Title: Hydraulically driven rotary atomiser
Inventor: SPILLMAN JOHN JAMES
IPC: B05B3/04
Filed: 1989-05-20
Abstract: A rotatory drum (1) is mounted on a bearing assembly (2, 3, 4) which carries, for supply of pressurised liquid via a filter and valve (24), a nozzle (28, 29) which impinges the liquid on the drum interior and rotates it without a motor. Several slotted rings (9-12) ensure even distribution of the liquid when it reaches, near the open end of the drum, a plate (15) which carries 80 radial grooves on its proximal face, the grooves terminating in teeth (16) from which the liquid is emitted as streams of uniform droplets, e.g. of size 100 - 800  mu m. The rear face of each groove is preferably vertical, to assist retention of the liquid on the plate. A grooved plate (37) can also be provided at the closed end of the drum (Fig 6, not shown) with a further set of slotted rings (33-36), and the nozzle placed centrally between the ends of the drum. The apparatus allows atomisation to a uniform small droplet size without the use of electrical power for the atomisation, and it is useful for agricultural spraying. <IMAGE>

Patent GB-2224176-A (GB)
Title: Radar range finder
Inventor: PARDOE RICHARD JOHN LEFROY
IPC: G01S13/70
Filed: 1989-10-17
Abstract: A radar range finder suitable for use as a radar altimeter is described. The radar range of the received signal is determined by a tracking gale 9 whose output is stored in a tank circuit 26. The energy in the tank circuit is then allowed to decay away with time and the amplitude of the signal is sampled at some time after the initial injection of energy. This sampling time is fixed with respect to the original transmit pulse time of the radar thus causing near range echoes to decay more in the tank circuit than distant echoes which are more delayed before they enter the tank circuit. The output from the sampling gate which provides this range compensation is then filtered and amplified by the receiver system. <IMAGE>

Title: Processing television signals
Inventor: PARKER DAVID WILLIAM
IPC: H04N7/015
Filed: 1989-11-17
Abstract: A high definition television signal from a source such as a television camera (1) is applied to three parallel processing branches the operation of each branch being determined by a range of motion. An 80ms branch (3, 4, 5) and a 20ms branch (6, 7, 8) each respectively have a two dimensional low pass filter, a sub-sampler and a line shuffler. A 40ms branch (9, 10) only has a two dimensional filter and a sub-sampler. A motion estimator (14) determines the degree of movement of picture blocks and a decision unit (13) decides on the appropriate branch, the motion vectors for the 20ms and 40ms branch and the blocks to which these are applied. This information is applied to a DATV formatting device (15) which produces a menu of motion vectors and codewords for each block. A switch (11) selects the appropriate branch for each block. <IMAGE>

Title: Thin film calorimeter
Inventor: WRIGHT J D
IPC: G01N25/48
Filed: 1990-03-28
Abstract: An interferometric microcalorimeter for studying heats of adsorption, absorption and chemical reaction involving gases, which uses a single-mode optical fibre Mach-Zehnder Interferometer with a short length (11) of the active arm (12) coated with a film (23) of a sorbant substance. Optical pathlength changes in this arm produced by temperature, and hence refractive index, changes are compensated by stretching the reference arm (14) using a piezoelectric cylinder (18). The voltage applied to this cylinder (18) is proportional to the temperature change in the active arm (12). The system can be calibrated using heat pulses generated electrically in a silver coating on an active arm which has been substituted for the active arm (12). The interferometer is isolated in a large evacuated chamber (22) connected to a carefully-thermostatted high vacuum sample chamber (20) containing the active coated fibre (12) and an identical length of uncoated fibre (14) compensating for ambient temperature fluctuations. The small-diameter (100 mu m), low-heat-capacity (1.7 mu J/mK/10cm length) fibre (12), with 1 mK temperature changes measurable above the background noise, gives  mu J sensitivity. The calorimeter has been used to study the interaction of NO2 with Pb and Cu phthalocyanines. <IMAGE>

Patent GB-905283-A (GB)
Abstract: 905,283. Tens transfer mechanisms. MONROE CALCULATING MACHINE CO. Jan. 24, 1961 [Feb. 2, 1960], No. 2735/61. Class 106 (1). In a calculating machine register, each tens transfer actuator includes a coupling member, set when a register wheel moves from a first to a second registering position, to form a connection between the transfer actuator and a common transfer actuator drive means in order to provide a primary transfer operation, and each transfer actuator is adapted to operate conditioning means to condition the next higher order transfer actuator for a secondary transfer operation by the drive means when the register wheel is in its first registering position. Addition and subtraction.-During the forward stroke of a bail 3, Fig. 4, springs 2 move actuator racks 1 to differential positions according to the data entered. Cradles 9 supporting intermeshed add pinions 5 and subtract pinions 6 are now raised to engage one or other set of pinions with the actuator racks. During the return stroke the racks 1 enter the data by differential rotations of the pinions 5, 6. Primary transfers.-When a pinion 5 or 6 passes through the " 9 " position an extended tooth 5a or 6a engages and passes beyond nose 16a of a primary conditioning lever 16 rockably mounted on a shaft 17, thus rocking the lever 16 counter-clockwise so that it rocks a link 19 pivotally connected to the end 10a of a transfer gear segment 10 associated with the next higher order pinions. This causes a nose 19a of a link 19 to be positioned immediately above the upper edge of a common bail 14, which is then rocked clockwise so that nose 19a and the associated gear segment 10 are similarly rocked clockwise. Whilst in this position, cradle 9 is moved downwards to engage the associated pinions with the gear segments 10. When bail 14 is restored, its lower edge engages arms 10a of the displaced segments 10, restoring them and entering one unit in their associated pinions. Secondary transfers.-Associated with each order of the register is a lever 22. If the engaged pinion 5 or 6 stands at " 9 " when rack 1 has been restored, nose 22a of lever 22 engages with the extended tooth 5a or 6a, rocking lever 22 and a link 25, pivotally connected to the arm 10b of the next higher order transfer segment 10, to position its nose 25a immediately below a pin 27 extending leftwards from the arm 10b of the lower order gear. Thus, if the lower order segment gear 10 is rocked by bail 14 in a primary transfer operation, pin 27 of this segment will cause the higher order segment to rock simultaneously to condition it to effect a secondary transfer. Fugitive one.-, If the highest order pinion 5 or 6 stands at " 9 " the associated lever 22 will be rocked as described when the register pinions are raised. The associated transfer segment 10 and a transfer member 12 fixed on shaft 11 are rocked clockwise and the lowest order segment 10 fixed on shaft 11 is likewise rocked. When bail 14 is restored counterclockwise it engages arm 12a of member 12 and arm 10a of the lowest order segment 10, thereby entering a " fugitive one " in the lowest order pinions.
