Title: Ball joints,especially to be used with motor vehicles
IPC: B62D7/16
Filed: 1967-09-23
Abstract: A ball joint, see Fig. 1, is fitted with a bush 13 of hard, low friction, plastics material, the bush being interposed between the joint pin 2 and an inner side face of a collar 9 and rotatable with the joint pin. At one end, the bush faces the joint housing 1 and it is formed at the other end with a supporting flange 14 against which the end face of a collar lip 16 bears. The lip may be undercut and a clamping ring 10 may be located in the undercut area. To prevent the collar sliding towards the housing a portion of the joint pin is surrounded by a distance sleeve 11. In another embodiment (Fig. 2, not shown), a more efficient seal is achieved by means of annular ribs (18) formed around the outer surface of the bush, snugly engaging in complimentary grooves formed in the inner side surface of the collar. In a further embodiment (Fig. 3, not shown) the bush is formed in one piece with the distance sleeve. In a further embodiment (Fig. 4, not shown) a rib (20) formed on the joint pin is arranged to abut against the inner end faces of the bush and collar to prevent the collar sliding towards the joint housing.

Title: Process for the preparation of caesium metal
IPC: C22B26/10

Title: Method of making metallurgical coke briquettes from coal, raw petroleum coke, inert material and a binder
IPC: C10B53/08
Filed: 1968-04-11
Abstract: Metallurgical coke is made by a two-stage heating process with intermediate pressing and shaping similar to that described in Specification 1,119,869, but the particulate material is mixed with a plasticizing agent which is neither vaporizable nor decomposable below 490 F., e.g. the furfural extract of heavy lubricating oils, asphalt, anthracene oil, coal tar, thermal tar, and pitch (petroleum or coal tar) in amounts of 1 to 8% b.w. of the particulate material. This enables lower temperatures to be employed in the first stage, namely, from 300 F. upwards to one below the fusion temperature of the particles. Fusible coal may be used alone, i.e. without coke, as the particulate material, and the optional inert material includes oxidized raw petroleum coke and ores. The particulate material and the plasticizer may be separately heated before mixing (see Figs. 1 and 2, not shown), or mixed before being heated (see Fig. 3, not shown). Volatile matter contents (by weight) of the particulate materials are: coal alone, 15 to 20% coal with coke, 15 to 45% coke alone (excluding water) 10 to 20% coke with coal, 8 to 20%. Heating in the first stage may be rapid, e.g. 1 second where a coal/coke mix is employed, and carbonization of the shaped bodies is preferably effected within 8 hours. The pressing stage produces a shaped body having an apparent density of at least 0À85 g/c.c. and a porosity not greater than 37%.

Title: Automated audio interrogating and reporting system
IPC: G06Q50/00
Filed: 1973-06-15
Abstract: Described is an automated self-administered audio interrogating and reporting system, for asking questions and printing out responses to the questions, such as in teleconsultation, taking and recording a patient's medical history, or in order-taking, poll-taking, etc. Questions played from a multi-track magnetic audio quesiton tape are responded to at stop intervals by selective actuation of pushbuttons representing multiple-choice answers, such as "YES," "NO," "DON'T KNOW," etc., and a pushbutton titled "REPEAT," for effecting repeating of the preceding question. Branching by track-switching is effected in response to certain answer selections, according to the questions asked by the tape. The answers are represented by audio-frequency tone signals that can command a real-time printout of narrative answer information stored in audio-frequency code form in a dictionary tape, or that may be played back at a subsequent time to effect such printout command. By recording questions on parallel tracks of the question tape between automatically-effected tape stopping points common to all tracks, allowing the answer responses to restart the tape and control any branching-required variation in sequence of questions presented, and by utilizing such answer responses also to restart the dictionary tape between automatic stop points and to control any branching-required variation in sequence of narrative answers, printout of the answers can simply progress on a step-by-step basis between stop points without requiring searching. The answer tape, in addition to storing audio tone codes representing the above-exemplified answers, also stores audio tone codes representing numerical answers by the interogee, as in response to query concerning his social security number, age, zip code, etc., for example, at the start of the history taking procedure.

Patent ES-426149-A1 (ES)
Title: Molding apparatus
IPC: B29C51/10
Filed: 1974-05-09
Abstract: Molding apparatus operating on the fluid pressure forming principle comprises a pressurizable chamber having elevatable vacuum mold structure therein, including a pair of closely spaced unidirectionally presented molds. A clamping ring is positionable to hold a sheet of thermoplastic material over the upper rim of the chamber, in air-tight relation. Means is provided for heating the sheet until it sags slightly, and for introducing heated air under pressure to the chamber to billow the heat-softened sheet upwardly in an amount sufficient to achieve an initial stretch, followed by engagement of the billowed sheet by an assist-plug to urge portions thereof toward the region of adjacency of the unidirectionally presented molds, thereby forming a pair of billowed sections of lesser size. The vacuum molds are elevated into the billowed sheet portions of lesser size, and a vacuum is drawn to the opposite sides of the molds to conform the softened sheet to the latter. Heated pressurized air for billowing is supplied by a combination heater-blower device having a valving system capable of operation either to supply heated air to the chamber, or to halt the supply of air and recirculate same over the heater in anticipation of a billowing operation for an ensuing molding cycle.
