Title: Obstetrics device for livestock.
IPC: A61D1/08
Filed: 1981-04-14
Abstract: An apparatus is provided for livestock obstetrics. The apparatus bears against the body of the dam, a leg sling is placed on the offspring, and two slides can progressively be moved along a rod to tension the leg sling. To move the slides, a tensioning lever is hinged to one slide, and an intermediate lever is hinged at a different location to the one slide and is also hinged to the other slide. The intermediate lever is in two parts normally held together by spring tension, but if an excess load is applied by the tensioning lever the spring tension is overcome and the parts separate, whereby maximum permissible tension between dam and offspring is not exceeded. To completely release the pull on the offspring, the tensioning lever can be moved to release both slides.

Patent ES-8203715-A1 (ES)
Title: Daisy wheel printers.
IPC: B41J7/34
Filed: 1981-07-07
Abstract: A daisy wheel printer wherein a non-contacting sensor (24) is employed to detect the rotational position of the daisy wheel (10) by response to the interrupting action of the character stalks (12, 14) and to produce a train of pulses providing positional information in accordance with said interrupting action. In accordance with the invention, each stalk of the daisy wheel is divided by a longitudinal slit (26) into two or more branches (28, 20) thereby to increase the frequency of the interrupting action and, for a given rotation of the wheel, to cause the sensor to produce a train of pulses (32) containing a number of pulses which is an integral multiple of the number of stalks passing the sensor.
Patent ES-8301160-A1 (ES)
Title: Double decker goods vehicle
IPC: B62D21/09
Filed: 1981-12-23
Abstract: A goods vehicle, e.g. the trailer of an articulated vehicle, has two loading decks. The upper deck (17) extends over the entire useful length of the vehicle, while the lower deck (15) is disposed at substantially the same height above the ground as the centers of the back wheels (34). The front portion of the lower deck is fitted with refrigerated compartments (18). The low height of the lower deck is achieved by using independent suspension in the form of pivoted arms associated with suspension and damping units. By virtue of the way the lower deck is low slung, it is possible to have two loading decks each with man-sized head-room, and still drive the vehicle under most bridges. The invention is particularly applicable to transporting goods to supermarkets.
Patent ES-8303757-A1 (ES)
Title: Improvements in and relating to testing coins.
IPC: G07D/
Filed: 1982-02-15
Abstract: A coin testing apparatus comprises transmitting and receiving coils (14) and (15) on opposite sides of a coin passageway (11). The transmitting coil is connected to high and low frequency oscillators (16) and (17). The output of the receiving coil is separated into the high and low frequency components by a high pass filter (21) and a band pass filter (22). In the high frequency channel the signal is amplitude controlled by a voltage controlled amplifier (23) rectified by a rectifier (24) and smoothed by a long time-constant circuit (26). The initial rise in level caused by a coin entering between the coils (14) and (15) is detected by an instantaneous level change comparator (32) which responds to the rate of change of signal level at the output of the long time-constant circuit (26) becoming equal to a preset threshold and causes a normally closed switch (27) to be opened. When the switch (27) is closed a comparator (31) compares the signal with a reference value from a source (30) and adjusts the gain of the amplifier (23) until the signal corresponds to the reference value. Upon the arrival of the coin the switch (27) is opened and a long time-constant circuit (28) causes the gain of the amplifier (23) to be maintained at the level before the arrival of the coin. A window comparator (33) compares the difference in voltage with voltage ranges for acceptable coins. A similar arrangement is provided in the low frequency channel but with two differences. The switch (27) in the low frequency channel is operated by the same instantaneous level comparator as is used for the high frequency channel and instead of a rectifier (24) a novel sample and hold technique is used for providing a d.c. signal from the output of the amplifier (23).
