Patent GB-655869-A (GB)
Title: A method and a plant for the production of mixtures of hydrogen and carbon monoxide
Inventor: BOUDINEAU LOUIS
IPC: C01B3/38
Filed: 1948-12-04
Abstract: In the conversion of gaseous hydrocarbons or gases containing same, particularly methane, into hydrogen and carbon monoxide by controlled combustion with oxygen or with air which may be enriched with oxygen, controlled flameless combustion is arranged to take place in contact with a conversion catalyst, preferably a nickel-base catalyst, in the form of particles having a diameter p  not exceeding 1 cm., substantially to prevent carbon black formation by combustion with flame in the interstices between adjacent particles.  Intimately <PICT:0655869/III/1> premixed gases, which may or may not be preheated, with or without say at least 10 per cent steam are passed through channelled insulating block 4 and porous refractory diffuser plate 3 into refractory lined oven 1.  The gases are ignited at the surface of plate 3 and pass upwards through catalyst charge 5, consisting of nickel deposted on a refractory carrier containing silicon and aluminium, e.g. kaolin, so that the temperature of the gases at the oven outlet is at least 850 DEG  C.  The effluent gases pass to post combustion chamber 8, with air injected at 7 to effect partial combustion to increase the temperature, and are contacted with charge 9 of the same catalyst as in oven 1.

Title: Intermittent drive roller conveyors
IPC: B65G47/26
Filed: 1971-07-05
Abstract: 1310008 Roller conveyers ALVEY Inc 5 July 1971 [6 July 1970] 31481/71 Heading B8A An accumulation conveyer has groups of rollers 10 of which two rollers in each group are normally driven by a friction belt 20. An idler pulley 16, due to the belt, normally tends to align its axis with that of a driven pulley 13 but when a link assembly 33-34 is moved to the left by the depression of a sensor roller 10A under the weight of a stopped article A, the idler pulley 16 upstream of the pulley 16 immediately below the article A is pivoted about a vertical axis and causes de-clutching of the belt 20 with its associated rollers 10. The article following the stopped article is thus halted and spacing is maintained. Drive to rollers 10 not engaged by the belts 20 is provided by rollers 35 on the side of the conveyer remote from the belts 20. An endless belt 15 drives the pulley 13 but a chain may be used in place of the belt.

Title: Wedge immersed thermistor bolometers
IPC: G01J5/02
Filed: 1962-08-16
Abstract: 961,906. Infra-red detectors. BARNES ENGINEERING CO. Aug. 16,1962 [Aug. 29, 1961], No. 31542/62. Heading G1A. [Also in Division H1] A bolometer comprises a wedge shaped lens 1 (Figs. 1, 2 and 3) the aspect ratio of the part spherical front surface 2 of which differs from unity and the tapered surface 3 of which is provided with at least one "immersed" radiation detector 4 preferably consisting of a thermistor "flake" insulated from surface 3 by a layer 9 of arsenic modified selenium. The lens which is preferably made from germanium, is supported in a holder comprising two wedges 6 (also preferably of germanium) spaced by plastic buttons or strips 7 the whole being cemented together with an epoxy cement 8. The leads 5 are connected to the thermistor "flake" through an area of thin deposited gold which also defines the active area. The use of a wedge shaped lens is stated to improve the sensitivity, due to the reduction in "flake" size, by a factor approximately equal to the square root of the aspect ratio of surface 2 (5: 1 in the described embodiment). The bolometer is of particular advantage in instruments in which the product of the aspect ratios of field-stop and entrance pupil departs significantly from unity. A series of such bolometers may be used in an infra-red spectrometer each lens receiving only a narrow band of radiation of a particular wavelength and to prevent "cross-talk" baffles may be employed between each lens. Specifications 881,575 and 945,566 are referred to.

Abstract: 604,245. Glass manufacture. NAAM-, LOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 24, 1945, No. 31760. Convention date, July 20, 1940. [Class 56] [Also in Group XXXVI] An electric insulator consists of a glass body having gas dispersed in it, the volume of all gas bubbles together being 5-50 per cent of the total volume and the average size of the gas bubbles being less than 200 microns. The insulator may be made by heating finelypowdered glass in the presence of the gas to a temperature at which the glass particles coalesce, but not to a temperature at which the bubbles would rise to the surface or join into large bubbles. The powdered glass may be heated in a mould under slight pressure, or the powder may be moulded first and then heated to the required temperature.

Title: Improvements in or relating to clocks combined with advertising devices
IPC: G09F23/16
Filed: 1932-11-10
Abstract: 403,515. Changing signs. ROGERS, E. A., 145, Church Road, Redfield, Bristol. Nov. 10, 1932, No. 31794. [Classes 3 (i) and 139.] Mechanism for intermittently driving rotary display prisms combined with a clock comprises a spring 17, Fig. 5, which is tensioned by a constantly rotating power shaft 15. The connection between the shaft 15 and the independent co-axial spring spindle 10 consists of a spring-pressed pawl on a disc 14 attached to the shaft 15 engaging a notch in a disc 21 fixed on the spindle 10 and carrying the spring engaging pin 20. An adjustable trip releases the pawl after part of a revolution and allows the spring 17 and spindle 10 to return sharply till arrested by a stop. This motion is communicated through bevels y, x and a spindle v to a unidirectional clutch 27<1>, Fig. 4, which through gearing t, s rotates a crank-pin q and oscillates a pivoted arm j<1>, to which is geared at J, J<1> a similar pivoted arm j. The arms j, j<1> are duplicated top and bottom and carry at their outer ends the spindles i of the display prisms which are located on each side of the clock face. The prisms are thus given a motion away from the display windows and back again thereto, and have imparted to them by this motion a partial rotation by means comprising members 35 which abut against two co-axially but independently pivoted pawls 32, 33. The oscillation of the prisms is registered by a spring pawl 30. Each spindle i is shown as carrying two prisms, which may have two or any number of sides, and the advertisements are on removable plates. The shaft 10 may be driven by any means, such as the clock through gearing 16, and the clock may be electric or mechanical. A sound or light effect, e.g. a gong or an electric lamp, may give audible or visible warning of change of display. The display may be illuminated, and means may be provided for controlling the time of illumination.

A piece of meat 17 to be tenderized is placed on the support 16 which has projections 94 for engagement with a chain 15 by which it is transported from left to right through the apparatus. The chain is moved incrementally by a ratchet incorporated in a sprocket 66 in response to reciprocatory motion imparted to a link 73 by a cam follower 81, 75 coacting with a cam 79 driven by a motor 35. The motor also drives a pair of crank arms 50, one on each side of the apparatus, which are connected by rods 52, 53 with blocks 31 slidable on fixed guides 32 so that the two sets of cutting members (not shown), carried by members extending across the apparatus between blocks 31, are caused to reciprocate to penetrate the meat at angles determined by the inclination of the guides 32. Movement of the support 16 takes place whilst the blades are withdrawn from the meat. Associated with each set of blades is a stripper bar 56 which moves into engagement with the meat during penetration by the blades and is spring-urged against the meat during withdrawal of the blades.
