Abstract: 1461120 Blow-moulding J MEHNERT 21 Aug 1974 [21 Aug 1973] 36793/74 Addition to 1394310 Heading B5A Blow-moulding apparatus comprises two blow mandrels, a preforming device on which a preform is formed and two blow moulds for the two respective mandrels, means to supply compressed air to each mandrel to blow-mould the preform in the blow-mould, and an auxiliary compressed-air-supplying member to co-operate with each blow-mould and supply pressure to the expanded preform in the blow-mould after removal of the blow mandrel. As shown in Fig. 1, the support 1 carries two sets of two blow mandrels 2, 2<SP>1</SP>, 3, 31 which are engageable with preforming mould cavities 4, 4<SP>1</SP> and blow-mould cavities 5a, 5b or 6a, 6b. The blow-moulds 5, 6 are also engageable with compressed air supplying members (7, not shown) and 7<SP>1</SP>. In the position of Fig. 1, preforms are formed in cavities 4, 41 and previously formed preforms are blow-moulded in cavities 5a, 5b while air is supplied to blow-moulded articles in cavities 6a, 6b by member 7<SP>1</SP>. Support 1 is raised and member (7) supplies air to the articles just blow-moulded in cavities 5a, 5b (Fig. 2, not shown). Member 7<SP>1</SP> is removed, the articles are ejected from cavities 6a, 6b and the support 1 is laterally displaced (Fig. 3, not shown). Support 1 is then lowered for a fresh cycle of preforming on mandrels 2, 2<SP>1</SP> in cavities 4, 4<SP>1</SP> and blow-moulding by mandrels 3, 3<SP>1</SP> in cavities 6a, 6b. Preforming may be effected by injectionmoulding, dip-moulding &c. In the embodiment of Figs. 6a, 6b, 7a, 7b (not shown), the article neck is injection-moulded in mould parts (25) around blow mandrel (22a) which then move away from the extruder (4<SP>1</SP>) as tube (20) is extruded. Shears (21) cut the parison which then moves laterally on members (22a, 25) to blow-mould (24) where it is blow-moulded by mandrel (22a), further air being supplied by member (26) to the article in mould (24) as members (22a, 25) return to the preforming station. In Fig. 8 (not shown) the preform is only partially expanded by the blow mandrel (29) and may be stretched before completion of blow-moulding.

Title: Fluid speed measuring system
IPC: G01F1/66
Filed: 1964-09-09
Abstract: 1,073,194. Ultrasonic fluid-flow meters. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Sept. 9, 1964 [Sept. 13, 1963], No. 36992/64. Heading H4D. In a system for measuring the flow velocity of a fluid in a pipe, an acoustic signal is propagated diagonally across the pipe in both directions between two transducers both as a continuous wave signal and as a pulse signal. In the embodiment of Figs. 1 and 2, two transducers (1 and 2) are connected through a reversing switch to a transmitting signal generator (5) and a receiving amplifier (7). During a first measurement phase transmitted and received signals from generator (5) and amplified (7) are heterodyned in mixers (11 and 8) respectively with signals from a local oscillator (9), and are then phase-compared on a phase-meter (15). With the reversing switch (30, 40) in its first position (I), acoustic signals travel from transducer (1) to transducer (2) and the phase-meter (15) indicates a propagation time T 1 ; with the switch (30, 40) in its second position (II), the phase-meter (15) indicates the propagation time T 2  from transducer (2) to transducer (1). A computer (16) derives the value T 2 -T 1 . During a second measurement phase, control pulses from a monostable circuit (18) open a gate (17) to feed the transmitting transducer periodically from the signal generator (5). The monostable circuit (18) is triggered by a feed-back signal from the receiving transducer, and hence acoustic pulses are generated at a repetition frequency 1/T 1  or 1/T 2  according to the position of a reversing switch (101, 102) connecting the transducers (1, 2) to the gate (17) and receiving amplifier (7). These repetition frequencies are measured on a meter (19), and the computer (16) derives the value 1/T 1  -  1/T 2  and then computes the product (T 2  - T 1 )(1/T 1  - 1/T 2 ) from which the fluid flow velocity may be calculated without a knowledge of the speed of sound in the fluid.

Title: Device for replacing a normally active apparatus in a transmission system or replacing a normally used route by a spare apparatus or a spare route in the event of a breakdown in the normally used apparatus or route
IPC: H03F1/54
Filed: 1955-12-30
Abstract: 785,961. Transmission systems. STANDARD TELEPHONES & CABLES, Ltd. Dec. 30, 1955 [Dec. 31, 1954], No. 37416/55. Class 40 (4). In a transmission system provided with standby equipment .8, 9, Fig. 2, or a spare route 2, the normal equipment 5, 6 is coupled to a consumer circuit 4 through a negative feed-back amplifier and a hybrid coil circuit, and fully operative spare equipment which is coupled to the amplifier output circuit, the feed-back path and a bias developing circuit feeds the load when the normal coupling conditions are changed by the blocking of the amplifier by the bias circuit upon failure of the normal equipment. Failure of the junction amplifier also results in the coupling of the spare equipment to the consumer circuit. In the junction arrangement, Fig. 4, the consumer circuit represented by R3 is fed normally by an input A to transformer T1, the input eb from the spare circuit B being suppressed by its manner of connection to the feed-back circuit. Circuit R1, C1 provides a standing bias for the valve V1 and a further circuit R6, C4 which is fed with the rectified output from transformer T takes down the working point of the valve when input A falls away. A transformer M which is saturated by the normal anode current is desaturated by the resulting fall of anode current and a large bias is provided by rectifier W1 from an auxiliary supply which may be the heater supply to ensure a definite cut-off. The circuit is prevented from operating when there is no input from the spare equipment by a rectifier W3 which is rendered conductive when the voltage across condenser C3 exceeds that across condenser C4. The Specification includes a mathematical analysis of the circuit.

Title: Improvements in apparatus for delivering weighed portions of material to packing machines
IPC: B65B1/32
Filed: 1946-12-20
Abstract: 620,433. Weighing apparatus. SHARMAN, C. F., and DAVIS, A. C. Dec. 20, 1946, No. 37496. [Class 143] [Also in Group XXX] An apparatus for delivering weighed portions of material to a packing machine comprises receptacles to which the portions are to be delivered for subsequent packing, and one or more weighing scales which the receptacles pass, each scale being provided with scale-emptying means whose operation is controllable to allow for the individually varying time intervals required for loading the scale to the correct weight, and said scale-emptying means being so arranged that when allowed to come into operation, its action synchronises with an empty receptacle being properly located to receive the portion from the weighing scale. When a counterweight 24, Fig. 3, is exactly balanced by material manually inserted into a weighpan 22, a hole in a member 41, carried by a frame 37 attached to the weigh beam 11, is in alignment with a hole 42 in a fixed plate 44 and a hole 46 in a fixed bar 45 so that a spigot 48 can pass therethrough when a rod 49 is moved upwardly by a pedal 13. Until the holes are aligned, the pedal 13 cannot actuate the lever 52 which, when moved, through a link 55, a bell crank lever 56 and an abutment surface 58, Figs. 3 and 5, pivots a trip member 59 about a fixed pivot 60 so that it engages with a lever 61 pivoted on the bottom of one of the containers 10, carried past the plurality of scales on endless chains 8, 9. The other end of lever 61 then strikes against a pivoted member 63 which through a bell crank lever 66, rod 68, wheel 69 and lever 34, pivoted at 35, lifts a yoke 33 which by engaging pins 31, 32 on bell crank levers 28, 29 opens the two halves 26, 27 of the scale pan 22 and material contained therein is scraped by fixed scrapers 75 into the receptacle 10 located thereunder. Each lever 61 after operating an unloading mechanism takes up a position which renders further unloading into the associated receptacle 10 impossible until said material has been discharged and the lever reset. In another embodiment, Fig. 9, the lever 61 is replaced by a rod 73 which may be slid across the bottom of the receptacle, against the action of a spring, by engagement of a modified trip member 59 with its cam head 74, the other end of said rod operating a member 63 as before, and to prevent multiple unloading into each receptacle the cam heads of the rods are arranged, sequentially, at different heights so that they are each engaged by one abutment member 58 only in each circuit past the weighing pans. In a further embodiment (not shewn) the mechanism serving to lock the beam 52 is replaced by a lamp, a fixed slit, a slit movable with the weighing scale and a photo electric cell operating, through an amplifier and solenoid, a latch which prevents movement of the beam 52.
