Title: Naphtholactam dyestuffs
IPC: C09B57/06
Filed: 1973-05-25
Abstract: 1397174 Naphtholactam dyestuffs BAYER AG 25 May 1973 [26 May 1972] 25140/73 Heading C4P Naphtholactam dyestuffs have the general formula in which A denotes the remaining members of an aromatic ring system, and R denotes H, alkyl, aralkyl, cycloalkyl, aryl or an alkylene radical bonded to the naphthalene ring in the 2- position, and in which the aromatic ring formed by A, and the naphtholactam ring system are optionally substituted. They may be made by cyclization of the compounds and may be converted to quaternary dyestuff salts in suitable cases. They give yellow to red dyes with an intense yellow-green to lemonyellow fluorescence. They are very suitable for dyeing oils, for bulk-dying macromolecular organic materials, e.g. cellulose acetates, polyesters, polyvinylchloride, and for the dyeing and printing of natural and synthetic fibres.

Title: Improvements in or relating to an electrical apparatus for the transmitter of printing telegraphs or like devices
IPC: H04L17/06
Filed: 1937-09-16
Abstract: 499,900. Type - printing telegraphy. UCHIDA, N., UCHIDA, T., and UCHIDA, N. Sept. 16, 1937, No. 25220. Convention date, Sept. 24, 1936. [Class 40 (iii)] A plurality of electromagnets M1 ... M6 are energized in selective combinations by keys Kl ... K5 each operating a single contact J ... J5 respectively. One pole of the operating battery V is connected to all the magnets and the other to all the contacts, and the other side of the contacts is connected to a selection of magnets over leads, each of which contains a unilateral conductor, preventing false operation through return circuits which would otherwise exist through the leads to the unoperated contacts. For example, contact J1 is connected to magnets M1, M4, M6 over leads P1, P2, P3 containing contact rectifiers p1, p2, p3 respectively. When a contact operates a single magnet, or vice versa, the appropriate rectifier, e.g. p1 and q1 may be omitted.

Title: Device for the transportation and temporary storage of prismatic articles and particularly of cigarette boxes between a packing and a wrapping machine
IPC: B65B35/02
Filed: 1974-06-06
Abstract: 1475773 Temporarily strong articles in a conveyer system SKODA OBOROVY PODNIK 6 June 1974 [6 June 1973] 25261/74 Heading B8A A row of articles 2 on a conveyer 5 leading from a packing machine are normally pushed (by a pusher 13 operated by cams 6, 18) into a row 7 of compartments of a vertical endless conveyer 47, and each article is then grasped by respective jaws 25, 26 of a movable holder 24 which then draws all the articles of the row 7 on to a conveyer 39 leading to a wrapping machine. If the latter machine is not operative, a sensor 78 on the conveyer 39 initiates a pulse to a stepping mechanism comprising a ratchet 53 and pawl 63. This causes each row of articles to be lifted step-by-step on the conveyer 47 instead of being drawn on to the conveyer 39. When the wrapping machine recommences, and/or when the packing machine is inoperative, the conveyer 47 is stepped in the downwards direction, and rows of articles 2 are successively drawn out on to the conveyer 39. The various operations are controlled by proximity switches. A switch (76) (Fig. 5, not shown) switches off the packing machine when the number of rows of the conveyer 47 filled with articles 2, reaches a predetermined number. A feeder mechanism (67) checks the presence of articles in the rows of compartments, at the time of their feed-in or withdrawal.

[Class 80 (i).] In an epicyclic friction gear of the kind having an annulus 2 formed with a conical, spherical, or spheroidal bearing surface for engagement by the planetary rollers 4, the pressure on which is thus applied or relieved by axial adjustment of the annulus in an outer casing 3, the casing is provided with several slots or the like 8 through which pass a series of pins 7 fixed to and radiating from the annulus or from a ring 9 rotatable on the exterior of the casing to adjust the position of the annulus axially. Fig. 1 shows the invention applied to the sections 2, 2<a> of a duplex annulus, both having pins 7 passing through longitudinal slots 8 for engagement by rings 9 screwed on the casing 3. The rollers 4 are carried by a spider 5 and engage a sun wheel 6 in the usual way. In a modification, the ring 9 instead of moving axially has a series of cam-like teeth on the edge engaging the pins, the other edge engaging a fixed collar or another set of pins fixed on the casing. In a further modification, the pins which move the annulus are fixed to the outer ring and pass through circumferential slots in the casing into curved or inclined grooves in the annulus, the rotation of which relative to the casing is prevented by other pins engaging longitudinal slots in the casing. The adjusting rings may be locked by set screws.
