Title: Improvements in or relating to saddle tractors
Filed: 1951-03-01
Abstract: 694,896. Vehicle fittings for loading. ALUMINIUM CASTINGS CO., Ltd. March 1, 1951. [Oct. 12, 1950] No. 5010/51. Class 78 (iv). [Also in Group XXXI] A compound vehicle comprises a tractor unit, which may be mounted on endless tracks, half tracks or wheels only, and a saddle element which is detachably mounted on the tractor and which can be connected either with the front end of the load itself or with a twowheeled trailer which carries the load. The vehicle is intended primarily for logging, and enables felled logs to be dragged along or cut timber to be towed along on a pair of wheels or on a trailer. The tractor is fitted with a winch to facilitate lifting and coupling up the saddle element on to the tractor. Alternative forms of the tractor are shown in Figs. 1 and 2. In Fig. 1 the endless track is driven from a sprocket 7 and each of the bearing wheels 3, 4, 5 is carried by separately articulated levers 6a, 6b, 6c, all mounted on a single frame 6 articulated to the leaf spring 2. Over the driver's seat is a bracket 13 carrying a jib 16, the winch being driven from the engine. At the rear is one or more ball sockets 12 to receive the saddle element ; if only one socket is provided it may be longitudinally adjustable. As shown in Fig. 2, a front wheel unit 9 may be added to make a half track vehicle. In a further modification, wheels may be bolted to the driven hubs 11 to make a wheeled vehicle, or cable drums may be bolted to the hubs 11. With the latter arrangement the drive to the endless tracks is disconnected and the hubs 11 driven through the normal track driving gear whereby their speeds may be individually controlled. Figs. 4 to 7 show four ways of conveying the load. In Fig. 4 the timber is chained to a support 18 having side stakes 21, and is loaded by the tractor winch so that a ball pivot on the support 18 engages one of the sockets 12 on the tractor, and two rollers 20 on the support 18 engage a circular trackway 19 to give lateral stability. In Fig. 5, the saddle element is in the form of a bracket 25 with ball pivot 26 and platform 28 which is secured to the bracket 25 by hooks and struts 31 and to which is secured the load by chain 32. To the rear end of the load is clamped a trailing axle 33. The bracket 25 is provided with its own band-operated winch 34 to facilitate loading the timber on to the platform 28. In Fig. 6 the saddle element is in the form of a wheeled bracket 36 also provided with its own winch 37 and with a ball pivot 26. In Fig. 8 (not shown) the arrangement is similar to that in Fig. 5 except that a complete trailer with a pair of wheels 30 is provided.

Title: Circuit for generating and modulating carrier waves
IPC: H03C1/52
Filed: 1942-05-01
Abstract: 553,428. Valve generating and modulating circuits. STANDARD TELEPHONES & CABLES, Ltd. May 1, 1942, No. 5891. Convention date, May 3, 1941. [Class 40 (v)] In a combined valve modulator and generator circuit, a piezo-electric crystal functions to stabilize the generator frequency and to suppress the unmodulated carrier. As shown, the crystal 2 has its lower electrode 8 earthed, and its two upper electrodes 7, 9 connected respectively to the plate and to the grid 22 of a valve 20, which generates oscillations at the series-resonant frequency of the crystal. Modulation is applied through a transformer 3 to the inner grid of the valve 20, giving a modulated output through the transformer 6. From this output, the unmodulated carrier is suppressed by the short-circuiting effect of the crystal electrodes 7, 8. One of the sidebands may also be suppressed by a filter 28. The modulated output may be fed through a condenser 26 to a rectifying diode 14. The diode load impedance Z, is high at voice frequencies and as it is included in the circuit of the inner grid, it gives a negative feed-back effect to reduce distortion. An impedance Z 2  between the valve plate and the crystal, and a further network Z 3  between the diode anode 14 and earth, offer high impedance at the carrier and side band frequencies. In a simpler circuit, Fig. 1 (not shown), the diode anode is connected through resistances both to the secondary of the output transformer 6 and to the electrode 9 of the crystal, and the network Z 2  is omitted.

Abstract: 373,632. Valve generating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Feb. 25, 1931, No. 5946. Convention date, March 1, 1930. [Class 40 (v).] In order to stabilize the frequency of a thermionic oscillator, back-coupling energy is taken from parts of the output circuit in which high frequency currents have a phase difference dependent on the frequency, and harmonics of these currents are made to beat with each other to produce the fundamental frequency which is fed back to the grid circuit The anode circuit of the oscillator 8, Fig. 1, comprises two members 1, 2, the parallel circuit 1 being tuned to the fundamental frequency #o while the impedance of 2 is neutralized by the condenser 13. At frequency #o the grid voltages of the frequency multipliers 9, 10 are in phase, but any variation in this fundamental frequency produces a phase difference between these grid voltages. The frequency multiplication of the valves 9, 10 is arranged to produce the fundamental frequency by beating, so that energy of fundamental frequency having a resultant phase displacement n times the original displacement, is fed to the mixing valve 11 and thence back to the grid circuit of 8, where n is the larger frequency multiplication of the two valves 9, 10. The two coupling members 1, 2 may be in parallel instead of series; also, the coupling members may consist of a tuned circuit 1 and low frequency modulating valve 12 as shown in Fig. 2. The two coupling members may be arranged in a common tuned circuit, Fig. 3 (not shown). Known neutralizing arrangements may be used to prevent direct back-coupling in valve 8, or a screened grid valve may be used.

Title: Improvements in platen presses
IPC: B41F1/26
Filed: 1922-03-01
Abstract: 178,080. Rockstroh, M. April 5, 1921, [Convention date]. Platen machines; tripping, throw-out, and like arrangements.-A platen press provided with an automatic sheet-feed and with adjustable eccentrics for connecting the platen to its actuating. mechanism to permit the pressure to be varied, is so constructed that, after the printing operation, the eccentrics are rotated to an invariable " off " position, so that the return stroke of the platen always terminates at the same place and so ensures accurate registry of the sheets. A sliding platen 7 moving on guides 8 is operated by a crank 4 and connecting-rods 5 connected to eccentrics 14 on a platen shaft 6. A ring 9, fitted with grippers 10, 11, 12, feeds the sheets from a feed-board 13, and the platen 7 is, in the normal working of the press, always opened to the position shown in Fig. 2 and remains in this position until after a gripper has seized a sheet. As the platen moves to printing position, the eccentrics 14 are rotated by means of an arm 15, on one of the eccentrics, connected by a link 16 to a bell-crank 18 pivoted to the platen and connected to a link 19 pivoted at 20 to the frame of the machine. The link 16 is adjustable in a concentric slot 23 in the lever 18, and the rotation given to the eccentrics 14, and consequently the printing pressure, depends on the position of adjustment of the link 16. Owing to the curve of the slot 23, the eccentrics 14 are always in the same position when the machine is in the " off " position shown. The invention may be applied to platens having an oscillating or rocking motion, and the machine may be used without the adjustments described for the eccentrics 14, by disengaging the stud 20.
