Title: Centrifugal pumps
IPC: F04D9/02
Filed: 1970-02-03
Abstract: 1293966 Priming centrifugal pumps SOC DU CARBURATEUR ZENITH 3 Feb 1970 [3 Feb 1969] 5087/70 Heading F1C A centrifugal pump is arranged to enclose, when stopped, a predetermined volume of liquid so as to ensure its automatic priming, and comprises means for sealing its delivery conduit when the upstream end of the inlet piping is no longer immersed in the liquid, the delivery conduit including an obturator biased towards closure of the delivery conduit by a return force and operatively connected with the movable wall of a space of variable volume communicating via a channel with the inlet conduit of the pump so as to open when this space diminishes in volume. A piston 17 is urged by a spring 19 (or by gravity) into the position shown, in which it closes the discharge conduit 4. The left-hand side of the piston is subjected, via a hole 24 and a duct 23, (not shown) to the pressure in the inlet space of the pump, while the right-hand side is subjected, because of imperfect sealing at the end 17b, to the pressure in the discharge space 14. During normal working, the difference in pressure between the two sides of the piston 17 overcomes the force of the spring 19 to move the piston into the position in which the discharge conduit 4 is open. If the inlet pipe becomes uncovered by liquid, the consequent rise in the pressure at the inlet causes the piston 17 to return to the position in which it closes the discharge conduit 4 and prevents discharge of the priming quantity of liquid remaining in the pump. The means for obturating the discharge conduit 4 may be separate from the piston and connected to it by linkage, and the piston and spring may in this case be replaced by a bellows or capsule.

Class 139 An alarm time-piece which can be worn or carried has a sonorous diaphragm which is sprung directly into the base of the casing, and oscillatory striker means to cause the diaphragm to produce sound, said base being sprung on to the casing caseband. The hammer 6, Fig. 1, strikes a member 10 carried by a diaphragm 9 held in a groove 8a of the back 8 which is a snap fit on the caseband 1. The diaphragm is held in position by its own elasticity and when fitted in position assumes a curvature similar to that of the back 8. Tthe back 8 has holes 8b through which the alarm sound may pass. In another embodiment, Fig: 2, the member 16 struck by the hammer 10, 11 is carried by a member 14 riveted to a raised part 12b of the diaphragm 12 which at its circumference engages a groove 13a in the back of the case. The edge 13b of the groove 13a is beaded over the edge of the diaphragm. The hammer head 11 is of hardened steel. A ring having a circular series of holes may be positioned inside the back and may be moved to cover wholly or in part the holes in the back so as to vary the tone of the alarm signal. In other embodiments the movement of the diaphragm may be damped by manual movement of a member to abut the diaphragm. In one such embodiment the damping member is longitudinally moved whereby its end moves up a ramp to abut the diaphragm. In the other such embodiment the damping member is formed by a pivoted double armed lever which is rocked to cause one of its ends to move up a ramp to abut the diaphragm.

Title: Acceleration detecting circuit for an electronic control unit in an antiskid brake system
IPC: B60T8/172
Filed: 1975-02-10
Abstract: 1487983 Determining acceleration electrically DBA SA 10 Feb 1975 [18 Feb 1974] 5608/75 Heading G1N [Also in Division.F2] A circuit for providing signals to an electronic control unit for an anti-skid motor vehicle braking system includes a differential amplifier 10 receiving at its non-inverting input 12 a voltage VE from a wheel speed sensor CV via a frequency-voltage converter CFT and receiving at its inverting input 14 a voltage which increases linearly with time. Diodes 20, 22 of opposed polarities are connected in parallel across the inputs of the amplifier. The dashed line DV in Fig. 2 represents vehicle speed and as the sensed wheel is braked voltage VE falls, voltage VC being clamped to VE by conduction of the diode 20. At time TG 1  the wheel is accelerated and the voltage difference between VC and VE falls below the diode 20 threshold so it blocks. Thus the capacitor 18 voltage VC rises in accordance with a linear law imposed by the constant-current circuit 16, as shown by portion bc. At time Tf VE exceeds VC and the differential amplifier output VS rises to a logic level 1 which persists until VC again exceeds VE. The output VS is applied to a two-or three-phase brake pressure control system incorporating solenoid valves, to control the instant at which the brakes are re-applied.

Patent GB-1594503-A (GB)
Title: Plastics injection moulding machine including a defective moulding detecting device
IPC: B29C45/76
Filed: 1978-02-15
Abstract: For detecting moulding faults, the time is measured which the ram of the injection moulding machine takes between two measurement points (l1, l2) of the injection moulding stroke (l0). In order that certain tolerances regarding the temperature of the injection moulding material and external influences such as actuation pressure in the hydraulic system can be taken into account, time ranges (D, E and F, G) are preset at both points. A path-time curve (A) can thus vary within a limited range without a moulding fault signal being generated. Moulding fault signals are thus only generated when the path-time curve (B, C, H) runs, at least at one measurement point (l1, l2), outside the set time range (D, E and F, G). <IMAGE>
