Title: Drive gear system for motor vehicles
IPC: B60K17/04
Filed: 1974-04-03
Abstract: Drive gear system for motor vehicles. The invention is particularly applicable to driving means such as planetary gearing for connecting multiple electric motors respectively to individual wheels of such vehicle. Recognizing that differing demands are made upon various parts of such mechanism, such as the braking disk, the wheel rim supporting disk and other component parts of the drive system, it is expensive and inconvenient to make the entire unit of material capable of meeting the most severe conditions imposed upon any part thereof. Accordingly, there is here provided a construction by which the braking disk, the wheel rim supporting disk, ring gear, supporting housing and other component parts may all be made as units separate from each other and therefore made as desired of materials appropriate to their respective functions. Further, the braking disk and support structure therefor are excepting for a small centering land mounted in a manner to be spaced from adjacent components whereby to minimize heat transfer and resulting distortion.

Patent ES-439685-A1 (ES)
Title: Phase switching circuit
IPC: H03F3/72
Filed: 1975-07-23
Abstract: A phase switching circuit utilizing a novel bidirectional transistor having a signal applied to its base and a flip-flop circuit arrangement coupled to its output terminals which may be referred to as either collector or emitter depending upon the operation state of the circuit. The flip-flop circuit has a pair of transistors which act as switches and which are respectively coupled in series with the output terminals of the bidirectional transistor. When each of the flip-flop transistors is conducting, a power supply signal is conducted in opposite directions through the bidirectional transistor depending upon which of the transistors is in the on and which is in the off state. Essentially, the switching action of the flip-flop circuit converts the operation of the bidirectional transistor between emitter follower and collector follower configurations, hence the output signal is shifted from a signal which is in phase with the input signal to a signal which is out of phase with that input signal.
Patent ES-443724-A1 (ES)
Title: Continuous molding conveyor with side clamping and release
IPC: B29C48/90
Filed: 1975-12-19
Abstract: Plastic is foamed in a pressure tunnel portion of a molding conveyor formed by opposed endless conveyor runs with side pieces defining the product cross section. One or both employed the endless runs, preferably the bottom conveyor run is laterally split into at least two separate endless shiftable conveyors respectively carrying the side pieces forming the sides of the pressure tunnel, which shiftable conveyors are laterally movable, with respect to the conveying or molding direction, at the tunnel entrance and the tunnel exit for clamping and unclamping respectively, that is for bringing the side pieces horizontally toward each other transverse to the molding direction to form the final configuration for the tunnel cross section and away from each other at the molding tunnel exit to release the sides of the molded product. This clamping and unclamping of the side pieces is particularly important with molded sheets having a configured edge so that the side pieces may be constructed with a corresponding configuration. Preferably, the two shiftable endless conveyors are constructed of a series of plates having pivotal connections therebetween to form a chain, which connections will allow additional sliding or shifting of the plates with respect to each other within a limited range, preferably under the control of guide means on the individual plates and stationary support structure. Preferably, the guide means are rollers on the plates engaging within stationary tracks. A flexible cover endless belt may be employed to bridge the joint between the shiftable endless conveyors and form the entire bottom surface for the tunnel portion. After the lower shiftable conveyors have been moved toward each other to their final tunnel configuration, a flexible endless belt may be tightly brought into contact with the tops of the side pieces and clamped by the upper rigid endless conveyor, so that through the unsupported tunnel portion, the upper belt will be tightly held at its opposite ends and not subject to sagging while forming a smooth continous upper wall for the molding pressure tunnel.
Patent ES-445552-A1 (ES)
Title: Fluid pressure braking system including a pressure differential responsive valve device
IPC: B60T15/36
Filed: 1976-02-26
Abstract: The service and emergency braking system for use on articulated vehicles having service brakes actuated by air pressure and having emergency brakes held in a released condition by air pressure. The system includes valving which is responsive to a pressure differential between the fluid pressure level in the service line connecting the portions of the articulated vehicle and a reference pressure, so that the emergency brake control is vented during a service brake actuation to permit the emergency brakes to effect a brake application when the pressure of the service line drops below the reference pressure by a predetermined amount, thereby providing braking on all portions of the vehicle in an emergency braking situation when the service brake line interconnecting the portions of the vehicle has been broken or has been left disconnected. The reference pressure is generally at the outlet of a regulating valve having an inlet connected to the outlet of the conventional operator-actuated service brake control valve. The regulating valve is provided with valve members between the inlet and outlet thereof which delays fluid communication until the pressure at the inlet attains a predetermined level whereupon the valve opens to permit communication between the inlet and outlet through a flow restricting orifice. Upon release of the brakes, the regulating valve opens to permit substantially uninhibited fluid communication between the inlet and the outlet.
Patent ES-448729-A1 (ES)
Title: Digital multitone generator for telephone dialing
IPC: H04W84/02
Filed: 1976-06-10
Abstract: A digital signal generator that produces multifrequency tones in the voice band range for use in telephone station sets utilizing multitone dialing. Amplitude information describing each of eight voice band frequencies is digitally encoded into a sequence of multi-bit words describing the amplitude at successive data points along the waveform. The eight frequencies so encoded are separated into four upper and four lower frequencies and stored in two solid state read-only memories. Upon command amplitude data words for one upper and one lower frequency are sequentially read out of the memory in time synchronization, added, and their sum applied to a digital delta modulation circuit. The delta modulator determines the change between two successive data word sums and describes the change by an output of either a binary one or a binary zero. The delta modulator output thus comprises a series of binary ones and/or zeros forming an aperiodic digital pulse train which is applied to an output module consisting of an integrating network to synthesize an approximation of a multitone dialing waveform which is compatible with the common carrier telephone network.

Patent ES-456933-A1 (ES)
Title: Silent ratchet
IPC: B25B13/46
Filed: 1977-03-17
Abstract: A ratchet is provided in which a friction brake ring is employed to engage a pawl with the ratchet teeth in an annular ring or hinge extending from a ratchet tool handle. The friction brake ring carries the pawl into engagement when the tool handle is rotated in the direction in which it is desired to turn a workpiece. A spring within the ratchet returns the pawl to a position in which it is disengaged entirely when pressure on the tool handle in the rotational direction of engagement is released. Thus, the return of the tool handle before a subsequent engaging stroke is accomplished silently and without the characteristic clicking of the ratchet teeth of the hinge passing over the pawl.
