Title: Flasher unit for direction indicator lamps - has internal lamp supplied through reed switch surrounded by coil in external lamp circuit
IPC: B60Q1/38
Filed: 1975-04-22
Abstract: The flasher unit for vehicle direction indicator lamps has a bistable mechanical unit (5) operated on by a hot wire (1) to provide an interrupted electrical power supply from the battery (8) to the external indicator lamps (10). The dashboard indicator light (12) receives its electrical supply through a reed switch (13) around which passes a coil (14), carrying current to the main lamps. The configuration of the coil and the low inertia of the reed switch ensure that the dashboard light illuminates when the interrupted current to the lamps reaches a maximum, so that the internal and external lights both flash in unison.

Title: Pressure control valve for hydraulic circuit - with differential piston between pump and reservoir to uncouple pump below maximum reservoir pressure
IPC: B60T15/36
Filed: 1975-04-30
Abstract: The pressure control valve is mounted between the hydraulic pump and the reservoir and regulates the maximum pressure of the reservoir. In order to prevent the pump from running continuously by having the output pressure of the pump the same as the reservoir pressure, and thus preventing the valve from closing, a differential valve element is provided. This has a larger area facing the reservoir pressure and is mounted in a stepped bore. A non-return valve element is incorporated. The arrangement is of use partic. for vehicle brakes.

Title: Air manifold chamber for chilling extruded filaments - esp. polyester filaments produced from several hundred orifices(SF-2.2.76)
Inventor: MURASE YASUHIRO
IPC: D01D5/092
Filed: 1975-06-03
Abstract: A chamber for quenching freshly extruded filaments with forced flow gas streams applied in two complementary flow patterns. One stream of chilled gas is made to impinge in a convergant annular stream on filaments within 5 cm of their leaving the die head. The flow rate of this gas should be 0.1-1 m/s. A second stream of chilled gas is made to converge radially from jets in a cylindrical array around the filament path. The first stream is required to chill the filaments in that zone 'A' to >30 degrees, and 150 degrees C below their melting temperature. The filaments then pass through a zone 'B' pref. 1-5 cm deep which is not force cooled before entering the region 'C' of the secondary cooling jet. Esp. for production of polyester filaments using filament heads producing 500-3000 strands simultaneously and operating at >600 g/mn from each orifice. The chamber provides sufficiently prompt chilling to prevent cohesion between adjacent strands, and sufficiently uniform chilling to produce filaments of similar orientation and diameter when made in relatively large numbers and rapid throughputs.

Title: Suspension for linear eddy current brakes - uses slide guidance to connect brake carrier and bogie frame
IPC: B61H7/08
Filed: 1975-06-18
Abstract: The brake carrier is connected to the bogie frame via a slide guidance. There is a unit to connect the brake carrier positively to the frame, when the brake is not active. When the brakes are active, the unit guides the brake carrier onto abutments, which are rigidly connected to the axle bearings. The brake carrier is connected to a piston rod, of a working cylinder, e.g. a pressurized air cylinder, the housing of which is rigidly fastened to the bogie frame. The cylinder is operated, so that with a pressurized air supply the brake carrier is held on the frame, and is lowered onto the abutments, when the pressurized air is switched-off or fails.

Title: Stimulator for physiological experiments on animals - delivers electrical pulses from rotary interruptor driven by DC motor
IPC: A61N1/36
Filed: 1975-11-06
Abstract: The simple electromechanical stimulator allows physiological experiments to be carried out on the muscles of laboratory animals. It delivers electrical impulses from a series of temporary contacts produced by a rotary interruptor coupled to a direct-current motor. The interruptor creates no inductive effect in the circuit it controls due to the arrangement of the contact pieces. It delivers square-section signals at the output. A regulator can be provided for the speed of the motor driving the interruptor and thus the frequency of the impulses, which can thus be accurately set.

Title: Heat exchanger containing sleeved tube bundles - has inside of tubes and outside of sleeves swept by same fluid
IPC: F28D7/06
Filed: 1976-04-13
Abstract: A tube bundle heat exchanger contains a number of exchange elements, each consisting of a cylindrical sleeve and a bundle of straight tubes inside the sleeve; all the sleeves are connected in parallel to form the complete heat exchanger. The straight tubes of teh bundle inside each cylindrical sleeve are fixed in the end tube plate of the sleeve and are thus in open communication with the end chambers of the main heat exchanger. These tubes thus conduct the first fluid; which also flows in the spaces external to the sleeves of the cylindrical elements. The second fluid flows through the inter-tube spaces inside each sleeve element. The spaces between the sleeves, through which the first fluid flows, are occupied by displacement strips throughout their entire length, so that the heat transfer coefficient in these spaces between the sleeves in the same as the heat transfer coefficient inside the straight tubes, which are traversed by the same first fluid. For cooling or heating water, steam, gas and chemical media and in intermediate superheaters of nuclear power plants. The design is simple and compact and thermal strains are mininial.

Title: Dispositif a effet gunn modulable par impulsions codees, et convertisseur numerique parallele-serie utilisant un tel dispositif
Inventor: GLOANEC MAURICE
IPC: H03K5/04
Filed: 1977-03-25
Abstract: L'invention utilise le fait que, dans une triode Gunn, une impulsion très brève sur la grille provoque la formation d'un domaine dipolaire qui se propage jusqu'a l'anode en un temps de l'ordre de la nanoseconde. Dans le dispositif de l'invention, on ajoute des électrodes ou doigts D1 , D2 , etc., entre grille et anode pour matérialiser des états binaires << 1 >> et << 0 >> par application de potentiels respectivement hauts et bas. Sous chaque doigt porté à un potentiel bas, il se crée une charge d'espace qui produit une impulsion négative dans le courant anodique du dispositif Gunn au moment du passage du domaine dipolaire sous le doigt. A une combinaison d'états binaires simultanés correspond donc une série d'impulsions successives. Application aux convertisseurs << parallèle-série >> en teléphonie par multiplexage temporel.
