Patent GB-469421-A (GB)
Title: Improvements in or relating to the manufacture of fluorohydrocarbons
IPC: C07C17/08
Filed: 1936-01-24
Abstract: Hydrogen fluoride is reacted with acetylene in the presence of mercuric compounds and/or active carbon.  Mercuric oxide, chloride or fluoride may be supported on carriers, for example activated charcoal.  The hydrogen fluoride may be anhydrous or in the form of an aqueous solution.  The reaction products are mainly vinyl fluoride or difluorethanes, chiefly ethylidene fluoride, and can be separated by fractional distillation.  A mixture of gaseous hydrogen fluoride and acetylene may be passed over the catalyst, such as the product obtained by mixing granulated activated charcoal with a suspension of mercuric oxide and drying, in an iron vessel.  The reaction heat raises the temperature, for example to 20--40 DEG  C., which can be regulated by varying the quantity and composition of the circulating gases, or by adding indifferent gases.  Elevated temperatures can, however, be used to start the reaction.  Part of the gases leaving the catalyst may be removed and the fluorohydrocarbons separated, or the latter may be removed directly with suitable solvents.  The products are suitable as refrigerants and for the manufacture of polymerization products.

Sheets, travelling.-A modified construction of the leaf feeding mechanism described in the parent Specifications comprises a thin, soft, preferably flexible metal strap 8, e.g. a plate spring, the lower end of which is adapted to be received between the pulley 7 and its belt (not shown). To the top of the strap 8 is attached a V-shaped flexible arm 13 and a sleeve 12 slidable along a guide bar 11. The free end of the arm 13 is rubber tipped, e.g. by tube 14 held in place by notches in the edge of the arm, and in shape is preferably slightly concave towards the leaves 3 so that in its upward motion the concavity will tend to increase and the tip 14 will bear with its upper edge on the front leaf. A stop 15 on the bar 11 limits the upward movement of the arm 13 due to momentum after the strap 8 has left the pulley 7. The arm 13 is lowered by reversing the motion of the belt.

Title: Improvements in or relating to stationary track devices for detecting hot-running railway axle-bearings or brakes
IPC: B61L1/20
Filed: 1960-01-22
Abstract: 911,865. Hot axle-box radiation detectors. SIEMENS & HALSKE A.G. Jan. 22, 1960 [Jan. 26, 1959], No. 2513/60. Class 40 (3). A device for detecting hot-running railway axle bearings or brakes is placed by the track and comprises a detector mounted in a totally enclosed housing. Radiation from the hot members is focused on to the detector, and the housing has air circulated about it. The temperature of the circulating air may be controlled to compensate for the speed of a passing train or for the effect of the air through which the train has passed prior to testing. The detector 6 receives the radiation via an optical system, e.g. the mirrors 3, 2, 5, 4. The radiation passes into the housing 9 through a window 11 and, when opened, through shutters 7, 8. Shutter 7 is opened only for the passage of each hot member, but shutter 8 is opened for the passage of the complete train. The shutter 7 and the interior of housing 9 are blackened, while the outer surface of shutter 8 is reflecting. Housing 9 is carried in a chamber 12 through which air is circulated and which is preferably doublewalled. The air is drawn in by a fan 16 via a pipe which has its inlet 18 at the same height as the train members to be tested. For compensating for the effects of solar radiation, or of wind or speed, on the temperature of the hot member in a certain distance travelled before the testing operation, and also for compensating for the ambient temperature of the measuring equipment, the air drawn into the chamber 12 is heated or cooled by a device 19.

Title: Improvements in or relating to educational appliances for teaching chemistry
IPC: G09B23/26
Filed: 1947-01-28
Abstract: 639,654. Educational appliances. HARDIE, D. E., and SUTHERLAND, G. O. Jan. 28, 1947, No. 2691. [Class 146 (ii)]  For illustrating chemical characteristics and reactions of the chemical elements, shaped objects represent the elements and have a form built up of unit components representing electrons arranged to indicate atomic number and valency. The unit component comprises a right angled triangle and in a representation each hypotenuse exposed represents a valency electron. In a modification, instead of the number of triangles equalling the atomic number, for electro-positive elements the object comprises a number of triangles corresponding to the valency with the hypotenuse of each triangle exposed and for electro-negative elements the object comprises a number of triangles equal in number to eight less the number of valency electrons which the element can accept, the objects having a statement of the atomic mumber of the element. The objects may be coloured to indicate certain physical properties, preferably electro-positive elements being coloured alike and electro-negative elements alike but of a different colour. Of the objects shown on the drawings, 1 (coloured red) represents a hydrogen atom, atomic number one, univalent ; 3 (grey) represents helium, atomic number 2, inert with no hypotenuse exposed ; 4 (green, electro-positive colour) represents lithium, atomic number three, univalent ; 5 (yellow, electro-negative colour) represents sulphur, atomic number sixteen and valency six for this representation. In the modified form of objects shown, 11 (yellow-green) represents chlorine, atomic number 17 and is marked 18-1, umvalerit ; 12 and 13 are alternative shapes of objects for bi-valent electro-negative elements such as oxygen (light blue), atomic number eight marked 10-2 or sulphur (yellow) marked 18-2 ; 14 (lilac) represents tervalent nitrogen atomic number seven and is marked 10-3. A chart is also described showing the different modified forms that a number of common elements may assume for different valencies, the elements being arranged in a circle in increasingly electro-negative order. Fingers are provided to be moved over the sectors and are used to determine the forms to be employed in setting out a simple reaction between two elements. The objects may be cut-outs or adhesive stamps and can be built up jig-saw fashion to give chemical compounds or combinations of atoms.  The Provisional Specification describes also the use of transfers instead of shaped objects.

Abstract: 329,974. Accles, J. G. Jan. 26, 1929. Breech actions, movablebarrel.-Relates to pistols for slaughtering and other purposes of the kind in which the barrel a drops down or swivels about a pivot c, and means are provided for locking the barrel in the closed position when the trigger is pulled. According to the invention, the barrel is locked by a member pivoted on the frame of the pistol. The locking member may be a sear, or an arm operated by the trigger, or the trigger itself. As shown, the trigger d, which is pivoted on the frame at h, has a projection e which fits into a notch f in the barrel a when the trigger is pulled, thereby preventing any opening of the barrel so long as the trigger is pulled. The invention may be applied to the pistols described in Specifications 206,090 and 322,439.

Filed: 1923-01-30
Abstract: 214,016. Jennings, E. Jan. 30, 1923. Saddles for cycles are provided with a spring- roller cover mounted and arranged in the following manner. The roller c is housed in a tubular casing a having one end fitted with a screwed cap a<1> and the other end integrally formed with a closing portion. The spindles d, d<1> of the roller are rotatable in plates e, e<1> within the casing, the plate e<1> being prevented from turning by the engagement of slots f<1> therein with radially projecting tongues f within the casing. A flat spiral spring g is fixed at one end to the spindle d', its other end being twisted or bent over for attachment to the plate e<1>. A washer e<2> rotating with the spindle d<1> serves to keep the spring in position. The slot of the casing has its upper edge bent slightly upwards to form a lip to keep out water. The casing is secured to the baseframe m of the saddle by a band b fitted with a bolt b<1> and tightening-nut b<2>, and to retain the cover h in its operative position a loop at the free end of the cover is engaged with a hook k upon a screwed-rod k<2> and a split spring-ring attachment j to the front spring or springs of the saddle. The inner end j<1> of the ring is screwthreaded to form a nut, so that when the rod k<2> is screwed up till its end engages with the hole k<3> of the ring, further screwing up of the rod causes the ring to become distorted and to grip the saddle spring. The cover has side flaps stretched thereto and the loop is made of material thicker than the width of the slot in the casing.
