Abstract: 204,574. Fleming, I. R. Sept. 9, 1921. Awnings, special applications of.-In a twopart ayning 2 mounted on arched supports 3 working on guides 4 mounted on the gunwale 5, the entrance of water into the boat is prevented by a strip 12 secured at one edge inside the gunwale, the other edge being provided with hooks which engage with the canvas or arches of the hood.

Port holes 17 with closure flaps 18 are provided in the hood to accommodate the oars when the boat is being rowed.
Patent GB-1013375-A (GB)
Title: Improvements relating to the manufacture of metallic structures with controlled porosity
IPC: B01D39/20
Filed: 1962-06-22
Abstract: In a process of producing a porous metallic body a bonding metal compound is introduced between the grains of a metal or abrasive material, the compound is converted in situ to the metal powder having a grain size less than 100 Angstroms and then sintered at a temperature substantially below the melting point of the bond metal. The bond metal may be Fe, Ni, Co or Cu and is added either as an organo metallic compound such as an aldehydic or ketonic derivative of a higher partially oxidized polyalcohol or sugar derived from the metallic hydrate or chloride or as complex metallic ions e.g. cupro nickel hydroxide in an ammoniacal solution.  A binder such as a carbohydrate solution may also be added.  The metal to be bonded may be added as metal powder or as an oxide, sulphide, or chloride which is reduced to the metal by heating in a reducing atmosphere.  The particle sizes of the powders are chosen to produce a predetermined porosity and in the examples "Monel" (Registered Trade Mark) oxide powder is mixed with a paste of an organo metallic compound of Ni, Cu or constantan, shaped by compaction, extrusion or injection moulding, reduced at 250-300  DEG C. and then sintered up to 320  DEG C.  Fe powder of 300 Angstroms may also be bonded with Cu and "Monel" (Registered Trade Mark) may also be bonded with 70% Cu-30% Ni.

Title: Improvements in and relating to machine knitting
IPC: D04B7/04
Filed: 1919-10-08
Abstract: 162,688. Spence, R. D., and Spence, H. R. Oct. 8, 1919. Parallel machines; knitied fabrics; striping, plating, and making shot ejects. - Plating-thread carriers 1, Fig. 4, are provided with two ducts 3, 4 separated by a rib 5, which causes a vertical displacement of the threads and allows a constant relationship between them during each traverse, thus ensuring perfect plating. When the movement of the carrier 1 is reversed, the position of the threads is also reversed, and a single-course stripe effect is obtained. Another form of thread-carrier, Fig. 7, has two oblique slots 3<a>. 4<a> for the threads, and the under surface 5<a> may be flat or bevelled. When the carrier is travelling in the direction of the arrow the threads take up the positions shown, and when the carrier reverses, the threads move to the opposite ends of the slots 3<a>, 4<a>, thus reversing their positions relative to the needles and producing the single-course stripe effect. When ribbed goods are knitted, the plain needles draw one thread while the rib needles draw the other thread, as shown in Fig. 14. Instead of being fixed, the carrier 1 may be mounted on a swivel or adjustable arm, and may be moved by hand to effect a change in the knitting. The invention is applicable to purl machines, in which case the rib 5 is arranged obliquely between the ducts 3, 4 and has a depression on either side.

Patent GB-1491798-A (GB)
Title: Amplifier arrangement linearised by automatic correction
IPC: H03G3/20
Filed: 1975-06-10
Abstract: 1491798 Amplifiers-correction of distortion LGT LABORATOIRE GENERAL DES TELECOMMUNICATIONS 10 June 1975 [11 June 1974] 24907/75 Headings H3W and H3T To correct distortion arising in an amplifier 3, e.g. the output stage of a transmitter, the output signal 4, attenuated 5 by a factor equal to the nominal gain factor of the amplifier is compared with the signal entering the amplifier, a signal depending on their difference being combined with the input 1 to the stage in a correcting predistorting circuit 2. Due to phase shifts, such a system is limited to a narrow frequency band: for an amplitude modulated transmission, e.g. TV, a wide band correction system may operate on the modulation alone as in Fig. 2. In a correcting predistorting circuit 12 modulated carrier 1 is split by 3 dB coupler 20 into quadrature and in-phase signals, the latter being split again by coupler 22 to enter identical current-controllable attenuators 24, 25. These both produce a small phase shift, matched by phase shifter 28, e.g. a line, on the quadrature signal from coupler 20. The attenuated signals are recombined by coupler 23 and added to the un-attenuated signal from 28 in coupler 21, the unused terminals of this and other couplers being terminated by their characteristic impedances. The two variable attenuators 24, 25 are used to increase power handling; only one need be employed,eliminating couplers 22, 23. The output from predistorting correcting circuit 12 passes via linear pre-amplifier 18 to amplifier 13 having gain G (to small signals): the output signal is reduced by factor 1/G in attenuator 15 and its modulation and that of the amplifier input signal are extracted by detectors 27, 26 and compared in comparator 16. A difference signal including adjustable D.C. bias controls the attenuation in attenuators 24, 25 according to a prescribed law (Fig. 4, not shown). The comparator circuit (Fig. 3, not shown) may comprise a differential amplifier feeding via an adjustable tap across a Zener diode for bias control to a tuned transistor pair in an emphasis circuit to exaggerate the correcting modulation output within a critical band of modulation frequencies, e.g. the colour sub-carrier of a TV signal. Alternatively the attenuators 24, 25 may be frequency dependent, eliminating the need for an emphasis circuit. An alternative arrangement may operate on IF in a transmitter containing an IF stage, the detectors 26, 27 becoming frequency converters HF to IF, the correcting pre-distorting circuit 12 being an adder as at 2 (Fig. I ), and the pre-distorted IF signal entering amplifier 13 via the normal frequency converter IF to HF.

The pulses are formed by a threshold detector responsive to a sawtooth voltage produced by a capacitor, a switch and a controlled current source. The current from the source, and the magnitude of the sawtooth voltage during the existence of the pulses are adjusted by circuits responsive to the input voltage to the converter and to an adjusting voltage which may be derived from the converter output As shown in Fig. 9, a circuit providing a regulated supply voltage Vo and energizing a line deflection coil Ly in a television receiver includes mains terminals 1, 2, a rectifier 3 and smoothing capacitor 4, a switching transistor Tr, inductances T 1 , T 2  formed as transformers, and an output smoothing capacitor 5. A square wave oscillator 8 controls a transistor S in the charging path of a capacitor C so that a sawtooth waveform is supplied to the base of a further transistor Dr operating as a threshold device with a reference voltage V r  applied to its emitter terminal. The transistor Dr is connected through an amplifier and transformer circuit to produce switching signals controlling the markspace ratio of the main coverter element Tr. In order to regulate the output voltage Vo, the operation of the sawtooth circuit is controlled by a resistor network 10, 11, 12, R B1 , R B2 , R r  connected between the smoothed input voltage line V B  and the reference voltage line V r . The latter voltage is formed by comparing the output voltage V o  with a Zener reference voltage 22 in a transistor amplifier 21. A capacitor 23 forms a soft start device, and a thyristor 29 is triggered by an overcurrent sensing circuit 29'. The control arrangement may be used with other forms of converter, Figs. 1, 4, 6, 8, 10 (not shown).
