Title: Gas and liquid separator
Inventor: JENNINGS IRVING CALLENDER
IPC: B01D19/00
Filed: 1970-10-02
Abstract: 1284347 Centrifugal separator I C JENNINGS 2 Oct 1970 [9 Jan 1970] 46996/70 Heading B2P A separator for separating the liquid and gaseous components of a fluid stream comprises a cylindrical tank 11, an inlet pipe 12 for radially introducing the fluid stream into the tank and a baffle 17 mounted in the tank for changing the flow path of the radially introduced fluid stream to substantially tangentially strike the interior wall surface 18 of the tank whereby the fluid stream flows around the wall surface thereby causing the liquid and gaseous components to become separated, the components being removed from the separator through separate outlets 13, 14. Plate portions 19, 20 may extend between the upper and lower ends of the plate 17 and the tank wall 18 to form a channel for confining the incoming fluid stream to a narrow path around the separator wall surface. The channel may be inclined downwardly. A shelf 21 extends outwardly from the top 19 of the baffle to prevent liquid particles being blown up from the top of the channel. The separated liquid is removed through a drain 14 and a trap 15 which includes a float-operated valve 16 for preventing escape of gas.

Abstract: 1,072,396. Rock drills. SIBIRSKY GOSUDARSTVENNY PROEKTNO-KONSTRUKTORSKY EXPERIMENTALNY INSTITUTE MASHINOSTROENIYA. Dec. 3, 1963, No. 47610/63. Heading B3C. A rock drill comprises an hydraulic feed cylinder 3, Fig. 1, for drill 6, the cylinder also transmitting torque to the drill. The cylinder is rotated by an electric motor 1 through a reduction gear 2 and a piston 4 connected to the drill, slides in a square bore in the cylinder, and is rotated thereby. Fluid is supplied to the ends of cylinder 3 for feeding the drill by a distributer 9, and also through a channel 11 in rod 5, for flushing the drilled hole. In a modification, Fig. 4 (not shown), the drill is releasably clamped by identical clamps (17) and (18). Clamp 17 comprises a piston (19) which moves in a direction normal to the drill axis. Inside piston (19) is a clamping sleeve (21), having a trapezoidal bore which surrounds rod (5). In operation, fluid passes on to the top of the piston (19), which moves downwardly to clamp rod (5). Clamp (18) is unclamped and the drill is fed. After the drilling is completed, clamp (18) is actuated, clamp (17) is released, and piston (4) is retracted to its initial position. A shank (26) is detached to allow splicing of the drilling rods. To dismount the drilling rods, sleeves (27), (28) which mesh wire clamping sleeves (21), (22), are rotated, to rotate the latter through 180 degrees, so as to reverse the action of the clamps.

Title: Method and apparatus for error correction in a digital data transmission system
IPC: H04L1/00
Filed: 1974-11-05
Abstract: 1492388 Delta modulation; error correction GENERAL ELECTRIC CO 5 Nov 1974 [19 Nov 1973] 47711/74 Headings H3H and H4P In a delta modulation transmission system with companding characteristic, sync words and update words representing the size of the incremental steps are inserted into the delta-encoded bit stream, the delta-encoded signal being delayed and stored in a register 8, Fig. 1, while the inserted word is transmitted, and then transmitted, progressing by a plurality of steps from the most delayed bit to the least delayed in such a manner that no deltaencoded data is lost. Transmitter, Fig. 1.-Update words, obtained by gating out the state of the companding counter (not shown) of the encoder are inserted into the deltaencoded bit stream at predetermined clock instants between sync. words, under the control of logic 18. The word to be inserted is parallel-dumped into a register 16 and serially read out via selector 12. The delta-encoded bit stream is continually loaded into shift register 8, which becomes full at the end of the transmission of an inserted word. Logic 18 then switches over selector 12 and jump circuit 10 reads out the bits stored in register 8 beginning with the most delayed and jumping to the next stage after a predetermined number of bit times, encoding being interrupted for one bit time each time the jump circuit jumps so that register 8 is progressively emptied ready to accept delta-encoded bit stream when the next inserted word is being sent. A sync. guard 44 detects whenever the delta-encoded bit stream resembles the sync word and substitutes another word in its place. A voice operated switch 78 initiates immediate sending of a vox sync word (differing from a normal sync word in 1 bit) followed by an update word before transmission of the delta-encoded bit stream begins. Details are described with reference to Figs. 2-6, not shown. Receiver, Fig. 7.-The received bit stream is fed to a register 50. When logic 56 detects that the register holds a sync word counter 62 is reset and at predetermined counts thereafter, corresponding to times when update words should appear, transfer gate 68 is enabled to parallel-dump the update word into the decoder to adjust its increment step size, provided guard bit and parity checks, 58, 60 are satisfied. Register 50 is then empty and jump circuit 52, beginning at the least delayed stage of the register, jumps from stage to stage at a predetermined multiple of the bit time, decoding being interrupted for one bit time each time the jump circuit 52 jumps so that register 50 is progressively filled, becoming full when the next sync or update word appears. Vox sync detector 72 resets counter 62 and initiates an immediate transfer of the following update word, counter 74 allowing time for this to be loaded into the register 50.
