Abstract: 1,063,266. Machine tool details. BROWN & WARD (TOOLS) Ltd. June 22, 1964 [March 23, 1963], No. 11608/63. Headings B3B and B3T. A bar stock feed comprises a bar guide, formed in members (10) (12), a feed device (15), and a steady (41) coaxial with the guide, the steady having jaws (46) biased towards the bar (61). Members (10) and (12) have semicircular grooves 11, 13 therein to form the bar guide, and feed device (15) comprises a rod (17) movable in the guide by a member which passes through a gap (16) between members (10) and (12). Sprockets (24) reciprocate device (15) through a chain (23) having a pin (25) located in a slot (26) in the device, and limit switches (27) and (27a) are provided to cause a slow approach feed and a fast retraction. Device (15) has an abutment (29) which coacts with ears (30), (31) on a lever (32) pivoted to a rod (33), the latter also being pivoted to arms (34) which in turn are pivoted to levers. Arms (34) are connected to members (12) so that an abutment (29) coacts with ear (30), rod (33) moves to withdraw the means and allow a bar (19) to drop into groove (11). Simultaneously the cam levers move holding means (35) to prevent the remaining bars (19) from dropping. A rotary tube (37) is arranged coaxial with the bar guide and is supported in a bracket (38), so that its end (39) is spaced from the lathe spindle (40) a steady (41) is secured to the tube and comprises a sleeve (43), secured to the tube at (44) and jaws (46) guided in slots in a flange (45) provided on the sleeve.

Title: New amidine salts
Inventor: SUTER HANS
Filed: 1953-04-27
Abstract: The invention comprises amidine salts of the formula <FORM:0737035/IV (b)/1> wherein R1 represents a straight-chain or branched-chain alkyl residue containing at least two carbon atoms, X represents an oxygen atom, a sulphur atom, an -NH- group or a methylene group which can also contain alkyl residues, and R2 represents the anion of p-amino-salicylic acid.  Such salts are obtained by reacting amidines, guanidines or alkyliso (thio) ureas with p-amino-salicylic acid in a solvent or in water or by reacting inorganic acid salts of the amidines with salts of p-aminosalicylic acid with bases. Examples describe the preparation of the corresponding p-aminosalicylates by reacting (1) tri-n-butylacetamidine and p-amino-salicylic acid; (2) lauramidine hydrochloride and sodium p-aminosalicylate; (3) dodecylguanidine hydrobromide and sodium p-aminosalicylate; (4) 2,2,2-tributylethylguanidine and p-aminosalicylic acid.  In analogous manner there can be produced the p-aminosalicylates of triethylacetamidine, tripropylacetamidine, n-decyl-, n-undecyl-, hexyl-, n-cetyl- and tert.-decyl guanidines, O-isopropyl-, O-n-butyl-, O-n-hexyl-, O-n-octyl-, O-n-decyl-, O-n-undecyl-, O-n-dodecyl- and O-n-cetyl-isoureas and S-n-butyl-, S-n-decyl- and S-n-cetylisothioureas.

Abstract: 1333863 Air and vacuum pumps ITT INDUSTRIES Inc 13 Jan 1971 [21 Jan 1970] 1662/71 Heading F1N A reciprocating air compressor, or vacuum pump, is driven by a motor 30 having a fan 34 which draws in cooling air through cylinder head ports 24, the air flowing from the ports 24 through channels 26 surrounding the pumping chamber 72 before discharging through outlet vents 28. The pumping chamber 72 is variable in volume by a piston 48 sealed to a cylinder 50 by a flexible diaphragm (64) and driven by a rod 42 reciprocated by an eccentric 46. When operating as a compressor, air enters the cylinder 50 beneath the piston 48 through a filter 85 and flows through passages 60 into a cavity containing noise absorbing cellular material 62 such as soft plastics, elastomers, cellulose or expanded rubber. During the suction stroke the air passes into the pumping chamber 72 through a valve controlled opening in the piston. The compressed air is delivered past a valve 76 into a discharge 78 in the cylinder head. A cylinder head provided with valve controlled inlet and outlet chambers is fitted when vacuum pump operation is required, the opening in the piston being sealed. When the machine is a vacuum pump the piston is valveless.

Title: Telephone line control circuits
IPC: H04M9/00
Filed: 1975-03-24
Abstract: 1503792 Key telephone systems WESTERN ELECTRIC CO Inc 24 March 1975 [29 March 1974] 12246/75 Heading H4K Each line of a key telephone system is provided with a line control circuit including a counter which is energized for certain changes of state of the system to effectively provide a persistence check for the change of state. On detection of ringing current on the line the counter is fed with 20 Hz pulses. If a count of 6 is reached an output from the counter in association with a ringing present signal causes logic circuitry to respond to enable a tone generator (Fig. 3, not shown) and a "flash" signal generator to supply ringing tone and lamp flash signals to each key telephone of the system, the counter being reset. On termination of the ringing current i.e. due to the silent interval or calling party release, the counter is fed with 1Hz pulses. The tone generator is also disabled but the signal generator is held operative. If ringing current is again detected before the counter reaches a count of 12, (this will normally occur at about a count of 9 if the pause was due to the silent interval) 20 Hz pulses are fed to the counter and when a count of 12 is reached the logic circuit responds to the counter output and the ringing present signal to re-energize the tone generator, the counter being reset. If the counter reaches a count of 14 due to the 1 Hz pulses without ringing current again being detected, the circuitry is reset to idle. If a subscriber presses a hold button during a call the counter is pulsed at 60 Hz until a count of 3 is attained. The logic circuitry responds to place the line on hold and to energize a "wink" signal generator, the counter being reset. If line current ceases during a hold condition the counter is pulsed at 20 Hz. If the current is restored before a count of 9 is reached the counter is reset. The attainment of a count of 9 is recognized as a holding party release condition and the control circuit resets to return the hold line to idle. When the subscriber again presses the hold button to re-access a held line the counter is fed with 20 Hz pulses, attainment of a count of 4 causing the hold condition to be removed. The control circuit is described in detail with respect to Figs. 4-8 (not shown) and employs diodes, transistors, integrated circuits and a varister. The key telephones may be of known form utilizing LED's as the line condition indicators.

The comparator of Fig. 3, for example has pistons 101, 101<SP>1</SP> responsive respectively to the signals in lines 34, 35, and 44, 45. Signals 34, 44 indicate the positions of the second stage spools of valves 30, 40 whereas signals 35, 45 indicate the return pressures.
