Abstract: 1283347 Hydraulic motor control circuit DOWTY MINING EQUIPMENT Ltd 31 Oct 1969 [21 Nov 1968] 55321/68 Heading F1P A hydraulic motor (not shown) requiring a sudden high flow input is supplied through a service line 6 by a pump 1 provided with snap-acting unloaden means 3 having a first position shown in which pump delivery is connected to line 6 and having a second position in which pump delivery is cut-off from line 6 and unloaded to a resevoir 7; the unloader means 3 being moved to its second unloading position by a pressure sensing device 4 responsive to a predetermined high-pressure in line 6 and being moved to its first position when pressure in line 6 is below a predetermined intermediate value below which value the service line 6 is also connected through a pilot valve 9 to an accummulator 8 which latter is isolated from line 6 at high-pressures therein; line pressures between the intermediate and high levels having no effect on the unloader position and accumulator connection. As shown the pilot valve 9 is spring- biased to its closed position and is opened by pressure in a branch line 11 of the pump delivery line 2. In a modification Fig.3 (not shown) the pilot valve is biased to its open position and is closed by pressure in a branch line of the service line. In further modification the unloader device comprise a snap-action electric switch controlling the motor driving the pump and responsive to pressure in the service line. The unloader may also comprise a clutch between the pump and its driving motor operated by means responsive to service line pressure. Again the unloader device may comprise means to over-ridingly hold the pump inlet valve open in response to service line pressure.

Abstract: 1,255,149. Two-part couplings. EMPIRE PRODUCTS Inc. 26 Nov., 1968 [29 Jan., 1968], No. 56083/68. Heading H2E. An electrically insulating sleeve 22 has a collar 23 moulded therein, said collar having engaging means to co-operate with a contact 10 such that relative axial movement and rotation between the contact and sleeve are prevented. In Fig. 1, the collar has a resilient detent portion 26 which is deflected radially outwardly by a sloping face 17 of a stud 15 on the contact body as the sleeve is slid on to the body from the cable 12 until the stud engages a recess 24 whereupon the detent portion springs back behind the stud. A further embodiment employs the collar mouldedinto the sleeve in the reverse direction so that the sleeve is drawn over the contact before reaching the cable. Alternatively, a peg (92, Fig. 15, not shown) may be attaehedto the detent portion' and arranged to engage a niche (84) in the contact body, the recess and stud being omitted.  A further embodiment, Fig. 20, employs a forwardly extending lance 119 of the collar arranged to engage a shoulder 107 of the contact whilst a stud 105 engages a recess 116 of the collar. A keyway may be provided in the sleeve to guide the stud to the recess or a projection 30 may be provided on the exterior of the sleeve and directly above the recess to provide visual alignment of the stud and recess before engaging them. The collar may be of tempered aluminium and the sleeve of neoprene or other resilient or rigid plastics material. A further embodiment employs a malleable collar similar to that shown in Fig. 1, but the detent is manually deformed to block the exit of the stud from the recess. Reference has been directed by the Comptroller to Specification 1,000,584.

Title: Supply of thermal energy to a load
IPC: B29C48/92
Filed: 1969-12-01
Abstract: 1338999 Automatic temperature control systems COLTRON INDUSTRIES Inc 1 Dec 1969 [29 Nov 1968] 58533/69 Heading G3R In an automatic temperature control system, a temperature measuring signal is converted into a digital periodic pulse train and compared with a reference frequency to switch a triac or other device to control power to a heating means. In a simple arrangement an AND circuit receives sets of pulses and if two pulses from the train do not occur within the negative part cycle of the reference frequency output from the AND gate triggers a monostable multivibrator causing the triac to conduct for a fixed determined time. The periodic time of the pulses is low compared with the determined time which is itself short. A resistance sensor 11 is connected to a transistor Q2 which controls a constant current regulating transistor Q1 which charges a capacitor C18 at a regulated rate firing a unijunction transistor Q3 at a rate determined by the temperature sensed by resistor 11. Where this arrangement is mounted on a rotating body power is received by air cored coils L3 and the signal is transmitted through coils L1, L2. Coil L2 output may trigger a monostable multivibrator to produce a constant amplitude constant width pulse for each conduction of Q3 the resultant signal being applied over lines E, F to the circuit shown in Fig. 4. Coil L2 output may also be applied to an indicator and/or recorder calibrated in degrees of temperature. In Fig. 3 (not shown) an arrangement of similar configuration to Fig. 2 provides a reference frequency which is applied to a 4:1 frequency divider (35, 36) the output of which is applied over line 37 to a flip-flop chip A, Fig. 4, also to diode 43 which together with diode 44 forms a, AND gate. Flip-flop A is connected with a flip-flop chip B which is fed from lines E, F through an inverter 47 which furnishes a negative pulse train. If flip-flop B counts two pulses within the negative part of the wave on line 37, no output is given by the AND gate, but if a count of two occurs after line 37 swings positive, a positive output will be given from the gate. The AND output is inverted at 54 and operates a flip-flop circuit controlling a monostable pair of transistors 51, 52. For each positive output from the AND gate a positive pulse at terminal 9 of flip-flop 53 releases an oscillator including transistor 60 for a 0.1 second burst of 20hz pulses which are applied over lines M, N to the gate of a triac (not shown) passing current to a heater (also not shown). The reference frequency may be controlled and programmed by a computer and a number of systems may be connected to the computer in a time division mode of operation.
