Title: Apparatus for the selection or correction of data in an electronic watch
IPC: G04G5/00
Filed: 1981-02-11
Abstract: The apparatus comprises commutating means 10 operated by the rotation in one direction or the other of the watch spindle 1, which rotation produces trains of commutation pulses that are phase-displaced with respect to each other. The watch circuit produces from the trains of commutation pulses a signal indicating the direction of rotation of the spindle and produces selection or correction pulses. The commutating means comprise two cams 2, 3 mechanically coupled to the rotatable spindle 1, angularly displaced one with respect to the other and arranged to actuate two resiliently flexible strips 4, 5 which are fixed at one of their free ends and the other free ends of which are alternately brought into contact with and removed from respective fixed contacts 7, 8. The watch circuit can include means for rendering ineffective a predetermined number of selection pulses at the beginning of the rotation of the spindle in one direction or the other.

Title: Measuring System for Spraying Equipment
IPC: G01F9/00
Filed: 1981-03-31
Abstract: A system for determining the spray density of liquid being distributed by mobile spraying equipment uses a first count 3 of pulses representing the flow of spray medium, from transducer 1, and a second count 4 of pulses representing the distance travelled, from transducer 2. In order to derive the spray density independently of time, a comparator 6 is provided to reset a store 5 when the accumulation of pulses in counter 3 reaches a predetermined count 7. After division 8, the spray density is displayed either directly 12 or as a relative departure from a set value 16. Boom width and other constant factors can be applied to give values such as total volume sprayed 19, total distance 22 and area 24 covered. The distance pulses can also be used with a separate clock 25 to give a speed indication 35. <IMAGE>

Title: Peristaltic pump
IPC: F04B43/12
Filed: 1981-07-30
Abstract: The peristaltic pump comprises several cylinders (5) rotated by a planetary gearing from a central gearing (3); these cylinders are rolling over at least one hose which conducts the fluid through compression of the free section of the hose. There is provided a counter-pressure body (11) passing the hose (10) against at least a cylinder (5); this body is held on a base plate (15) so as to slide in a radial direction with respect to the central gearing (3); it is taut by at least one spring towards the central gearing (3) Upon replacing the hose, the new hose is thereby located only within the counter-pressure body and, by tightening the counter-pressure body by means of the springs, a sufficient pressing is achieved for ensuring a functional efficiency of the pump. Furthermore, the tolerances in the mounting and the hoses are compensated by the counter-pressure body acting as a spring.

Title: Acoustic echo-sounding system
Inventor: GLASGOW JOHN ARTHUR
IPC: G01S15/89
Filed: 1986-11-22
Abstract: An echo-sounding system illuminates an area of sea-bed with acoustic energy which is received at two receiving transducers 4, 5. The relative phase of the transducer outputs indicates the direction of a feature from which an echo is received but there is a directional ambiguity due to a lobe structure of the system's sensitivity pattern. This ambiguity is resolved by transmitting at two or more different frequencies giving respective different lobe structures. The frequencies are transmitted alternately or simultaneously and Filters 6, 8, in the receiving means separate the resulting signals. Analyser 10 calculates range and direction. <IMAGE>
