Title: Skis
IPC: A63C5/048
Filed: 1976-05-21
Abstract: 1505092 Skis H FORD 21 May 1976 [23 Oct 1975] 43682/75 Heading A6D A ski has a predominantly convex undersurface, when viewed along the ski axis, and has a blade 52 secured to each side of the ski adjacent the boot position, each blade being parallel to the ski axis and extending downwardly to terminate in a cutting edge, the cutting edges of the two blades being at approximately the same level as the lowermost portion of the convex undersurface. The convex undersurface may have a constant radius of curvature (Figs. 3, 4) or may vary across the width of the ski in the manner shown in Fig. 11. The broken line on the right hand side of Fig. 11 illustrates the contour of the ski along most of its length. The solid line shows increased thickness in the region of the blades. The left hand side of Fig. 11 shows the mounting for the leading edge of the blade. The leading edge of each blade is upwardly curved. The trailing edge 10 is square cut. The outwardly facing surface of each blade is curved inwardly downwardly. The inwardly facing surface of each blade is either vertical (Fig. 4) or inwardly upwardly curved (as shown). The blades may be formed integrally with the ski body, in which case they may incorporate metallic reinforcement (Fig. 5). Separately formed blades may be secured to the ski body by bolts extending across the width of the ski (Fig. 4), screws 56 or bolts formed integrally with the blades. Locating dowels may also be used. Forward and rearward sections of the ski body may be of shallow dish form filled with foam (Fig. 12). Alternatively, the whole length of the ski may be of foam-filled shallow dish section with the middle (boot or blade) portion having a flat upper plate covering and secured to the dished lower portion (Fig. 13).

Title: Code recognition
IPC: G06K7/10
Filed: 1972-09-21
Abstract: 1449605 Label reader UNILEVER Lid 19 Sept 1973 [21 Sept 1972] 43750/72 Heading G4M  Labels on articles, e.g. in warehouse or automated or computer linked control systems having parallel rows of digital code markings, each row containing one digit, are reads using a television camera having its line scan aligned with the rows. The code used has wide or narrow bars which may be symmetrical about a centre line (Fig. 1 not shown) the narrow bars indicating a zero in a bit position and the wide bars a one. Each decimal digit may contain a wide space the position of which indicates the decade of the digit, e.g. a wide space between bits 3 and 4 indicates hundreds and between 1 and 2 indicates units. The codes may be non- symmetrical (Fig. 2 not shown) using similar wide and narrow bars but with non-symmetrical wide and narrow spaces to indicate the direction of reading. Coded articles A on a conveyer are scanned by the television camera C which feeds a conditioning unit D which removes high and low frequencies and noise and triggers a square wave having a background or white level and a mark or black level. A decoder E produces '0' and '1's from the video signals. In the decoder when a signal level changes a shift register is reset and a pulse is fed in. At the next signal level change the stage reached by the signal determines whether the mark is ignored because the signal is not shifted far enough, whether it is a '1' because the signal is situated betweeen predetermined stages, whether a error exists because the signal is between two further predetermined stages, whether the signal is a '1' for similar reasons or whether the signal has shifted too far and is an error or the end of the train. The binary signal is fed to the first half F of a shift register and sequentially proceeds into the second half. When the registers are full their contents are compared and if they differ a fault is diagnosed. If the comparison is correct the order determined by the wide space is obtained and the character is fed to memories J or K. The television scan is arranged so that at least three successive scans pass through each row and so three successive decodings of the data are compared using memories J,K and comparators L,M. I is a memory selector determining which memory the data enters. The fully decoded and correct signal is passed to units N and P for storage on tape or for use in a computer. Successive lines may use different codings which are fed to different decoders on reading.

Title: Low power sealed resonance lamp
IPC: H01J65/04
Filed: 1974-10-10
Abstract: 1487594 Discharge lamps R A YOUNG 10 Oct 1974 [12 Dec 1973] 43903/74 Heading H1D A resonance lamp comprises a closed housing 11 with a re-entrant element 15, a conductor 17 in the element, a window 34 in the housing, a conductive earthed coating on the outside of the housing, a hollow arm 19 enclosing a getter 21 such as U or Ba, another hollow arm 27 enclosing a source 29 of the substance to be examined, and a pure rare gas, or an inert gas, filling the housing. The output of an oscillator 18 is applied to the conductor 17 to excite the lamp. Arm 19 has a heater 25 for the getter 21, and arm 27 has a heater 33 for the source 29. The arms have gas permeable barriers 23, 31 made of, e.g. glass frit. The end of housing 11 is closed by a window 34. To provide an oxygen resonance lamp, the housing 11 is evacuated and filled with He at 1-2 torr. The getter is U and the source 29 is an oxygen source such as MnO 2  or KMnO 4 . The frequency of oscillator 18 is 150-600 MHz. The He must be of high purity. For a hydrogen resonance lamp, a mixture of U and UH 3  is used as source and getter and only one arm is required on the housing. In the oxygen lamp, the He filling may be replaced by N 2 .

Abstract: 1,154,783. Adding, multiplying, integrating operational amplifiers. INSTITUT FœR REGELUNGSTECHNIK. 27 Sept., 1967, No. 44016/67. Heading G4G. [Also in Division H3] In an e.g. transistorized range of operational amplifiers which may e.g. be used for integration, comprising amplifiers Ve 1  to Ve n  with computing feedback impedances Zo 1  to Zo n  and input shunt impedances Zi 1  to Zi n ; the error input currents are compensated by connecting to input summation points S 1  to S n  over compensation resistances RK 1  to RK n , the respective currents derived from the output of similar additional amplifier Ve n +  1  with zero input and a feedback resistor RK from output to input (Fig. 2). The additional and operational amplifiers may be positioned in a temperature-controlled metal block. The individual compensating currents may be regulated by a variable resistance in series with a fixed resistance constituting RK i  (Fig. 3, not shown) or by variable potential dividers across the output of the additional amplifier respectively connected to the summation points of the operational amplifiers over fixed resistances (Fig. 4, not shown). Alternatively, where each operational amplifier is transistorized, the summation point may be connected to the base of an input transistor whose collector resistance comprising fixed and variable resistances in series may be adjusted to zeroize the input error current (Fig. 5, not shown).

Title: Manufacture of chlorine
IPC: C01B7/05
Filed: 1963-11-07
Abstract: Chlorine is produced by contacting NH4Cl with reaction masses composed of granular inert supports impregnated with chlorides or oxides of iron, with copper or cadmium chlorides and with alkali metal chlorides and flowing by gravity in moving beds through superimposed reaction chambers wherein occur successively reduction, chlorination and oxidation of the masses, at least part of the NH4Cl being introduced in the solid form into a moving bed before the oxidation zone.  The process may be carried out in apparatus of the type illustrated in Specification 1,005,771, modified by an inlet into the conduit between chambers 1 and 2 through which NH4U may be injected in finely divided form, by means of a pneumatic device, and together with the alkali metal chloride if desired.  Additional NH4Cl may be introduced into chamber 2 as vapour from a sublimer.  A table is given showing the effect of varying the proportion of NH4Cl introduced in solid form.

Title: Improvements in or relating to high-frequency surgical apparatus
IPC: A61B18/12
Filed: 1962-11-28
Abstract: 1,014,995. Electromedical apparatus. SIEMENS-REINIGER-WERKE A.G. Nov. 28, 1962 [Nov. 29,1961], No. 45049/62. Heading A5R. In high-frequency surgical apparatus in which flow of protective gas is maintained around the active electrode, a sensitive electrical element positioned in the gas stream ensures that there is no output from the H.F. generator unless the gas is flowing. In one form, the operation of the apparatus is initiated by depressing a foot switch 1 which energizes a relay A and thereby opens an electromagnetic valve 5 to allow gas to flow from a cylinder 7 to the operating handpiece 10. It also passes current through a resistor 20 having a negative temperature coefficient so as to impose a delay on the energization of a relay B which, at contact b 1  prepares a circuit for energizing the oscillation generator 17. The handpiece 10 incorporates a negative temperature coefficient resistor 12, through which current is flowing from a source such as 24, and the cooling caused by the flow of gas causes its resistance to increase and raise the potential of the lower junction of resistor 25 sufficiently to trigger a monostable circuit 13 and energize a relay C which completes the control circuit of the generator 17. If the gas supply fails, the resistance of resistor 12 decreases, the circuit 13 returns to normal and the oscillation generator 17 is cut off. It a fault, such as breakage or damage, occurs in the circuit including the resistor 12 the full voltage of the source 24 is then impressed on the input of a low-sensitivity amplifier 14 which thereupon energizes a relay D to interrupt the circuit of relay B and cut off the oscillation generator.

Abstract: 1,262,204. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. 3 Sept., 1970 [5 Sept., 1969], No. 44053/69. Heading A3B. In making a shoe having no insole in the forepart region the lasting margin is wiped across the bottom of the last 6 in this region and is consolidated in its wiped condition by the hardening of thermoplastic material 14 previously applied to the last bottom, any bond formed between lasting margin and the last bottom being easily breakable. The last bottom may have a metal sole plate which does not bond to the thermoplastic material or may be coated with a release agent. As described an upper 10 is lasted in conventional manner in the heel and waist region to a part insole 2 having a shank stiffener 4. Thermoplastic adhesive 14 e.g. a molten polyester adhesive is then applied to the forepart region of the last bottom and the lasting margin is wiped inwardly, the thermoplastic material flowing between the pleats and folds of the inwiped lasting margin so that when it hardens the lasting margin is held in its wiped position. The lasting margin is then roughened and an outsole (not shown) is provided. The outsole may be preformed and bonded to the lasted upper by adhesive or may be moulded directly onto the bottom of the lasted upper. The last is then removed from the shoe and an insock is placed inside the shoe.

Title: Adjusting device for adjusting the relative positions of two members
IPC: A47C3/28
Filed: 1962-11-22
Abstract: 1,010,458. Seat adjustments. H. P. DOETSCH. Nov. 22, 1962 [Nov. 27, 1961; Oct. 30, 1962], No. 44252/62. Headings A4H and A4J. [Also in Division F2] A device for adjusting the height of a seat comprises two tubes 1, 2 telescopically slidable one within the other. Tube 2 accommodates a reservoir 3 filled with a highly compressed gas. Tube 1 is closed at one end and rigidly connected to the legs 13 of a chair. A damping piston 14 is fixed to the base of the tube 1 and inserted in the reservoir 3 in a gas tight manner. The piston may be braked directly by the gas or it may be associated with a fluid filled damping cylinder 15. The reservoir 3 carries a frustum 7 so dimensioned that a tapering annular space is formed between the outer surface of the frustum and the inner surface of the tube 2 to receive wedges 6. The tube 2 has longitudinal slots 5 in the region of the frustum 7 to facilitate its deformation. To keep the wedges 6 in the same radial place in every position of the wedging device, they are mounted, as shown in Fig. 2, in a guide 8 in such a way that they can move freely in a radial direction but in the axial direction are secured in position relative to the guide 8. A compression spring 12 is mounted between the end of the reservoir 3 and the guide 8. The tube 2 carries a rotary bearing 18 rigidly connected to a chair seat plate 19. An arm 21 of a lever 20 engages an annular groove 22 in the reservoir 3. To adjust the height of the seat plate 19, an end 23 of the lever 20 is moved upwards to release the wedges 6. The weight of a person sitting on the chair will lower the seat plate. When the seat has reached the required height the end 23 of the lever 20 is presed downwardly so that the reservoir 3 is moved axially relative to the telescopic tube 2. This displacement moves the wedges 6 into the narrowing space between the frustum 7 and the tube 2 so that the latter is pressed firmly against the tube 1 and the seat plate locked in adjusted position.
