Title: Improvements in sheet printing machines arranged for perfecting
IPC: B65H31/24
Filed: 1928-11-30
Abstract: 302,898. Maschinenfabrik Augsburg- N³rnberg Akt.-Ges. Dec. 22, 1927, [Convention date]. Delivery apparatus.-In an intaglio printing- machine for printing on both sides of sheets, the sheets are delivered alternately to two pile tables r, s, so that those on the table r are arranged with their first-printed sides upwards and those on the table s with the opposite sides upwards. The sheets are taken from the second impression cylinder f by grippers 1 on a delivery cylinder m, and transferred to grippers o on a drying and delivery-cylinder n which is half the size of the cylinder m. After the cylinder n has made one revolution, it either drops the sheet on to tapes p for delivery to the pile r or transfers it to grippers l<1> on the cylinder m which drop it on to tapes q for delivery to the pile s. The tapes p are carried on pulleys t, u mounted on a horizontally-reciprocating carriage and remain stationary relatively to the carriage while moving to the left to receive the sheet z, and then are moved by the pulleys t, u to deposit the sheet on the pile-table r in the ordinary way when the carriage moves to the right. Pulleys v, w mounted on the same carriage as and operated similarly to the pulleys t, u carry the tapes q, which also pass over pulleys x, y mounted in the framing and guides the tapes q so that they do not interfere with the tapes p. The tapes q receive the sheet printed immediately after the sheet x, as the carriage moves to right, and deposit it on the table s on the reverse movement of the carriage.

IPC: F16D66/02
Filed: 1974-08-12
Abstract: 1444508 Disc brakes; indicating brake pad wear NISSAN MOTOR CO Ltd 12 Aug 1974 [28 Aug 1973] 35386/74 Heading F2E A vehicular disc brake has a stationary hydraulic cylinder 12 with pistons 16, 18, the piston 16 acting directly on a pad assembly 22 and the piston 18 acting on an opposite pad assembly 24 via a yoke 34; a torque absorbing structure 42 is integrally formed with the hydraulic cylinder 12 and comprises a pair of leg portions 44, 46 straddling the disc 10 and a pair of leg portions 44a, 46a extending parallel to the face of the disc 10; the leg portions 44, 46 act to guide the pad assemblies 22, 24 in operation of the brake and an elastic means (e.g. the plate spring 64 of Fig. 1) is provided to react against the yoke 34 when the yoke 34 travels towards the brake disc 10 in excess of a preselected distance during operation of the brake as will be brought about by excessive wear of the pad 30 of pad assembly 24. A pair of guide pins 52 passing through holes in the pad assemblies 22, 24 are supported by a bracket 62 rigidly fixed to the yoke 34, and as seen in Fig. 1 the plate spring 64 is rigidly fixed to the bracket 62. Disposed on opposite ends of the plate spring 64 is a pair of spacers 66 and when the yoke 34 travels towards the disc 10 beyond the preselected distance the spacers 66 press against the leg portions 44a, 46a and the plate spring 64 reacts against the yoke 34. This reaction causes the piston 18 to move towards the disc 10, which results in an increase in pedal travel at a master cylinder to warn the driver of wear of the friction pad 30. In the modification of Fig. 3 (not shown) the plate spring is omitted and elastic members (66a) fitted to opposite ends of an elongated bracket (62a) replace the spacers 66. In the embodiment of Figs. 4, 5 a pair of elastic members 80 are fixed within hollows 82 formed in leg portions 44a, 46a and with wear of the pad 30 the elastic members 80 will generate reactive forces against edges 84a of recesses 84 provided in the yoke 34. In the embodiment of Figs. 6, 7, a pair of ring shaped elastic members 90 are carried by rods 92 protruding from the leg portions 44a, 46a and received in openings 98 in surfaces 94 provided on yoke 34. The ring-shaped members can be replaced by elastic sphere or torus members with an opening for the rods 92.

Title: Circuit arrangement for telephone transmission lines
IPC: H04Q3/00
Filed: 1935-12-27
Abstract: 467,987. Automatic exchange systems. STRANDEN, A. E. G. Dec. 27, 1935, No. 35817. [Class 40 (iv)] In arrangements for transmitting calling, impulsing, &c. signals in either direction over two-way junctions including phantom circuits, relays are bridged across each end of a junction and the connections are such that the relays act differentially and are therefore unresponsive both for outgoing signals over the junction and for signals over the phantom circuit. In the system shown, each relay LRAI, LRBI comprises four windings connected in series, resistances rs being added to balance the lines. Signals are transmitted by a directcurrent potential derived from an A.C. source GA through rectifier networks KAI and applied to alternate junction points of the windings of relay LRAI as shown so that the signal current passes differentially through this relay but effectively through all four windings in series of the relay LRBI at the receiving end. The phantom circuit II has similar relays LRAII, LRBII connected to mid-points of relays LRAI, LRAIII, &c. in the side-circuits I, III. A circuit over the mid-points ma, mb of relays LRAII, LRBII in the phantom circuit may be used for the transmission of. alarms, telegraphy, or further telephony. For impulsing, the connection from the network KAI to relay LRAI should preferably include a contact of relay SRAI, and resistances should be included in the corresponding connection at the receiving end. In a modification, each relay LRAI, &c. comprises only three windings, the phantom connection being taken to the junction of the two outer windings which are connected across the line in series, whilst the third winding is normally disconnected but during the transmission of signals is connected to the network KAI which at the same time is connected across the line in series with a choke. In further modifications, the direct current sources at the two ends may be in supporting instead of opposing directions as shown, and additional signals may be transmitted by using potentials of different value or direction and an additional marginal or polarized receiving relay.
