Title: Apparatus for controlling the frequency of an oscillator
IPC: H03K23/66
Filed: 1973-03-14
Abstract: 1386935 Automatic frequency control; radio receiving circuits LOEWE OPTA GmbH 14 March 1973 [10 March 1972] 12166/73 Headings H3A and H3Q The frequency of an oscillator is controlled by means of a constant frequency source, a programmable multi-stage frequency divider having input means connected to the oscillator and a phase comparator having one input coupled to the oscillator and the other to the output of the frequency divider its output controlling the frequency of the oscillator: a multi-stage pulse counter controlled by clock-pulses from a clockpulse generator and having its stages serially interconnected is provided, together with means selectively connecting each stage of the counter to a respective stage of the frequency divider, and also visual indicator means selectively con-. nected to output means of each stage of the counter. Variable frequency oscillator 1, Fig. 1 feeds into a preliminary frequency divider 2 of fixed ratio the output from which is applied to a three stage digital frequency divider 3, the output from which comprises one input of phase discriminator 5. The second input to phase discriminator 5 is derived from a crystal oscillator 6 over frequency divider 5 of fixed ratio. A frequency control voltage is derived as output from phase discriminator 115 and is applied over lowpass filter 11 to a varactor diode controlling the frequency of oscillator 1. Each stage, e.g. 4a of digital frequency divider 3 is associated with a corresponding counting decade 12a &c comprising a counter 15a &c. driven from clock-pulse generator 13 or the output from the preceding counter, as the case may be, and a store 16a &c. The clock pulse generator 13 is set in action by means of switch 14: the circuit is arranged so that it can count both upwards and downwards, so that the time to reach a new signal is reduced to a minimum. In a modification (Fig. 4, not shown) the oscillator comprises the local oscillator of a radio receiver the clock pulse generator is activated via an automatic change over switch whereby on interception of a signal carrier the output from a frequency discriminator stops the clock pulse generator upon accurate tuning; i.e. zero output from the frequency discriminator. Frequency dividing stage control circuit.- BCD counting decade 15a, Fig. 2, is controlled via inputs a, b from the clock pulse generator; its output is connected to electronic switch 17 and also to store 16a. The switch 17 selects an output either from counter 15a or from store 16a from which four different outputs can be obtained by means of selecting inputs Aa-Ad. The output from switch 17 passes to output terminals A-D and also to a decoder 18 which operates a visual indicator 19 in the form of a 7-segment numerical display tube. The Specification describes a practical embodiment (Fig. 3, not shown) and also a clock pulse generator (Figs. 5, 6, not shown).

Title: Watercraft especially useful for the recovery of oil
IPC: E02B15/04
Filed: 1970-03-18
Abstract: 1302386 Ships WORTHINGTON CORP 18 March 1970 [2 Feb 1970] 13160/70 Headings B7A and B7V Acatamaran, particularly for oil slick recovery, is powered by two water jet engines 18 and 20 from which thrust can be diverted to thrust outlets 44, 46, 48 and 50, which outlets can be opened and closed selectively from a control panel 22 to move the boat sideways or to turn it about a vertical axis. Each water jet engine is powered by a propeller, Fig. 4 (not shown), which is driven through a centrifugal clutch 240 by a rotary piston engine 72. Water is taken in through an inlet protected by slats 232 and is passed to an outlet 84. The size of the outlet opening and thus the forward thrust on the boat is controlled by a pivoted gate 88 which is operated from the control panel by a sheathed cable 238. The outlet regions of the water jet engines are connected to the thrust outlets 46 and 50, to reverse thrust outlets 102, and, through ducts 52 and 56, to the thrust outlets 44 and 48. The outlets are controlled by flap valves, e.g. 108, 118 and 122, which are operated by sheathed cables from the control panel. Each jet engine includes a propeller housing 80 releasably secured to a one-piece aluminium casting which is itself secured to a hull of the boat and which mounts the engine 72. Removable cover-plates 236 give access to the water passageways in the jet engines. Each member 70 includes a hollow forward section filled with buoyant solid foam. The boat has a rudder 98 whose shaft (214), Fig. 7 (not shown), turns in a block (200) which is pivoted about a horizontal axis to support brackets (190, 192). Shear pins (210) normally maintain the block fixed relative to the brackets, but, if the rudder encounters an obstacle, the pins break allowing the rudder shaft to pivot upwardly. The oil recovery system includes a roller 25 which has an oil-absorbent surface and which is rotated in the water by a motor 29. A presser roller 33 squeezes oil from the roller 25 into onboard storage devices (not shown). The two hulls of the catamaran act to channel oil towards the roller 25 and the channelling effect is increased by bow wings 26. The catamaran may have alternative or additional functions, e.g. trash gathering, weed cutting, fire fighting, oil boom laying and fishing.
