Patent GB-1535549-A (GB)
Title: Method of purifying waste water
IPC: C02F11/04
Filed: 1976-04-23
Abstract: In the purification of carbohydrate- and/or protein-rich effluent, the effluent is treated in an anaerobic stage (1), methane gas formed being discharged (2). The sludge-containing water formed is subjected to a sludge separation (3), a first sludge concentrate resulting which is returned to the anaerobic stage (1). The water separated off is treated in an aerobic stage (7) and the sludge-containing water formed is subjected to a sludge separation (8) to form a second sludge concentrate, of which a part is returned to the aerobic stage (7), while excess is passed back to the anaerobic stage (1). A part of the first sludge concentrate is discharged for disposal. When the process is applied for example to effluent from sugar, starch or canning factories, the two biological processes proceed with great stability and with good purification action. Moreover, the amounts of biological sludge are only a fraction of the conventional amount of sludge. The solids are easily removed for example by sedimentation from the effluent. <IMAGE>

Title: Security devices and methods of operation thereof
IPC: G07C9/00
Filed: 1974-04-16
Abstract: 1456138 Locks D M SABSAY 16 April 1974 16649/74 Heading E2A The memory of an electronic lock is automatically reset to a new code number when a key having both the new code and the superseded one is inserted. Each time a key is used, two numbers are entered, a new key number and an "authorisation" number which is the superseded number. If the key number is found to match the combination previously stored in the memory, the lock is opened in the normay way. But if they do not match, a comparison is made between the entered authorisation number and the previously stored combination, and if these numbers correspond, the lock memory is reset to the entered key number. Then the first comparison step is repeated, and the lock is opened. The old code number will now not release the lock. As shown, a key 100 of plastics material has binary numbers encoded thereon at 107 and 108 by means of magnetic spots, coloured ink or punched holes 101. The key also has coded areas 104, 105 whereby it may be inserted either-side-up into a key reader 114 provided on a door lock 116. If the key number matches the previously stored combination number, memory and decoding circuits 115 effect unlocking of the lock. In making a new key, a new key number is entered via an input-output device 120 and a previously assigned key number, retrieved by a computer 121, is transmitted to the key producer 124 which encodes the previous key number as the present authorisation number. A randomizer 126, i.e. a high-rate free-running counter, presents to the computer a randomly selected number which is encoded on the key as the new key number. The key may be encoded to give access to a predetermined number of locks.

Tyres, elastic, special apparatus for making.-In a machine having a pair of " stitching" " rolls 18 for laying-down the fabric on a rotating mandrel C, means are provided whereby the inclination of the rolls is automatically adjusted as these travel over the mandrel; such adjustment being commenced at any predetermined position of the rolls with respect to the mandrel. The devices are supported on a carriage 2 which is moved towards and from the axis of the mandrel by means of a hand-wheel 6 and screw 4, with limiting stops. The rolls 18 are normally forced towards one another by pressure-fluid admitted to the cylinders 33, the piston-rods 31 of which actuate bell-cranks 29 pivoted to extensions 27 of the cranked arms 11 supporting the rolls 18. as seen in Figs. 1 and 2. The mechanism for altering the inclination of the rolls comprises arms 19 connected by links 20, 21 to the outer ends of a pair of bell-cranks 24 the inner ends of which engage angled slots 9 in a slide 8. At the commencement of an operation, the slide 8 is caused to travel with the carriage 2 through the engagement of a spring-pressed pin 43 in a bushing 42 in the slide. During this movement the pins 26 on the levers 24 remain at the inner ends of the slots 9, as shown in Fig. 1. Keyed to the slide 8 is a rod 39, one end of which is connected to the piston of a fluid-pressure cylinder 38, the' other end being fitted with an adjustable head 48 adapted to abut against a fixed stop 49. This abutment causes a detent 41 pivoted on the rod 39 to rock and thereby depress the pin 43 clear of the slide 8, the travel of which is thus arrested. On the further movement of the carriage 2, the pins 26 traverse the slots 9 to effect the angular adjustment of the rolls 18, as shown in dotted lines in Fig. 1. The cylinders 33 are fitted with escape-valves 37, springs 50 maintaining the inward pull on the rolls 18. The approach of the rolls to one another may be limited by means of adjustable stop sleeves 53, Fig. 3, screwed into the ends of the cylinders 33, abutments 55 being provided on the piston-rods.

Title: Improvements in electrical relays
IPC: H04W88/02
Filed: 1921-06-24
Abstract: 185,875. Ransford, R. B., (Soc. Fran- þaise Radio-Electrique). June 24, 1921. Systems employing valve amplifiers.-A relay device comprises a three-electrode valve 1, Fig. 1, connected to two oscillatory circuits 2, 3, and a variable absorbing circuit such as a microphone and inductance 12, 13, coupled to one of the circuits 2, 3, the arrangement being such that normally the valve generates oscillations at the frequency of one of the circuits 2, 3, but on operation of the absorbing circuit, generates at the frequency of the other. If the frequencies are widely separated currents will occur mainly in the circuit tuned to the oscillations generated. The change over, once effected, persists unless some operation, such as earthing the oscillatory circuit, is effected. This may be done as shown by the operation of a relay 10 in the circuit. The absorbing circuit may comprise a magnetic amplifier or a triode valve arranged either to amplify or to rectify. In making use of the device signal lamps may be included in the circuits 2, 3 so that one or other glows according to whether the absorbing circuit is operative or not. Hot wire or electrodynamic ammeters such as 10, 11 may be arranged in the circuits and made to close the circuit of a relay. A directcurrent instrument such as 15 may be inserted in the anode circuit of the valve 1 when considerably more energy is used in oscillating at one frequency than at the other. In using the apparatus in a device for recording signals, incoming signals affect the absorbing circuit 12, 13 for example by having the receiver placed next to the microphone 12. The contact apparatus 10 consists of a small quick acting relay which may itself carry a pen. The second oscillatory circuit 2 is periodically earthed by a uniformly rotating commutator, thus during the reception of a signal the contact of relay 10 and the pen move backwards and forwards a number of times depending on the speed of rotation of the commutator and the length of the signal. During spaces the relay is stationary.
