Title: Tobacco substitute and products comprising the same
Inventor: KIRKLAND VANCE
IPC: A24B15/16
Filed: 1963-10-01
Abstract: A tobacco substitute for smoking comprises a combustible material together with minor proportions of flavouring and other modifying agents, the combustible material being cellulosic in nature and intermittently associated with one or more combustion-modifying inorganic compounds, including a hydrated metal compound to reduce the burning rate of the combustible material.  The combustible material may comprise lightly beaten wood pulp of high alpha cellulose content or an oxidized cellulose product comprising an anhydroglucoronic acid polymer.  The tobacco substitute may contain an alkali metal-, alkaline earth metal-, or ammonium carbonate, bicarbonate, sulphate, chloride or nitrate.  The hydrated metal compound is preferably a hydrated magnesium sulphate.  The tobacco substitute is produced by impregnating the cellulosic material with a mixture of water and the combustion modifying compound or compounds and drying the product.  The combustion modifying compounds are incorporated by slurrying them with the lightly beaten pulp, forming the pulp into paper and subsequently impregnating the paper with flavouring agent and shredding.  Humectants and colouring agents may be added.  Quantitative examples are given.  The tobacco substitute may be used with filter containing an agent, e.g. alkali metal carbonates or bicarbonates, capable of neutralizing acid in the smoke.

Title: Catalytic converter
IPC: F02B61/04
Filed: 1972-08-21
Abstract: 1395960 Purifying exhaust gases FORD MOTOR CO Ltd 21 Aug 1972 [13 Sept 1971] 38866/72 Heading F1B Exhaust gas purifying device comprises a housing 10 having an inlet 12 and an outlet 14, a catalyst 22 and a heat storing means 26 comprising a material 34 that absorbs sufficient heat to change its physical state at a temperature exceeding the activation temperature of the catalyst and reverses said physical change of state to transfer conductively the released latent heat to the catalyst when the catalyst temperature declines below the temperature at which the material changes its physical state. Housing 10 has double walls filled with thermal insulation 16. A flap-valve 21 prevents reverse flow. The catalyst support 22 consists of small passages 24 containing finely-divided catalyst. The heat storing means consists of a container 28 inserted into an opening in the rear end of the support and extending almost to the front of the support. A tapered extension 30 of the container projects rearwardly from the support and is exposed to the hot gas stream which leaves the passages 24. Heat transfer is enhanced by fins 33. The container is filled with zinc 34. During operation of the catalyst, the body of the container is heat by conduction and the extension 30 by convection so that the zinc melts. When the engine is stopped, heat from the container maintains the temperature of the catalyst so that it rapidly returns to operating temperature if the engine is re-started after a short period. In a first modification Fig. 2,  (not shown) the single central container is replaced by several smaller containers spaced around a circle centred on the support axis. In a second modification, Fig. 3 (not shown) two containers, each frusto-conical in shape are positioned, one upstream and one downstream of the catalyst support, in the tapered ends of the housing. Fig. 4 shows a device having a tangential gas entry and a heat reflector 40 backed by thermal insulation 44. The casing 42 is corrugated to reduce convective heat losses from the interior of the housing. The casing 42 may be made small enough to enter the inlet 36 and be mounted on a reciprocable rod which also carries a plate which closes the inlet 36 when the casing 42 is moved into the inlet at the time the engine is stopped. The material 34 may also be aluminium or tin, or alloys thereof, mercury, bismuth or cadnium.

Abstract: 1,246,352. Collapsible steering columns. MONROE AUTO EQUIPMENT CO. 12 Aug., 1969 [21 Aug., 1968], No. 40362/69. Heading B7H. A collapsible steering column capable of being returned to its initial normal position after having been collapsed due to impact comprises forward and rearward shaft sections 20, 22 non-rotatably but slidably interconnected. The rearward section 22 is mainly hexagonal in cross-section and slides within an annular guide member 66 having an internal complementary configuration to permit the rotary motion of section 22 to be transmitted to the forward section which comprises a tubular wall member 64 fixedly secured to the member 66 and likewise at its opposite end to a mounting portion 52 which is coupled to the usual steering gear box. The tubular wall member 64 provides forward and rearward chambers 48, 50 divided by a valve member 80 coupled to the end of the shaft section 22. Fluid is contained in the respective chambers and upon impact at the end of the steering column the section 22 is forced forwardly causing spring loaded discs 100, 102 to be pushed back and open ports 94 ... 98 permitting fluid to flow from chamber 48 into chamber 50. At least one opening 114 is provided communicating with one of the ports and is normally closed by a sleeve 118 which remains in this position during the forward movement of the section 22, Fig. 4. However upon the section 22 being withdrawn the sleeve 118 is caused, due to the fluid in the rearward chamber 50, to slide and uncover the opening 114 such that a reverse flow of the fluid from chamber 50 to chamber 48 can take place thereby permitting the steering column to be reset to its initial position. By adjusting the nut 90 securing the valve member 80 and discs 100, 102 against the spring 110 on the end of the shaft section 22, the load at which the column collapses under impact may be preset.

Title: Magnetic field sensing device
IPC: G01R33/02
Filed: 1959-12-03
Abstract: 936,615. Magnetic tests. MAICO ELECTRONICS Inc. Dec. 3, 1959 [Dec. 16, 1958], No. 41155/59. Class 37. A magnetic field-sensing device comprises a sensing lead having a low reluctance core forming a closed loop 18, Fig. 4, with a pair of coils 20 and 21 wound on opposite sides thereof. These coils are wound in identical manners having input ends 21a, 20a connected to a common terminal 17 and output ends 21b, 20b to a pair of terminal mounting sprigots 22 in moulding 15 or 16; depending on the sense of the field to be detected. The mounting 11 includes a quantity of semi-flexible, resilient material enclosing the core and coils for mechanical and heat protection. An oscillator 32, Fig. 6, sends pulses through the coils which have oppositely arranged diodes 33 and 34 connected to their output ends thus permitting one coil to carry positive and the other negative pulses only. Across the diodes is connected a potentiometer 35 with the centre tap 36 so arranged as to equalize the pulses in the absence of a magnetic field. The pulses pass through a filter network 37, thence to a load resistor 40 connected through a further diode 41 to a predetermined voltage responsive device 45. When a magnetic tab 28, Figs. 2 and 3, moves past the sensing device, the magnetic flux threading the coils changes, resulting in an increase in the current from one coil and a decrease in that from the other, hence the output pulses are not equal resulting in a change in the voltage across the load resistor 40. Because of the diode 41, the voltage applied to the detector 45 can charge in one direction only thus making the device sensitive to the polarity of the field of the tab 28.
