Abstract: 1,108,468. Counters. ENGLISH ELECTRIC CO. Ltd. 18 Oct., 1966 [19 Oct., 1965], No. 44329/65. Heading G4D. [Also in Division F2] A mechanism for assisting the drive from a disc 18 through a gear train 20, 17, 22, 21 to a digital register of an electric meter comprises bevel planets 14 meshing side wheels 16, 13 respectively connected to the gear 17 and by a spring 12 to a shaft 11 carrying the planets 14 and driven by an electric motor at a constant speed that is higher than the speed of the gear 17 so that the gear 13 rotates faster than the shaft 11 to energize the spring 12 which reacts through the gear train to apply a torque to the gear 17 that assists the drive. To prevent the assisting torque from influencing the speed of the driving disc 18 a unidirectional drive such as a worm and wheel 19 or escapement mechanism is provided. Some of the teeth of the gear 13 are missing to limit the energization of the spring.

Title: Gas-driven pulsating water jet drive for watercraft
IPC: B63H11/12
Filed: 1974-10-14
Abstract: 1478862 Jet propulsion apparatus JASTRAM WERKE GmbH KG 14 Oct 1974 [15 Oct 1973 19 Sept 1974] 44432/74 Heading B7V A gas pulsating drive unit for a wateroraft comprises a water duct 2 with an inlet 5 and slidable hollow tubular closure member 4 disposed on a body 3 within the duct. The body 3 contains a gas chamber 6 which is fed from, e.g. a gas generator, via a duct 7 passageway 24 and ports 12 and 25. When the pressure in chamber 6 is sufficient to cause a control member 17 to move against a compression spring 19, duct 16 is opened and the pressure acts on a piston surface 13 of the member 4 and moves it to close inlet 5. In this position ports 8 and 12 are aligned, and the gas in chamber 6 is released to force the water in duct 2 out through the unit outlet. When the pressure in chamber 6 falls, spring 19 returns the control member 17 to its original position and the cycle is repeated. In Fig. 1 the closure and control members are disposed on the axis of the unit. In Fig. 2, not shown, the closure member has a sealing lip (21), (22) and a stepped piston surface (13a), (13b) forming a buffer chamber (15b). In Fig. 3, not shown, the body (43) supporting the closure member (44) is disposed in front of inlet 5, and moves backwards to close the inlet.

Abstract: 1395720 Counting apparatus W & T AVERY Ltd 25 Sept 1972 [25 Sept 1971] 44802/71 Headings G4D and G4A Counting apparatus is arranged to form the value f 1 f 4 /f 2 f 3  from four input frequencies f 1 -f 4 . A counter 10 is first arranged to count up pulses at frequency f 1  for a set number of periods of the frequency f 2 . The counter 10 is then arranged to count back to zero with pulses at frequency f 3  and during the time that it is so counting a further counter 14 receives pulses at a frequency f 4 . By arranging that two of the frequencies are fixed and the other two are equal and dependent upon the output of a transducer, the output of a transducer operating to a square law can be rendered linear. In a modification (Fig. 2, not shown) a first frequency f a  is counted for a period of f 2  and then a second frequency f b  is counted for the same period (so that f 1  = f a  + f b ); the gate G4 receives the difference between the first and second frequencies (so that f 4  = f a  -f b ); and f 2 , f 3  are constant. By this arrangement the count accumulated in the counter 14 will be proportional to f a <SP>2</SP> + f b <SP>2</SP>- In a further arrangement (Fig. 3, not shown) using two counters 10 the function (f a <SP>2</SP> + f b <SP>2</SP>)<SP>-1</SP> is formed.

Rotation of the heat exchanger via a motor 2 causes air to be drawn in along the path indicated by the arrow 19, the air flowing radially outwardly across the fin and tube arrangement and into volute ducts 21 whence it is discharged via outlets 22. At one end of the heat exchanger is a dish-shaped structure 3 the interior of which is divided by a partition 4 into two spaces 4a, 4b respectively communicating with the flow and return passages.

Abstract: 1464565 Light source measuring apparatus XEROX CORP 28 Oct 1974 [29 Oct 1973] 46497/74 Heading G1A Apparatus for testing an elongated apertured tubular light source 24 comprises photo-cell 18 for measuring the source output in a given direction, a filter on frame 44 interposable between source 24 and photo-cell 18 and means 26, 28 for mounting source 24 horizontally with its longitudinal axis perpendicular to said direction and allowing its aperture to be rotatably aligned with collimator 40 between filter 42 in position and photo-cell 18. The analogue signal is converted to digital. On bar 30, which is secured moveably to frame 32 and has indicator marks, are slideably mounted brackets 26 and 28 having rotatable lamp sockets. Four filters 42 are held by retaining rings on disc 44, bearing five magnets, four indicating filter positions and one a fifth position. A cover is mounted over wheel 20 and belt 46. Motor 22 makes 200 steps per revolution. Depressing button 48 allows disc 44 to rotate to the fifth position, detected by magnetic relay 50, and sets flip-flop 52, which through AND gates 11 and 13 gates step pulses from 180Hz oscillator 66 to translator module 54 and which is disabled by signal SW2, which also via delay logic 31 and invertor 33 advances the printer paper. Signal SW1 clears mode counter 56 and character counter 58. On switching the RUN switch, the AUTO signal triggers a single shot timer 60 through NAND gate 15 and uni-junction timer 62. Signal SSD from NAND gate 17 sets run flip-flop 64 to activate the FILAMENT ON signal and the lamp, and a-constant current linear reactor is powered as the signal from timer 60 finishes and RUN is actuated gating step pulses to module 54, so that disc 44 rotates until the correct filter position, which has been determined by switching mode counter 56, is detected by magnetic relay 68, which triggers single shot timer 72 disabling the step pulses for 500ms while a reading is taken followed by a PRINT COMMAND signal an INHIBIT signal and a HOLD signal to maintain digital display. Relay 68 also toggles character counter 58 giving binary coded signals for red, green, blue and cyan gated through register 35 to switch on a POT channel on the printer. Thus at the end of 500ms, the printer prints the reading and the filter character. The above procedure is repeated for each filter position. The process ends when relay 50 of the fifth position causes shut down.

The applying lever 29 is actuated either by admission of fluid to a cylinder 37 with which the lever is engaged and whose piston 38 reacts on the shaft 15  through a rod 39, or manually through a rod attached to the cylinder via a lost-motion connection. Upon actuation of the applying lever pressure is applied to a second pad 24 carried by a backing plate 25 via a rod 32 having rounded ends engaging recesses in the plate 25 and applying lever, whereby plate 25 may move circumferentially under the drag force between the pad and the disc 12. This causes movement of balls 26 in opposed inclined recesses in the plate 25 and servo lever 17 to create additional pressure on the pad, the reaction force created by both initial and additional pressures acting on the pad 21 via the interconnecting rod 41. Return springs 49, 53 ensure brake release when the applying force is removed. The rod 41 is in the form of a bolt having a part-spherical head 42 and threaded engagement with a partspherical nut 45, the latter being automatically rotated to take up brake pad wear through a mechanism 48 as disclosed in Specification 1,037,482.
