Title: Improvements in or relating to sheet feeding devices for folding machines or similar machines for operating upon sheets
IPC: F24C7/06
Filed: 1931-03-10
Abstract: 367,204. Feeding sheets. SPIESS, G., 78, Zschochersche Strasse, Leipsic, Germany. March 10, 1931, No. 7424. Convention date, May 6, 1930. [Class 100 (i).] Sheet separators, carriers, and guides; feedtables.-In connection with a sheet-feeding device for folding or similar machines, the sheets may be fed automatically from a pile 4 over an adjustable feed-table 12, 13, which is arranged in conjunction with a semi-automatic feed device comprising rollers 15, 16 which can be used as an alternative to the automatic feed device. The automatic feed device shown is of the combing-roller type in which the sheets are fed from a fanned-out pile 4 to a feed roller 9, whence the separated sheet passes over a guide 10, to a continuously driven feed roller 32, which is arranged to maintain its drive in all positions of adjustment of the feed - table. From the section 13 of the feed-table the sheet passes over a guide 14 to the rollers 15, 16 which act as forwarding rollers, and finally over a guide 17 to the inclined rollers 1 of a table which leads the sheet to the folding machine. When a semi-automatic feed is desired, the drive for the automatic feed is thrown out, and the guide 14 is removed. A pile of sheets is placed over the sections 12, 13 of the feed-table, and the fanned-out front of the pile is placed on a plate 47 arranged adjacent to the separating rollers 15, 16, the adjacent parts of which move in opposite directions and thus act to separate and forward the sheets in succession to the rollers 1. The feed-table can be adjusted in order to secure the correct slope for'the semi-automatic feed. The right end of the section 12 is pivoted to arms 18 which are pivoted to the machine frame, and the pivot 11 which joins the sections 12, 13 is carried by adjustable racks 19 which move in guides 22 which can swing about the axis of the pinion 20 which operates the racks 19. The lower end of the section 13 can be raised and lowered by means of nuts 23 which are engaged by screws 25 fitted with operating cranks 24. The screws 25 are carried by pivoted cradles 26 which can be swung around pivots 27 by means of spindles 30 operated by cranks 28. The automatic and semi-automatic feeds are driven by adjustable friction gears from a shaft 39, and a coupling permits the automatic feed to be thrown out of gear.

Title: Improvements in electric discharge devices
IPC: H01J25/64
Filed: 1945-03-23
Abstract: 604,674. High-frequency discharge apparatus. WESTERN ELECTRIC CO., Inc. March 23, 1945, No. 7462. Convention date, March 23, 1944. [Class 39 (i)] An electric discharge tube comprises means for producing a circularly-symmetrical electrostatic field whose radial potential gradient at any point is approximately proportional to the radial distance of that point from the axis of the field, means for injecting ions or electrons into the field in a direction normal to the radius at the point of entry with a velocity such that in the absence of any high-frequency field, their velocity is unaltered at the point of entry, and a resonant utilisation circuit coupled to the field by hollow D-shaped electrodes 11, 12, Fig. 1, whereby some of the electrons or ions traverse the field in a series of curved paths and yield energy to the resonant circuit each time they cross the gap between the D-shaped electrodes 11, 12. Preferably, electrons are used, in which case the radial field decreases from the centre proportionally to 1.12x10<-14> f<2>r<2>, where f is the resonant frequency of the utilisation circuit and r is the radius. The desired field distribution is obtained by a plurality of semi-circular strip-like electrodes 23 connected together by suitably designed resistances 26 and insulated from the D-shaped hollow electrodes 11, 12 by mica members 22. A collector electrode 24 is provided. Electrons injected when the electrode 11 is momentarily positive are accelerated to a velocity too great to traverse a curved path and will be collected by the electrode 20, but electrons injected when the electrode 11 is momentarily negative will be retarded and caused to follow curved paths within the field as required. The Specification as open to inspection under Sect. 91 states that the paths of the electrons or ions within the field are a series of decreasing semi-circles. This subject-matter does not appear in the Specification as accepted.

Title: Method of producing organic acids
IPC: C07C51/16
Filed: 1928-03-12
Abstract: 287,064. Hale, W. J., and Haldeman, W. S. March 12, 1927, [Convention date]. Formic. acetic, propionic, butyric, and other aliphatic acids are produced from the corresponding primary alcohols of boiling-points below 350‹ C. by treating the vapour, which may be diluted with an indifferent gas such as nitrogen, water-vapour or air, with a reduced metal to effect dehydrogenation, and immediately after with the unreduced metal oxide to oxidize the aldehyde to acid. Suitable catalysts are copper, silver, mercury, and noble metals such as gold. A promoter may be used, for instance cuprous oxide containing 1 per cent of silver. In an example, a tower is filled with the last-mentioned catalyst, the temperature being 350‹ C. at the top and 280‹ C. at the bottom. Commercial 80 per cent alcohol is vaporized and passed into the tower upwardly. Reduced metal mav be taken from the bottom of the tower, allowed to oxidize in the air, and returned to the top of the tower where acetic acid vapour escapes.

Title: Improvements in rim latch
IPC: E05B55/00
Filed: 1941-06-25
Abstract: 549,395. Latches. ZION, A. June 25, 1941, No. 7975. [Class 44] In a door latch (shown as a night latch) in which the bolt is withdrawn by a retractor pin which can also dead-lock the bolt in fully shot position, the pin 46 carried by a radial arm operable by knob 49 is biased by spring 51 to the deadlocking position, Figs. 4, 5, in which it rests against a stop 50 and is positioned in line with the rear end of a bar 35 projecting rearwardly from the bolt head, and it also cooperates with recesses in the edge of an aperture 43 in the bolt tail 34 so that the bolt may be moved to a partly retracted position from which it is releasable only by pushing in the bolt as by closing the door, the bolt and pin then returning to the fully shot dead-locked condition shown, or may be further moved to a fully retracted position from which it returns to the partly retracted position above referred to on release of the knob, or may be still further moved to a fully retracted position in which it is held until released by a reverse movement of the knob. As shown, the bolt has two lateral recesses 44. 45 separated by a hump 45a, Fig. 3. A- similar pair of symmetrically disposed recesses 47, 48 are also provided so that the bolt is reversible for right-hand or left-hand use. When pin 46 is moved clockwise, Fig. 4, it withdraws the bolt until it snaps over a shoulder 57 into recess 45. In this condition the bolt is partly retracted and is held by shoulder 57 preventing return movement of the pin. When the bolt is pushed in, shoulder 57 releases the pin which is then moved anticlockwise by spring 51 until arrested by the upper edge of bar 35. When the bolt subsequently shoots, the pin rides over the end of bar 35 to deadlocking position. If the pin 46 is given a further clockwise movement it rides over hump 45a into recess 44 as in Fig. 3. In this position the bolt is fully retracted so that the door may be opened, but when the knob is released pin 46 returns to recess 45 holding the bolt in the partly retracted position above described. If however, pin 46 be given a still further clockwise movement, the bolt is further retracted and the pin returns over hump 45a into recess 45 and holds the bolt in fully retracted position until the pin is given an anticlockwise movement by the knob. The bolt tail 34 and bar 35 are conveniently formed integral as a sheet-metal stamping secured at 36 in a groove at the rear of the bolthead 32. The spring 41 which shoots the bolt is disposed around bar 35 in compression between the bolt head and a washer 42 against a fixed abutment 40 which also has a groove guiding the free end of bar 35. Outside operation is effected by a cylinder lock 56 the connecting bar 55 of which rotates a member 53 journalled in the cover plate 22 of the casing and having a pair of arms 52 (one shown) one of which engages pin 46.

By pressing an unshaded button in board AA he directs a letter to its final destination, but by pressing a shaded button he effects a preliminary sorting which requires the pressing of a button on board BB to control the final destination. The arrangement of the buttons on the boards corresponds roughly to the arrangement of the compartments used in manual sorting. Fig. 2 shows the electrical circuits. Alternating current is supplied to the mains S<SP>1</SP>, S<SP>2</SP>, S<SP>3</SP> so that S<SP>2</SP> carries full wave current, S<SP>1</SP> positive half-wave current and S<SP>3</SP> negative half-wave current. The pressing of an unshaded button PK2 on board AA distributes negative half-wave current to relays C and D and positive half-wave current to relays E and F. The relays D and E then operate to prepare the circuits which direct the letter to its destination. On the other hand, the pressing of a shaded key PK1 and the key SKI of key-board BB, the relays D and G are operated to cause the direction of the letter to its destination. Specification 473,996 is referred to.
