[Also in Division E2] A one-piece ring box, injection moulded from polypropylene, has an integral hinge with a spring biasing action to open the box on release of a securing catch. In Figs. 5 and 7, which are sectional and plan views respectively, the box comprises a base 31 having a bottom 33, end walls 34, and sloping walls 35 and 36 at the front and rear, with a lid 32 having ends 37, and curved front and rear walls 38 and 39, the base and lid being connected by the hinge assembly shown generally at 40; there is also a front catch 50. The rear walls 36 and 39, of the base and lid are joined in end to end relationship, at either side of a central spring arm 16<SP>11</SP> and connecting arm 19<SP>11</SP>, by flexible bending lines 2011 and 2111 formed adjacent to V-shaped depressions in the outer wall surfaces. The spring arm 16<SP>11</SP>, integral with lid rear wall 39, is formed during moulding inclined outwardly from 39, and its other end connects along a flexible bending line 17<SP>11</SP> to a connecting arm 19<SP>11</SP>, itself flexibly integrally connected at 18<SP>11</SP> to the base rear wall 36. Above and below bending lines 2011 and 21<SP>11</SP>, the lid and base rear walls are bent in at 40 and 42 to enclose the part of the box between the hinge and end walls, when the box is closed; the edges of the turned in portions abut on closure to form stops for the hinge. On closing the box, the spring arm 16<SP>11</SP> is stressed by connecting arm 19<SP>11</SP>, into alignment with rear wall 39, and remains so deformed until the catch 50 is released, when, due to the elastic properties of the polypropylene, it returns to its original angular relationship with 39 and the lid opens to the position shown in Fig. 5. The box has two serrated clamping parts 43 to hold a ring 44; the box inner surfaces may be coated with flocking and the outside suitably embossed. The box may alternatively be moulded from other synthetic thermoplastics, such as nylon, or the hinge may be separated from but secured to the box.

Permanent bleed orifices 34 in the periphery of the shroud 30 discharge into a housing 15. The blade 70 is pivoted at 73 to the housing 15 and is fast with an arm 72. A control plunger 82 subject to the pressure of the centrifugal pump discharge acts on the arm 72 in opposition to a spring 87 adjustably pre-stressed by a knob 85 which sets the desired centrifugal pump delivery pressure. Variation in the discharge pressure of the centrifugal pump varies the position of the arm 72 and blade 70 to vary the filling of the coupling. An input driven pump 51 delivers liquid to the jet 65. The liquid in the housing 15 is cooled by a heat exchanger 94. Blades 42 on the shroud 30 accelerate liquid supplied thereto from the jet 65.

Abstract: 1443324 Control systems for consumption apparatus CUTLER-HAMMER EUROPA Ltd 10 Oct 1973 [10 Oct 1972] 47378/73 Heading H2H [Also in Division H3] Closure of a switch SW causes delayed operation of a relay CR whose contacts CR1 turn on a power switch Q3 to supply a load L from the D.C. or A.C. voltage on the switch SW. Q1 senses when the impedance of SW is low enough to be properly "on" by turning on and causing Q4 to charge C 4  to a voltage (+15v), which gives a Zener-stabilised 10v to the timing circuit P1, R17, C5. Diodes D3 D4 give halfwave rectification if A.C. is used. C5 charges at a rate set by P1 until PUT Q7 turns on to fire S.C.R. Q8, thus operating the relay CR. When SW is opened Q3 turns off a lid Q1 senses a high enough impedance thereof to turn off Q4 and disable the timing circuit; also Q2 goes off and permits R2 to turn on reset transistors Q5, Q6 which respectively discharge C4 and C5. A voltage variable resistor ZNR protects circuit components from transients. When the SCR Q8 is on, a LED is on to indicate operation of the relay. While C5 is timing, LED is flashed on and off by a stable pair Q9, Q10.

Abstract: 1,181,338. Automatic acceleration control. WESTINGHOUSE ELECTRIC CORP. Oct.7, 1968 [Nov.29, 1967], No.47392/68. Heading G3R. The invention relates to a system for bringing to a halt a vehicle such as a train or lift cage. A pulse counter 12, a tachometer 14 and an accelerometer 22 respectively measure the position, speed and deceleration of the vehicle and provide respective control signals; a computer 10 receives the position and speed signals and generates from them a signal representing the deceleration necessary to halt the vehicle at the required position. This signal is modified by a non-linear circuit 20 and then compared at 18 with the actual deceleration signal to control the drive of the vehicle. The non-linear circuit has the effect of increasing the higher values of deceleration thus tending to halt the vehicle sooner than required; this allows for errors in the measuring devices 14, 22. When the vehicle gets close to the required position a switch 21 is closed by the computer 10 to disconnect the circuit 20. The controller 24 includes means limiting the maximum acceleration to a value commensurate with passenger comfort. The accelerometer 22 may be of pendulum or spring types Fig.6, 7 (not shown) and the circuit 20 may consist of an amplifier with negative feedback applied through a Zener diode (34, Fig.5 not shown).

Crystal transducers 52, connected to electrical pulse transmitting/receiving units 60, are acoustically coupled to the tube 10 by plastics wedges 54, a grease film, wear shoes 56, and a water-glycerine coupling fluid, and introduce shear waves travelling around the wall of tube 10. Flaw-echo signals from small portions of the wall (which portions effectively scan the wall in four adjacent helical paths) are selected by time-gating the returned flaw-echo signals from the four transducers 52 and are applied to a recorder 64 and an alarm system. In order to detect flaws irrespective of their orientation, search units 44 and 48 introduce shear waves travelling in one direction around the wall of tube 10, while search units 46 and 50 introduce shear waves travelling in the opposite direction. Details of a method of calibrating the apparatus sensitivity using a reference tube with standard notches in the outer and inner walls is given, and the mounting of transducers 52 in the search units is described in detail (Fig. 4, not shown).
