Abstract: 340,835. Slicing-machines. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT VERVAARDIGINGVAN SNIJMACHINES VOLGENS VAN BERKEL'S PATENT EN VAN ANDERE WERKTUIGEN., 33, Boezemsingel, Rotterdam, Holland. Feb. 5, 1930, No. 3930. Convention date, Feb. 5,1929. [Class 28 (ii).] A slicing-machine of the type having a disc knife journalled at the end of a swinging arm which is journalled in a member integral with the machine frame and which extends bridge-wise across the feed table or like substance holder, is characterized by the under table on which the feed table is mounted being displaceable or removable to permit the meat to be clamped without obstruction by the bridge member. As shown, the knife 7 is carried by an arm 6 journalled in the bridge member 2, 2<1> and is driven in known manner by a motor 8. The feed table 4 is slidable on a bar 31 on the under carriage 9 which is stationary during the slicing, but is slidable, to facilitate the operation of the meat clamp (not shown), on guide bars 10, 11. The feed screw 13 is journalled in lugs 12 on the under carriage whilst the ratchet operating mechanism is carried by the stationary frame part 21, said mechanism comprising a spring-pressed pawl 14 pivoted to a rocking member 17 which is actuated by a link connecting it to the knife arm 6. The member 17 is journalled on a stationary sleeve 18 containing a spring-pressed plunger 20 which is pressed back by the end of the feed screw when the under carriage is slid into its operative position. When the under carriage is retracted, the plunger 20 moves forwards and its cone-shaped end, acting cam-wise, forces the pin 25 outwards. The pin 25 engages a pin 26 projecting from the side of the pawl 14, the pawl thus being pressed outwardly to prevent it from fouling the teeth of the ratchet wheel 15 as the wheel is re-positioned, with the feed table, in its operative position. The usual ratchet shroud or regulating cam 30 is provided. The under table may consist of an open frame carrying a slab over which the substance slides. A pusher may be used for effecting the intermittent feed motion.

Title: Improvements in or relating to Telegraphy.
IPC: H04L27/24
Filed: 1916-03-24
Abstract: 105,089. Muirhead & Co., and Squier, G. O. March 24, 1916. Duplex telegraphs; receiving systems and apparatus; transmitting systems and apparatus. - In a method of signalling by varying the amplitudes of the half-waves of an alternating current as described in Specification 22265/14, the impulses of opposite polarity are obtained from a direct-current source by means of a commutator which is driven synchronously with an automatic transmitter. The receiver may be tuned to the frequency of the signalling-impulses. In the arrangement shown in Fig. 1, impulses of opposite polarity are sent to the line A from one or more parts of the battery E, E<1>, E<2> by means of a commutator H driven synchronouslv with an automatic transmitter C. The transmitter comprises a conducting-drum c, over which a tape D passes, and two contact-arms c<1>, c<2> adapted to engage the drum through perforations in the tape. The transmitter C operates through magnets, F, F' to vary the number of cells of the battery connected to line. The operation of the arrangement is as follows. When neither of the contact-arms c<1>, c<2> engages the drum c, the magnets F, F<1> are de-energized, and a portion E of the battery sends ' spacing ' currents of opposite polarity to line A by means of the commutator H through contact g, armature G, contact g', and armature G<1>. To send a dot signal, the arm c<1> engages the drum C, thereby energizing the magnet F from the battery f to cause the armature G to engage the contact g<2>. The portions E, E' of the battery are then conrected to line through the commutator H. To send a dash signal, the arm c<2> engages the drum c, thereby energizing the magnet F<1> to cause the armature G<1> to engage the contact g'. The portions E, E<1>, E<2> of the battery are then connected to line through the commutator H. The receiver J may be of the form described in the above-mentioned Specification, and may be kept in a state of constant oscillation by the received impulses, the amplitude of the oscillations being increased by the dot and dash impulses. The circuit connexions at the end of the line may be similar to those described in Specification 12731/98. In the modification shown in Fig. 3, the transmitter X is inductively connected to the line A through an earthed inductance K, and the receiver J is placed in a circuit containing a condenser j, and is inductively connected to the line. The amplitudes of the half-waves may be varied by varying the resistance in the circuit or by varying transformer connexions.

Filed: 1953-02-18
Abstract: 745,535. Blank punching. GENERAL ELECTRIC CO., Ltd. Feb. 4, 1954 [Feb. 18, 1953], No. 4558/53. Class 83 (4). A collecting device for use with a blank punching press comprises means arranged to be moved intermittently between the tools of the press and to receive and collect ejected blanks in a pile, pack or stack all facing in the same direction. The device comprises an I-section pivoted bar 5 which is moved into the gap 6 between inclined tools 3 and 4 of a crank-operated press for punching out slotted iron laminae for electric motors from sheet metal. The bar has a curved finger part 7 which enters one of the peripheral slots in the punched lamina as it is ejected from the punch 4 so that the lamina hangs on the lower flange 8 of the bar 5 and slides towards the lower pivoted end of the bar where it is arrested by a removable stop 9. The bar is actuated by an eccentric 10 on the crankshaft 11 of the press and connecting rod 13 carrying a knuckle-pin 14 which moves in a right-angled slot 15 in a stationary plate 16. The knuckle pin carries a plate 17 attached to a mounting bar 22 which supports the bar 5. The lower end of the mounting bar is held by, but allowed to slide through, a shoe 23 pivoted on the press frame. The portion 15A of the slot imparts longitudinal movement to the bar to move it into and out of the press and the portion 15B moves the finger 7 of the bar towards and away from the top tool 4. In a modification the bar 5 is shortened to deliver punched blanks to a detachable magazine and the tip of the bar is spring-loaded by means 25 to allow it to dwell on the top tool for a short period. The mounting bar 22 in this modification is of dovetail section and pivotally supports the bar 5 on an adjustable shoe 24. A stabilizing bar 26 arranged alongside the bar 5 eliminates any sideward swing of the blanks during their descent. The detachable magazine consists of two I- section beams 27 and 28 fastened at their lower ends to opposite sides of a spacing piece 29 and at their upper ends to a bridge 33 on the mounting bar 22.

Title: Improvements in textile yarns and the manufacture thereof
IPC: D02G3/22
Filed: 1933-02-15
Abstract: 415,054. Yarns. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and SOWTER, P. F. C., c/o British Celanese, Ltd., Spondon, near Derby. Feb. 15, 1933, No. 4631. [Class 120 (iii).] A composite yarn comprises a fibrous component consisting of continuous filaments all or some of which have been converted into fibrous lengths, and a continuous thread, which is completely surrounded by the fibrous component. The continuous thread may consist of continuous filaments. The yarn may be produced by stretching a continuous filament yarn doubled with a yarn of greater length, so that the continuous filament yarn is broken into fibrous lengths, and the longer yarn straightens out ; the breaking is preferably effected by passing the composite yarn through rollers rotating at differing speeds. The final yarn may be twisted to assist in the covering of the core by the fibres. The breaking may be facilitated by arranging that the component of the composite yarn to be broken is weaker than the continuous component ; or the composite yarn may be treated with a softening agent, the resistance of the two yarns to softening differing by reason of their differing twist, or by giving one yarn a preliminary treatment e.g. with an oil, so that it resists the softening agent. Alternatively, the extensibilities of the two components may be made different e.g. by adding oils or pigments to the spinning solution the extensibility may be reduced, whereas by adding high boiling point solvents and/or decreasing the draw-down it is increased. A specially strong material may be used for the continuous thread e.g. one containing filaments which have been stretched beyond their elastic limit. It may be arranged that the stretch requisite to break one component yarn into fibrous lengths is sufficient to stretch the continuous component beyond its elastic limit but without breaking it, whereby its strength is increased. A suitable stretching bath for cellulose acetate contains 47-53 per cent dioxane in water, the stretching run being 20-100 feet; other suitable stretching baths for cellulose acetate are described in Specification 397,137, and for regenerated cellulose in Specification 415,055. The components may be doubled after breakage of the filaments of one component, e.g. the two components may be led separately into a softening bath at different speeds, and drawn out together so that the slower fed yarn is stretched to breaking point, both yarns being collected and twisted, if desired, after the broken filament yarn has passed over a sharp edge or abrasive material to cut and /or lift the fibres to impart a woolly appearance. In order to enhance the woolly appearance, the yarn, after removal of the softening agent by evaporation or washing, may undergo a shrinkage treatment e.g. as in Specification 380,504, [Group IV], after which the yarn may be slackly wound. As an alternative to breaking by stretching, the yarn may be passed over abrading or cutting means.
