IPC: E04H12/32
Filed: 1916-05-18
Abstract: 100,497. Brandes, L. May 18, 1916. Supporting. - In apparatus for supporting a lamp from a telegraph or other post, wall, or other support by means of an arm, which can be swung in a plane more or less parallel to the direction of the roadway tc allow of access to the lamp, the axis of the arm is inclined tc the horizontal, or ball-andsocket joints, universal joints, &c together with suitable guides are used to obtain the same or approximately the same movements. Fig. 5 shows one form in which the axis a of the arm is inclined to the horizontal and also at an angle to a vertical plane at right angles to the direction of the road. The arm is lowered by gravity and raised by a rope c and a winding-device d. In this form, the lamp o is at a shorter horizontal distance from the supporting-post in the lower position than in the working position and, as shown in dotted lines, the path of the lamp recedes more quickly from the roadway when descending in one direction that when descending in the opposite direction. In a modification, the lamp is held in the working position, which is slightly beyond the highest position, by a stop bearing against the post and is raised and lowered by a rope. The Specification as open to inspection under Sect. 91 (3) (a) comprises also one form in which the axis of the arm is horizontal. This subjectmatter does not appear in the Specification as accepted.

Patent GB-630715-A (GB)
Title: Production of nitric oxide
IPC: C01B21/30
Filed: 1947-03-20
Abstract: <PICT:0630715/III/1> Nitric oxide is produced by passing a nitrogen oxygen gas mixture through a central high temperature reaction zone and two zones which alternately serve as preheating and cooling zones respectively, the flow of gases being periodically reversed. Fluid fuel is supplied to the reaction zone by means of pipes extending through or nearly through one or both of the outer zones, the fuel feed being regulated so that fuel passes only through that zone which at the time is functioning as a preheater. The reaction zone is a bed of large refractory objects (e.g. up to 5 inches) and the outlying zones contain smaller refractory material; all the beds may be progressively graded to merge into one another.  In the illustrated embodiment the beds F1, F2, F3 are supported on a water-cooled grate 21 in a vertical refractory cylindrical shell 10, the ends of which are closed by domed covers 14, 141, enclosing gas spaces above and below the bed.  Conduits 18, 181 and a reversing valve R provide for the supply of the gases and the withdrawal of the product.  The fuel supply pipes 25, 251 are water jacketed and may be enclosed in ceramic sheaths 26, 261.  In a modification, pipes 251 are omitted and fuel is supplied only during the upstroke half of the cycle.  The products of the downstroke half are thus free of fuel combustion products and may be separately recovered.  Specification 598,534 is referred to.

Filed: 1970-02-18
Abstract: 1283687 Automatic frequency control; transistor amplifiers SIEMENS AG 18 Feb 1970 [19 Feb 1969] 7702/70 Headings H3A and H3T In a retroactive A.F.C. system wherein an oscillator has its frequency controlled by a variable capacity diode, and wherein coarse frequency control is effected by applying a bias voltage to the diode, variations in loop gain arising from varying the bias are obviated by also applying the bias to a gain control circuit in the loop. As described, Fig. 3, the gain control circuit comprises an amplifier T 1  ... T 4  with a negative feedback loop GK which includes an FET, T 5  acting as a variable impedance in a potential divider. The impedance, and thus the amplifier gain, is adjusted by the control signal which adjusts the bias on the oscillator tuning variable capacity diode Var. Initial lock-in of the circuit is provided by sweep generator T 6 , T 7 . The control arrangement may be employed in a frequency modulated transmitter, Fig. 2, in which the output from oscillator O s  is mixed at M with a signal from a refrence oscillator R o  to produce an I.F. signal. This I.F. signal and the required information signal Zf2 modulated on to a similar carrier are applied to a phase comparator to produce an error signal U R  which is amplified by the gain controlled amplifier GV to produce the frequency control signal for the oscillator O s .

Abstract: 1426355 Closing casings for food (especially sausages) NATURIN-WERK BECKER & CO 16 Feb 1973 [16 Feb 1972 28 Sept 1972] 7740/73 Heading A2B A shirred food (e.g. sausage) casing is closed by compressing the end portion and sealing the compressed end portion with adhesive. The end portion may be gripped with pincers 3, compressed, and adhesive 4 applied through a metal pipe 2. The closure so formed comprises two to three folds of the casing, and may be pushed inside the casing. The adhesive may be applied at discrete positions only. Alternatively the casing may be gripped in two separate places by fixed slides 5 and movable slides 6 to define a portion 9 into which adhesive is introduced through a pipe 8, or by injection through a cannula. The portion 9 is then compressed by moving the plunger 7 and the slides 6 towards the slides 5, so that adhesive is distributed over its inner surface. The adhesive may be gelatine, starch, gum arabic, casein or collagen, and may be water soluble and capable of swelling. The casing may be made from edible material e.g. collagen, alginate, cellulosic material, or synthetic thermoplastics. The gripping means and adhesive supply means can be arranged for synchronous movement towards and away from the casing.

Title: Process and apparatus for stretching and widening elastic bodies and fitting them to other bodies
IPC: B23P11/02
Filed: 1922-03-16
Abstract: 177,167. Maggiora, D. March 17, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Elastic-grip joints.-Consists in means for pneumatically expanding an elastic tube in order to pass it onto, or enclose in it, a body whose outer diameter is greater than the unexpanded internal diameter of the tube. As shown in Fig. 1, the elastic tube i is fitted at one end to a nozzle h, and is enclosed in a rigid perforated sleeve r, by which the degree of expansion cf the tube is limited. A hollow piston-rod c having a detachable conical end plug g is forced by compressed air through the tube i. Ports a<2> in the cylinder cover a<1> enable some air to escape around the piston-rod to the back of the plug g, to facilitate the passage of the piston-rod through the tube. When the piston-rod protrudes at the free end of the tube i, the plug g is removed, and the body s, Fig. 2, to be sheathed, is inserted in the end of the rod. By means of a cock f<1> and a port b<1> in the piston b, the interior of the piston-rod is next connected to a suction pipe f and the body s is drawn into the rod. The piston-rod is then with. drawn from the tube, leaving the body s within it. Alternatively, the body s is drawn into the piston-rod by a wire or the like passing therethrough. In another form, the tube passes through a vacuum chamber and is expanded by the atmospheric pressure in its interior. Means for connecting the tube i to the nozzle h are also described. If the body s is of an elastic nature, it may be stretched during insertion by a cord s<1> attached to its outer end.

Title: Filaments and films of polymers of 3-methylbutene-1
IPC: D01F6/04
Filed: 1962-02-28
Abstract: Filaments and films are made from a polymer of 3-methyl-butene-1 by extruding the heat-softened or molten polymer through a shaping orifice and taking up the product at a linear rate of more than 400 metres per min. preferably 800 m./min. or more.  In addition to homopolymers, copolymers or a subsequently polymerized monomeric mixture containing a major amount of 3-methyl-butene-1 and a minor amount of an ethylenically unsaturated comonomer, e.g. another branched olefine or an unbranched olefine, e.g. ethylene, propylene or butene-1, may be used.  Poly-3-methyl-butene-1, may be extruded at 285-375 DEG  C. Before extrusion the polymer may be subjected to extraction with a hot hydrocarbon solvent to remove material soluble therein. Specified solvents include heptane and other alkanes, e.g. pentane and hexane, ethers, e.g. diethyl ether, ketones, e.g. acetone and methyl ethyl ketone, and chlorinated hydrocarbons, e.g. methylene chloride and ethylene dichloride.  A phenolic thermal stabilizer may be incorporated into the polymer, e.g. alkylene bisphenols in which the alkylene groups contain up to 4 carbon atoms and each phenolic ring is substituted with up to 4 alkyl groups, each of which contains up to 6 carbon atoms, an example being 2,21-methylene bis - (4 - tertiary butyl - 6 - methyl phenol), or a monocyclic alkyl phenol containing up to 4 alkyl groups on the ring each of which contains up to 6 carbon atoms, an example being ditertiary butyl methyl phenol. The stabilizer may be used in a proportion of 0.01-5.0% based on the weight of the polymer.

Filed: 1929-03-09
Abstract: 330,598. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). March 9, 1929. Mothproofing.-In tha treatment of materials such as wool, fur, &c., with solutions of substances in organic solvents, as for example in mothproofing such materials, the solvent used consists of a mixture of the customary volatile solvent with a second solvent which is more difficultly volatile. The second solvent may be, for instance, a higher alcohol such as butyl or benzyl alcohol, cyclohexanol, cyclohexanone, or esters such as phthalic acid methyl ester, and a small quantity such as 1 to 2 per cent. is usually used. The addition of the less volatile solvent prevents the appearance of a grey or white deposit on the material after evaporation of the solvent.

Title: Improvements in or relating to a method of making valve tappets
IPC: B22C9/00
Filed: 1939-03-10
Abstract: 526,203. Making tappets ; moulding processes. EATON MANUFACTURING CO. March 10, 1939, No. 7793. Convention date, June 18, 1938. [Classes 83 (i) and 83 (ii)] [Also in Group XXIV] A sand mould for casting a valve tappet or other hollow body having spaced transverse walls 32, 34, Fig. 2, and a windowed body 36 between them, has a parting surface in the plane of each of the mould cavities for said transverse walls. The mould may comprise a middle section 58, Fig. 6, with cavities 74, 76 for the walls 34, 32 and a segmental cavity 112 for the body 36, an upper section 104 with an annular cavity 108, which may be segmented, for body part 30 and cavities 188 for the runner &c. and a chill plate 80 of iron or copper. The cavities 112 and 108 both taper upwardly to facilitate withdrawal of the patterns as shown at 42, Fig. 4. The pattern 64 is apertured to receive the legs of the pattern 42 when moulding. In another modification two substantially similar middle sections 148, 160, Fig. 16, one inverted on the other so that two shallow depressions 74<SP>1</SP> together produce the cavity for a central transverse wall. These sections also have cavities for two end walls and windowed bodies connecting them to the central wall, the windows in the two halves preferably being out of line. The mould is completed by a chill plate 180 and a sand mould section 184 containing the runner 188 &c. Each mould is preferably made to cast a number of tappets at one time and to form the windows with a bevelled edge 38. The cast blanks are machined cylindrical and finished to desired form, one or more of the transverse walls being drilled or drilled and tapped if desired as shown at 132, 134 in Figs. 11 and 13.

Title: Control system for electrical heating units

Filed: 1950-03-29
Abstract: 675,543. Electrically-tripped switches; switches held set and freed mechanically. PROCTOR ELECTRIC CO. March 29, 1950. [April .14, 1949] No. 7826/50. Class 38 (v). [Also in Group XXXV] In a control system for oven heating units as described in Specification 675,539, in which a single-knob controller provides for flash heating of certain units, disconnection of subsidiary units during flashing to avoid overload of the supply, and automatic change-over to normal heating connections after a predetermined amount of flashing, together with restoration of supply to the disconnected units, the arrangement is now such that the the changeover switch for establishing flash or normal heating connections is latched in the flash position when the control knob is at its "off" position, so that a small movement of the knob from this position immediately initiates flashing. In the arrangement of Fig. 2a, which shows the disposition of the various switches and cams of the controller when the knob 40 is in its "off" position, switch arms 9, 10 are maintained in the flash position shown by toggle links 32, 36 moved over a dead-centre position by a cam 38 when the knob was turned to "off". A small clockwise movement of the knob will now cause cams 17, 25 to close contact pairs 8, 11 and 28, 29, thereby connecting the heating units 2a, 2b in parallel across the supply for flash heating. The separation of contacts 8, 12 prevent energization of a subsidiary unit 6. Cam 38 is clear of the toggle links, but a lug 32a retains them in the position shown. A cam 30 displaces the free end 24a of a bimetal carrier 24 (pivoted at 27) for contact 28 towards the junction of the toggle links by an amount dependent on the degree of rotation of the control knob. The bimetal carrier is heated by a resistor 21 in series with unit 2b and eventually the carrier distorts sufficiently for its free end to move the toggle links over their dead-centre, whereupon contacts 9, 10 change over under their own resilience and connect the units 2a, 2b in series for normal operation as well as restoring supply to subsidiary unit 6. Normal operation continues under control of thermostat 21, 24, 28, 29 as set by cam 30. If initial flashing is not required, the control knob is moved in the reverse direction so that the end 24a of the bimetal carrier 24 disables the toggle connection (under the action of clams 30, 25) when cam 38 moves clear of the toggle. In other arrangements a bimetal latch similar to that described in Specification 675,539 replaces the toggle mechanism for holding contacts 9, 10 in the flash position.
