a stage on each of said guide means for supporting one end of a chain-saw unit and means for vertically adjusting the stages together. The machine comprises horizontal chassis members 8 having grooved wheels 9 which run on rails 1 mounted on sleepers 1a. Each member 8 has a pair of vertical guides 10 mounted on it which are braced at their upper ends by a spanning frame 11. Mounted between the guides are stages 12, 13, the stage 12 carrying the motor unit of a motor driven chain-saw and the stage 13 carrying the chain wheel housing at the other end of the saw. The stages may be raised or lowered simultaneously by cable 17, 18 anchored to drums 11b, 11c which are mounted on a shaft 11a, bushed in spanning member 11, and rotated by a handwheel 19. A rachet and pawl .mechanism 20 is fixed to the shaft for checking counter rotation. The carriage is moved longitudinally to feed the saw into the log by cables 21 anchored to drums 5 which are mounted on a shaft 4, bushed in strutting posts 3, and rotated by a handwheel 6. The shaft 4 is provided with a ratchet and pawl 7. Several interchangeable ratchets may be fitted at 20, each having differently spaced teeth to vary the thickness of the plank cut. Racks and pinions may .be fitted for the longitudinal and vertical adjustments of the stage instead of cables, and the vertical adjustment may be made with linear ratchet racks and pawls. Specification 638,217 is referred to.

Title: Improved refrigerator
IPC: F25B43/02
Filed: 1958-03-14
Abstract: 818,788. Refrigerating. OPEL A. G., A. March 14, 1958 [March 28, 1957], No. 8254/58. Class 29 A refrigerator includes a motor compressor unit, an oil separator connected to the compressor outlet and through a valve in an oil return passage to the compressor inlet and a control device operative to open the valve in the passage during motor starting periods. Compressed refrigerant enters the separator through pipe 10, flows through a heat exchange coil 12 and is discharged against a baffle 14 where the oil separates from the refrigerant settling in the bottom of the separator. The oil supports a float 18 carrying a soft iron plate 20 which can cause a lever 23 bearing a magnet 22 at one end to tilt thus closing the contacts 25, 26 of a switch. Contact 26 is connected to terminal U of the power supply and contact 25 is connected to terminal V through the solenoid 28 of a valve in the oil discharge line 29 to the compressor inlet. Armature 43 of coil 42 operates switches 44, 45 so that when one is opened the other is closed. Switch 44 is in series with a heater 40 and valve solenoid 28 and is in parallel with the contacts 24, 25. Switch 45 connects coil 42 across the power supply and there is a bimetallic thermal switch 41, acted on by the heater 40 in parallel with switch 45. While the compressor is in operation the float 18 controls the oil level in the separator by acting on contacts 25, 26, causing energization of solenoid 28 and opening of the valve to allow discharge of oil to the compressor inlet. On starting the compressor motor the switches 41, 44, 45 are in the position shown and current flows through heater 40 and solenoid 28 opening the valve in line 29 and lightening the initial load on the compressor. Heater 40 then closes the thermal switch 41 energizing the coil 42 opening switch 44 and closing switch 45 which keeps the coil 42 energized until the compressor motor is switched off.

Title: Rotary internal combustion engines
IPC: F02B75/02
Filed: 1951-04-10
Abstract: 687,706. Rotary engines. SHORE, B. May 30, 1951 [April 10, 1951], No. 8264/51. Class 110(ii) [Also in Group XXVIII] A rotary internal-combustion engine has a rotor 1, provided with vanes 22 which co-act with abutments 7, 25, 24 which are lifted by external cam gears 40, 41, 42. Side plates 37, on the stator 3, allow easy access to the abutments. Combustible mixture, controlled by an induction abutment, is supplied from a chamber 18 through ducts 17, 16 to a chamber 4 and compressed by a vane 22 through ducts 20, 34 into a transfer chamber 21. Firing and sealing abutments 25, 24 are lifted at different times to allow the passage underneath of a vane 22, and compressed mixture, under control of a rotary sleeve valve 33, passes through ducts 27, 26, 30 into combustion chambers 28 where it is fired by a plug held in a socket 31. In the case of a compression-ignition engine, an oil injector replaces the plug in the socket 31, and air only is compressed into the chamber 21. Rotation of the valve 33 is effected by movement of the abutment 24 through link mechanism 35. Exhaust gases pass through an outlet 32. A pair of annular side plates 36 are bolted to the stator sides and seal off the working chamber. External springs 12 press down the abutments on to the rotor periphery. Shoulders 10 limit the inward movements of the abutments. Sealing strips 19, 23, in abutment and vane respectively, are of T-section, Fig. 6, and constructed of pieces having co-acting inclined surfaces 50, 51. Springs 52, having adjustable plugs 54, press upon the strips. The strips 23 are set at an angle across the face of each vane to avoid tripping when passing other sealing strips or ports in the stator. The abutment spindles 11 are provided with plungers 57, in cylinders 58, into which lubricating oil is fed through a pair of ducts 61. A throttle screw 66 is placed as shown. Lubricant is forced through bores 65, 64, 67, 68, 69, 70 when the plungers are reciprocated. In an alternative arrangement, when used as a compression-ignition engine, the charge from the compression chamber 4 is passed to an external supercharger for further compression, before being transferred to the firing chambers 28.

Filed: 1955-03-22
Abstract: Petroleum distillates are autofined twice, the pressure in the first autofining being below the equilibrium autofining pressure. The distillate from the first stage may either be recycled or reprocessed over fresh catalyst.  The catalyst may be the oxides of cobalt and molybdenum either as such or in combined form incorporated with a metal oxide support, such as alumina, and may contain a small proportion, e.g. 0.1-6 per cent, of combined fluorine.  In an example, gas oil is autofined at a temperature of 780 DEG  F., a pressure of 100 p.s.i.g., a space velocity of 2 v./v./hr. and a recycle rate of 2000 SCF/B.  The product is washed with caustic soda and water and then reprocessed under the same conditions over fresh catalyst.  Specifications 654,152, 663,038, 669,536, 669,552, 669,553, 697,083, 697,222, 697,226, 697,724 and 719,627 are referred to.

Abstract: 682,539. Moulding packing rings of plastic material. LEVITATION, Ltd. April 3, 1951 [April 3, 1950], No. 8308/50. Class 87 (ii). A mould for articles of resilient plastic material, e.g. packing rings of nylon, comprises three parts 13, 14, 16, a portion 11 of the article, perpendicular to the parting plane of the mould, being formed between the mould parts 14, 16, one of which is shaped to form grooves &c. on this portion of the article. The mould also comprises a plunger 21 and an annular ejector 25 both connected to a metal plate 23. After the injected material has set, the parts 13, 14 are moved away from each other, Fig. 2, (not shown), thus releasing the grooved portion 11 of the article from the annular flange 17 on the outer mould part 14. Movement of the plate 23 now causes the ring 25 and plunger 21 to force the article off the inner mould part 16, the grooved flange 11 being free to expand radially and to disengage itself. The moulding is finished by removing the plug 30 and the diaphragm which connects it to the moulded ring.

Heating temperatures up to 400 DEG  F. are specified and the heating medium may be saturated steam under pressure.  An initial alkali treatment may be with sodium hydroxide, soda ash, borax, sodium silicate, trisodium phosphate or mixtures thereof.  The peroxygen compound may be hydrogen peroxide, an alkali metal percarbonate, perborate or phosphate perhydrate, peracetic acid or performic acid or their salts, and the aqueous solution thereof, at a pH of 10 to 11.5, may contain one of the previously mentioned alkalis and/or a wetting agent, examples of which include various sulphonated organic compounds, ethylene oxide condensates, alkylolamine condensates and soap.  The materials treated include grey goods and goods which have been scoured, soured, desized or boiled, and may be of cotton or linen.  Goods in long length may be treated in a continuous process.
