Abstract: 1,226,271. Hydraulic motor control circuit. EATON YALE & TOWNE Inc. June 25, 1969 [July 5, 1968], No.32175/69. Heading F1P. A hydraulic motor control apparatus comprises a plurality of series arranged flow-paths between the motor 20 Fig.1 and a pump 12, said flow-paths being intercepted by flow control means e.g. spool valves 24, 26 which serve (a) to interconnect flow-paths 16, 60, 82 with 86, 62, 46 by means of a first by-pass 90, (b) to disconnect by-pass 90 as shown in Fig.2 and establish a first set of flow-paths 16, 60, 84, 106, 102, 96 and 100, 108, 112, 88, 62, 46 (c) to interrupt the first set of flow-paths as shown in Fig. 3 and connect flowpaths 16, 60, 84 with 88, 62, 46 by means of a second by-pass 92, (d) to disconnect the by-pass 92 as shown in Fig.4 and establish a second set of flow-paths 16, 60, 82, 102, 96 and 100, 108, 86, 62, 46 and (e) to re-establish the first by-pass 90 whilst interrupting the flow through the second set of flow-paths as shown in Fig .1. Valve 24 when moved to the left as shown in Fig.2 initiates a step of motor 20 and this step is terminated when valve 26 is moved to the right as shown in Fig.3 by a cam 114 secured to the motor shaft 116 thereby establishing flow through by-pass 92. To effect of further step of motor 20, valve 24 is moved to the left (see Fig.4) and the further step is terminated when portion 122 of cam 114 contacts rod 73 of valve 26 and allows the latter to be.displaced to the left by a spring 118 to the portion shown in Fig.1. Continuous operation of motor 20 is effected by moving a spool valve 22 from the position shown in Fig.1 to that shown in Fig. 5, valve 24 being in the Fig.2 position whilst valve 26 is held away from cam 114 by a solenoid 128. Means 132 for counting the number of steps during continuous operation comprises a magnetic pickup 134 positioned near the circumferance of a gear-wheel 136 attached to and driven by the motor shaft 116; the passage of each gear tooth in front of the pick-up corresponding to a single step of the motor and resulting in production of a voltage pulse. In a modification Fig.6 (not shown) the valve 22 is dispensed with and valve (26) has an extra operating position whereby the motor may either by stopped or continuously operated. In a still further modification Fig.7 (not shown) wherein the valve 22 is eliminated the two other valves have a reduced number of lands.

Abstract: 1,229,088. Automatic exchange systems. SIEMENS A.G. 1 Dec., 1969 [2 Dec., 1968], No. 58560/69. Heading H4K. In a system having a sectionalized network with an individual marker per section, at least some of the last-stage multiple switches in one section are duplicated having their inlets connected in parallel to those of their partner and having their outlets connected to the outlets of multiple switches in another section whereby increased accessibility is obtained. The Figure shows a two section network GRE1, GRE2 having individual markers M1, M2 wherein the inlets ell-eln, e21-e2n normally have access only to outlets 1a11- 1a1n, 1a21-1a2n respectively. A last stage switch such as 1D in section GRE is duplicated at 2D 1 whose inlets are in parallel with those of 1D1 but whose (second order) outlets 2a11 extend to the main (first order) outlets of a switch in the other section. During the setting- up of a connection, central control ST may find no free junctions VL in a wanted direction and directly accessible to a caller ES or, having found such a junction (by interrogating additional section control circuit VP1) it may happen that the section marker cannot find a path thereto. In either case, ST interrogates the control circuit VP2 of another section having the required direction junctions and which is multipled to the calling section. The result of the interrogation is passed to the calling section marker which then attempts to set-up a connection to one of the section's relevant second order outlets. The possibility of using more extra switches to provide higher order outlets and the question of unequal size sections are touched-on.

Abstract: 1,230,590. Controlling burners. THERM-O-DISC Inc. 2 Aug., 1968 [2 Aug., 1967; 30 Oct., 1967], No. 37068/68. Heading F4T. [Also in Division H1] The heat radiated by a gas burner assembly (e.g. for a clothes dryer) comprising a gas manifold 12 containing series connected solenoid valves 14 and 16 and a pressure regulator 13 and feeding a gas via an air register 21 to a burner tube 19 which projects into a funnel 31 and mounts a baffle 21 and a coil igniter 23 at its downstream end, is detected by a sensor 34 mounted on the funnel 31 and containing a U- shaped bimetallic switch member one of the arms of which is exposed to the heat radiated by the igniter 23 and/or the burner flame and the other arm of which is not exposed to said radiation. (See Division H1 for construction of sensor 34). The sensor 34 forms a switch 58 (see Fig. 3) in the ignition and control circuit 48 of the burner. The circuit 48 is connected to a power source via lines L 1  and L 2  which also feed power to a timer 43, a motor 46 powering the dryer and operating a fan 47 which draws air into the rearward end of funnel 31. Closure of the dryer door closes a switch 42 so that power is supplied to the timer 43 which then closes switches 44 and 49 to maintain the timer 43 operative and energize the motor 46. When the motor 46 reaches a predetermined speed it closes a centrfugal switch 51 to supply power to the circuit 48 (an overheat switch 52 being closed). Thus power is supplied via the switch 58, which shunts the solenoid 59 of valve 16, and via a switch 56 to the solenoid 53 of valve 14, which then picks up to change switch 56 over to a contact 61 (this switch contacting 61 prior to disengagement from contact 57), and also to the igniter 23. Valve 16, however, is not energized due to the shunting thereof by switch 58 and no gas is supplied to the burner. When the igniter reaches a predetermined temperature, e.g. 2300‹ F., the radiation omitted thereby causes the switch to open thus energizing solenoid 59 and reducing the current through igniter 23. Gas is thus supplied to the burner tube 19 and is ignited by igniter 23 which has a sufficient thermal mass to retain its high temperature long enough to ignite the gas. If ignition does not occur switch 58 closes since igniter 23 cools and does not emit sufficient radiant heat, and hence gas supply to the burner is cut off, the fan 47 still operating to purge the burner and the igniter being re-energized for a second attempt. At the end of a drying operation timer 43 opens switch 49 to terminate combustion. A thermostat switch may be included in the circuit adjacent switches 49-52.

Abstract: 1,232,566. Boring machines; gauging. BABCOCK & WILCOX CO. 20 Feb., 1969 [15 April, 1968], No. 9135/69. Headings B3B and B3C. Apparatus for finish-boring a workpiece comprises a boring bar which includes fluid pressure pockets for maintaining the boring bar in stable accurate relation to the workpieee. In one embodiment (Figs. 1 and 2) a boring bar 15 has a portion 16 adjacent the tool T formed with opposed pressure pads 17 each associated with a restrictor 18, the portion 16 being guided through a guide 22 having an accurate bore 23 whereby a film of pressure fluid is maintained between the surfaces of the portion 16 and the bore 23 to stabilize the tool T. Continued feed of the boring bar causes the pressure pads successively to enter the finished portion of the bore in the workpiece whereby similar co-operation of the surfaces of the portion 16 and workpiece bore stabilize the tool. In another embodiment (Figs. 4-7, not shown) some of the pressure pads (27, 28) may be supplied separately from the remainder (26) whereby the boring bar can be centred to withdraw the tool from the surface of the workpieee or can be operated eccentrically for boring. In another embodiment (Figs. 8, 9, not shown), fluid to one pad (36<SP>1</SP>) may be interrupted to withdraw the tool from the surface of the workpiece and in another similar embodiment (Fig. 10, not shown) the pressure of fluid to one of the pads (36<SP>1</SP>) may be decreased to effect such withdrawal. In other embodiments (Figs. 11 and 12, not shown) one pressure pad may have an auxiliary restrictor whereby pressure at that pad may be increased to effect tool withdrawal. In another embodiment (Fig. 13, not shown) some of the pads are used to detect tool wear and to raise an alarm when this exceeds a predetermined amount. In a similar embodiment (Figs. 15, 17, not shown) excessive tool wear is also detected and the tool retracted as a result. In another embodiment (Fig. 14, not shown) pressure differences across opposed pressure pads may cause rapid advance of the boring bar into the work to be stopped, or may cause retraction of the tool. In a further embodiment (Fig. 16, not shown) anticipated tool wear and its attendant results are compensated by a programmed feeding of fluid to the pressure pads to stabilize the tool. The pressure fluid may be that normally used to cool the workpiece and tool.

Abstract: 1,250,846. Telegraphy. C.I.T. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 5 March, 1969 [19 March, 1968], No. 11815/69. Heading H4P. A subscriber line equipment comprises a transistor circuit as shown branched off the receiving wire A and transmitting wire B of a telegraph line which may be isolated from automatic switching equipment by exchange contacts KA, KB of a cross-bar switch comprising other contacts KV, KF. The circuit shows following modes of operation. (a) When the line is at rest wire A is negative and B is earth. Transistors TA-TC are on and TD-TH are off, capacitor C 1  is charged, C 2  is discharged, and neon L is off. (b) When the line is called by a calling subscriber, wire A becomes positive. Consequently TD switches on, causing C 1  to discharge slowly. After a time tC 1  is discharged to such a level that TE switches on, so connecting terminal AP to earth to indicate to selection switches the presence of the call. The presence of C 1  prevents TE being switched on in response to a positive transient pulse on wire A. (c) When the call has been serviced, earth is applied to the equipment from holding wire V, via contact KV, this causing TA-TE to switch off, and consequently the calling condition at AP ceases and the circuit presents a high impedance to the line. Neon L switches on. (d) When the selection switches designate the equipment to receive they apply a negative potential to terminal DP to determined whether or not the line equipment is free. If it is, there is no earth at V and so the negative at DP passes to terminal LB to indicate that the equipment is free. On the other hand, if the equipment is not free there is earth at V, TF is on, and negative appears at terminal OC to indicate the busy condition. (e) Should there be a group of telegraph lines and associated line equipments the output OC of the first line equipment of the group is connected to input DP of the second, OC of the second to DP of the third, etc., so that when the selection switches call the group the first free equipment is found and busied, giving earth at wire V. (f) When the line equipment is used as called party equipment a call is represented by positive wire B. If the call is received by the called party wire A goes from negative to positive. If the call is not received wire F goes to earth so that TH switches on, as does TG. In consequence, neon L flashes repeatedly. Capacitor C 2  being charged, only a sufficiently long positive on wire A can unblock the equipment. (g) If the line emits no signal when the line equipment is calling, the call having been serviced, F is at earth and the equipment is blocked as in f above. However, wire A being positive TD, TE are on so C 2  cannot charge. Since TH is on the call at AP is suppressed. When A reverts to negative TD, TE switch off, C 2  charges, and the equipment can be subsequently unblocked by wire A going positive.
