Abstract: 1,200,519. Statistical apparatus. THOR DAHL Inc. 16 Sept., 1968 [15 Sept., 1967], No. 43872/68. Heading G4M. Cards marked on a predetermined area are separated from unmarked cards by detecting light reflected from the area and directing the cards along one or other of two paths in dependence on the whether or not the intensity of the reflected light exceeds a given level. Cards C are fed from a stack by a vacuum feeder to a pair of belts and thence to a scanning station S comprising one or more light sources 20 and a corresponding number of photo-cells 21. Each photo-cell is housed in a sleeve having a narrow bore at the bottom end terminating close to the card path. The light sources 20 and photo-cells 21 are simultaneously adjustable across the card path to select different areas of the cards for sensing. A pair of switches immediately following the scanning station S detect the presence of a card in the scanning station and respectively switch a bi-stable circuit and apply voltage across an S.C.R. The bi-stable circuit enhances the signal obtained from the photo-cells and applied to the S.C.R. gate so that a marked card causes a solenoid actuated flap to be raised and direct the card into pocket 41. The circuits are reset by a further card switch. Unmarked cards are deposited in pocket 40. A marking station M may be included comprising a rotatable, inked marking member 62 and a pivoted pressure roller 63 which is coupled to a control roller (not shown) deflected by each card passing through the station. The numbers of marked and unmarked cards may be registered by counters energized by switches associated with the sorting flap and in the card path following the flap respectively.

Title: Improvements in or relating to Nuclear Reactors.
Inventor: CAVE LESLIE
IPC: G21C1/00
Filed: 1966-10-04
Abstract: 1,193,649. Reactors. ATOMIC POWER CONSTRUCTIONS Ltd. 2 Oct., 1967 [4 Oct., 1966], No. 44337/66. Heading G6C. In a carbon-dioxide gas-cooled nuclear reactor, fault conditions producing a fuel element temperature rise, cause the fracture of a diaphragm and the release of a neutron absorber into the reaction zone. A vertical tie-bar in the fuel assembly is hollow and is divided into upper and lower chambers by the diaphragm. The upper chamber contains the absorber cadmium, the pressure of which rises with increasing temperature until the diaphragm bursts, thereby releasing cadmium vapour into the lower chamber, which is within the core reaction zone. In an alternative form helium gas is included in the upper chamber with the absorber material and the diaphragm is fractured by the gas pressure as the core temperature rises. The arrangement effects a fall in the reactivity in the fuel associated with the operative tie bar, the remainder of the core being unaffected.

Title: Improved helicoidal fan
IPC: F04D29/38
Filed: 1961-12-15
Abstract: 981,188. Axial-flow fans. SOC. LYONNAISE DE VENTILATION INDUSTRIELLE SOLYVENT. Dec. 15, 1961 [Dec. 19, 1960], No. 45093/61. Heading F1C. In an axial-flow fan comprising at least two blades mounted on a hub and the tips of which move in the immediate vicinity of a stationary outer casing, the maximum thickness of the transverse section of each blade taken on a cylinder coaxial with the impeller increases from the root of the blade to the tip. Figs. 4, 5 and 6 show cross-sections of a rotor blade of the fan shown in Fig. 3, taken on cylinders IV-IV, V-V and VI-VI respectively. As shown, the maximum thickness of the blade increases from a value LVI near the root to a value LIV near the tip. The maximum thickness is measured in a direction at right angles to the axis of rotation and is located at a distance from the leading edge of the blade equal to between “ and ¢ the chord length. The chord length may increase from root to tip. Instead of being cylindrical, the outer casing 10 or the impeller hub 11, or both, may be conical to accelerate the flow from inlet to outlet. Preferably, the ratio of the sum of the maximum thicknesses of all the blades to the circumference of the cylinder on which the blade cross-section under consideration is taken is greater than or equal to 0À08, at least for one cross-section. In the case of a fan having a cylindrical outer casing, the ratio preferably increases from root to tip, and reaches a value equal to or greater than 0À08 at the tip. The effect of all these measures is to reduce breakaway of flow from the impeller blades and to make the pressure more uniform from the hub to the outer periphery, thereby improving performance and reducing noise.

Abstract: 1,242,543. Cardiac defibrillators. SOUTH AFRICAN INVENTIONS DEVELOPMENT CORP. 26 Sept., 1968 [23 Nov., 1967], No. 45692/68. Heading A5R. A cardiac defibrillator is adapted to provide two successive electrical pulses to the heart with a time interval between the pulses which exceeds the depolarized period of the heart muscle fibres of the patient but which is less than the cyclic period of the heart of the patient, the pulses being of opposite polarity. As shown, the apparatus includes capacitors 40, 42 arranged to be charged by a circuit 44 and able to be discharged so as to produce at electrodes 52 two smooth, unidirectional pulses of opposite polarity and of about 12 milliseconds duration, the energy of each pulse being about 400 wattseconds and the time between the pulses being 200-500 milliseconds. The pulses are applied to the body by depressing a switch 54 to activate a relay R¢ which causes the capictor 40 to discharge and then, after a delay governed by an adjustable timer 56, a relay R<SP>2</SP>/ 2  operates to cause the second capacitor 42 to discharge. An alternative apparatus (Figures 6, not shown) is portable and suitable for open chest use by a surgeon, the apparatus comprising a transistor oscillator (T 1 , T 2 ) which is arranged to charge capacitors (C2, C3) via a transformer (X2). When a switch (S2) is depressed the first capacitor (C2) discharges to the heart and then, after a delay determined by a monostable device (T5, T6, T7), a second switch activates to cause the second capacitor (C3) to deliver the second pulse. The power of the alternative apparatus (Figure 6) is of the order of 40 wattseconds per pulse, and a charging circuit (Figure 7, not shown) for the battery (64) of the oscillator is described. The alternative apparatus may be in the form (Figure 5, not shown) of a handle portion (60) containing switches and meters, two flexible limbs (72, 74) projecting from the handle portion and being provided with electrodes (76, 78).

[Also in Division F2] Apparatus for limiting skidding of a moving vehicle such as a motor vehicle or aircraft (see Division B7) comprises a track brake means attached to the vehicle including a friction block 3 mounted at the rear of the vehicle and adapted to be suspended from two levers 12, 12a disposed in a vertical plane, the top ends of the levers being associated with the vehicle frame and spaced away from each other against elastic strap means 22, means being provided to maintain the friction block in an elevated position against the elastic means and control means are provided to retract the block under the body of the vehicle. The friction block 3, Figs. 5 and 6 (not shown), is composed of hardened steel nails 4 having flat heads buried in rubber blocks 3a, 3b surrounded by a metal frame 5. The nails 5 can be coated with graphite to permit them to slide in the rubber blocks 3b to accommodate for uneven road surfaces. The friction block 3 is normally retracted under the frame of the vehicle and in this position an electromagnet 43 is not energized and does not attract an armature plate rigid with a detent member which is adapted to enter a slot in a cam 29 to prevent rotation thereof. A knob 24 provided on the block 3 is engaged between a planar face 29a of the cam and the face of a resilient block 33. When the driver notices that his vehicle is beginning to skid, he presses the button that closes the circuit to the electromagnet 43 and the armature plate and detent member are consequently moved to the right against the pull of a spring, thus unlocking the cam 29 and allowing the block 3 to be lowered on to the road. When the path of the vehicle has been straightened out, the driver pulls on a cable member 48 to raise the block into its elevated position and thereby allow the detent means to lock the cam and thereby locate the friction block in its elevated position. In an alternative embodiment (not shown) the electrical circuit of the solenoid 43 is provided with an automatic switch, the solenoid being deenergized when the path of the centre of gravity of the vehicle deflects from the longitudinal axis thereof.
