Title: Method and apparatus for growing crustaceans
IPC: A01K61/00
Filed: 1970-12-22
Abstract: 1335572 Culture of crustacea OCEAN PROTEIN CORP 22 Dec 1970 [24 Dec 1969 8 Dec 1970] 60865/70 Heading A1A Post-larval crustaceans occupy individual compartments arranged in rows and stacked in layers in each of a series of interconnected tanks through which they pass as they increase in size. In an initial stage habitats are provided by screens 24 in rectangular tanks 10, Fig. 3, or by strands 140 suspended from diametrical supports 136, Fig. 10, or concentric supports 160 (Fig. 12, not shown) in circular tanks. In subsequent stages compartments in rectangular tanks 12, Fig. 5, are formed by tubes 40 in sloping stacks aligned with the inlet 28 and outlet 32 so that water flowing through will carry the crustaceans into the next tank when required. Alternatively, circular tanks 112, Fig. 13, may be used, the compartments being formed by stacks of plates 180 slotted together. Successive tanks are at lower levels and are connected by tubes 22 or 125 having gates 52 or 192 at each end. Pipes 197 and 200 may be provided to fill and empty the connecting tubes. The water outlets of the first tanks 10 and 110 may be covered by filters 127 and the water from all tanks may be recirculated after filtering. Individual heaters and coolers may be fitted to the water supplies to the tanks or in the tanks themselves. The tanks are aerated by air pipes 29 lying at the bottom.
Patent GB-679414-A (GB)
Abstract: 679,414. Feeding sheets. NILSON, C. E. J. July 7, 1950 [July 8, 1949], No. 17068/50. Class 100 (i). [Also in Group XIX] Sheet-guides.-Guiding means in a card path provided with a funnel orifice and with a guiding point which, upon introduction of a card into the funnel, enters into a hole stamped in the card and follows the card in its movement is characterised in that the guiding point is arranged to be guided by a rail running along the card path. A card is inserted in a funnel 11, passes a guiding point 20 and strikes a tongue 14, both point and tongue being fixed to a yoke 15 slidably mounted on a guiding rail 19. The rail 19 is shaped in its upper portion so that the yoke rests obliquely with the tongue 14 in the card path and the point 20 withdrawn therefrom, and is shaped along its length as rack with which meshes a pinion wheel 17 whose shaft 16 is rotatably mounted in the yoke 15. The card has a hole near one corner so placed that as the card pushes down the tongue 14 the yoke 15 turns forward and the tongue 14 moves out of the card path as the point 20 enters the hole, the point 20 then guides the card in its downward path carrying the yoke down against the action of a return spring wound round the shaft 16 and attached thereto and to the yoke 15. A guiding sheet prevents dis-engagement of the point 20. Only cards appropriately punched and inserted the correct way can push the tongue 14 out of the card path.
Patent GB-739005-A (GB)
Abstract: 739,005. Workmen's time-recorders. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 11, 1953 [May 12, 1952], No. 13082/53. Class 106 (4). Time-recording apparatus in which the stamping position of a card is determined by a hole 52 punched therein at each stamping comprises two hole-finding levers 1a, 1b whose tips are arranged side-by-side so that one or other or both of the tips can independently penetrate the last hole. When a card is pressed down the path 9 it rocks a lever 6 against the action of a spring 7 and removes a stud 8 from the path of levers 2a, 2b so that springs 4a, 4b urge them clockwise about their pivot so that one or both of their tips la, 1b will enter a hole 52 punched in the card when it was last stamped. As a tip 1a or 1b penetrates a hole a surface of its lever 2a or 2b presses the card against a stop-plate 11 engaging it at an angle chosen in relation to the coefficient of friction so that slipping will not occur and the card will be gripped. As a lever 2a or 2b is rocked its tail 3a or 3b engages an end of a coil-spring 12 clasping a shaft 14 loosening the coil and thus freeing the lever 13 so that a spring 23 acting on a two. armed lever 21 draws a bar 18 downwards while an ear 24 of the lever 21 engages the end of a locking spring 25 to free stamping and punching mechanism. When these operations are completed a lever 27 is caused to lift the bar 18 and a tooth 37 of the lever 13 slips beneath an ear 36 of a lever 32 which has been turned into operative position by a cam surface 35 on the lever 6, thus inhibiting further stamping and punching until the card is removed and the spring 12 resumes its locking function. When a card is inserted for the first time it has no hole for a tip 1a or 1b to penetrate and it can therefore be pressed to the bottom of the path 9 to depress a platform 38 down to a stop 39, thus drawing down a bar 17 to release the other end of the spring 12 so that the lever 13 can rock to free the stamping mechanism while an ear 30 on the bar 18 retains the platform 38 against the stop 39 till operations are complete and the parts will be restored correctly even if the card is prematurely withdrawn.

Patent GB-783736-A (GB)
Abstract: 783,736. Calculating-apparatus. VEB TRIUMPHATOR-WERK. Sept. 20, 1955, No. 26852/55. Class 106 (1). A device for attachment to a cam-disc and pin-wheel calculating machine enables an amount registered by the totalizer to be transmitted back to the actuating pin-wheels. The device comprises transmission wheels 2 on a shaft 1 carrying bifurcated arms 3 which may be secured' about the shaft 4, carrying the intermediate wheels 6 for actuating the totalizer, by means of a key 5. The wheels 2 constantly engage the wheels 6 but are normally held in an inoperative position by the action of a spring on the shaft 1. When a re-transmission is to be effected, the shaft 1 is rocked about the shaft 4 to mesh the wheels 2 with teeth formed on the cam-discs 25. A pawl 7 carried by the shaft 1 engages a lug 10 to maintain the wheels 2 in operative position. The re-transmission is effected by a handle and as this completes its movement, a stud moved thereby engages an arm on a shaft 14. An arm 13, also on this shaft, is thus rocked so as to disengage the pawl 7 from the lug 10 and permit the with drawl of the wheels 2. To prevent a re-transmission operation when an amount is set in the actuator, each pin-wheel 20 carries a blocking member 22 urged by a spring 24 into a position in which it blocks movement of the corresponding wheel 2, but cammed into an ineffective position by a stud 26 in the cam disc 25 when the latter is set to zero position.

Title: Binary data transmission method and corresponding encoding and decoding devices
IPC: H04L25/48
Filed: 1978-10-02
Abstract: The invention relates to a method of coding binary data with a recurrence frequency F, the method being particularly suitable when data is to be transmitted via optical fibres. As described, a binary 1 digit is represented by a pulse in one half of the corresponding binary unit, a binary 0 digit being represented by the absence of any pulse in the corresponding binary unit, except that k 0 digits with defined ranks i.e. positions, in a sequence of m successive 0 digits are each represented by a pulse in the other half of the corresponding binary unit, k being less than m. As shown in Figure 1, k = 1 and m = 4 so that in a sequence of four 0 digits, one 0 digit (the k digit) having a defined rank (in this case the last of the four 0 digits) is represented as above. Suitable arrangements for effecting the required encoding and decoding are also described. <IMAGE>

Title: Continuously variable drive systems for vehicles
IPC: F16H37/08
Filed: 1980-02-13
Abstract: A drive system for a motorised vehicle comprises two substantially axially aligned halfshafts 34, 36 which are coupled by a differential gear 38 so as to allow rotation of said shafts in opposite directions. The differential gear, provides rotational drive for one or more road wheels of the vehicle in dependence upon the difference in rotational speeds of the halfshafts. Where the rotational speeds of the shafts are equal the rotational drive is zero while an increase in speed of one shaft over the other will provide drive output, the direction depending on which of the two half shafts is faster. Drive is transmitted from a drive motor 14 of the vehicle to the halfshafts by a friction drive 12 so as to cause the halfshafts to rotate in opposite directions. The friction drive has an endless belt and expanding pulley system 18, 20, 24, 30, 32 for continuously adjusting the rotational speed of said halfshafts relative to that of the drive motor to vary the rotational drive provided by said differential gear. <IMAGE>
