Title: Method and apparatus for controlling surface traversing device
IPC: G05D1/02
Filed: 1977-03-25
Abstract: A method and apparatus are provided for controlling the movement of a surface traversing apparatus across a member which has an ordered array of openings in it's surface. Move control routines are provided, each of which instruct the traversing apparatus to move incrementally over the surface of the member by disengaging, incrementally moving, and re-engaging one of two stepping arms. Each routine operates to advance the apparatus an increment in one of a number of directions. Some of the routines move the apparatus parallel to lines or rows of openings. Others move the apparatus diagonally. Each routine senses the relative positioning of the two stepping arms to establish the sequence of operations and returns the stepping arm to its former position if it is unable to complete a step. An automatic selection operation may move the apparatus toward a target opening by comparing the present location of the apparatus with the target address and selecting a routine which minimizes the number of move increments needed to get to the target.

Title: Scraper bar assembly for endless conveyor belts
IPC: B65G45/00
Filed: 1977-10-03
Abstract: A scraper assembly is pivotally supported for biased engagement with the outer surface of a moving conveyor belt to clean the surface of the belt. The scraper assembly includes a plurality of scraper elements spaced along the length of an elongate carrier which extends transversely of the side edges of the belt. Each scraper element is removably mounted on the carrier and at an inclined angle with respect to the direction of movement of the conveyor belt to displace material clinging to the surface of the belt outwardly towards the edges of the conveyor belt. The scraper element consists of a resilient body with a fixedly vulcanized assembly profile with an outwardly open undercut groove for a bolt. The undercut groove extends at an inclined angle towards the scraping edges of the scraper element. The elongate carriers of the carrier device have a curved carrying surface facing the scraper elements. The opening edges of the undercut groove abut against this carrying surface for orientation of the groove parallel with the carriers and thereby for orientation of the scraper elements obliquely with respect to the direction of travel of the conveyor belt.

Title: Leather processing press - with wedges for initial lift and inflatable bag for final pressure of bottom platen
IPC: B30B1/40
Filed: 1978-04-15
Abstract: A hydraulic press is operated in two stages. In the first stage, two wedges which support the bottom platen are moved horizontally towards each other by hydraulic cylinders to lift up the bottom platen with the workpiece against the top platen. In the second stage, a hydraulic device incorporated inside the bottom platen lifts a table with the workpiece against the top platen. Used as press for leather, to smooth and emboss the leather surface during the prepn. of hides for the mfr. of leather articles. This saves a piston/cylinder assembly of large diameter and long stroke. No large and expensive valve for a preliminary filling of hydraulic fluid into the press cylinder is required. The very uniform pressure, applied to the table, results in a lower pressure requirement.

Patent ES-8206321-A1 (ES)
Title: Steering unit for vehicle.
IPC: B60K17/30
Filed: 1981-09-01
Abstract: This invention relates to an improved steering and suspension system for use on off-road type vehicles. The system comprises a gear train at each drive wheel made up of three gears: an input gear, an intermediate gear and an output gear. The input gear is mounted on a driven output shaft which extends out of the differential of the vehicle. The output gear is mounted on an outwardly extending shaft which is retained in a gear case which surrounds the entire gear train. Rotatably attached to this gear case is a tubular hub with a pivotally attached yoke. The yoke supports the axle on which the drive wheel is mounted. Positioned within the area defined by the tubular hub and the yoke are two pairs of intermeshing bevel gears. These bevel gears unite the outwardly extending shaft with the axle and allow torque to be transmitted from the engine of the vehicle to the drive wheels. Also included in this system are two pivotally connected arms which unite the tubular hub to the frame of the vehicle. These two linkage arms cooperate with attached actuating and suspension means to retain the pivot axis of the yoke in an upright position.

Patent ES-8308189-A1 (ES)
Title: Distributed digital conferencing system
IPC: H04Q11/04
Filed: 1982-04-22
Abstract: In time division communication systems one conference technique is to have a processor combine those samples going to a particular station forming a conference having as many subcombinations as there are stations. This approach, while allowing individual station gain adjustment, suffers from its dependence upon a large number of logic operations for a given conference. A modification of this technique is disclosed which uses a distributed structure such that the individual station ports, under local memory and processor control, operate to combine selected time slot samples into a conference sum unique to the station. In this manner gain values may be assigned on an individual listener station basis while the logic processing for the conference is performed in parallel by the ports involved in the conference.

Patent ES-8309044-A1 (ES)
Title: Buffering speech signals in a TASI system.
IPC: H04J3/17
Filed: 1982-10-15
Abstract: A time assignment speech interpolation (TASI) system includes a speech buffer comprising storage packets which are assigned to the individual channels as required for the storage of the signals of each off-hook channel. For each inactive channel, the signals are stored sequentially and cyclically in one packet. When the channel becomes active, the sequential storage of signals continues in this and in further packets as required, signals stored before detection that the channel had become active being retained in the first packet to accommodate the response time of a speech detector of the system. Clipping of speech signals is thereby avoided. The channel is assigned a transmission facility and channel-to-facility assignment information is transmitted, following which the signals of the relevant channel are read sequentially from the buffer packets and transmitted via the facility. Freeze-out of speech signals is reduced because there is a variable delay between storage of signals in the buffer and reading therefrom reading takes place only after a transmission facility has become available and has been assigned to the channel. At the end of each speech burst an end-of-record signal is stored in the buffer following the last signal of the channel this is detected on reading from the buffer to terminate the reading and to indicate that the facility is available for a new assignment. Rapid updating of packets for writing into and reading from the buffer is achieved by assigning, to each channel or facility for which storage or reading is taking place, not only a current packet of the buffer which is currently being used for storage or reading, but also a back-up packet which is the next packet to be used for the storage or reading operation.
