Abstract: The trimmer Hall sensor is used in the field of instrumentation engineering, weak polar magnetometry and microsystems, in contactless automation, instrumentation construction, the power industry, theelectrical industry, in military warfare industry, and others. It eliminates basic deficiencies of the analogous solutions - high offset values in the individual output channels and the essential temperature drifting. The sensor comprises semiconductor wafer (1) of mixed type conductivity, on one of the sides of which two pairs of identical rectangular ohmic contacts are made at equal distances, fitted parallel to their long sides. Contacts of one of the pairs are sectioned into two equal parts (2, 3 and 4, 5), parts (4 and 5) of one of the sectioned contacts are fitted between the non-sectioned rectangular ohmic contacts (6 and 7). On the short sides of contacts (6 and 7), at equal distances from them, one pair each of Hall contacts (8, 9 and 10, 11) are formed. Parts (2, 3 and 4, 5) of the sectioned contacts are connected to the end outputs of two trimmer (12 and 13), the middle outputs of which are connected across load resistors (14 and 15), respectively, to the two outputs of a current source (16). Each of contacts (6 and 7) across two loads resistors (17, 18 and 19, 20) connected in series, respectively, is connected to both outputs of the current source (16). The two equal parts (2, 3, and 4, 5) of each of sectioned ohmic contacts are coupled to the respective input (21 and 22) of the first amplifying unit (23), the output of which is output (24) of the component of the magnetic field (33), orthogonal to the surface of wafer (1). The pair of Hall contacts (8, 9 and 10, 11), fitted on the short sides of the two contacts (6 and 7) are connected to the appropriate input (25 and 26) of a second amplifying unit (27), the output of which is output (28) for one of the parallel to the surface of wafer (1) component of magnetic field (33). The middle output of each of the two trimmers (12 and 13) and the common point of each resistor (17, 18 and 19, 20) connected in series are connected to the appropriate input (29 and 30) of a third amplifying unit (31), the output of which is output (32) for the other component of the magnetic field (33), parallel to the surface of wafer (1). The external magnetic field (33) has an arbitrary direction across the semiconductor wafer (1).

Abstract: A system for determining a leakflow of a vacuum system of a vacuum filter comprises a controller (101) for adjusting speed of a filtration media of the vacuum filter and/or for adjusting supply rate of slurry onto the filtration media. The system comprises a pressure sensor (102) for determining pressure difference affecting over the filtration media and a layer of the slurry carried by the filtration media, and a device (103a, 103b) for determining flow rate through a vacuum pump that maintains the pressure difference. The speed of the filtration media and/or the supply rate of the slurry is/are adjusted so that the slurry is fully saturated by liquid along a whole filtration area affected by the pressure difference. Thus, fluid flow through the layer of the slurry is negligible and therefore the determined flow rate is indicative of the leakflow of the vacuum system.

A seal 10 for a rotary shaft 16 comprises a sealing ring 58 located in an annular recess 40 in a housing 28 and having at one end an axially extending lip portion 62 with a conical external surface 63, a radial flange 66 at the other end and a cylindrical external surface 72 between the lip portion 62 and the flange 66, a wedge ring 78 which surrounds the lip portion 62 and urges it into sealing contact with the shaft, and a support ring 74 that overlies the surface 72 and is urged axially by a corrugated spring washer 86 between it and the wedge ring 78 to thereby press the flange 66 into sealing engagement with a wall 42 of recess 40. The ring 78 is urged against the lip portion 62 by a garter spring 82 and the washer 86 presses the ring 82 against a back-up plate 84. A pin projecting inwardly from the housing 42 engages an axial slot in the ring 74 to prevent rotation of the latter. The sealing ring 58 and the wedge ring 78 may be of glass-filled " Teflon " (Registered Trade Mark) and the support ring 74 may be of metal. In a modification, Fig. 4 (not shown), the seal is retained in the housing 112 by a pair of split rings 118 and the radial flange 146 of the sealing ring 134 is inclined. In a further modification. Fig. 6 (not shown), two seals 110 are arranged backto-back separated by a spacer 174 vented to atmosphere.

Abstract: 1,053,505. Securing hubs on shafts. J. HOCHREUTER. March 15, 1965 [March 23, 1964], No. 10803/65. Heading F2U. A pulley or like member 1 is secured on a shaft by a split conical sleeve 2 engaged within a tapered bore in the member, the complementary conical surfaces having radial stepped portions 4, 5 for the passage of tightening bolts or screws 6. The sleeve 6 may be withdrawn by removing the bolts 6 and rotating them in separate threaded holes passing through the step portion 4 and with their ends bearing against the step 5.

Abstract: 1,225,187. Sulphur dioxide. ALLIED CHEMICAL CORP. 7 Aug., 1968 [11 Aug., 1967], No. 37649/68. Heading C1A. [Also in Division C2] Sulphur dioxide is obtained as a by-product of the reaction of sulphur trioxide with fluoroalkyl iodides of the formula R(CH 2 )mI wherein R is either (a) a haloalkyl group having up to 20 carbon atoms in which the free valencies of the terminal carbon atoms are satisfied by H, F, Cl or Br and the free valencies of all other carbon atoms are satisfied by F or CI or (b) a per(fluoro- or chlorofluoro-)cycloalkyl group having up to 6 ring atoms, each carbon atom in (a) and (b) being fluoro-substituted, and m is an integer of up to 3. The S0 2  is obtained from the evolved gases by a cold-trap.

Abstract: 1,227,762. Catalytic fuel cell electrodes. GENERAL ELECTRIC CO. 29 April, 1968 [1 May, 1967], No. 20194/68. Heading B1E. [Also in Division H1] A catalyst composition comprises an alloy of Pt and at least 20 wt% is preferably dispersed on a support material which may be B 4 C 3 , graphite, tantalum or titanium boride or a metal silicide. The compositions may also contain a binder such as PTFE and can be used in fuel cell electrodes. The formation of compositions by drying a paste of B 4 C 3  or graphite in an aq-solution of Pt(NH 3 ) 2  (NO 2 ) 2  or H 2 PtCl 6 +IrCl 3 , grinding, reducing the material under H 2  at 125‹C, and mixing to a paste with a PTFE suspension is described. The paste is applied to a Pt-mesh to form the electrode.
