Title: Phenoxy-phenoxy-alkanecarboxylic acid derivatives
IPC: C07C239/00
Filed: 1977-07-20
Abstract: The herbicide contains, as active substance, novel 3-phenoxy- alpha -phenoxyalkanecarboxylic acid derivatives of the formula I < IMAGE > in which the substituents R1, R2, R3, R4 and R5 have the meanings defined in Patent Claim 1.

Title: Seed planting method for cereal grains and grasses
IPC: A01B49/06
Filed: 1977-10-29
Abstract: A method for planting seeds in a pattern comprising longitudinal and transverse rows of seed planting sites, in which the transverse rows cross the longitudinal rows, the improvement comprising: planting the seeds with a seed-to-seed spacing of 1 to 31/2 inches along both the longitudinal and transverse rows, preferably in an approximately square, equidistant pattern.

Patent ES-8303684-A1 (ES)
Title: Co-ordinate measuring systems.
IPC: G01B21/00
Filed: 1982-03-11
Abstract: A co-ordinate measuring system for determining the relative measurements of an object is disclosed. The system utilizes a probe which has a plurality of faces which are interconnected so as to form two parallel "X" co-ordinate probe surfaces (12) and two parallel "Y" co-ordinate probe surfaces (14).

In this manner, measurements along the "X" and "Y" co-ordinates can be made and recorded at the instant the probe contacts the respective surfaces. An automatic unlatching feature is provided wherein the probe must be a predetermined distance from both the "X" and "Y" surfaces before the system automatically resets.
Patent ES-8304728-A1 (ES)
Title: Phase locked loop tuning system including a prescaler conditioned to oscillate at an out-of-band frequency
IPC: H04B1/10
Filed: 1982-05-28
Abstract: In a phase locked loop tuning system including a prescaler for dividing the frequency of the local oscillator signal by a factor selected to make the resultant frequency divided signal compatible with digital processing portions of the tuning system, a frequency selective network is coupled to the prescaler to tune the self-oscillation frequency of the prescaler to a frequency not corresponding to the local oscillator frequency of any legitimate channel. In this manner, when a new channel is selected and the amplitude of the local oscillator signal is below the threshold at which the prescaler will respond to it, the phase locked loop will properly control the local oscillator, rather than respond to a self-oscillation signal which may otherwise correspond to the local oscillator frequency for the selected channel.

Patent ES-8402463-A1 (ES)
Title: Electron sources and equipment having electron sources
IPC: H01J1/308
Filed: 1982-11-04
Abstract: An electron source having a rapid response time comprises at least one n-p-n structure (and possibly an array of said n-p-n structure) formed in a silicon or other semiconductor body (10) by a p-type first region (1) between n-type second and third regions (2 and 3). Electrons (24) are generated in the n-p-n structure (2,1,3) for emission into free space (20) from a surface area (4) of the body (10) after flowing from the second region (2) through the first and third regions (1 and 3). The n-p-n structure (2,1,3) has electrode connections (12 and 13) only to the n-type second and third regions (2 and 3). The first region (1) provides a barrier region restricting the flow of electrons from the second region (2) to the third region (3) until a potential difference (V) is applied between the electrode connections (12 and 13) to bias the third region (3) positive with respect to the second region (2) and to establish a supply of hot electrons (24) injected into the third region (3) with sufficient energy to overcome the potential barrier present between the surface area (4) and free space (20). The barrier region (1) forms depletion layers with both the n-type second and third regions (2 and b 3) and is depleted of holes by the merging together of these depletion layers at least when the potential difference (V) is applied to establish said supply of hot electrons (24). The n-p-n structure can be provided in a mesa portion (9) of the body (10) at a window in an insulating layer (11) so as to form a compact arrangement having very low associated capacitances. The electron sources may be used in cathode-ray tubes, display devices and even electron lithography equipment.
