Filed: 1966-09-09
Abstract: Apparatus for corrugating previously machined sets of fins on sectors of tubular elements, e.g. sheaths for nuclear fuel elements, comprises a series of blades relatively disposed to form a stack and each blade having one end in the form of a punch of tapered section and whose faces are corrugated, said punch being engageable in the space separating two fins to be corrugated under the action of a member acting on the end of the blades remote from said punch-form ends, said member being displaced parallel to the axis of the series of blades. Previously machined fins 2 of a tubular element 1 are corrugated by tapered blades 9, having their two major surfaces corrugated, driven into the spaces 3 between the fins 2 by a cam 6 moved axially of the element 1. In another embodiment, Fig. 3, (not shown), the blades are driven in and retracted by a cam member moved through, and in engagement with, apertures in the blades. Several such arrangements may be positioned around the tubular element to act simultaneously on fins on different sectors of the element.

Patent ES-358240-A1 (ES)
Title: Typebar drive including reciprocating linear moving cyclic means
IPC: B41J7/94
Filed: 1968-09-17
Abstract: Power operated lever machines.-A power operated typewriter comprises type levers 22 connected to actuator members 15 by connecting links 21, each actuating member being selectively engageable with a reciprocable bail 28 by means of a corresponding key lever 11. Depression of a key 14 acts to urge an actuator member 15 leftwardly, a resilient finger 44 thereby being disengaged from a latching surface 43 on the actuator member, enabling the finger to lift a bail 46 which acts through a lever 47 to initiate engagement of a half-revolution clutch 48, so connecting the drive from a motor 50 to a drive shaft 34. A pair of cams 34 are thereby rotated, lifting the bail 28 to effect an impression. Key interlocks.-Simultaneous actuation of two or more type levers is prevented by a ball interlock 40 which will receive only one tail 38 of an actuator member 15. If a second key is depressed during the cycle of operation of a first key, the corresponding actuator member 15 travels far enough to release the finger 44 so that the clutch 48 remains engaged for a further half revolution to permit a corresponding impression action. Impact adjustment.-The actuator member 15 is driven by the bail 28 for a first part of its pivotal motion after which a projection 55 thereof strikes a rod 56 and the momentum of the actuator member and type lever carry them to effect impression. During the second part of the motion of the member 15, a tab 18 thereof engages the finger 44 which thereby controls the impact. Collective adjustment of the impact is effected by adjustment of the fulcrum of the fingers 44 by movement of a rod (61), Fig. 2, not shown. Letter-by-letter adjustment is achieved by screws 58, 59 which are selectively brought into operative position according to the case shift position. Rebound preventing.-The momentum of an actuator member 15 after impression is absorbed by a resilient finger (67, Fig. 2) which engages a surface 68 of the actuator member. Repeat power action preventing.-If the key lever is still depressed when the actuator member 15 returns after an impression action, the tab 18 strikes a camming surface 74 of the key lever and displaces the key lever out of operative position to prevent repeat action.

Title: Control system and actuator used therein
IPC: F03G7/06
Filed: 1968-12-14
Abstract: The rate of flow of a fluid through a conduit 40, Fig. 1 is controlled in accordance with the temperature of the fluid, measured by a thermistor 42, utilising a thermal actuator 10 to adjust a valve 12 in the conduit. The actuator comprises a sealed cylindrical housing 14 filled with a thermally expandable material 26, e. g. silicone rubber, and a spring-loaded piston 24 whose extension rod 34 adjusts the valve 12. The temperature of the material 26 is determined by a heater 58, embedded in the material, fed with current by control circuit 44 in accordance with the difference between the temperatures of the fluid and the material 26. The material of heater 58 has a low, positive temperature coefficient of resistance which rises very steeply at a critical temperature and prevents overheating. In modifications, the heater 58 may be mounted outside the cylinder 14, or may comprise a carbon black polymer incorporated in the thermally expandable material.

Title: Single print element print carrier with self-contained selection function
IPC: B41J7/50
Filed: 1974-06-26
Abstract: A carrier for a printer, having a single type element, is disclosed. The selection apparatus contained within the carrier is one whereby only a rotary power force plus control signals need be introduced into the carrier. The selection apparatus is comprised of barrel cams having a plurality of channels formed into the periphery of the barrel cams to cause lateral displacement thereof on their drive shaft. The lateral displacement of the barrel cams is converted into a linear motion which is in turn transmitted and converted into rotary motion to position the type element about its rotate and tilt axes. The controls for transmitting signals to the carrier are pneumatic and the pneumatic impulses received by the carrier logic block and actuator blocks activate mechanical latches to insert selector pins into the grooves of the barrel cams. A dual rack and single pinion arrangement is disclosed to convert the linear motion to rotary motion of the type element.
Patent ES-429381-A1 (ES)
Title: Low noise rf signal generator
IPC: H03B1/00
Filed: 1974-08-19
Abstract: A signal generator for generating a high power low noise RF signal is disclosed. The generator includes a low noise crystal control oscillator for generating a relatively low power, low noise RF signal. The output signal of the oscillator is coupled to a high power RF amplifier which amplifies this signal to generate the low noise high power RF signal. The low frequency noise of the oscillator is reduced by a low frequency negative feedback loop in the oscillator circuit. Noise induced into the oscillator circuit by load changes in the power amplifier is reduced by designing the amplifier such that its input impedance is substantially constant for all phase angles of the RF signal.

Title: Apparatus for cooling newly formed glass containers
IPC: C03B9/453
Filed: 1977-09-09
Abstract: In the cooling of newly formed glass containers, the containers are moved from blow molds and placed on what is termed a cooling "dead plate". The dead plate is supplied with air under pressure which is fed into the casting forming the dead plate. The ware sits on a generally flat, perforate member which is the cover for the dead plate casting. The air supply is found beneath the conveyor belt in the housing for supporting the conveyor for carrying the ware away from the forming machine. A plurality of openings, adjacent each ware forming position, are provided through the bottom of the conveyor housing and air within the housing will enter the underlying, horizontal leg of the dead plate casting whose upper surface has complementary openings to those in the conveyor housing and exit through the perforations in the dead plate to cool the ware sitting thereon. A honeycomb structure is provided in the air flow passages from the conveyor connection and also in the passage beneath the dead plate surface to effectively deaden the noise of air used for cooling the ware.
