Title: Improvements relating to the production of unsaturated alcohols
Filed: 1943-03-12
Abstract: The process of the parent Specification for forming unsaturated primary alcohols and esters thereof by reacting, without the addition of catalysts, unsaturated metallic carboxylates with hydrogen under pressure is modified to increase the proportionate yield of alcohols by using a carboxylate of cadmium with that of chromium or of nickel or of copper substantially in the p  proportions of cadmium to chromium carboxylates of 75 : 25, cadmium to nickel carboxylates of 50 : 50 or cadmium to copper carboxylates of 99-50 : 1-50.  Soaps of the specified metals and unsaturated fatty acids of vegetable, animal and marine fats and oils may be treated.  Temperatures are preferably about 240-400 DEG  C. and pressures above 2000 p.s.i.  In an example, commercial oleic acid or "red oil" sodium soaps are converted to cadmium and chromium oleates by double decomposition, and a mixture thereof in the ratio of 75 : 25 heated to 340 DEG  C. under a hydrogen pressure of 350 p.s.i. for 3 hrs.  Mixtures of cadmium and nickel oleates in the ratio of 50 : 50, and of cadmium and copper oleates in the ratio of 97.5 : 2.5 are similarly hydrogenated at a pressure of 4000 p.s.i. for 1 hr.  Other mixtures for which data is given contain cadmium and copper oleates in the ratios 50 : 50, 90 : 1 and 99 : 1.  The Specification as open to inspection under Sect. 91 comprises the treatment of both saturated and unsaturated carboxylates of the specified metals and is not limited as to the proportions in the mixture.  Other mixtures specified are cadmium and chromium oleates in the ratio 50 : 50, and cadmium to nickel oleates in the ratio 90 : 10.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to an intermediate hitch for grain drills
IPC: A01C7/20
Filed: 1946-02-08
Abstract: 608,884. Hitch for agricultural implements. FERGUSON, Inc., H. Feb. 8, 1946, No. 4070. Convention date, March 8, 1945. [Class 6(i)] Intermediate hitch means for connecting a grain drill or like implement with poweroperated hitch means on a tractor, has a connection with the raisable parts of the implement operated by vertical movement of the tractor hitches without causing vertical movement of the connection between the intermediate hitch and the draft member of the implement. As shown, the hitch, comprising coupling members 26 and a crosspiece 27 having a pair of upstanding arms 28 mounted thereon, is fixed to a tractor having lower draft links 18 which can be raised or lowered by crank arms 21 controlled by a hydraulic mechanism as in Specification 470,069 embodied in the transmission case. The other end of the coupling member 26 is connected to the draft member of a seed drill which comprises a wheeled frame on which is mounted a shaft 5 having a plurality of levers 12 connected through rods 14 to discs 10a and seed funnels 11 which are themselves hingedly connected to the frame by members 8. Also mounted on shaft 5 are levers 6 to which are connected springs 7 anchored to the frame and members 17 which converge and straddle part of the implement tongue 16a. The members 17 are used to actuate the implement and are connected to a depending arm 29 of the hitch by means of a chain 36. Vertical movement of the draft links 18 causes the hitch to move relative to the implement tongue about a universal connection 30, without vertical movement of the implement tongue 16a thereby swinging the arm 29 forwardly and turning the shaft 5 clockwise against the action of the spring 7 to lower the disc 10a. and seed funnel 11 into their ground-engaging position. The ends of members 17 are provided with a pin 37 which slides on top of the tongue 16a and is engaged by the teeth of a pivoted latch 39 which is operated by a cord or chain 40. When the implement is at the desired depth and the pin 37 is engaged in the latch 39, the links 18 are lowered. To lift the discs and funnels clear of the ground, the cord 40 is operateed thus lifting the latch 39 and allowing the spring 7 to turn the shaft 5 in an anti-clockwise direction. The arm 28 of the coupling is connected to an upper link 23 on the tractor which is adjustable at 24 thus varying the vertical position of the implement tongue. By mounting the lever 6 on the top of shaft 5 the spring can be used to lower the discs and funnels, the hitch then performing the lifting operation.

Title: Speed control system for hall effect motors
IPC: H02P6/06
Filed: 1970-01-28
Abstract: 1275715 Speed control of electric motors THOMSON - CSF 28 Jan 1970 [11 Feb 1969] 4193/70 Heading G3R To control the speed of a Hall effect motor the field current of the motor is cut off when the motor speed exceeds a predetermined value. The motor comprises a resolver element 1 Fig. 1, and a motor element 2. The resolver stator carries Hall generators 11, 12 and has a permanent magnet rotor 13 coupled to a permanent magnet rotor of the motor. The motor stator has field windings 21, 22. Sine wave output voltages K sin # + K cos 6 respectively from the Hall generators are synchronized with and control the frequency of square wave generators 31, 32 which supply square wave alternating current to the motor field, having a frequency proportional to motor speed and amplitude independent of the motor speed. For speed regulation a comparator 40, Fig.2, compares a signal 42, which is a function of the output frequency of square wave generator 32 and thus of the actual motor speed; with a reference signal 43 representing the desired motor speed and defining a threshold frequency. When the square wave frequency exceeds the threshold frequency the comparator output opens transistor switches 51, 52 cutting off the motor field current. As illustrated in Fig. 4 (not shown) the two outputs from a Hall generator may be coupled to a differential high gain amplifier the output of which controls a transistor switching bridge across a diagonal of which a respective field coil of the motor is connected whereby current from a D.C. source is fed in opposite directions alternately through the coil. In addition the amplifier output is fed to the comparator, which produces an output to block all the switching transistors when the motor speed exceeds the threshold speed. The comparator may include a frequency/ voltage converter and compare two voltages, Fig. 5 (not shown), the reference signal being set up on a potentiometer, or it may compare two frequencies. The system may also include a phase comparator, Fig.7 (not shown) whereby the motor rotor position may be locked to a reference position.
