Title: New or improved process for the preparation of chemical substances to be taken internally by a patient before radiographic examination
IPC: A61K49/04
Filed: 1924-06-23
Abstract: For use in radiography, a heavy metal salt opaque to X-rays is obtained in a state of fine division by reacting upon a compound of the metal with a soluble non-poisonous salt in excess in the presence of gelatine, this salt precipitating the desired metal salt but not precipitating the gelatine.  Excess of the soluble salt is removed by washing.  In the example, a solution of barium chloride is slowly added to a solution of ammonium sulphate in the presence of gelatine. The mixture is stirred for about fifteen minutes and the temperature maintained at about 110 DEG  F.  The ammonium sulphate is always in excess, but a small quantity of sulphuric acid may be added to the mixture as a safeguard.  When the emulsion is finished, additional gelatine is added to ensure setting and to smooth off the emulsion. The jelly when set is divided into shreds, washed, and quickly dried. The final product is in the form of blocks, flakes or powder.ALSO:A process for the production of a preparation to be taken internally by a patient before radiographic examination comprises an emulsification stage in which a heavy metal salt opaque to X-rays is emulsified with gelatine under determined conditions of agitation and stirring, the said metal salt being in an exceedingly fine state of division and becoming uniformly distributed throughout the emulsion.  The fine state of division is attained by reacting upon a compound of the metal with a soluble non-poisonous salt in excess in the presence of gelatine, this salt having a capacity for precipitating the desired metal salt and an incapacity for precipitating the gelatine.  Excess of the soluble salt is removed by washing and the resulting gelatinous mass containing the heavy metal salt constitutes a product adapted for administration with ordinary food.  In the example given, a solution of barium chloride is slowly added to a solution of ammonium sulphate in the presence of gelatine.  The mixture is stirred for about fifteen minutes and the temperature maintained at about 110 DEG  F.  The ammonium sulphate is always in excess but a small quantity of sulphuric acid may be added to the mixture as a safeguard.  When the emulsion is finished, additional gelatine is added to ensure setting and to smooth off the emulsion.  The jelly when set is divided into shreds, washed, and quickly dried.  The final product is in the form of blocks, flakes or powder.  The product may be administered to a patient in the form of a jelly, blanc mange &c.

Abstract: 802,405. Typewriters &c. TRIUMPH WERKE, NURNBERG A. G. May 17, 1956 [May 17, 1955], No. 15353/56. Class 100(4) An electrically operated typewriting, accounting or like machine comprises a number of type-levers with independently operable electromagnets 9 which, upon the operation of a trip member C, are serially operated to effect printing of e.g. a date or number of an account page, in accordance with a manual setting decive S. The trip member C may comprise a pair of contacts which operate by the spacing movement of the machine carriage 12, or, alternatively, the trip member may be a tabulator key B connectible by way of a change-over contact dependent upon the carriage movement. When the trip member C is operated, relay D, Fig. 2, energizes, this operates a relay E which in turn energizes a relay F. Relay F is a stepping magnet whidh shifts a wiper W2 and by means of a circuit 14, F2, W2, and the setting device S, the first electromagnet G is operated. As soon as F relay has operated, relay E is released which, in turn releases relay F, but, since this relay is stepped one place, wiper W1 is connected to earth 14 and relays D, E and F operate again. This action continues until the required date or combination of type operations is complete. As shown any of ten numeral mechanisms G0-G9, can print in four spaces I, II, III, IV to represent the tens and units digits of the day and month, but if necessary letter type mechanisms may be operated. When a tabulator key B is used as the trip member, a magnet (H, Fig. 2a, not shown) normally effecting a tabulation is cut off by the change-over contacts (C<1>) and a relay similar to relay E is connected in circuit to effect automatic typing.

Title: Improvements in machines for horseshoe manufacture
IPC: B21K15/02
Filed: 1923-06-15
Abstract: 215,612. Farrer, J. H. June 15, 1023. Horseshoes are made from blanks which are cut off and fed to an eccentric-operated fullering head and then transferred to a table which forces them between bending-rollers and holds them below an eccentric finishing-head, the transferring-means and table being operated by the first and second head respectively. Merchant bars are heated in a furnace 191, Fig. 28, and discharged successively to spring rollers 204 and a roller 205, intermittently rotated by ratchet and skew gearing 213, 220 and a variable-throw crank 216. The bar thus fed is cut into desired lengths by a blade 230 reciprocated by an eccentric 223 which, with the gear 220, is feathered on a shaft 9. The frame 195 is adjustable on its base 194 by a screw 196 and has a yoke 226 to move the eccentric 223 and gear 220 with it. The blanks are received on a yielding bed 232 and then pushed over a bar 238 and roller 239, so spaced that short lengths overbalance and fall through. Each blank is received on a table 71, Fig. 16 having adjustable guides 77, 78,. spring guides 86, a stop 77<a>, and an adjustable die 73 for the clip. The blank is then clamped by a spring plate 60, Fig. 9, and operated on by fullering-dies 63 and a spreading-die 67 carried by the eccentric-operated head 65. A clipping- die 56, sliding in the head 65 and operated by an eccentric 50, then acts on the metal spread by the die 67. As the head 65 returns rollers 109, Fig. 2, carried thereby, operate levers 103 and pivot arms 105 to carry the blank past the guides 86, down a curved shoot 88 to a table, 159 which is reciprocated by a lever 153, slide 149, sliding cams 144 and link 142 from an eccentric-operated head 113. A former 164, Fig. 24, carried by the table engages the centre of the blank and forces it between bending-rollers 170, Fig. 25, which are moved by springs 174 and cams 165 engaging bowls 171, to bend the blank around the former 164. When the head 113 nears the bottom of its stroke the table 159 is arrested directly under its die 127, Fig. 23, which finishes the horseshoe except for the nail hole punching. When the head 113 rises an adjustable stop 132 actuates an ejector 130 and the shoe is caught by a spring raised hook 137 which is engaged by the head at the next stroke to discharge the shoe clear of the machine. The whole machine is driven by the gearing shown and an electric motor 25 through a clutch member 22, Fig. 3 expanded by a right and left handed screw 31 which is rotated by an adjustably mounted arm 33, feathered sleeve 39, and hand lever 42. When the sleeve 39 is moved in the opposite direction it engages a fixed brake member 41 to stop the machine. The motor is driven through an automatic circuit breaker so arranged that when the load is too heavy the lever 42 is also reversed by an electric magnet.
