Title: Pistons for Internal COmbustion Engines
Inventor: DOLENC ANTON
IPC: F16J1/24
Filed: 1968-09-04
Abstract: 1,169,326. Pistons; connecting-rods. SULZER BROS. Ltd. 4 Sept., 1968 [26 Oct., 1967], No. 42085/68. Heading F2T. A piston and connecting-rod assembly for an internal combustion engine comprises an indexing member 8<SP>1</SP>, Fig. 1, coupled to the rod 5 so that pivotal oscillation of the rod relative to the piston 1 produces rotary oscillation of the member, co-operating friction surfaces on the member and piston respectively and means whereby, in operation, a force derived from a source other than the pivotal movement of the rod is applied intermittently to frictionally engage and release the friction surfaces in phase with reciprocating movements of the piston which is thereby progressively rotated about its axis. The rod 5 has a ball end 4 housed in a spherical bearing 2, 3 and carrying an inclined pin 14 whose ends engage between two pairs of lugs 13 on the indexing member 8<SP>1</SP>. A thrust member 10 is located with the member 8<SP>1</SP> with axial clearance in a recess in a ring 7 secured to the piston by bolts 8. A screw 12 threaded in the ring 7 projects into a groove 11 in the member 10. In operation, when the inertia force of the member 10 acts to clamp the member 8<SP>1</SP> against the ring 7 the piston rotates with member 8<SP>1</SP>. When the inertia force acts in the opposite direction member 8<SP>1</SP> rotates freely in the ring 7. In a modification. Fig. 2 (not shown) the inertia effect of the thrust member (27) is augmented by the inertia effect of the cooling oil in the piston head cavity (20) which communicates through bores (19) with a groove (18) slidably housing the thrust member. In a further modification. Fig. 3, a thrust member 37 is urged against the indexing member 36 by the pressure of lubricating oil supplied through bores 42, 43 in the rod 39 and a groove 45 and a bore 49 in the piston 31 to an annular groove 49 slidably housing the member 37; the flow of oil being controlled by the pivotal movement of the rod 39. In the modification shown in Fig. 5, the indexing member 66 has a spherical bearing surface 67 for the ball head 62 and a conical friction surface 68 co-operating with a friction surface 69 on a part 70 secured to the piston 61. The friction surfaces 68, 69 are loaded by the inertia of the piston when it is in the vicinity of top dead centre. In another modification, Fig. 7 (not shown), the inclined pin (86) has only one end engaging a notch (87) in the indexing member (88) which has a conical friction surface (89) co-operating with a complementary surface (90) in a member (84) and a thrust bearing (91) is interposed between the member (88) and the piston (81).

Title: Compressor Control in Refrigeration Systems.
IPC: F04B49/24
Filed: 1967-09-20
Abstract: 1,194,266. Valves. CARRIER CORP. 20 Sept., 1967 [3 Oct., 1966], No. 42877/67. Heading F2V. [Also in Divisions F1 and F4] A refrigeration system includes a valve 10 which opens to allow refrigerant to flow from the discharge to the suction side of compressor 12 when the pressure difference across the compressor reaches a predetermined high or low value. The valve includes a casing 25 having openings 28, 34 communicating with the suction and discharge sides of compressor 12 respectively, a piston 45 having a port 48 therethrough, a spring 49 urging the piston towards wall 33 of the casing, a valve member 60 for controlling flow through the port, and a spring 65 urging the valve member 60 towards the piston. Member 60 has a stem 63 which extends through an opening 53 in the piston and is of such a length that when valve member 60 engages its seat 50 the end of stem 63 projects beyond the face of the piston. When the compressor is shut down and its inlet and outlet pressures substantially equal, the piston is pressed against wall 33 and valve member 60 opens port 48 because of engagement of stem 63 and wall 33. At start-up the pressure difference slowly increases and piston 45 is moved to the left, eventually engaging valve member 60 to close port 48. The pressure difference then rises rapidly and piston and valve together move to the left. If the pressure difference becomes too high, the piston engages a stop 47 and member 60 continues to move to the left to open port 48. When the compressor is shut down, the pressure difference falls and piston and valve move to the right until at a predetermined pressure stem 63 engages wall 33 and further movement of the piston opens port 48 to equalize the pressures.

Abstract: 1,019,517. Melt spinning synthetic filaments. CHEMIEFASERWERK SCHWARZO WILHELM PIECK VEB. Nov. 15, 1962, No. 43269/62. Heading B5B. In the process of melt spinning synthetic filaments in which the molten filaments from the spinneret are cooled and solidified by passing them in a generally vertical downward direction through a spinning cell in which a non- turbulent stream of a cooling gas or vapour is directed laterally on to the filaments, the stream of gas or vapour has a temperature of 15‹ to 30‹ C., and a relative humidity of 50 to 90% and the stream of gas or vapour impinging on the filaments is inclined downwardly from the horizontal in the direction of its flow at an angle of between 10 and 30 degrees. As illustrated in Fig. 1 (not shown) an apparatus for cooling and solidifying the filaments according to the invention comprises a three-way valve 1 for controlling the rate of flow of the gaseous cooling medium, e.g. air, into the blow box or plenum chamber 4 through an entry tube 2 and a filter or diffuser system 3. The wall between the blow box 4 and the spinning cell 11 through which the melt spun filaments travel downwards and in which they are cooled and solidified comprises an assembly of superimposed layers of fine wire gauze or perforated metal sheets 5 and a honeycomb-like nest of short tubes 6 through which the cooling medium from the blow box 4 is impelled into the filament spinning chamber in a diffused but substantially straight line flow free from turbulence so that the cooling gas contacts laterally the downward travelling streams of polymer. The direction of the gas flow is downwardly inclined from the horizontal at an angle to the path of filament travel, the path of the cooling medium being, for example, inclined at an angle of 15 to 25 degrees to the horizontal. The spinning chamber comprises two solid vertical side walls 7 (Fig. 2, not shown), which are curved in such a manner as to contribute to the non-turbulence of the flow of cooling gas.
