Patent GB-131598-A (GB)
IPC: E04B1/70
Abstract: 131,598. Schmidt, [nÚe Ubben], G. Oct. 7, 1916, [Convention date]. Air-heating stoves.-Stoves for drying buildings and the like are formed in separate units adapted to be coupled by a connecting member which forms an air shaft at the point of connexion. The figures show two stove units, each composed of lower and upper frames c, d, connected by upright angle-irons b which enclose the fuel space above the bottom grate a. The units are connected by plates i, with inturned edges which engage two of the channel irons, and secured by bolts i'. An air-shaft h is thus formed, to which air is supplied from openings s in the lower frame or in the bottom of the plates i, and from which it may be led through a conduit to the part to be dried. The connecting-member may also be formed as a sheet-metal box, open on the two sides facing the ends of the stove units. Doors g are provided in the cover f for the supply of fuel.

Abstract: 941,291. Organosilicon compounds. UNION CARBIDE CORPORATION. April 6, 1962 [April 7, 1961], No. 13448/62. Headings C3S and C3T. In the transisterification of an organosilicon compound containing at least one Si-bonded alkoxy radical with a hydroxyl-containing organic compound, the reaction is effected in the presence of an organic acid and a basic compound comprising an alkali metal hydroxide having an atomic number greater than 11, ammonium hydroxide, a quarternary alkyl ammonium hydroxide, a nitrogen-containing organic base, or an organic acid salt thereof, the organic acid being present in amount in excess of that stoichiometrically required for complete reaction with the base. Numerous examples are given of the organic acids, basic compounds and the reactants of which the hydroxy compound may be mono- or polyhydric including polyoxyalkylene compounds, and the organosilicon reactant may be a siloxane or silcarbane-siloxane containing Si-bonded hydrocarbon (saturated or unsaturated) and alkoxy radicals, or a silane of the formula wherein R<SP>11</SP> is a monovalent hydrocarbon radical, X is an alkoxy radical, R<SP>1</SP> is an alkyl radical, R<SP>11</SP> is an alkylene or arylene radical, a is 1, 2 or 3, c is 0, 1 or 2 and d is 0, 1, 2 or 3. The reaction can be effected at room temperature but is preferably conducted at a temperature above the boiling point of the alkanol produced, e.g. at 100-200C. If desired a solvent such as toluene or xylene may be used. Upon completion of the reaction, the acid is removed or neutralised. The reaction products may have formulae corresponding to those of the starting organosilicon compounds or may be silanes of the formula R<SP>11</SP>aSi(O-Z-O)  4 - a -Si R<SP>11</SP>a, where Z is a divalent hydrocarbon radical, or co-polymers of R<SP>11</SP>aSi O 4-a/2  and -R<SP>11</SP>2Si-O-Z-O-Si R<SP>11</SP>2- units. Examples describe the above reaction to produce block copolymers of siloxane and polyoxyalkylene units.

Abstract: 1352090 Solid state oscillators; frequency modulation HEWLETT-PACKARD CO 22 March 1972 [29 March 1971] 13470/72 Headings H3T and H3R A tunable microwave oscillator comprises a solid state negative resistance device 11, a YIG sphere 13 positioned for operation in a magnetic field and having a ferrimagnetic resonance characteristic for tuning the solid state device over a desired frequency band by variation of the intensity of the magnetic field and a coupling circuit 12 connected in series with the solid state device and the output 18 of the oscillator to provide interaction between the solid state device and the YIG sphere. The solid state device 11 may be a bulk effect device such as a Gunn diode or may be an Impatt diode. The coupling circuit 12 may be a transmission line adjacent the sphere 13 or a coupling loop partially or completely encircling the sphere. D.C. bias potential from 14 is applied to the device 11 via a #/4 transmission line 15. An impedance transforming network 17 is connected between the YIG coupling circuit 12 and the output 18 so as to provide a loading characteristic to operate the oscillator in the desired YIG tuned mode and tend to inhibit oscillation in spurious modes. As shown in Fig. 2 a Gunn diode 11 is mounted on a heat sink 21, the YIG sphere is mounted on an insulating rod 26 and the coupling loop 12, the impedance transforming network 17 formed as a gold metalization film transmission line and the #/4 line 15 are mounted on quartz substrates 25, 28.

A frequency selective attenuator (33, 34, 35, Figs. 4 and 5, not shown) may be connected between the impedance transforming network 17 and an isolator or ferrite circulator (32) from which the output is taken. The attenuator may be formed as a microcircuit on the quartz substrate 25 and includes a series arm in the form of a #/2 transmission line (33) and shunt arms each formed of a resistor (34) in series with a shorted stub (35) #/4 long.
Patent GB-135249-A (GB)
IPC: C21D9/40
Abstract: 135,249. Oubridge, W. A. Nov. 6, 1918. Rings.-In order to remove internal stresses and ensure a piston-ring acting on the cylinder wall with uniform pressure, the ring, cut or uncut, is first heated in a furnace, then bent to the selected curve (an involute of a cycloid) tetween dies, and then removed from the dies and subjected to reheating and regulated cooling. The rings A' are heated in a furnace b provided with a slot c at the bottom for their passage, and are removed one by one into position over a shaped mandrel p having a conical top, by a reciprocating slide d actuated by a cam m through roller l and links j, i, e. The ring is fixed on to the mandrel by a platen q drawn down by rods r, provided with nuts r<1> upon which press springs r<2> acted upon by a crosspiece s provided with a rcller s' which engages a rotary cam v. The platen q is then returned 'by springs u, and the ring removed from the mandrel by a stripper x connected by rods x<1> to a crosspiece y provided with a wiper which engages a rotary cam w. In the case of unsplit rings, the ring may be notched before being heated, when the contraction on the mandrel p may be made to cause the ring to fracture at the nick, thus dispensing with a separate operation for splitting the ring. After being shaped, the ring is moved forward by the next ring into a receptacle o. The ring is finally reheated and may be cooled by passing on a conveyer through a series of cooling- chambers.

As shown, a roll is delivered into each pocket from the zig-zag hopper 40, a star-wheel, controlled by a counting circuit, co-operating with side guide bars 48a, 48b to position the rolls axially, and side guide bars 50a, 50b and outer guide bars 52 guiding the rolls around the descending arc 10c of the conveyer 10 so that the rolls are successively delivered on to a plate 54 and then into the accumulating unit 20. The latter comprises a base 30, divider plates 34 and end plates 32a, 32b to form a number of compartments the height of each of which is substantially equal to the sum of the diameters of a pre-selected number of rolls so that, when one compartment is filled, the succeeding rolls roll over the uppermost roll in the filled, and drop into the next, compartment. The horizontally-reciprocable pusher 58, has blades 64 which are of the same height and width as a compartment and which are positioned just inside the compartments to form compartment inner side walls while the unit 20 is being filled with rolls. The upper edges of the plates 32a, 32b, 34 of the unit 34 all lie in the same plane slightly below the level of the plate 54. A carton B supported, between the end plates 32a, 32b, on an extension 30a of the base 30, is adapted to receive a load of rolls from the unit 34 when all of the compartments of the latter are completely filled whereupon the conveyer 10 is stopped and the pusher 58 is actuated to push the rolls from the compartments into the carton B. The accumulator unit 20 and the pusher 58 are demountable to allow for the substitution of similar units and pushers for handling rolls of different sizes.
