Title: Turbine driven compressors
IPC: F04D29/14
Filed: 1957-12-20
Abstract: 875,319. Centrifugal compressors; stuffing- box substitutes. GARRETT CORPORATION. Dec. 20, 1957 [Dec. 21, 1956], No. 8321/61. Divided out of 875,318. Classes 110 (1) and 122 (5). A refrigerant compressor having an impeller 10 and a driving turbine 11 on a common shaft 12 comprises a shaft seal comprising an axially movable non-rotatable valve ring 41 which, when the compressor is at rest, is urged by a spring 45 into sealing contact with a seat 40 on a ring 35 secured to the shaft 12 and is moved out of engagement with the seat 40 by means actuated by turbine motive fluid when motive fluid is admitted to the turbine. The valve ring 41, which may be of moulded plastic, is mounted on one end of a piston 42 slidable in a cylinder 47 and sealed to the impeller housing 15 by a flexible diaphragm 43. When the compressor is started turbine motive fluid passes from the turbine inlet 57 through gap 59, space 52 and passages 51 and 50 into space 46 to move the piston 42 to the left and retract the valve ring 41 from its seat 40. A spring-loaded ball valve 54 in the passage 51 delays the drop in pressure in space 46 when the turbine is shut off to prevent seating of the valve ring 41 whilst the compressor is coasting to a stop. The shaft is sealed when the compressor is running by a carbon ring 36 in fluid rubbing sealing contact with the ring 35; this seal also assists to prevent leakage when the compressor is at rest. The impeller 10 is sealed to the housing 15 by labyrinth seals 25 and 30.

Title: Curve milling or curve grinding machines
IPC: B23Q15/00
Filed: 1972-02-23
Abstract: 1354256 Copy-milling and grinding machines MASCHINENFABRIK ALFRED SCHMERMUND 23 Feb 1972 [3 March 1971] 8348/72 Headings B3K and B3D In a curve milling or grinding machine for forming cam discs or cylinders, a displaceable tool support 10, having a tool 76 rotated by motor 18, is displaceable coupled to a sensor 26 which follows the contours of a template 24 translatable by means of a stepping motor 45. The scale of copying may be adjusted by moving link 22 on sensor 26. Angular movement of a workpiece support spindle 30 rotated by motor 34 produces, by means of a signal generator 36 coupled thereto, a series of pulses corresponding in number to the amount of angular movement. The pulses are divided by frequency dividers 40-43, are counted by counter 38 and passed on to the stepping motor 45 which moves in response to the pulses. The radial variation of the cam profile is thereby controlled by the template and the angular variation by the setting of the dividing factors. A particular disc cam profile to be produced has four portions, a dwell, a fall, a further dwell and a rise, the angular extent of each of which being by and is dependent on the dividing factor of the corresponding divider 40-43. After each portion is formed, counter 38 reaches a predetermined number, resets, and operates switch 44 which switches to the next divider. The workpiece rotates once in the whole operation. The rise and fall portions are formed by corresponding forward and reverse movements of the template but the motor 45 is stopped when forming the dwell portions. A fifth divider may be provided which permits the forming of a spiral cam when the template is constructed as a simple triangle. The signal generator frequency dividers and the counter may be electrically, pneumatically or hydraulically operated.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T8/32
Filed: 1961-03-08
Abstract: 960,262. Fluid-pressure brakes. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. March 8, 1961 [March 9, 1960], No. 8414/61. Heading F2F. In a compressed air or vacuum braking system for a rail or other vehicle, employing a brake cylinder having two chambers separated by a piston whereby braking force is dependent upon the pressure difference between the chambers, skidding of the vehicle wheels is prevented by means whereby an inertia or other device responsive to wheel locking is adapted to cause the two chambers of the cylinder to be connected together to equalize pressures therein, and the cylinder at the same time to be closed to atmosphere so as to prevent loss of pressure or vacuum therein. As shown, cylinder 14 is operated by compressed air supplied by a triple valve (not shown) via pipe 12, normally open valve 8 and pipe 13 to one chamber 115 of the cylinder, the other chamber 16 on the opposite side of the piston 15 being normally open to atmosphere via a valve 26. The valve 8 in its normal position closes a connection 17 between the chambers 115 and 16. Diaphragms 5, 23 respectively, operate the valves 8, 26. The diaphragm 5 is arranged in a chamber 50, the portion above the diaphragm being connected via a pipe 20 and a constriction 20<SP>1</SP> to the brake pipe 18 and the portion below the diaphragm being also connected with the brake pipe via a constriction 19 larger than the constriction 20<SP>1</SP>. Since the pressures above and below the diaphragm are normally equal springs 6, 9 are provided to maintain valve 8 in its normal position. Diaphragm 23 is arranged in a chamber, the lower part of which is connected to the constriction 20<SP>1</SP> by a pipe 21, the upper part being open to atmosphere so that the pressure in the brake pipe acts against springs 24, 28 to maintain valve 26 normally open. An inertia device 1 rotating with the vehicle wheel acts on a valve 2 so as to open the pipes 20, 21 to atmosphere when the wheel skids. This causes valve 26 to close, shutting off chamber 16 from atmosphere, at the same time causing valve 8 to move to shut off the supply of air from the pipe 12 while opening the connection 17 between the chambers 115, 16 to equalize the pressures therein. The constriction 19 causes valve 8 to move sufficiently slowly for the pressures in chambers 115, 16 to be substantially equal to the pressure in pipe 12 when the valve 8 has shut, so that when the wheel stops skidding and valves 8 and 26 return to their normal positions full braking is quickly restored. The inertia device 1 may operate the valve 2 via electric contacts and a solenoid, instead of mechanically, as shown.

Abstract: 1376024 Separating olefines UNION CARBIDE CORP 24 Feb 1972 [25 Feb 1971] 8519/72 Heading B1L In a process for the separation of straightchain mono olefines from branched-chain mono olefines using a molecular sieve pore diameter of about 5 in which the straight chain hydrocarbon is preferentially absorbed and would tend to polymerise the sieve is first loaded with a straight chain paraffin so that the heat of absorption is balanced by the heat of desorption of the paraffin and polymerisation is minimised. The first effluent in the process is a mixture of paraffin and branch-chain olefine from which the olefine can be separated. The sieve is then co-purged with a paraffin to displace the branch-chain olefine and then countercurrent purged with paraffin to desorb the straight chain olefine end to give a mixture of paraffin and olefine from which the olefine is separated. The separation of n-butene and isobutene is exemplified.

Abstract: 1,031,423. Automatic tape players. WURLITZER CO. March 5, 1963, No. 8750/63. Heading G5R. A tape 32, Fig. 3, carrying a plurality of recordings starting together on adjacent tracks, is played and rewound automatically to give the effect of a juke-box, the same motor driving the tape and the control means. A selector and coin-freed mechanism (not described) feed the requisite number of pulses to means 58, 60, 64, 70 to raise the head 38 to a selected track. The motor 48 drives through a solenoidactuated dog-clutch 252, 258 a cam-shaft 92, Figs. 13-15, which moves cyclically from one position to the next on receipt of starting signals and does one complete rotation for each playing. The cam-shaft is indexed by contacts (circuit, Fig. 16, not shown) operated by lever 278 so as to stop when the lever falls into steps in the cam 280. The cam-shaft moves from Fig. 13 to Fig. 14 to start playing. Follower 122 drops into dwell 190 to engage the capstan and head pressure pad (Figs. 2-4, not shown) and cam 246 releases the brakes 222, Fig. 3, from the reels. At the end of each playing, a tone-burst outside the audio-frequency band is picked up by the head 38 and fed through a tuned filter (not described) to start up the cam-shaft 92. The cam-lobe 244 momentarily applies the brakes; after release the cam 130 raises the shaft 94, Fig. 3, to engage a friction drive (Figs. 4, 5, not shown) to rewind the tape on to the reel 34. Since the recordings are of unequal lengths, cams Fig. 17, are driven forwardly during play and backwardly during rewind; when rewind is complete, the dwells 354, 356 align and the drives are disconnected and the brakes applied. A solenoid-actuated latch (Figs. 10-12, not shown) also releases the head 38 in readiness for a further selection.
