Title: Ridge plough for seed drill or planting machine - consists of two V:shaped pivot mounted discs on outside of which rotate roller wheels
IPC: A01C5/06
Filed: 1970-02-11
Abstract: The ridge plough for seed drills and planting machines consists of two V-shaped, pivot mounted discs (18, 20). On the outer circumference of the discs (18, 20) in a staggered position in relation to the centre axis of the discs, rotates roller wheels (10, 22). The roller wheels (10, 22) protrude beyond the back of the discs (18, 20) in relation to the direction of travel. The underneath parts of the roller wheels (10, 22) are directly situated near the point at which the discs (18, 20) emerge from the soil. The roller wheels (10, 22) are mounted in slanting, elongated holes which are made in attachments (14, 26) independent of the discs (18, 20).

Title: Carrier regeneration circuit for multiplex signals - uses simplified four-phase modulation with phase locked loop and has doubler circuit
IPC: H04L27/227
Filed: 1970-10-14
Abstract: The input signal (1) passes through a doubler circuit (25) and is converted to a double-phase-modulated signal and processed by the remodulation loop. The carrier is frequency -doubled in the process and a divider (26) halves it so that the correct carrier frequency is regenerated and appears at the output (27). The processing loop comprises a demodulator (2) with an input connected to a phase-shift network (3). A phase-locked loop is formed from a phase-detector (7), low-pass filter (8) and voltage-controlled oscillator (4) the output of which controls the phase networks. The demodulated signal passes through a limiter (5) which produces a control signal for the modulator (6) where the input signal is again modulated.

Title: Gear making and testing machine - has table and rotary gear support with coupling altering ratio between movements
IPC: B23F5/08
Filed: 1972-02-08
Abstract: The machine for making and testing involute spur gears causes a gear workpiece to wove relative to a tooth forming tool or a testing tracer with both a rectilinear movement and a rotary movement. A table movable rectilinearly carries a rotary workpiece support with the table and support being coupled for interdependent movement. A member moveable transversely on the table is coupled to the workpiece to rotate the support. A slide is coupled to the member and works in a guide rotatable to various angles inclined to the direction of table movement. A drive movable with the guide moves the slide to drive the member and so the support.

Title: Switch protector with magnetic extinguisher - uses permanent magnets with control circuit delaying till passage through zero
IPC: H01H9/56
Filed: 1972-06-30
Abstract: Switch protector has permanent magnets for magnetically extinguishing the contact arc, which can be used both for direct current and alternating current operations. The moving contacts are controlled via a switching system which produces a given delay in the excitation to regulate the instant of switching to the time when the voltage or current is passing through zero. The movement of the contacts will occur within half a cycle and will produce the right polarity with respect to the permanent magnet before the passage through zero before the end of the half wave. The signal generated by the control circuit is different for the switching on and the switching off processes.

Abstract: PURPOSE:To obtain a lead frame which is inexpensive and excellent in assembling workability by providing a plating solder layer partially on the surface of a base body whereon a layer of Ni or an Ni alloy or a layer of Co or a Co alloy is formed. CONSTITUTION:An Ni-P alloy plated layer 4 is formed on the tab 2 of a base body 1 made of an Fe-42% Ni alloy and a lead terminal 3. Furthermore, the plating solder layer 5 containing Pb of 95% is laid on the tab 2, and after a heated semiconductor element 6 is pressed thereon, a wire connection 7 of the element 6 with the lead terminal 3 is conducted. It is desirable that the plating solder layer 5 has a composition containing Pb of 80-98%, since the element is cracked frequently by a heat shock in a cycle of 150 deg.C and -50 deg.C when the content of Pb is less than 80%. when it is above 98%, the heat connectivity is reduced. The alloy layer may be formed on the whole surface or in a part thereof. This constitution enables preparation of the lead frame which is inexpensive, whereby the assembling workability is improved remarkably and which enables attainment of a highly reliable device.
