Abstract: 731,738. Sales and sale service. NABEIT, I. Feb. 27, 1953 [March 4, 1952; Jan. 15, 1953] No. 5643/53. Classes 27 and 116. [Also in Group XXV] Apparatus for vending benzine, oil or other goods comprise a cabinet with compartments for the goods provided with individual lockable doors having key-operated locks; keys for the locks are sold to customers who can then gain access to a compartment when required but the key is retained in the lock of an opened compartment and can be removed only by an attendant. As shown, a cabinet is divided into compartments each closed by a door 1, and each door is provided with a keeper 3 for a lock bolt 4 of a lock 5 attached to a cabinet wall 9. The cabinet is also provided with a hinged door 7 which is lockable by means of a known form of lock. The lock 5 is operated through a bar 12 by a key operated lock mechanism of known form, to move the bolt 4 to the right in Fig. 4 to open the lock 5. During this movement, the bolt 4 is blocked against a return by an arm 13 attached to the bolt 4 and which during retraction of the bolt releases a spring loaded bolt 19 carrying a blocking disc 17. Continued retraction of the bolt 4 by the key-operated lock mechanism to the fully open position displaces a shoe 20 which lifts a spring-loaded hinged blocking arm 26 on which the bolt 4 then slides to permit opening of the door. Upon closure of the door and operation of the key operated lock mechanism in the reverse direction, the bolt 4 partially reenters the keeper 3 to the point determined by the abutment of the arm 13 and disc 17 and the bolt is blocked against retraction by the arm 26 which rides down an inclined edge 29 of the shoe 20. The shoe 20, to which access is gained through the door 7 is pushed forwards by a handle 28 to permit opening of the door 1 and the release of the arm 13 by depression of the bolt 19. The bolt 4 can then be moved to the fully shot position by the key-operated lock mechanism, the key withdrawn and the shoe pushed forward to return the parts to the position shown in Fig. 4.

Title: Improvements in Methods of and Apparatus for Exerting Pressures or Producing Striking Impulses.
Inventor: GILL HUBERT ALEXANDER
IPC: B30B15/16
Filed: 1917-04-24
Abstract: 111,238. Gill, H. A., (General Briquetting Co.). April 24, 1917. Machines and apparatus; presses; working valves; hydraulic transmission of power. - In apparatus for intermittently exerting pressure on material, the pressure-exerting member is operated from a power member through a liquid link, the resistance of which is momentarily diminished so that the power member acquires additional momentum which is afterwards imparted to the pressure-exerting member. In a briquetting-press, the movable die 14, Fig. 1, carried by a ram 16, is lowered on to the work 13 by pressure liquid passing from a vessel 23, through pipes 27, 25, to a space 28. The vessel 23 is supplied from a pump, and communicates with a vessel 45 containing compressed air &c., a float 44 preventing the air from mixing with the liquids. Valves 48, 36 are operated to close liquid-supply and exhaust pipes 27, 47 and admit steam to a cylinder 33, a plunger 31 being thus forced into the liquid in the space, 28. The pressure increases until the plunger head clears a chamber 41, when it is diminished owing to the capacity of the liquid container being increased, with the result that the plunger suddenly moves forwards and re-establishes the pressure. The energy absorbed by the plunger is imparted to the ram during the remainder of the stroke. The valve 48 is then operated to open the exhaust 47 and the ram is raised by means of the lifting pistons 20. During the return stroke of the plunger 31, the liquid in the chamber 41 is forced back through a by-pass 42, Fig. 5, provided with a check valve 43, into the space 28, the by-pass and check valve being arranged in the plunger, if desired. An emergency cushioning-device between the piston 32 and the top of the hydraulic cylinder consists of a boss 39 on the piston, and a recess 40 full of oil.

Abstract: 415,465. Binders for periodicals &c. CATON, A. A., 30, Bicknell Street, Blackburn. Feb. 25, 1933, No. 5817. [Classes 16 and 146 (i).] In a binder for the preliminary or permanent binding of sections such as periodicals or the like, of the kind wherein the sections are assembled on tapes, cords, wires &c. placed transversely to the plane of the cover and inserted and retained in slits, slots, or holes cut in the folds of the sections by long wires or the like, cords K which are a comparatively accurate fit in the slits M are retained in the sections N by means of short lengths L of wire or other rigid or comparatively stiff material placed between the cords and the innermost leaves of the sections, one length being used in each section for each cord. The binder may comprise a back A and two hinged cover boards B. The cords K are each secured at one end and extend across the back A, and each cord passes through a hole D <1>, around a long piece of wire E (not shown in Figs. 1 and 5), and back again through the hole D<1>, through another hole D2, around the wire E, and out again through the hole D<2> the friction between the cords K, the holes D<1>, D , and the wire E holds the cords tight when once they have been tightened. In a modification, the free ends of the cords are attached to a rotatable rod mounted behind the centre board A, and a detent co-operates with depressions in a plate secured to the rod to prevent inadvertent reverse rotation of the rod. In another construction, the centre board A is dispensed with, the side boards are split, and the cords are laced through holes provided in the inner portions of the side boards. When the requisite number of sections have been secured in the binder, the sections may be made into a permanent book by glueing, rounding, grooving, trimming, and casing. According to the Provisional Specification, the cords may be wholly or partly of extensible material, and the centre board of the binder may be of a springy or flexible nature so that it can extend as the binder is being filled.

Title: Improvements in the production of porous sintered metal bodies
IPC: H01M4/80
Filed: 1951-03-16
Abstract: 678,138. Powder metallurgy. BADISCHE ANILIN- & SODA-FABRIK. March 16, 1951 May 11, 1950], No. 6330/51. Class 83 (iv). In a method of producing porous metal bodies by sintering a metal powder mixture, the mixture has a piled weight of less than two kilograms per litre and is obtained by the thermal decomposition of a mixture of the corresponding metal carbonyls. In an example, as applied to the production of an electrode for an alkaline accumulator, a vaporous mixture of 50 parts by weight of iron carbonyl and 50 parts by weight of nickel carbonyl has added to it about 10 per cent of its volume of carbon monoxide and is led through a heated vessel. The nickel-iron powder thereby deposited is sintered in hydrogen at 900‹ C. to form a porous band 1 mm. in thickness which is locally compressed to form a lattice and impregnated with cadmium hydroxide to produce a negative electrode or nickel hydroxide to form a positive electrode. The method may be used for producing other bodies using other metal carbonyl mixtures such as iron carbonyl or nickel carbonyl with cobalt carbonyl or molybdenum carbonyl. Porous plates or cylinders of nickel-molybdenum powder may be used as filters for corrosive liquids.

IPC: G01S13/60
Filed: 1970-02-10
Abstract: 1293881 Radar PYE Ltd 19 April 1971 [16 Feb 1970] 6415/70 Heading HAD [Also in Division G4] In a Doppler-difference signal radar processor, pulses are generated at a repetition rate equal or related to the frequency of that signal, a gate initiates at least one counting period when a predetermined number of pulses are generated successively and a known proportion of the pulses during each counting period is counted. In the embodiment-for a traffic metering system-pulse trains of opposite polarity issue from a monostable 78 at outputs 80, 82, that from output 80 being fed to a gating means consisting of an integrator 84 and a monostable 86. When, e.g. twenty pulses are received in succession transistor 88 conducts and monostable 86 produces a pulse of duration such that a count of pulses from output 82 in that duration are directly readable as m.p.h. A decade counter 98 feeds a similar counter 102 to afford a count between zero and 99. The counters retain their counts until the next counting period, resetting of counters 98, 102 being effected by a gate 105. The number of vehicles passing the radar is given by a counter 110. The length of vehicles is afforded by a gating circuit 112 (each cycle of the Doppler-difference signal, for quoted radar parameters, corresponds to a length of 2 cms.), and a counter 114, which is reset simultaneously with counters 98,102. To measure the gap between successive vehicles it is assumed that they travel at constant speed: D/A converter 116 produces a current proportional to the readings of counters 98, 102, the current is fed to a NAND gate 118 which also receives the output of integrator 84, and gate 118 output is fed to an integrator 120 which incorporates a capacitor and a trigger circuit "fired" each time the charge on the capacitor reaches a predetermined magnitude, the integrator thereby providing a pulse output of rate proportional to the speed of the leading vehicle; thus a counter 122 has a count proportional to inter-vehicle spacings. Radar head.-A radar head is embedded in the road surface and is arranged to transmit a beam at, e.g. 45 degrees to traffic motion direction; other heads are also provided, Figs. 1, 2 (neither shown). A radar head construction incorporates a loaded horn aerial arranged to avoid entry of water, and a Gunn diode selfoscillating mixer to afford the Doppler-difference output, Figs. 3, 4, 5, 8 (none shown).
