Abstract: 1,092,199. Discharge lamp circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 23, 1965 [July 28, 1964], No. 31447/65. Heading H2H. A discharge lamp 1 in addition to being supplied through an inductor 2 from a first source of between 30 and 100 c.p.s. is fed from second source of at least six times the frequency and not more than twice the voltage through a second impedance 5. It is stated that the addition of the second source will permit a lower voltage difference between the first source and the lamp; also, voltage fluctuations have less effect on lamp current. Details are given in the Specification of relative voltages, frequencies, and series impedances 2, 5 for sodium and 1.p. mercury vapour lamps. A common source 4 may be used for a number of lamps, each having a separate capacitive impedance.

Title: Corrector for the padding indicators in data transmission within a pcm frame
IPC: H04J3/07
Filed: 1972-07-05
Abstract: 1394561 Digital transmission; error correction COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT - ALCATEL 5 July 1972 [8 July 1971] 31537/72 Heading H4P Superfluous bits in a data bit train, called padding bits, are identified by further bits called padding indicators, and if the binary valves of the latter depart from a predetermined sequence, an error is implied which the system corrects by inverting the next padding indicator. A data bit train (lower line Fig. 1a, 1b 1c) is sampled at a higher frequency, upper line, so that a data bit is sometimes sampled twice (a, e). These are the padding bits, and are moved to the third bit position of each triplet of bits. The received train includes as every fourth bit (not seen in Fig. 1) the padding indicator bit. If this is 1, the preceding bit is a padding bit; if it is 0 the preceding bit is not a padding bit; it is data. These padding indicators occur with the pattern 01011, provided there is no transmission error and the frequencies of sample and data trains are within certain limits. Errors produce 3 1's or 2 0's in a row. A combination of two bi-stables (12, 13, Fig. 4, not shown) and logic NAND gates respond to the received train 5, out of which the padding indicators 1B are clocked at 11 by clock HB, to generate four possible patterns with the binary values of A B #A #B. Two 0's in the padding indicator sequence produce a transition of A=0, B=1 to A=0, B=0 which makes the circuit change the second 0 to a 1 in the corrected padding indicator signal IB<SP>1</SP>; and three 1's produce a transition of A=1, B=1 to A=0, B = 0 which makes the circuit change the third 1 to a 0 in IB<SP>1</SP>. Apparent errors following and possibly arising from a correction are allowed to persist for a period of four received bits, and are only corrected then if they have not disappeared.

Abstract: 1480824 Attaching lids to kitchen utensils SEB SA 16 July 1974 [31 July 1973] 31542/74 Heading A4A [Also in Division E2] A lid 1 is hinged on a kitchen utensil 2 by means of an element 3 on the lid 1 pivotably attached to an element 5 secured to the utensil body, one of the elements, 3, comprising at least one pivot 4 engaging a slot formed in the other element, 5, at least one resilient means 8 being provided which means can be retracted under pressure by the pivot 4 to permit snap engagement of the pivot into or out of the slot and which, in one position, at least partly blocks the slot inlet 7a. The resilient means 8, a spring, has two loops 9, 10 of opposite senses, one, 9, co-operating with the stationary part of the spring which is secured to the slotted element 5, the other, 10, ensuring that the movable end of the spring is flexible. The spring's curved, stationary part is held in a recess (7c) Fig. 2 (not shown) formed in element 5, which is a handle of the utensil, the spring being gripped by the utensil body 2. The free end of the spring 8 retains pivot 4 at the bottom of the slot 7 which is formed in a lug 6 of the handle, 5, the handle 5 and jointing element 3 being of moulded plastics material. When the lid is fully open, (1A) Fig 4 (not shown), element 3 is slightly inclined to the vertical, limiting the movement of pivot 4 from slot 7. The lid may be detached from the utensil by moving in a direction towards the utensil's centre after retracting the spring 8. In an alternative embodiment, Fig. 6 (not shown), the stationary end of a spring (18) fits into a slot (15a) in a handle (15). Alternatively, in Fig. 7, (not shown), a spring (28) again has two loops, loop, (30) locking the pivot 4 at the bottom of the slot 7. Again, in Fig. 8 (not shown) a spring (38) has a stop rib, surrounds a lug 6 on the element 5 and extends into a slot (6a) therein.

Abstract: <PICT:0780124/IV (a)/1> <PICT:0780124/IV (a)/2> <PICT:0780124/IV (a)/3> An apparatus for breaking up lumps of cellulose xanthate in a slurry of xanthate and caustic soda solution comprises a vertical cylinder having a circular, rotatable, perforated plate upon which the slurry is deposited, and a roller rotatably mounted so that it lies across a radial line of the plate and is capable of being rotated by frictional contact with the plate, whereby the lumps of xanthate are broken up and forced through the perforations in the plate.  As shown in sectional elevation in Fig. 1, a vertical cylinder 1 carries a rotating shaft 2 to which are fixed paddles 15 and, at the top, a circular grid plate 6 supported by a webbed support 5.  Roller 7 makes radial line contact with plate 6 opposite inlet pipe 20, through which lumps of xanthate 19 and slurry are introduced, the roller being rotated by frictional contact with plate 6.  The roller 7 is freely mounted on stub shaft 8, which is set at an angle of 7 degrees to shaft 2 and fixed to dome 9 of cylinder 1. Plate 6 is composed of a number of segments 10, one of which is illustrated in Figs. 2 and 3, each comprising a number of bars 11 fixed on rods 12.  As the shaft 2 rotates, the lumps 19 are carried into the nip between roller 7 and plate 6 and are thereby crushed and forced through the grid on to lower grids 14, where they are further reduced in size by the action of paddles 15.  If desired, valve 17 may be omitted and cylinder 1 may be directly mounted on mixer 18. Specification 642,270 is referred to.

Title: Means for controlling the stability of an aircraft
IPC: B64C3/54
Filed: 1957-10-15
Abstract: 874,845. Controlling aircraft. HISPANO AVIACION S.A. Oct. 15, 1957 [March 7, 1957], No. 32190/57. Class 4. Means for controlling the stability of an aircraft comprises an auxiliary aerofoil provided on an aircraft at a point removed from the centre of gravity of the aircraft and means to vary automatically the angle of attack of the aerofoil, in accordance with variations in the lift force acting on the aerofoil and accelerations acting on the aircraft transverse to its longitudinal axis, to apply lift to, or to simulate the application of weight, at that point to obtain a virtual shift in a desired direction of the centre of gravity of the aircraft. The auxiliary aerofoil is preferably located at the forward end of a fuselage whereby adjustment of the angle of attack of the aerofoil produces an aerodynamic force equivalent to the one which would be obtained with a weight placed in the same position on the fuselage as the auxiliary aerofoil, this being stated to cause a virtual shift in the centre of gravity of the aircraft. The aerofoil 5 is mounted for pitch adjustment about an axis 6 upon a rod 7 mounted in bearings for axial movement, the aerofoil being adjusted for pitch by an actuator 4 controlled by a comparator 3 which receives signals from an accelerometer 1, which detects accelerations transverse to the longitudinal axis of the aircraft, and a unit 2 which detects, by movement of rod 7, the magnitude and direction of the aerodynamic force acting upon the aerofoil 5. In one embodiment rod 7 is balanced in a neutral position by springs and it carries a valve body, the movable piston of which is actuated by a spring-balanced mass responsive to accelerations on the aircraft, the valve controlling the operation of actuator 4. Other embodiments are described comprising linkages for supporting the aerofoil in which the angle of attack of the aerofoil may be adjusted by either making the aerofoil rigid with one element of the linkage or by adjusting the whole linkage by an actuator.
