Title: Improvements in mixing chambers of mixing machines
IPC: B01F7/00
Filed: 1967-06-30
Abstract: A chamber for batch mixing of granular, powdered, and liquid materials is of U-shaped cross-section, with a shaft 5 concentric with the curved part of the wall, the shaft having blades 6 throwing the mix into the path of flanged and apertured mixing blades 8. The discharge aperture is in the curved part of the wall, and normally closed by a correspondingly curved door mounted on arms pivoted to the flat end faces of the chamber. The aperture is located so that the rotating blades will tend to push the mix therethrough, the door in its open position acting as a deflector.
Patent ES-344470-A1 (ES)
Title: Master cylinder for brake systems and the like
IPC: B60T11/22
Filed: 1967-08-25
Abstract: A master cylinder for an hydraulic braking system has a cup-gasket 3 on the end of the piston 2 which is directly operable by a pedal and in the released position, is alongside a recessed part 5 of the cylinder wall. Communication between the reservoir 4 and the working chamber 6 is broken as soon as the piston is moved forward, as the lip of the cup is forced into the recess. When the pedal is released, the drop of pressure in chamber 6 causes the lip to contract, restoring communication with the reservoir.
Patent ES-354195-A1 (ES)
Title: System for enriching the fuel mixture on cold starts in an electrically controlled injection system for an internal combustion engine
IPC: F02D41/06
Filed: 1968-05-22
Abstract: In an electronically controlled petrol injection system for an internal combustion engine, having an electromagnetically actuatable fuel injection valve 83 for each cylinder controlled by opening pulses produced by a monostable multi-vibrator 28 in response to triggering pulses from the actuation of cam-operated switches 63, 64, an additional amount of fuel for cold starting is injected by applying additional triggering pulses to the monostable multi-vibrator 28 from an astable multi-vibrator 24 which is set oscillating in response to closingthe engine starter switch 21. The frequency of oscillation of the astable multi-vibrator 24 gradually decreases as the engine warms up, the temperature of the engine being detected by an N.T.C. resister 23 forming a bridge circuit with resistors 58, 46 and 47. When a predetermined temperature is reached, oscillation stops altogether. A normally closed switch 22 is arranged to be opened when a predetermined pressure in the induction pipe or a predetermined engine speed is reached, thereby reducing the magnitude of the pulses transmitted by capacitor 55 to a level which cannot unblock diode 60 so that the astable multi-vibrator 24 cannot then trigger the monostable multi-vibrator 28. Diode 33 protects the circuit against voltage surges from the starter solenoid 73 when the starter switch 21 is switched off. The duration of the opening pulses produced by the monostable multi-vibrator 28 is controlled in dependence on the pressure in the induction pipe by displacement of the iron core 87 of a transformer.
Patent ES-369446-A1 (ES)
Title: Lighting systems for road vehicles
IPC: F21S8/12
Filed: 1969-07-05
Abstract: A shutter 26 reduces the size of a vehicle driver's headlamp beam when light from an oncoming vehicle shines on a photo-cell. The projected beam and the light from the oncoming vehicle pass through a common lens 16. The projected beam is composed of wavelengths to which the photo-cell does not respond. The risk of operation of the system in response to the reflection of the projected beam back into the system is thereby minimised. A dichroic mirror 29 reflects red and infrared light from a white light source 17 while transmitting the remainder to a lens assembly 16 which directs it as a parallel beam for illuminating the road. Light from an oncoming vehicle passes through the lens 16 and the red and infrared components are reflected by the mirror 29 and by a further mirror 28 into a receiver including a photo-cell 21 responsive to red and infrared light. The remaining light from the oncoming vehicle is transmitted by the mirror. The light falling on the photo-cell 21 produces a current which operates a linear actuator 23 to move shutter 26, 27 across apertures 14, 15 respectively. Aperture 15 is always slightly larger and wider than aperture 14 and the shutters 26, 27 will move sufficiently to avoid dazzle. When light is at the extreme end of aperture 15 the aperture 14 can remain fully closed because light still falls on the photo-cell 21 to hold the shutters 26, 27. Other arrangements. Dichroic mirror 29 transmits red and infrared wavelengths while reflecting the remaining wavelengths, the positions of the projector and receiver being inter-changed. Alternatively the reflector 18 of the source 17 is dichroic and transmits red and infrared wavelengths so that light issuing from the aperture 14 is devoid of red and infrared wavelengths. The mirror 29 is then not dichroic but is a conventional half-silvered mirror. The positions of the projector and receiver may be inter-changed.

Each well bottom 22 is flat and lies in a place parallel to said flat surface of the plate. Dimensions of the plate and wells are given. Two examples are given of the use of the slide as a multiple well tissue culture slide.
Patent ES-377648-A1 (ES)
Title: Improvements in tape recorders
IPC: G03B31/06
Filed: 1970-03-18
Abstract: Audio signals and control signals for a slide projector are recorded on the same track of a magnetic tape by means of a tape recorder which subsequently reproduces them through the same magnetic head, the audio signals and the control signals being separated from one another by means of bandpass filter circuits. As shown, during recording the closure of a key 25 energizes a relay 23 which closes contacts c, d to operate the slide-changer of the projector and contacts a, b to cause a filter 9 to pass the fundamental mains frequency from a mains transformer 10 to a record/playback head 8 which also receives the audio input from which the mains frequency component has been removed by a filter 4. In playback, these audio signals (lacking the mains frequency) are reproduced by a loudspeaker 12, while the mains frequency signals pass through a filter 13 to energize the relay 23 which operates the slide-changer as before.

Title: Process for restoring propellent charge powder
IPC: C08J11/08
Filed: 1970-09-04
Abstract: The calorimetric potential of an old propellent charge powder containing nitrocellulose is increased by extracting the powder with methylene chloride.

Patent ES-464453-A1 (ES)
Title: Simplified structure of toy phonograph
IPC: G11B3/00
Filed: 1977-11-24
Abstract: Disclosed is a simplified structure of a toy phonograph in which the output shaft of a motor is selectively put into engagement with the rim of a record disc to drive the latter. A tone arm is provided above the record disc, so that the record disc may be contacted by a stylus carried by the tone arm, when moved axially by the output shaft of the motor brought into driving engagement therewith. The motor is biased for pivotal movement into engagement with the record disc, by means of springs which are retained by terminals of the motor. The springs are made of a conductive and resilient material, for playing a role of lead wire for supplying the motor with power. The springs include a plus side and a minus side springs, one of which is adapted to be separated from the associated motor terminal in the course of the pivotal movement of the motor, to serve as a source switch. The tone arm is normally biased toward the starting point of reproduction, so as to be swung in a space between the record disc and a speaker. When the reproduction is over, the tone arm is displaced radially outwardly or inwardly of the record disc, so as to allow the axial movement of the record disc. During this axial movement the spring comes to be separated by the associated motor terminal to open the source circuit. As a manual switch is depressed, the record disc is lowered to allow the tone arm to return the central starting point of reproduction, and the spring which has been disconnected from the motor terminal is again brought into contact with the latter.
