Filed: 1974-03-12
Abstract: 1468882 Ink drop printers NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP and SHARP KK 12 March 1974 [12 March 1973] 11054/74 Heading G4H An ink-jet printer incorporates means for monitoring drop formation and charging synchronism. A signal from a detection electrode 101 located in the ink drop path 102 is fed to a phase sync detection circuit 1; if drop formation and charging (using test signals) are in synchronism, then "phase OK" signals B 0  are produced at B. If the signals B 0  persist for longer than a predetermined time T 0  (i.e. if sync is maintained for this time) then the output D of an integrator 203 exceeds a threshold level V 0  (Fig. 3, not shown) and point E(F) goes high (low) to set a flip-flop 3 to produce a "printing ready" signal H so that printing can start. If synchronism is lost after printing has begun, a circuit 8 (which is the same as circuit 2 except that its monitoring period is less than T 0 ) resets flip-flop 3 and also sets a flip-flop 9 to actuate an alarm 10. Means 4 or 13 are provided for resetting flip-flops 3 and 9 when the printer is initially energized.

Title: Improvements in or relating to indicating or control apparatus responsive to temperature variations
Inventor: RAMSAY FRANK RAYMOND FABER
IPC: G05D23/12
Filed: 1948-04-22
Abstract: 648,871. Temperature-responsive actuating-elements. NAPIER & SON, Ltd., D. April 22, 1948, No. 11063. [Class 64(ii)] [Also in Groups XX and XXIX] In apparatus for indicating or control in accordance with the temperature in a high temperature range, i.e. 815‹C.-935‹C., a small bore bulb 10 lies within a zone at the high temperature and is connected by a capillary tube 12 to a Bourdon tube 14 or like device outside the zone. Moreover, at temperatures below the high temperature range the system is full of liquid such as mercury at a pressure above its vapour pressure while at temparatures within the range the liquid in the bulb at least partly vaporizes and the pressure of this vapour determines the pressure in the system and thereby the position of the Bourdon tube. The bulb 10 is formed to have a volume equal to the volume of liquid required to expand the Bourdon tube through the high temperature range so that at the top end of the range the liquid is fully displaced from the bulb. Below the range, thermal expansion of the liquid controls the position of the Bourdon tube. A formula relating the volume and low temperature filling pressure of the bulb and the pressure-volume characteristic of the tube 14 is developed.

Abstract: 118,304. Oubridge, W. A. Aug. 8, 1917. Casting - machines; moulds; castings, extracting. - In casting rings or short tubes, the mould parts are moved, after the casting has solidified, so as to strip it and allow it to fall from the mould. In the case of a rotating mould, this consists of a rotatable but axially fixed ring h, an annular wall a rotated by a pulley w and moved axially by a pinion d<2> and a radial wall e carried by a shaft f which is feathered to slide in the hollow spindle b of the wall a. For casting, the wall a is pressed against the ring h and held by a catch o while the molten metal is introduced through the ring i which has cooling- gills k<1> and asbestos washers l. Excess metal is caught by a hood x having a mica window x<1>. The wall a is then withdrawn by rack and pinion d<2>, the wall c moving with it till a stop g engages a bracket m and the casting is ejected. The spindle b has cooling gills k, and a brake w<1>. When casting tubes, for instance the pots to be cut up to form piston rings, the walls a, Fig. 3, and e may be integral and snags 31 are secured to the ring h and adapted to enter slots in the wall a so that they form a flaring part on the casting and, when the mould parts are separated, they extract it. In this case, the ring h moves axially, being connected by a bolt 44 to a rack slide 46, which can be advanced to introduce the spout of the ladle 49 into the mould. In the case of a non-rotating mould, the cavity is formed by a fixed but adjustable member 6, Fig. 4, and members 1 and 3 carried by spindles 2, 4 and moved, after casting, first together and then the member 1 alone by a pivoted cam plate 15. The mould is provided with a pouring hole 20 and asbestos washers 18, 19.

Patent GB-114878-A (GB)
IPC: C11D13/26
Abstract: 114,878. Young, De N. W. B. April 13, 1917. Soap tublets, bars, &c.-Apparatus for ageing soap in the form of bars or the like comprises a chamber 12, Fig. 1, containing a stationary body of air together with heaters such as coils 14, an endless conveyer provided with free swinging soap-holders 19, and means for feeding and discharging the soap bars. The soap is first carried through a chamber 11 containing air to modify the surface of the bars by absorbing moisture, and, after the formation of a jelly-like skin by subjection to a temperature of 150-220‹ F. in the chamber 12, is carried through a cooling- chamber 13 where the skin is fixed. The conveyer consists of two endless chain belts 17 passing over sprocket wheels. The soap-holders consist of two arms 19, Fig. 9, swinging freely on the chain belts 17, the arms 19 being connected by a cross-bar 18 having a saddle 21 mounted upon it. The saddle 21 has an upward lip 22 at its rear, and a pair of soap-engaging points 21' at its front. The feeding-mechanism consists of an apron 27, Fig. 5, and finger-pieces 28 upon which the soap Lar rests until the soap-holder rises between them lifting the bar. The conveyer is held by vertical guides 29 of which the finger-pieces 28 form continuations. Should two bars of soap adhere and be carried up together, the outer bar lifts a tripplate 30 and disengages a spring-pressed roller 31 which normally is engaged by a lip 32. In the case of slight adherence, the trip-plate 30 will sever the bars; in other cases, the movement of the trip-plate is seen by the operator. To discharge the bars after treatment, the soap-holders are tipped by means of sprocket wheels 17', Fig. 6, and guides 35, which cause the conveyer and its soap-holders to travel at an acute angle with the receiving-apron 33. Fingers 34 engage the soap bars and overturn them on to the apron 33.

Abstract: 370,660. Slicing-machines. BLICK, E. L. and AUTOMATIC SCALE CO., Ltd., Broadheath, Altrincham, Cheshire. April 18, 1931, No. 11524. [Class 28 (ii).] The last-slice holder of a slicing machine is provided with a set of hooks which project for a substantial distance into the meat to render the holder suitable for holding large pieces of meat. The large hooks are automatically withdrawn from the meat as the holder approaches the slicing plane. In Figs. 2 and 3 the usual short prongs 12 are carried on shafts 14 which are operated by a hand-lever 13, connecting links 16 and gearing 17. The handle 13 is locked in the depressed position with the prongs fully projected, by a spring latch 18a which is displaceable laterally to free the handle for retraction of the prongs. The additional prongs 19 are carried on shafts 21 operated by a handle 22 pivoted in alignment with the top shaft 14 and connected by linkage 24 and gearing 25 to the prong shafts 21. The holder frame 2 has lateral extensions 3 shaped to engage the usual clamp posts, and a retaining latch 9 secures the holder in position. In operation the meat is first impaled by the short prongs 12 as usual and the long prongs 19 are then projected into the meat. As the holder approaches the slicing plane, an arm 26 on the lower shaft 21 engages a stop on the reciprocating carriage, the arm 26 being thus swung counterclockwise to withdraw the prongs 19 from the meat. In a modification, Fig. 6, the short prongs 12 are mounted in three opposed sets and are operated by a handle 13, linkage 16 and gearing 17. The long prongs 19 are carried by a plate 31 pivoted at 32 to the holder frame. The prongs are concentric with the hinge 32, and the plate 31 has an extension which engages a stop on the reciprocating carriage to effect the automatic withdrawal of the prongs. The plate 31 may be hinged about a vertical axis. The short and long prongs may be interconnected to be moved into their operative positions simultaneously.

Abstract: 437,194. Bowden mechanism ; racks. TECALEMIT, Ltd., Great West Road, Brentford, Middlesex.-(TÚcalÚmit Soc. Anon.; 18, Rue Brunel, Paris) April 19, 1934, No. 11863. [Classes 80 (i) and 80 (iii)] A flexible member adapted to transmit forces and movements parallel to its axis, comprises in combination a sheath or casing and a metallic or other flexible core the external surface of which is not smooth and on which is wound tightly, in the form of a helix, a wire whose successive turns are not in contact with one another and are held in position only by adherence to the surface of the core without the use of a spacing element. The flexible core may consist of two twisted wires 1, 2, Fig. 1, on which an external wire 3 is wound helically to the same pitch so as to engage the depressions between the twisted wires, this wire sliding in the casing 6. In Fig. 2, the core is a bundle of only slightly twisted wires 4 on which thin wires 5 are wound to form the roughened surface. The outer wire 3 is wound as a helix of opposite band to that of the wires 5 and is shown as being engaged by a pinion 7. In a further modification, the wires 5 are wound as a ribbon of four juxtaposed layers, and the external wire 3, of trapezoidal form, is wound to the same hand as the wires 5. The wire 3 may be subjected to rolling pressure during winding to cause it to be looked in position and further, to enhance the locking effect, the wire 3 may be heated before winding. It may also be heated to a temperature at which it becomes softened so that during rolling it is pressed into the recesses of the coil 5. A rubber band or suitable heat-resisting material may be interposed between the central core 4 and the intermediate layer 5 to give increased flexibility to the cable as a whole and avoid possible relative movement between the elements thereof. According to the Provisional Specification a material capable of increasing the adherence between the external helix and the core may be arranged between these elements. Specification 380,204 is referred to.
