Title: Improvements relating to electrical controllers
IPC: H01H19/24
Filed: 1921-06-16
Abstract: 166,518. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Meyer, H. R.). July 15, 1920, [Convention date]. Drum controllers.-Between the contact-drum and the operator's handle there is a yielding coupling carrying relatively movable auxiliary contact-members adapted to come together during the initial forward movement and to separate when the handle is moved back. The effect is to ensure a definite order of making the control circuits and remaking them from the start after being interrupted. The construction described, which resembles apparatus of like function described in Specification 163,298, comprises a handle shaft 10 separate from the contact-drum shaft 17 and carrying a disc 12 fitted with prongs 30, 31 adapted to engage similar prongs 36, 37 fitted on a disc 16 attached to the drum shaft. when the handle is initially moved forward, the prongs are brought from the relative position shown in Fig. 5 to that shown in Fig. 6. with compression of connecting springs 44, 45. During this take-up movement, a contact-segment 29 mounted on the disc 12 comes on a stationary finger 52, Fig. 7 and a movable finger 47 attached to 29 comes on a conducting face of the disc 16, so as to prepare for energizing a main switch operating solenoid 38. Further movement of the handle carries the controller drum forward and completes the circuit of the solenoid, afterwards shortcircuiting resistances as usual. If the handle is let go or turned back, the springs 44, 45 return the discs 12 and 16 to their original relative positions and break the circuit of the solenoid, which cannot be re-energized until the preceding sequence of operations has been retraced.

Title: Improvements in processes for reducing photo-chemical damage to super polyamides andpolyurethanes
IPC: C08K3/11
Filed: 1952-07-03
Abstract: Photochemical damage to polyamides or polyurethanes is reduced by adding a chromium salt to the monomeric starting materials and polymerizing in presence of the salt.  The amount of chromium salt added preferably varies from .01-.1 per cent.  The polymerization process and subsequent yarn-spinning and stretching processes are not adversely affected.  Water-soluble salts, e.g. chromic fluoride may be added to aqueous solutions or melts of the polymer-forming ingredients.  When water is undesirable, e.g. in a reaction between a di-isocyanate and a glycol, the chromium salt, e.g of an organic acid may be dissolved in one component of the reaction mixture, e.g. the glycol.  If desired the aqueous salt solution may be mixed with liquid monomer and the water evaporated.  The salts may be di-, tri-or hexavalent or complex chromium compounds may be employed. Chromates and bichromates are reduced during the polymerization. Salts of copper or manganese may increase the protective effect of the chromium.  In the examples (1).  A suspension of titanium dioxide in aqueous chromium fluoride solution is added to aqueous e -caprolactam. Polymerizate is effected at 250 DEG C.  The white polymerizate is spun to yarn which may be cold-stretched.  (2) Titanium dioxide, chromium acetate and manganese acetate are added to aqueous hexamethylenediammonium adipate and the mixture heated at 280 DEG C. in an atmosphere of nitrogen in a stainless steel vessel to evaporate water and effect polymerization.  The melt is spun to yarns which are cold stretched.  (3) Hot aqueous chromium fluoride solution is mixed with hexacediol and the water evaporated. Hexanediisocyanate is added and the mixture heated.  Excess isocyanate is removed in vacuo.  Threads, foils, tubes or bands of improved light stability can be made from the tough opaque melt. The Specification gives some comparative data of the physical properties of treated and untreated yarns.  Specification 649,481, [Group IV (c)], is referred to.

Abstract: 456,012. Bonnet fasteners. RIMES, C. L., 11, Richmond Street, Hull. June 12, 1935, No. 16886. [Class 44] A hook 19 is slidingly mounted on the inside of a motor-car bonnet and is connected by a spring 17 to the inner end of a lever 12 pivoted at 13. The device is shown in a midposition. To fasten the bonnet, the lever is pushed down until it lies flush with the bonnet. This extends the spring 17 and carrying it over the pivot 13 provides a toggle lock on the lever. To release the catch, the lever 12 is raised further and the spring 17 acts as a strut to move the sliding catch 19 downwards. Fig. 6 shows a modification in a closed position. A pin 32 carried by the hood passes through an elongated hole in the catch 26 which forms a pivot for the catch. In the closed position, the spring 29 raises the outer end of the catch so that a lug 24 holds the operating lever 12 in place. The fastening is released by manual depression of the outer end of the catch. When the lever 12 is thus released, the spring 29 throws it outward where it can be grasped for the completion of the release.

Abstract: 1,024,358. Vibrator supply arrangements. MULTISONIC CORPORATION. April' 24, 1964, No. 17115/64. Heading G4F. [Also in Division H3] Ultrasonic cleaning apparatus comprises a liquid-containing tank T (Fig. 3, not shown) to the bottom of which is attached a transducer comprising a metal bar 61 forming a loading element for a piezo-electric crystal 53 which is fixed to its lower face. The transducer is driven from a self-oscillating triode valve 23 via a tapping point on an autotransformer 42, which may have a ferrite core and is tuned by the capacities of the crystal (Fig. 2, not shown). The anode and grid of the valve 23 are connected via capacities 46, 37 respectively to either end of transformer 42, a tap 47 on which is earthed so as to form a Hartley oscillator circuit. The valve is supplied with A.C. by means of a transformer 11; in a modification means are provided to vary the output, comprising a separate anode transformer 62 (Fig. 4, not shown) with two seriesconnected primary windings, one of which is shunted by a variable auto-transformer 65. The arrangement is stated to be such as to avoid the production of standing waves as the transducer is driven both at its own resonant frequency and also at that of the crystal alone, due to harmonics generated in the autotransformer 42. It is also stated to be insensitive to changes in resonant frequency; the output of the auto-transformer tends to a square waveform and so increases the efficiency since the mass loaded transducer has two or more side resonances either side of the main resonances.
