Title: Gas sensing element
IPC: G01N27/12
Filed: 1977-01-18
Abstract: 1518470 Gas sensing element NITTAN CO Ltd 18 Jan 1977 [29 Jan 1976 12 April 1976] 01976/77 Heading G1N A gas sensing element comprises a pair of electrodes 1, 2 connected to a body S formed of a sintered oxyacid salt semi-conductor composition which changes its electrical resistivity according to ambient gas concentration. Preferably the oxyacid salt is a silicate, chromate, molybdate, tungstate or phosphate. An oxide or carbonate of a metal such as Sn, Nb, La or In is included as a sintering suppression agent so that, after firing, the salt product has a porous surface. An oxide of Pt, Pd, Rh, Ru, Au, Ag, Zr, In, Ni, Cr, Co or Mn is added as a catalyst to improve gas selectivity and sensitivity. To reduce the cost of the associated circuits the resistance of the element is reduced from the range 10<SP>7</SP> - 10<SP>10</SP> ohms to about 10<SP>5</SP> ohms by inclusion of carbon. A positive temperature coefficient resistor is adhered to the body to provide a heater H. Figures 6, 7 (not shown) demonstrate the higher sensitivity to hydrogen of the element compared with a commercially available metal oxide semiconductor element and Figs. 8, 9 (not shown) demonstrate the relative insensitivity of the former compared with the latter for variations of ambient relative humidity and temperature.

Title: Process and device for full-cell impregnation of timber or articles thereof
IPC: B27K3/08
Filed: 1943-02-06
Abstract: 571,816. Impregnation of timber. TRIGGS, W. W. (Bolidens Gruvaktiebolag). Feb. 6, 1943, No. 2003. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug 9. 1943] [Class 140] In a process for the full-cell impregnation of timber with preservative liquid by placing it in a closed cylinder, filling the cylinder with a liquid, pumping out said liquid and so creating a vacuum in the cylinder, and after an interval filling the cylinder with preservative liquid which is then forced into the material by pressure, the same pump or pumps are used for evacuation transfer of liquid, and compression. The two liquids may both be preservative liquids, e.g., containing arsenic compound as described in Specification 468,378. Apparatus for the impregnation may comprise a cylinder A for housing the timber, connected through a valve B and pump D with a tank C for the liquid, and having an outlet valve E. In operation, with valves B and E open, cylinder A is filled with liquid from tank C by pump D. Valve E is closed, and the liquid is pumped back by D into C, leaving a vacuum in A, valve B being then closed. To improve the vacuum, A may if desired be refilled with liquid from C, air that has been sucked out of the timber being let out through E, and A again evacuated by D. After an interval, B is opened and A again filled with liquid from C by D, any air in A being let out through E as before. The liquid in A is compressed by D and forced into the material, any surplus being then pumped back into C either with E open or, if subsequent dripping is to be reduced, with E closed so as to subject the material for a short time to a vacuum by pump D before admitting air at E. In an alternative apparatus, tank C is at a higher level than cylinder A so that liquid may flow from it under gravity into A through a valved pipe, and the pump D is not used for filling A with liquid. Tank C may be placed at a lower level than A. The plant may be provided with known arrangements for drying, steaming &c., and for heating the liquid.

Title: Improvements relating to ratchet hoists
IPC: B66D3/14
Filed: 1947-11-12
Abstract: 684,006. Ratchet hoists. COLUMBUS McKINNON CHAIN CORPORATION. Nov. 12, 1947. [Nov. 13, 1946] No. 2238/51. Divided out of 683,943. Class 78 (v). In a ratchet hoist fitted with selfsustaining gear of the type comprising a friction brake connecting the load wheel shaft to a ratchet engaged by a releasable pawl, the pawl is fitted in a bore in a boss in the frame of the hoist, and may be pulled out against the bias of a spring disposed in a bore in the pawl and bearing against a fixed pin extending through a slot in the outer end of the pawl: it may be locked in this position by causing a shoulder on the pawl to ride on an abutment on the boss. When the driving ratchet 46, 48, Fig. 1 of the ratchet hoist illustrated is driven in the hoisting direction it is automatically clutched to a plate 26 on the shaft of the load wheel 24 by friction discs 36, 44 and a ratchet wheel 40 forced towards the plate 26 by the driving ratchet 46, 48 when a helical cam surface 52 on the ratchet 46, 48 rotates relatively to a corresponding surface on a face cam 56 keyed to the shaft. A pawl 88, Fig. 3, in a bore 86 in the frame of the hoist is urged by a spring 95 into engagement with the ratchet wheel 40 to prevent reverse rotation of the load wheel and the driving ratchet when the drive to the latter is discontinued. The spring 95 abuts on a pin 96 threaded through abutments 98 (see also Fig. 2) which are normally received by a slot 92 in the head 90 of the pawl but which engage the head to hold the pawl when it is pulled out of engagement with the ratchet wheel 40 to free the wheel load, and turned. The driving ratchet has teeth 50, Figs. I and 2, engaged by a pawl 76 on m lever 70 which is manually oscillated, through an angle limited by engagement of a fixed abutment 100 with a boss 102, to drive the hoist. The pawl 76 is carried by a plunger 72 biased by a spring 74 and held against rotation by engagement of a suitably shaped boss 84 with a socket 82 in the lever 70 and may be reversed after the plunger 72 has heen withdrawn sufficiently to disengage the boss 84 from the socket 82: osocillation of the level 70 with the pawl 76 reversed turns the driving ratchet 46, 48 againt the friction of the disc 44 to provide the usual controlled lowering movement. The pawls 76 and 88 are both locked out of engagement with their ratchet wheels to permit slack in the load chain to be taken up rapidly. The hoist illustrated also incorporates the improvements of Specifications 683,943, 684,004, and 684,005.

The ribs stop short of the meeting edges of the bottom and sides of the vat thereby leaving spaces to facilitate cleaning. The ribs 13 may be open at their ends to provide a free circulation of water therethrough, or they may be closed. The abutments 11 may comprise wooden bars secured to the vat by screws and metal sockets 12 secured to the base may be provided to receive the bottoms of the abutments. Or the abutments may comprise ribs upset from two opposite sides of the vat, or hollow metal members secured to two opposite sides and to the base. Alternatively the abutments may stop short of the base to facilitate cleaning. In the case of a power-driven machine the transmission and reversing gear therefor may be housed beneath the vat.

A keyboard is associated with each display tube and provides operator facilities for various editorial functions such as tabulation and the insertion and/or deletion of single characters or of whole lines of characters the position at which on operation is to be effected being indicated by a displayed cursor. Certain portions of the display, however, are "protected", e.g. in displays of text having fixed format information, such protection being effected by special codes interspersed in the character information codes and which cause the display of (delta shaped) symbols bracketing the " protected " information, the special code signals also operating to prevent the cursor from being positioned at any "protected" character so that any operator control is prevented at such positions. Facilities are provided for printing the contents of the appropriate section of the store and for stopping the transmission of data if any message would exceed the capacity (or remaining capacity) of the screen (or of the appropriate section of the store) until intervention by the operator. The full display screen capacity is 25 lines each of 80 characters &c. the latter being produced by straight line deflections of the beam with a maximum of 12 possible strokes. Details of the arrangement and operation are described with reference to block circuit and other diagrams (not shown).
