Title: Improvements in or relating to typographical composing and casting machines
IPC: B41B11/06
Filed: 1920-06-22
Abstract: 169,279. Hart, H., (Mergenthaler Linotype Co.). June 22, 1920. Magazines and keyboards for type-bar-making machines. Relates to the connections between the keys and the escapements in machines in which a magazine wider than the keyboard is employed to permit the use of large matrices for advertising or display work, offset connectious being provided between some of the keys and the escapements. The offset connections are in the form of bails, a plurality of which are mounted on a common pivot. The escapements of the magazine, which is made shorter than usual to diminish its weight, are operated in known manner by reeds C<3> from cam-yokes C<4>, which are released by triggers C<6> actuated by slides C<8>. The slides C<8>, corresponding to escapements which are in the same plane as their actuating keys, are connected directly to keylevers C<9>. Where the escapements are offset laterally from their keys, the key-levers operate idle slides C" which are connected to the corresponding slides C<8> by horizontal bails C" which turn on rods C<13> and engage notches in the slides. C<8>, C". The bails are preferably arranged in groups in accordance with the arrangement of the reeds C<3>, the corresponding bails of each group being mounted on the same pivot rod. The bails may be applied elsewhere, for example, between the cam-yokes and the reeds C<3>. Two adjacert channels are allotted to frequently-used matrices, the corresponding escapement-reeds being operated alternately by short intermediate rods D, Fig. 3, which are all connected together and oscillated by a cam which is rotated step by step by the movement of the assembler.

Title: Manufacture of new bis-hydrazones
IPC: C07C281/18
Filed: 1951-07-20
Abstract: The invention comprises bis-hydrazones of aliphatic vicinal dicarbonyl compounds, which hydrazones have in one hydrazone group a guanyl radical, and in the other a phenyl radical which contains one of the following substituents:-  <FORM:0713539/IV (b)/1> These compounds may be prepared by (a) condensing amino guanidine with the monophenyl hydrazone of such a di-carbonyl compound, the phenyl group containing one of the said substituents, or (b) condensing a monoguanyl hydrazone of such a di-carbonyl compound with phenyl hydrazine containing one of the said substituents, or (c) condensing the mono-phenyl hydrazone of an aliphatic vicinal dicarbonyl compound having a group in the phenyl ring, which group can be transformed into one of said substituents, with aminoguanidine, and thereafter transforming said group into one of the said substituents.  In examples (1) pyro-racemic aldehyde-p-guanyl phenylhydrazone hydrochloride is treated with aqueous amino-guanidine nitrate to produce the bis-hydrazone of formula <FORM:0713539/IV (b)/2> (2) using pyro-racemic aldehyde-m-guanyl phenyl hydrazone nitrate the corresponding m-benzamidine derivative is obtained.  Employing diacetyl, pentane 2 : 3-dione, and hexene-(1)-dione-(4 : 5) as the carbonyl component similar products are isolated.  (3) In further examples the phenyl-hydrazone component contains a p-guanidino-; p-guanyl hydrazone formyl-; or a m-guanyl hydrazone formylgroup. (4) Diacetyl-monoguanyl-hydrazone is condensed with p-hydrazinobenzamidine hydrochloride.  (5) Pyroracemic aldehyde p-formyl phenyl hydrazone is condensed with 2 mols. of amino-guanidine nitrate to produce  <FORM:0713539/IV (b)/3> The required starting materials pyroracemic aldehyde m-(and p)-guanyl phenyl hydrazone hydrochloride; diacetyl m-(and p)-guanyl phenyl hydrazone hydrochloride; (pentane-2 : 3-dione-3)- and (hexene - (1) - dione -(4 : 5)-4) - p - guanylphenylhydrazone hydrochloride are prepared by condensing the appropriate aceto acetic acid with diazotized m-(and p)-amino benzamidine which is in turn obtained by reduction of the corresponding nitro benzamidine.  Pyroracemic aldehyde - p - guanidino phenyl hydrazone hydrochloride and the corresponding m-(and p)-(guanyl hydrazone formyl)-phenyl hydrazone hydrochloride are prepared likewise from the requisite acetoacteic acid and diazotized p-amino phenyl guanidine or m-(or p.)-amino benzal guanyl hydrazone (obtainable from the corresponding nitro compounds, or in the case of p-amino benzal guanyl hydrazone by treatment of p-acetamino-benzaldehyde with amino guanidine nitrate). Diacetyl-mono-guanyl-hydrazone is obtained from diacetyl and aminoguanidine carbonate.  Pyro-racemic aldehyde-p-formyl phenyl hydrazone is prepared by coupling diazotized p-amino benzaldehyde with aceto acetic acid.

Title: Improvements in machines with two blades for shearing metals
IPC: B23D15/02
Filed: 1924-07-21
Abstract: 231,722. Gill, H. A., (Maschinenfabrik Sack Ges.). July 21, 1924. Shearing.-The cutters of a shearing-machine are interconnected by a bell-crank so that one cutter first moves into contact with the work after which the other cutter operates to shear. The cutter slide c, Fig. 1, is linked at d to a bellcrank e which is pivoted in the upper cutter-slide b at f. The free end of the bell-crank is driven at g by an eccentric &c. rod h or by the piston rod of a hydraulic cylinder. On movement of the eccentric &c. rod in the direction of the arrow, the lower cutter-slide, in virtue of its superior weight remains stationary till the upper slide descends on to the work, after which the pivot f remains stationary while the lower cutter rises to shear. The bell-crank may be pivoted in the lower cutter-slide. A holding-down shoe u, Fig. 5 is counterbalanced and is linked at r to the bell-crank e so that the work m may be clamped on the lower cutter when the latter ascends to perform the shearing operation. The holding- down rod may be adjustable in length. A gauging stop y for the work may be fitted.

Convention date, July 10, 1934. [Class 16] A memorandum device comprises a shallow box-like member 1 for receiving a pack 10 of folded manifold forms 9, a writing and cover plate 7 hinged at its upper edge to the box 1 and formed with a slot 8 adjacent and parallel to its upper edge through which the manifold forms may be drawn, studs 14 on the plate 7 adjacent the slot, clamping means for removably retaining transfer sheets to the plate, and means on studs 19 at the lower end of the plate for retaining the forms 9 in place on the plate. The transfer sheets, provided at their top edges with reinforcing strips of paper &c. which extend beyond the sheets at either side and are formed with slots, are secured on the plate 7, in interleaved relation with the record forms 9, by engagement of the slots in the reinforcing strips with the studs 14 on the plate 7. The record forms and transfer sheets are guided and held in position respectively by a flexible removable strip 16, formed with slots which engage under the heads of the studs 14. Near the bottom of the plate 7 a second retaining and guiding strip 18 is permanently secured thereto by means of the studs 19. The plate 7 is shorter in length than the length of the record forms, but longer than the length of the transfer sheets, and the end 71 of the plate 7 does not extend to the front wall 4 of the box 1, thereby enabling the bottom edges of the record forms to be grasped. To bring a fresh set 9 of record forms into position on the plate 7, the bottom edges of the record forms are grasped and raised, as shown. The plate 7 is also raised at the same time, due to the strip 18, and thus space is provided for movement of the next set 9 of record forms between the pack 10 and plate 7. The lines of perforations separating the record forms engage the front edge of the slot 8 for aligning purposes. The box 1 is provided with a binding 23 secured on the base thereof, and extended to form a cover 24. The cover 24 may be provided with corner pockets for retaining thereon a record sheet for use with the record forms.
