Abstract: 965,491. Spiked plates. AUTOMATED BUILDING COMPONENTS Inc. May 15, 1962 [Sept. 11, 1961], No. 18601/62. Heading F2H. A spiked plate for connecting timber members is formed by striking teeth from a plate so that they remain attached to the plate intermediate their ends, by bridging portions which are twisted so that one end 16 of a tooth extends perpendicularly from one side of the plate and the other end 18 extends perpendicularly from the other side. In Fig. 1, the teeth are V- shaped in cross-section and a second similar set of teeth 30, 32 have the V pointing in the opposite directions as indicated in Fig. 2 (not shown) which depicts a longer plate having the uncut plate sides three times the length of those shown with the teeth formation therefore repeated to give two longitudinal rows of each form of tooth with three teeth in each of the four rows. The tooth ends 18 and 32 are shorter, and are barbed since circular holes 26 are prepunched adjacent the bridging portions and are divided when the teeth are struck. Two rectangular holes 24 are also prepunched to be cut into as the tooth ends 16, 30 are formed. Fig. 5 shows a form with teeth 56, 58 which are narrower than the slots from which they are struck. These teeth are not V-shaped in crosssection and the ends 56 and 58 are identical.

Inventor: LATOUR MARIUS
IPC: B65D51/16
Filed: 1917-12-20
Abstract: 130,022. Latour, M. Dec. 20. 1916, [Convention, date]. Addition to 127,318. Telephonic relays.-A series of vacuum-tube electric amplifiers are connected in cascade with interposed iron-core transformers, as described in the parent Specification, and a tuned circuit is provided at each stage of the amplification with the object of reinforcing only currents of a specified frequency. Fig. 2 shows an arrangement for wireless reception. The received oscillations are impressed on the grid-filament circuit of the tube 1, the plate circuit of which is coupled by a transformer 7 to the grid-circuit of the tube 2, and so on, the last tube 4 having a capacity 11 shunted by a resistance in its grid-circuit and consequently acting as a detector, giving a low-frequency current through the transformer 12 and telephone 10. The plate circuit of each tube includes the common battery 6. The transformer cores are provided with air-gaps, and the secondary of each transformer is shunted by a capacity 15, 16, 17, thus giving resonance for the desired frequency. The receiving-aerial is not tuned to this frequency, so that oscillations set up therein by atmospherics are not reinforced by the amplifiers. An arrangement similar to that of the tubes 1, 2, 3, may be employed for low-frequency amplification, the circuits connected to the grids being tuned to the frequency or pitch of the desired note. The highfrequency and low-frequency amplification may be combined in a wireless receiving-apparatus. The transformer cores are formed of laminµ of the shape .shown in Fig. 1 and divided transversely so as to leave an air-gap E. The primary coil consists of layers X, Z connected in series, the secondary coil Y being interposed between the coils X, Z.

Abstract: 510,110. Catalysts for cracking oils. STANDARD OIL DEVELOPMENT CO. June 29, 1938, No. 19332. Convention date, Oct. 22, 1937. [Classes 1 (i) and 32] Catalysts, for the conversion of high-boiling hydrocarbons into lower boiling hydrocarbons suitable as motor fuels of high octane number, such as Fuller's earth, bentonites, zeolites &c., are prepared by mixing the finely divided catalytic material with a small amount of a finely divided 'solid polycyclic hydrocarbon, e.g., anthracene or naphthalene, moistening the mass with a small amount of water, moulding into small compact masses, e.g., pills, pellets, tablets &c., and then heating, prior to their use as catalysts, to a temperature sufficient to boil off the hydrocarbon without leaving any decomposition products on the catalyst. The catalyst and hydrocarbon may be mixed in the proportion of 1-20 parts hydrocarbon to 99-90 parts of clay, increased pressure in the moulding operation requiring a greater proportion of hydrocarbon. Preferably, the mixture is formed into 10-12 mm. pills which are reground to 10 mesh and reformed into 4 mm. pills. The conversion process is carried out at about 850‹F and the catalyst is regenerated by oxidation ; the catalyst prepared as above requires a shorter time for regeneration. Examples describe the conversion of a West Texas gas oil using catalysts prepared as above, showing the yield in successive cycles, and also the conversion and regeneration times. Comparison is made between such catalysts and compressed catalysts not made with such hydrocarbons.

Coke ovens.-Comprises a construction of coke oven of the kind in which regenerators extending be. neath and parallel to the ovens are divided into a number of compartments corresponding to groups of vertical flues in the heating-walls. The flues, regenerators and connecting-passages are divided into two symmetrical independent halves or units, each unit comprising parts on both sides of a wall extending along the axis of the battery and affording a path for the gases quite distinct from that of the other unit; the regenerator chambers being so disposed that those on the same side of the axial division wall are all traversed at the same time either by gases for combustion or by combustion products. In the oven shown, which may be heated by rich or poor gas, or by both together, air is drawn in through a passage 1 and passes to compartments 2 and 3 of the regenerator battery on the same side of the oven. From the compartment 2 the air passes into the rear part of a passage 4 and into the combustion flues 5 of the lefthand series, whilst that from the compartment 3 passes to the front of the passage 4 and into the combustion flues 6 of the right-hand series. Poor gas from a main 7 is supplied to the regenerator chambers 9, 10, alternating with the chambers 2 and 3, from which it passes respectively to the near and front portions of a passage 11 and thence to the flues 5 and 6 of the left and high hand series, the paths being similar to those of the air. The combustion products passing down the flues 12, 13 of the left and right hand series pass respectively into the near and front portions of passages 4<1> and 11' corresponding with the passages 4, 11, which communicate with regenerator chambers 2<1>, 3<1>, 9<1>, 10<1>. Fig. 6 shows the paths of the gases through the regenerators and flues, the regenerators, passages, and flues traversed by each path forming one of the units referred to above. The regenerator chambers 9', 10' are connected to a passage 16', which communicates by means of a valve (not shown), with the passage 1<1> leading through a reversing valve to the chimney. On reversal, communication between the passages 16' and 1<1> is cut off, the corresponding passages 16 and 1 being connected. Rich gas may be supplied from a main 20 to ducts beneath the flues; when this is used alone, all the regenerator chambers are used for heating air. An oven of similar construction with provision for heating by rich gas only is also described, the regenerators being used for air-heating only.
