Title: Improvements in hard soldering mixtures and hard soldering processes
IPC: B23K35/34
Filed: 1933-03-23
Abstract: 415,181. Solder compositions. LITTLEDALE, H. A. P., Crabtree, Streatley-on- Thames. March 23, 1933, No. 8712. [Class 83 (iv).] Metals and their alloys, particularly gold, silver, platinum, copper, nickel and silver or gold alloys, are soldered by the use of a soldering mixture containing no flux and no metal in the elemental state, but comprising one or more metallic oxides or salts together with sufficient carbon or carbonaceous material to reduce the oxide or salt to the metallic state and thereby produce the solder in situ. The carbon may be used in the form of or together with glue, gum, paste, starch, &c. and the mixture may be made into a paste or into a dry mass and used in such form or reduced to fluid condition by the addition of water. Glue may be diluted with a liquid preparation of carbon, such as Indian ink. When a carbonaceous cementing material such as glue is used, the mixture also serves to hold the work pieces together prior to and during soldering. The oxides or salts may consist of red or black oxide of copper, precipitated capric hydrate, copper chloride or acetate or verdigris or other copper salts, silver oxide, zinc hydrate, lead dioxide or carbonate, tin oxide or dioxide, or antimony trioxide. Mixtures of oxides may consist of 50 per cent of copper hydrate, with 30 per cent of zinc hydrate and 20 per cent of tin dioxide, or 66 per cent of silver oxide with 22 per cent of copper hydrate and 12 per cent of zinc hydrate, or 50 per cent each of silver oxide and either antimony trioxide or copper hydrate, or 25 per cent of silver oxide and 75 per cent of copper hydrate or 80 per cent of silver oxide and 20 per cent of antimony trioxide. Standard silver or 18 carat gold may be soldered with a mixture of glue and antimony trioxide alone or together with an equal amount up to five times the amount of silver oxide. 18 carat gold may also be soldered with a mixture of glue and equal parts of silver oxide and copper hydrate. When no-gaps in a joint in silver or gold are to be filled up, a mixture of glue with either copper hydrate or antimony trioxide may be used. For gold, gold oxide may also be added in proportions varying from 1 part of gold oxide and 1 part of copper hydrate to three parts of gold oxide and 1 part of copper hydrate. The composition in paste form may consist of 2 parts of oxides,-together with either 5 parts of the substances sold under the Registered Trade Mark " Seccotine," and 3 parts of water or 2À5 parts of anhydrous glue and 5À5 parts of water. A dry mixture may consist of 45 per cent of oxides and 55 per cent of dry glue. Soldering may be effected in a reducing atmosphere.

Title: Improvements in two-revolution printing machines
IPC: B41F3/02
Filed: 1921-03-23
Abstract: 186,360. Mudd, W. G. March 23, 1921. Bed-reciprocating apparatus.-In a two-revolution cylinder printing- machine the cylinder and the bed are driven from a sleeve or bush m fitted with driving-pulleys n and a fly-wheel p, the bush being fitted with a gear-wheel q in direct gear with the impression cylinder, and being geared to a wheel 18 which drives a crank motion for controlling the motions of the bed during the reversal periods. The bush m is also splined to a shaft c by means of keys k, and the shaft, c is reciprocated axially together with a similar shaft t which is geared to it and rotates in an opposite direction so as to move gear-wheels f on the shaft c into and out of gear with two outer divided racks on the printing bed. In the position shown in Fig. 2, the wheels f are in a position to gear with these racks, and the wheels f move the bed until the end of the rack is reached and. a central rack on the bed comes into gear with one of a pair of pinions 30, 32, which are oscillated by crank mechanism driven by gears o. 18, and comprising a sliding frame 24 operated by a crank 21, a reciprocating rack 27 on the frame 24, a pinion 28 in gear therewith, and on the same shaft as the pinion 30, which is geared to the pinion 32 by a rack 31. After the pinions f have finished driving the bed in one direction, the shafts c, t are moved axially to bring a similar gear-wheel u into position to engage the outer racks by a lever 4 with rollers 2, 3 which engage flanges y on the shafts, the lever being oscillated by a cam 9 splined to a shaft 10 geared to shaft c. The cam 9 moves axially against the action of springs @3 fixed to collars 14 on the cam shafts 10, and the movement of lever 4 is limited by fixed stops 17.

Title: A method and apparatus for orienting screws and the like
IPC: B25B23/02
Filed: 1963-03-06
Abstract: 1,015,712. Screw driving machines; machine tool details. June 2, 1964 [March 6, 1963; Jan. 9, 1964], Nos. 8905/63 and 977/64. Headings B3B and B3N. Screws, pins, dowels, and the like, oriented randomly lengthwise, are fed into a sensing position where they are tilted in one direction or another, so that the final orientation of all screws &c. is the same. A screw driving machine comprises a base 2, a column 4, a head 6 carrying a spindle 8 reciprocated by pneumatic means 12, a bowl feeder 14 connected to a screw orienting means 16 by a feed pipe 18, and actuating means 24 for the means 16. Orienting means 16 comprises a channel 30 formed between walls 32, a pusher 38 slidable in the channel, and a block 34 having an aperture 36 through which the screws fall, and pass to a collet 20. Pusher 38 has a notch 40 therein which, in its retracted position is aligned with an aperture in wall 32, the other wall having a metal strip 44 thereon. Pusher 38 is connected to spindle 8 by a Bowden cable 46, and a linkage 48, and is reciprocated in synchronism therewith. In operation, bowl 14 is loaded with screws which pass into pipe 18 and enter notch 40. If the unslotted end of the screw is leading, it will abut strip 44, and will be pushed into aperture 36 as shown in Fig. 5 (not shown). If, however, the slotted end is leading, the screw will rotate until the slot engages strip 44, and the screw will be pushed into aperture 36, as shown in Fig. 5 (not shown). The screws may be urged towards strip 44 by tilting means 16, or compressed air may be introduced into channel 30. In a modification, pusher 38 is cut away at its forward end, and a replaceable plate is screwed to the wall of channel 30, and abuts the recessed face of the pusher, to accommodate shorter screws. Strip 44 may be replaced by a groove or a rebate to allow cone pointed, or headed, screws to be handled. In a further modification, screws which are out of balance about a longitudinal mid-point as opposed to screws which have different end slopes are handled. This is done by providing a platform to which the screws are fed from the hopper; and a sloping block, to which the screw is pushed. At each end of the block is located a feed tube whereby the screws falling off the block are conveyed into a single tube. If the heavier end of the screws is to trail, a means for reversing the screws is provided. The sloping block may be replaced by a platform accurately balanced at its mid-point.
Patent GB-401175-A (GB)
Title: Improvements in and relating to measuring pumps
IPC: C03B27/012
Filed: 1933-03-24
Abstract: 401,175. Measuring-pumps. HEINE, M., 19, Kaiserstrasse, Schwelm, Westphalia, Germany. March 24, 1933, No. 8922. Convention date, March 26, 1932. [Class 102 (i).] The discharge of a measuring-pump for oil &c. or beverages is provided with a byepass which is opened if the pump cylinder is not completely filled with liquid. The piston 30, Fig. 3, of the pump cylinder 13 is driven by links 31 from a gear-wheel 17, which is driven by a pinion and hand crank. The suction and discharge orifice 26 is controlled by a rotating valve 25 which is driven by a pin carried by a disc 22 on the spindle 21. The pin, which engages a slot in the valve, has an eccentric end and the timing of the valve, and consequently the discharge, can be adjusted by rotating the pin by means of a quadrant 48. The valve comprises two semicircular discs connected by a wall 25, and contains a chamber 28 communicating with the suction pipe 12 and a chamber 29 communicating with the discharge 14, under the control of a normally open valve 47, Fig. 6. A lever 55, 61 on the spindle of the valve 47 carries a bowl 56 engaging a cam 60 on the spindle 21. If at the commencement of the discharge stroke the pump cylinder is not full of liquid the bowl 56 enters the recess 85 of the cam 60 and the valve 47 is oscillated, thus putting the discharge of the pump in communication with a byepass passage 38 by means of a groove 91. The liquid, together with trapped air, are thus returned to the suction tank. If, however, the pump cylinder is full, movement of the lever 55, 61 is prevented by a pin 45 carried by a piston 41, which is pressed forward by liquid admitted from the pump cylinder to the cylinder 40 through passages 42, 43. The driving mechanism may sound a bell at the beginning and end of the discharge stroke, or these may be observed through a window 103, Fig. 1, on the counter wheel 100 at the edges of a shield 101. In a modification, Fig. 10, the spindle 115 of the valve 47 carries a lever 118, one arm of which engages the cam 123, while the other arm is acted on by a spring 125, which normally holds the valve 47 in the byepassing position. If at the commencement of the discharge stroke the pump cylinder contains liquid a piston 132 raises a lever 130 on the spindle 115, thus moving the spring 125 over the dead-centre position and permitting the bowl 119 on the lever 118 to enter the recess in the cam 120, so that the valve 47 is turned to discharging position. The pin 45, Fig. 4, may also control the counting mechanism, as shown in Fig. 13. The lever 55, 61 supports a lever 145, 150, which is operated by a pin 148 on the cam 60. When the lever 55 is released by the pin 45 the lever 145 falls to an inoperative position.

Abstract: 1,153,705. Photo-electric control apparatus. BETEILIGUNGS-UND PATENT VERWALTUNGS G.m.b.H. Feb.27, 1967 [Nov.23, 1966], No.9144/67. Heading G1A. The density of material in a jig for classifying particulate material is measured photo-electrically, and only the measurements obtained during that period of a pulsation of the jig when the material is in a tightly packed condition, are used to control the discharge of material from the device. The density is measured using a radio-active source and a detector 7, and signals obtained from detector 7 representative of the density, are fed to a gate 6. A shaft 1, which carries a cam, actuating valves to control the pulsation of the bed of material, has mounted thereon a disc 2 provided with an aperture 9 of partial annular form. A photo-cell 3 is arranged to receive radiation from source 4 when the aperture is in the path of the beam, at which time also the material in the bed is tightly packed. The signals produced are amplified at 5 and used to gate the density measurement signals to the device 8 controlling discharge of material from the jig. At other times, no detector signal from 7 reaches the device 8.

Abstract: 374,982. Vehicle head lamps. LABASTROU, M. L., 40, Rue de Flandre, Paris. March 30, 1931, No. 9615. Convention date, March 31, 1930. [Classes 75 (ii) and 75 (iv).] Reflectors ; lantern screens.-In a vehicle head-lamp in which a real image or images of the source of light is or are formed, the beam of light coming from the-image is defined by means, for instance the apertured front or fronts of one or more hoods, situated substantially in front of the image or images. In the form shown in Fig. 1, the lens 1 brings the light to a focus at 2, and a hood 3 having an aperture 21 extends beyond the image. A divergent lens may be interposed to make the angle of the beam smaller. In a modification, the beam of light coming from the reflector is divided into a plurality of beams by a plurality of lenses or ellipsoidal reflectors, each of which has the light source as one focus. Each lens or reflector has a hood with an aperture arranged as above. In another form, shown in Fig. 3, a series of annular beams of light is formed by a reflector comprising a series of annular reflectors 13 each formed by the rotation, about the axis 11, 12, of an element of an ellipse, having one focus at the light source 11 and the other at a point 14. Cylinders 16 concentric with the axis 11, 12 form the hoods, having annular apertures 15 in front of the images formed at 14. In any of the forms in which a plurality of beams is formed, a single hood having a plurality of apertured screens 19, as in Fig. 6, may be used to define the beam of light. A combination of any of these forms may be made. In the lamp shown in Fig. 7, the lower part of the beam is acted upon as previously described, and the upper half may be screened when desired by a shutter 20 rotatable about a horizontal axis 21, or by a screen movable into a position between the source of light and the reflector. According to the Specification as open to inspection under Sect. 91 (3) (a) in all the forms except that of Fig. 6, the aperture of the cap or hood is situated at the focus, where the image is formed. This subject-matter does not appear in the Specification as accepted.
