IPC: B26D7/32
Abstract: 135,508. Berkel, C. F. M. van. July 5, 1917, [Convention date]. Cutting slices in succession.-In a stacking mechanism for machines for slicing meat &c., the slice-discharging portion is operated at a speed independent of the speed of the machine. As shown, meat on a reciprocating table 5 is sliced by a rotating knife 3. After each cut the usual slice-feed mechanism feeds the meat on to spikes 12, Fig. 10, carried by vertical members 13 secured to top and bottom chains 14, 15 guided in channels 17, 18 reciprocating with the table 5. At the end of the stroke of the table, when the slice has been completely cut, an arm 28 which, up to that point, has caused the spikes to move with the table, accelerates the chains along their guides to carry the cut slice past a guard plate 40 to discharging arms 46, which, as the chains move, slide between the slice and the members 13. The arms 46 are carried by a vertical rod 47 secured to a shaft 48 having an arm 52, Fig. 4. The arm 52 is pulled down by a spring 65 to detach the slice from the spikes 12 and deliver it to a plate 70. Normally, the arm 52 is held up by a link 53 having an arm 61 pivoted thereto and provided with a roller 60 engaging a cam 59 driven from the main shaft 8 of the machine. The arm 61 is pivoted so that the cam can turn in the reverse direction. A catch may normally retain the rod 47 vertical, being tripped by a link engaged by the arm 28 when the slice is to be discharged on to the stack. The rod 48 may have a cam engaging a spring- pressed roller and acting as a shock absorber at the end of the discharging oscillation of the arms 46. The plate 70 is held at any point on vertical rods 75, each holding means comprising a plate 78, Fig. 13, caused to bind on the rod by a spring 80 and released when desired by a finger piece 79.

Abstract: 347,013. Motor car bonnet fastenings. BIENAIME, R., 10 bis, Boulevard Bonne- Nouvelle, Paris. May 2, 1930, No. 13586. Convention date, Sept. 14, 1929. [Class 44.] A motor car bonnet .fastening comprises a hook c which is pivoted at f to an operating lever g and is pivotally connected at e<1> to a spring- pressed member e. The pivot pin f slides in slots j in a hollow rectangular member c which is attached to the bonnet and against the top plate b<1> of which the spring d bears. The hook engages with a sleeve k which is rotatable on a pin fast to the chassis. The pin is displaced laterally relative to the vertical plane passing through the axis c<1> to obtain a lateral pull on the bonnet. For closure it is necessary to depress lever g which bears at its opposite end against the upper edge of a slot b‹. The downward movement thus given to the hook causes the hook face c<1> to slide over the sleeve k and swing the hook towards the bonnet, as shown in the Figure, until it can engage the sleeve k. Disengagement is effected by raising the lever g so that it bears against a crosspiece c<2> on the hook and rotates the latter out of engagement.

Title: Improvements in and relating to processes for the production of liquid polymerisation products from gases containing hydrocarbons
IPC: C07C2/80
Filed: 1928-05-09
Abstract: 317,344. Epner, C. May 9, 1928. Hydrocarbons; heterocyclic compounds; oxygenated organic compounds.-Liquid polymerization products suitable for use as power fuels are obtained by subjecting methane, gases containing methane such as purified coke oven gas, ethane or other gaseous or vaporous hydrocarbons to the action of a silent electric discharge produced by an alternating field of a frequency of 8,000-12,000 cycles at about 8,000 volts, in the presence of catalysts which promote condensation such as carbides or metal oxide, or salts. The treatment mav be carried out in an apparatus of the Siemens ozonizer type, in which the inner electrode is concentrated sulphuric acid in which a cooling coil is immersed and the outer electrode is running water. If raised temperatures (150-500‹ C.) are used to maintain the products as vapours, electrodes of mercury or easily fusible, alloys such as lead-tin alloys may be used. If the catalyst is a non-conductor. for example alkalized zinc-oxide., it is packed in the annular space of the ozonizer, and it a conductor it is formed as a mirror or coating on the walls. If gases containing carbon dioxide, carbon monoxide, water vapour or alcohol are treated the product contains ketonic and aldehydic compounds; the presence of phenols causes the formation of aromatic compounds with side chains, and the presence of nitrogen, the formation of ring compounds containing nitrogen. The presence of oxygen-containing substances in the product may be prevented either by using in addition in the apparatus a hydrogenating catalyst or by subjecting the product to a subsequent catalytic hydrogenation. The gases may be treated under pressure. Specification 223,543 is referred to.

Title: Improvements relating to heating devices for motor vehicles
Inventor: WORMS FRED SIMON
IPC: B60H1/00
Filed: 1952-05-29
Abstract: 714,743. Ventilation TUDOR ACCESSORIES, Ltd. March 27, 1953 [May 29, 1952], No. 13717/52. Class 137. [Also in Group XIII] Relates to vehicle heating arrangements in which air, warmed during passage through the engine cooling-radiator 10 is collected in a collector disposed behind the radiator and discharged through a distributer to the vehicle space. According to the invention the distributer comprises an air-receiving chamber connected by a conduit to the air-collector and by one or more outlet openings to a distributing chamber having openings for the passage of the warmed air to the vehicle space, a shutter being provided for closing either fully or partially the outlet openings from the air receiving chamber. In the form shown the distributer comprises a conical chamber 13 having an inlet for warmed air at one end and outlet ports 16 at the other end. The ports 16 communicate with a distribution chamber defined by the base of the chamber 13 a disc 23 and spaced rings 26 the spaces between these rings constituting air outlets from the distribution chamber to the vehicle space. Cooperating with the ports 16 in the base of the chamber is a shutter 28 rotatable by a knob 30. Attached to the shutter and projecting into the distribution chamber are a pair of diametrically opposed baffles 29 which may be movable with or independently of the shutter. A blower 22 operated by a switch 36 is disposed within the distribution chamber. The arrangement is such that upon actuating the shutter by means of the operating knob 30, to open the ports 16, the baffles 29 will take up the positions shown in the drawing (Fig. 1) whereby warmed air will be directed upwardly and downwardly through the spaces between the rings 26 to the vehicle space. If the knob 30 is now turned so that the shutter closes the ports 16, the baffles 29 will also be moved so that whilst entry of fresh warmed air is prevented by the shutter, the air within the vehicle space will be recirculated through the distribution chamber by the blower, the flow of air through the distribution chamber then being horizontal. It is stated that when the vehicle is travelling at a sufficient speed an adequate supply of heated air will be available without use of the fan. The device may be mounted on the vehicle dashboard so that only the distributing chamber projects into the vehicle space.

Title: Improvements in and relating to hollow cylinders
IPC: F02F1/14
Filed: 1961-04-17
Abstract: A cylindrical reaction vessel, subjected to internal heating, internal pressure and external cooling, has on its outer surface, circumferentially extending ribs which are of a radial dimension greater than lambda/a , lambda being the coefficient of thermal conductivity of the rib material and a  being the heat transfer coefficient between the rib material and the coolant, and of an axial thickness, <PICT:0900294/III/1> <PICT:0900294/III/2> <PICT:0900294/III/3> <PICT:0900294/III/4> adjacent their radial extremities, greater than 80% of the axial length of the gaps between adjacent ribs.  With these dimensions the ribs are kept cool (whereas conventional cooling fins would be hot) and act as pre-stressed reinforcing rings which are in tension while the hot cylinder is in compression.  A hollow cylinder 1, closed by a cover 10 having a liquid coolant chamber 11, has ribs 3, formed either as closed rings, as shown, and interconnected by recesses 6 in a jacket 4, or as a single-start or multi-start low-pitch helix enclosed in a plain cylindrical jacket.  The coolant is supplied through an inlet 7 to gaps 2, which allow intensive cooling of the cylinder, leaving the ribs 3 cool so as to act as pre-stressed reinforcing rings. Alternative ribs cross-sections, Figs. 5, 6 and 7 provide improved cooling and improved reinforcement since each allows an adequate flow cross-section near the cylinder inner wall and a large outer cross-section of cool reinforcing ribbing.  The cross-sectional area f2, Fig. 5, is advantageously greater than that of area f1.

Filed: 1959-04-24
Abstract: 850,206. Circuits employing bi-stable magnetic elements. SIEMENS & HALSKE A.G. April 24, 1959 [April 30, 1958], No. 14084/59. Class 40 (9). [Also in Group XIX] A number of binary digits are stored in an equal number of storage elements under the control of a pulse distributer and are read out after a time period slightly less than the time required for the distributer to pulse all the storage elements in succession. Pulses to be stored are entered on terminal 24, Fig. 2, in synchronism with pulses supplied by pulse generator 19, to open AND gates 11- 14 in succession and store the relevant information in magnetic stores 15-18. The pulses supplied by the generator also act as read-out pulses to the following store so that the information is read out on terminal 25 after a time-delay of n-1 pulses if there are n stores. The input and output terminals can be connected to provide a re-circulating arrangement. Fig. 4 shows a circuit equivalent in which each gate comprises a battery and rectifier such as 34, 30, the output line includes a battery 54 to suppress unwanted zero pulses. Fig. 5 shows each store element combined with its associated AND gate. The combined effect of a pulse generator output on a single loop 74 and an input pulse on a single loop 64 stores 1 in the related core 55. The same pulse from generator 59 passes through read-out winding 75 of the succeeding core 56 to induce an output pulse in loop 69 if 1 is stored there. Writing in also produces output pulses which are of opposite polarity and can therefore be distinguished or suppressed. Storage can be effected of several numbers simultaneously (Fig. 6, not shown).
