Filed: 1935-02-02
Abstract: 451,584. Golf clubs. TURNER, J. H., Frilford Heath Golf Club, Abingdon, Berkshire. Feb. 2, 1935, No. 3402. [Class 132 (ii)] Metal golf-club shafts are constructed with the grip portion separate lengthwise from the shaft and secured thereto by a resilient insert. Thus a springy rod or tube 9, Fig. 1, is secured to two end plugs 10, 11 which fit in the hollow ends of the grip and shaft parts and are riveted or welded therein. A packing or wrapping 12 around the part 9 gives an unbroken contour to the shaft. A plurality of rods or wires 9, Fig. 2, may be used instead of one, and stiff cane may be employed instead of metal for the intercept. Where several are used, or a flat rectangular bar, the disposition is made to give resilience in the plane of the swing. An additional flexible connection may be fitted at another point of the shaft, for example between the foot of the shaft and the club head. Specifications 11893/02 and 22968/03, [both in Class 132], are referred to.

Filed: 1974-01-24
Abstract: 1453682 Watering equipment M LAUREAU 24 Jan 1974 [24 Jan 1973] 03405/74 Headings A1B and A1D [Also in Division F2] A watering system comprises a wheeled vehicle guided by a series of fixed pipes 1 laid on the ground and having supply hydrants 6. The hydrants 6 are inoperatively closed by spring-loaded valves 10. The vehicle comprises water intakes 18 supported on beams 19 and guided by the vehicle and connected via carriages 23 to flexible feed means comprising tubular links 59 housing flexible conduits, and thence to a watering device 17. As the vehicle moves the intakes 18 are automatically attached by spring-toggle and hook connections having a crank release 128. When one intake 18 is attached to a hydrant 6 the motion of the vehicle moves the other intake 18 forwards and means are provided for the latter intake 18 to avoid the attached one and progress to the next hydrant 6. When this has occured pipe 105 provides a water pressure from the attached intake 18 to the newly engaged one causing stem 94 to open the valve 10 initiating the flow of water. The vehicle having progressed sufficiently, the toggle and hook connections are inclined so that water pressure in chamber 110 moves diaphragm 111 which can then release the crank 128 allowing the intake 18 to lift. To start the operation connection is made with the first hydrant 6 and the valve 10 is opened manually by pressing push-rod 146. The vehicle may be adapted to be driven by the water under pressure.

Title: Improvements in and relating to the treatment of cellulosic material with a view to the production therefrom of glucose
IPC: C13K1/02
Filed: 1941-03-14
Abstract: In treating cellulose with an acid such as sulphuric acid to produce glucose, an intermediate product described as cellodextrin is first formed and separated and is then hydrolysed to form glucose.  The cellulose is stirred or kneaded at room temperature with concentrated sulphuric acid containing an ester of an organic acid and an organic acid both of low boiling point, e.g., a liquid containing 77 per cent. sulphuric acid, 6 per cent. acetic acid, 11 per cent. ethylacetate and 6 per cent. water. Cellodextrin is precipitated by addition of an organic ester such as ethyl acetate and is washed with ethyl acetate.  It is dissolved in water, when occluded ethyl acetate separates as an upper layer and is removed, and the solution is heated with dilute sulphuric acid, sufficient of which may already be contained in the solution.  Ethyl acetate may be recovered from the residual liquors by distillation in presence of further quantities of acetic acid.  Excess of acetic acid is then removed by distillation under reduced pressure and the composition is adjusted for re-use. Amyl acetate may be used in place of ethyl acetate.  Preliminary purification of cellulose-containing material may be effected in the case of wood to secure pure cellulose therefrom, and in the case of straw by treatment with dilute acid to hydrolyse hemicellulose, and then with hot alkali, or chlorine and alkali, to remove lignin. Specifications 311,695, [Class 127], 353,028, 376,322, 376,323 and 376,372 are referred to.

Filed: 1965-01-27
Abstract: 1,035,795. Alarm clocks. KIENZLE UHRENFABRIKEN G.m.b.H. Jan.27, 1965 [Feb. 27,1964, Aug. 1, 1964],No.3593/65. Heading G3T. The alarm mechanism has means for reducing the frequency of the clapper 1. The clapper is fast with the alarm anchor spindle 2 on which a lever 4 is losely mounted but is initially oscillated with the spindle, though a detent 23 which engages a notch 27 in a second lever 24 pivoted on the lever 4. The other end of lever 4 engages a groove 6 of a mass 7 so that, on the outward swing of the clapper toward the bell, this mass is accelerated, and on the inward swing, after the mass has been brought to rest for a moment at the reversal, the mass is accelerated afresh. The mass is carried on the alarm spring wheel shaft 8. When this has rotated three-quarters of a revolution a cam 28 trips the lever 24 to release detent 23 and the remainder of the rundown period takes place at a rapid frequency of the clapper. In another embodiment, the mass 7<SP>1</SP>, Fig 3 (not shown) rotates in one direction only. Three grooves each having an outwardly concave part 12 and outwardly convex part 10<SP>1</SP>, are joined at radial ends 11 to form a continuous groove engaged by a pin 5 on the lever 4. Thus three periods of acceleration per revolution alternate with corresponding retardations. In another embodiment, Fig 4 (not shown) the mass performs a rectilinear reciprocating movement, whilst in a further embodiment, Fig 5 (not shown) it performs a continuous rectilinear movement in one direction.
