Abstract: A self-propellable surf board 18 (Figs. 1 and 2 not shown) having a rigid hull body 20 in an overall traditional surf board configuration has mounted therein an engine assembly 46 mechanically coupled to a shaft 64 (also in Fig. 9, not shown) of a water jet propulsion unit 48 the propeller blades 248 of which draw in water through a grill 236 in the hull bottom 130 and deliver it through a stator assembly 244 into a propulsion tube 126 terminating in output nozzle 128.  The bow and stern portions 24, 26 are filled with foamed-in-place plastic, the mid-portion 28 is divided by transverse bulkheads into forward, engine and aft compartments 38, 40, 42.  A subcompartment 56 houses the engine recoil starter reel, and a sub-compartment 106 has a vent 110 for supplying air to the engine (see Division F1).  Engine cooling water is drawn from a port 68 below the keel and delivered by a pump 66 into a line 72 emptying into the engine exhaust pipe system 74 just aft of a check valve 76.  In Fig. 5 (not shown) this check valve is placed between the forward portion 170 and the aft portion 182 of the exhaust pipe and comprises a hinged member 174 formed with a buoyant cap 185.  Exhaust pressure forces the valve open, otherwise the member 174 closes under gravity, or due to its buoyancy when the valve housing becomes filled with water owing to the board capsizing or for any other reason.  The under surface 130 of the hull is provided with blister surfaces 132, 134, 136, 138 forming part of self-bailing assemblies 146 (Fig. 3, not shown) in which a moulded plastic body 148 with cylindrical openings 160 mounted in a plate 140 has a flexible disc closure member 154 so that water above the assembly will fall on to the interior surface 130 and be drawn into the slip stream of the hull through an opening 144.

Abstract: 1,133,550. Regulating I. C. engines. ROBERT BOSCH G.m.b.H. Nov. 2, 1967 [Nov. 3, 1966], No. 49778/67. Heading F1B. [Also in Division G1] The duration of the period in each cycle during which the valves of the fuel injection system of an I. C. engine are open is determined by a transistor circuit in accordance with the degree of vacuum in the inlet manifold, and is provided with a fuel inhibition facility when the acceleration pedal is not depressed, the engine temperature is above a preset minimum and the engine speed is above a preset minimum idling value. Normally the solenoids 13 of the fuel injection valves are energized by the amplified pulses from monostable multi-vibrator 18, which receives input pulses from engine driven contact breaker 20, giving two pulses per revolution, and delivers synchronous pulses whose duration is controlled by the pressure in the inlet manifold 12. These pulses are fed through synchronous change-over switch 24, alternately to transistor 27, energizing the left hand solenoids 13, and to transistor 28, energizing the right hand solenoids 13. The base of transistors 27, 28 is connected to a bi-stable multi-vibrator 38 which inhibits energization of solenoids 13 when accelerator pedal 87 is not depressed and associated switch 86 is closed and when the engine temperature, as used by a bimetallic switch 85, is above a minimum and switch 85 is closed. When either switch is open, diode 70 conducts, transistor 46 conducts, its collector is earthed and fuel injection proceeds normally as above. When both switches are closed diode 70 is blocked, and the operation of multi-vibrator 38 is dependent on the frequency of the pulses from contact breaker 20 fed in via capacitor 59 and resistor 62. If the frequency is lower than that of normal idling speed, components 52-59 pass the pulses to block transistor 45, transistor 46 conducts and fuel injection proceeds normally. If the frequency is above that of idling speed components 62-69 pass the pulses to block transistor 46 and fuel injection is inhibited.

Abstract: 1,107,439. Selective signalling. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 26 Nov., 1965 [27 Nov., 1964], No. 50290/65. Heading G4H. [Also in Division H2] In a stepper motor and control circuit the position of the motor rotor 20 is detected by a means which provides a signal when the rotor has reached a predetermined position and an enabling means prevents the supply of pulses from a pulse generator 44 to a controller 10, which energizes the stator windings, until it receives a signal from the detecting means indicating that the rotor has reached the next predetermined position so that the controller then steps the rotor to the next position. As shown, the rotor may step clockwise or counterclockwise depending on which of the signals 11, 12 are supplied to the controller 10. A disc 22 which rotates with the rotor 20 allows illumination of a photo-cell P1, P2, P3, P4, corresponding to the position of the rotor A, B, C, D. The signal supplied by the active photo-cell and one supplied via lines 14-17 from the controller pass to an AND gate 29-32. The output from one of these gates supplies a signal, via OR gate 41, to an enabling gate 43 which then allows a signal from pulse generator 44 to pass to one of a further two AND gates 48, 49, which supply a signal to step the rotor to a new position., The rotor may be a permanent magnet. Signals may be supplied to each of the stator coils in turn to give 90 degree steps or, e.g. windings A and B may be energized together to give a 45 degrees step. Analogue to digital converter.-A voltage comparator 52 compares positive or negative analogue input signals 53 with a reference voltage on slider 54 and gives a difference output on either line 50 or 51 to effect clockwise or counterclockwise rotation of the rotor. The rotor continues to step until the reference voltage has equalled the input analogue signal by movement of the slider 54 connected for rotation with the rotor. A counter 60 provides a digital output representing the input analogue signal.
