Title: Improvements in or relating to boat raising and lowering gear
IPC: B63B23/04
Filed: 1929-05-03
Abstract: 333,186. Dixon, L. A., Peat, J. B., and Tees Side Bridge & Engineering Works, Ltd. May 3, 1929. Davits.-The davit 16 is mounted on a stand 12 having an inclined track 14 on which runs a roller 17 carried by the davit the rail of which carries a second roller 18 constrained to move in a dissimilar path by working in a second track 19 so shaped that the vertical component of the movement of the roller is greater than the horizontal component. The arrangements cause the davit 16 to luff during its outboard travel and by giving the track 19 an inboard inclination at 23 the davit is locked in its outboard position. In a modification the track 19 is straight but inclined inboard. The gear for controlling the davit is combined with the fall gear and comprises a fall passed over rollers 27, 28 on the davit arm and stand respectively and thence over the roller 29 on the davit head over the fall pulley 30 and thence back on to the davit head. In variations a quadruple purchase is given by passing the fall over additional rollers on stand and davit, or separate gear may be employed for controlling the davit in which case a six-fall pulley block system may be used for controlling the boat.

Patent GB-414199-A (GB)
Title: Improvements in or relating to bacon slicing machines and the like
IPC: B26D7/01
Filed: 1933-05-13
Abstract: 414,199. Slicing - machines. LAMBERT, F. T., 49, Park Road, Wandsworth, and PATERSON, A. E., 32, Asylum Road, Peckham, both in London. May 13, 1933, No. 13960. [Class 28 (ii).] In a slicing-machine having a vertical meat plate or holder pivotally movable to compensate for a taper in the substance being cut, the pivotal movement is effected by a lever i pivoted at either side of the feed table and connected by a link k to the holder g at an intermediate point in its length, the lever i being located to the rear of the holder with its free end movable over or towards the pivot h of the holder so as to approach a stop l which, during the feed movement, causes the lever i to draw the holder g back from its oblique position. The holder is pivoted to a frame f having slotted lugs f<1>, f<2> to engage the usual posts e, and the lever i is pivoted at j to the frame and carries a segment i<1> having a slot i<2> which has, as its centre, the connection point g<1> when the holder is parallel with the slicing plane. The pin k<1> is movable along the slot and is clamped in position by a nut k<2>. The pivot h of the holder g is also provided with a clamping-nut h<1>, and the stop l is a post which is carried by a bracket l<1> secured to the usual support m for the underside of the article. In use, the substance is secured to the holder g which is then swung until the front face of the substance is parallel to the cutting plane. The holder is clamped temporarily in this position by the nut h<1>. The link k is then moved along the slot, thereby swinging the link i towards or over the pivot h until it contacts with the stop l. The nut h<1> is then released. The magnitude of the angular correction varies with the position of the link k relative to the slot i<2>, and in all positions of adjustment, the holder returns to parallelism with the cutting plane as the last slice is cut. When it is desired to use the holder without the angular correction, the holder may be locked by a spring-controlled catch f<4>. In a modification, the link i is itself slotted for the link adjustment and is operated by a sliding tappet rod which contacts at one end with the stop l and, at the other end, carries a block which is engaged by a forked end of the lever i. A tilting-ring locking device is provided. Specification 266,819, [Class 28 (ii)], is referred to.

Title: Improvements in and relating to bread slicing machines
IPC: B26D7/06
Filed: 1937-05-20
Abstract: 488,810. Endless-chain conveyers. NATIONAL BREAD WRAPPING MACHINE CO. May 20, 1937, No. 14042. Convention date, Feb. 12. [Class 78 (i)] [Also in Group I] A bread-slicing machine comprises a delivery table 28 to which the sliced loaves are fed, chains 30, at the sides of the table, carrying spaced pushers 33 which engage the loaves individually at the gap between the support 25 and the table, and means for advancing the loaf in proximity thereto to a position in advance of its pusher, so that, when the loaf is subsequently engaged by the pusher, it is in the correct position for presentation to the wrapping machine. In Fig. 1, the advancing means comprises a bar 37 extending between arms 36 which are rotated by chain and toothed gearing in synchronism with the pushers 33. In modifications, the bar 37 is arranged on oscillating arms driven by a cam, or the advance of the loaves is effected by rods extending between sprocket chains arranged above the table 28. In the construction shown in Fig. 5, two sets of pushers 65, 71 are carried by two sets of chains 66, 72, the pushers 65 on the chains 66 being of such height that they engage the loaves individually at the gap between the support 25 and the table 28, and then travel along and protrude through the table 28 until they are retracted from the table through the spring-pressed trap door 70. The pushers 71 on the chains 72 are of such height that they travel bethe table 28 until, in virtue of the chains 72 being deflected by sprockets 75, 76, they are raised through the spring-pressed trap door 77 and then travel protruding through the table, each to engage the loaf left upon the table by the previously withdrawn pusher 65. This construction may be varied by both sets of pushers being carried by a single pair of chains, the pushers in this case being pivotally carried by the chains and actuated by springs and two stationary cam rails. The cam arrangement is such that the pushers of one set are positioned to receive the loaves at the gap and are subsequently withdrawn through a trap door corresponding with the door 70, whilst the pushers of the other set are inoperative at the gap, but are projected through a trap door corresponding with the door 77, to engage the loaves left on the table 23 by the withdrawn pushers. Fig. 3 shows a modified form of pusher having a vertical pushing face 51 and a slanting rear face 52, this form being suitable when the loaf is likely to be tilted in the direction opposite to that shown in Fig. 1. In Fig. 1, the loaves are fed to the knives 24 by feed chains 26, 27 driven through a variable speed gear. The support 25 is slotted to extend between the knives. The support 25 and chains 26, 27 could be arranged horizontally instead of at an angle.

Title: Textile assistants
Filed: 1933-05-15
Abstract: Products stated to be useful as emulsifying agents are obtained by treating a secondary amine with an alkylating agent and a benzyl halide, either being used first, and sulphonating the resulting quaternary ammonium salt.  The alkylating agent employed must be capable of introducing an alkyl group containing at least six carbon atoms.  In a modification of the process the sulphonation step is avoided by using a sulphonated benzyl halide. In examples: (1) dimethylamine is treated with cetyl bromide and the free base liberated with caustic soda treated with benzyl chloride.  The resulting benzyldimethyl hexadecylammonium chloride is sulphonated with chlorsulphonic acid; (2) diethylamine is benzylated and after treatment with cetyl-p-toluenesulphonate is sulphonated.ALSO:Products stated to be useful as wetting, cleansing, foaming and dispersing agents are obtained by treating a secondary amine with an alkylating agent and a benzyl halide, either being used first, and sulphonating the resulting quaternary ammonium salt.  In a modification, the final step is avoided by using a sulphonated benzyl halide.  An alkyl radicle containing at least six carbon atoms must be introduced by the alkylating agent.  In examples, (1) dimethylamine is treated with cetyl bromide and the free base liberated with caustic soda; benzyldimethylhexadecyl ammonium chloride obtained by treatment of the base with benzylchloride is then sulphonated with chlorsulphonic acid.  The product is a stripping agent which may be used in the manner described in Specification 400,239; (2) diethylamine is benzylated and after treatment with cetyl-p-toluenesulphonate is sulphonated.  The use of the products in the textile, leather and paper industries is mentioned.

Filed: 1952-06-05
Abstract: 713,709. Electrode materials. SOC. ANON. POUR LES APPLICATIONS DE L'ELECTRICITE ET DES GAZ RARES-ETABLISSEMENTS CLAUDE-PAZ ET SILVA. June 5,1952 [June 8, 1951], No. 14215/52. Drawings to Specification. Class 39(1) The alkaline-earth oxide coating of a cathode for a gas-discharge tube such as a lamp, is coated before final activation with a layer of poorly emissive refractory oxide which is pervious to the discharge current. Suitable oxides are those of aluminium, magnesium or beryllium. In one form a hollow molybdenum electrode is coated internally with a mixture of barium peroxide and tantalum which is then heated to red heat in an atmosphere of nitrogen and hydrogen to form a black reaction product. The whole electrode including the leads is then coated with alumina by spraying on ethyl acetate suspension. The layer reduces sputtering and has a protective effect until the electrode is finally activated. The coating may also be applied to the product of heating hydrates or carbonates: or to the unreacted hydrate or carbonate, applied in an example to a helical' electrode and a dipped magnesia coating. Poorly emissive substances may also be mixed with the emissive oxides.

Title: Control systems for two-phase ac motors
IPC: H02P3/16
Filed: 1974-04-02
Abstract: 1459599 Control of AC motors UZBEX NI INST ENERGET I AVTOMAT 2 April 1974 14515/74 Heading H2J An A.C. motor having stator windings 1, 2 connected in delta with a capacitor 3 is driven in one or other direction by closure of a switch 6 or 7 which simultaneously completes, via diodes 8 and 9, a circuit to the winding 11 of an electromagnet brake whose consequent energization actuates the brake to release the motor shaft. Opening of the switch 6 or 7 thus simultaneously de-energizes the motor and applies the brake, the selection of switch 6 or 7 (which may be a thyristor) being determined by a three-position controller (not shown) applying a control signal to terminals 12, 13 or 13, 14 to fire the appropriate thyristor 6 or 7. Whilst the motor may be stopped solely by the electromagnet brake, Fig. 1 (not shown), the embodiment shown in Fig. 2 provides additional dynamic braking of the motor when switch 6 or 7 opens, by completing a circuit for halfwave rectified A.C. from the supply 4,5 through the windings 1, 2, diodes 8, 9 and a controlled rectifier 16. The D.C. braking current is applied for a time determined by that required to charge a capacitor 20, the latter time being preset by adjustment of a potentiometer 32. When the motor is being driven, a current flows through capacitor 3 and the primary winding of a transformer 31, whose secondary winding supplies one rectifier 29 of a comparison circuit having a second rectifier 27 supplied from a secondary winding of a transformer 22 whose primary winding is fed by the supply 4, 5. The arrangement is such that the output voltages of rectifiers 27, 29 balance each other when the motor is being driven. Hence no charging current flows in capacitor 20 and a transistor 17 is non-conductive to prevent the application of firing signals to rectifier 16 from a further secondary winding of the transformer 22 via rectifier bridge 18, transformer 21 and diodes 23, 24. When switch 6 or 7 opens, the current through capacitor 3 falls to zero as does the output from members 31, 29, whereby the transistor 17 is made conductive, capacitor 20 starts charging and rectifier 16 is made conductive to allow D.C. braking current to flow. When capacitor 20 is fully charged, the transistor 17 is turned off to produce turn-off of the rectifier 16 at the next current zero to terminate the D.C. braking. The charging time of capacitor 20 is at least equal to the delay between de-energization of the winding 11 and application of the brake element to the motor shaft. Thus the motor will initially be dynamically braked and then mechanically braked, with possibly a time overlap between these operations. The winding 11 will be connected in series with a diode (not shown) during dynamic braking of the motor, the diode being poled to prevent current flow through the winding.

A slidable carriage 2 carries two different originals 3, 4, and can be moved so that first one and then the other is moved into the exposure position for projection on to a roll of printing paper 9 behind a window 8. In the application described, one original is a picture image and the other a textual image, so that the final print is a composite of the two. The reciprocating movement of the carriage is controlled automatically, and is also synchronized with the paper feed. The text is printed first, and exposed for a predetermined time. Then the carriage traverses across to its other position, when the picture is printed, an automatic exposure-regulating device dependent on the gradation being brought into operation. The mechanism is also synchronized with a marking device 11 such as a graphite wheel, which is subsequently scanned by a device operating a cutting means.
