Title: Golf practice device
IPC: A63B69/36
Filed: 1973-03-17
Abstract: 1428780 Golf practice device W T DURKIN 20 Dec 1973 [17 March 1973] 12948/73 Heading A6D A golf practice device, which is used by a golfer to practice iron shots so that the club head 17 is moving in a downwards direction (along path 4B) at the moment of impact with the ball 3, includes a flat base 1 having a portion 2 whereon the practice ball 3 may be placed and struck by a golf club 17, a trigger device 5 mounted on the base and so positioned as to lie in the path 4A of the club 17 during the initial portion of a back-swing movement, and means associated with the trigger device and adapted to cause a control element to appear at a point spaced to the rear of the ball 3 when the trigger is actuated. As described the base 1 consists of an upper layer 1A, e.g. of hard rubber, and a lower cushioning layer 1B, e.g. of foamed plastics material, the base 1 being formed with an inclined track 9 and a hole or socket 8. A bent wire member consisting of trigger arm 5, straight portion 14 and keep member 13 is pivoted to the base 1 by hinges 15, 16, the keep member 13 being arranged to hold a control ball 10 at a station 11. In use the golfer places the practice ball 3 at 2 and control ball 10 at 11 and then commences his stroke. During the initial part of the back swing 4A the club engages trigger 5 to pivot the wire member (the trigger being held in its pivoted position by magnet 5A) thus raising the keep member 13 as shown in Fig. 2 to release the control ball 10 which runs down track 9 into hole 8. When the golfer makes his down stroke 4B he must attempt to strike the practice ball 3 without dislodging the control ball 10. In this way the golfer is trained to hit downwardly on the practice ball as is normally desirable in iron play. In a modification (not shown) the control ball 10 is moved to its position behind the practice ball 3 by a solenoid actuated by an electrical trigger device. In a further modification the control element could take the form of a marker which is uncovered and so made visible upon operation of the trigger device. Alternatively the control element could take the form of a member which is caused to project upwardly from the base upon actuation of the trigger.

Filed: 1937-05-10
Abstract: 496,757. Impedance networks. LANDMANN, A. May 10, 1937, No. 13237. [Class 40 (iii)] The . coupling between two circuits of a band-pass filter is varied to control the band-width, while an undesired shift of the band of frequencies is prevented by modifying the impedance across a coil inductively coupled to one of the coils of the two circuits. The coils 1, 2, form part of the two tuned circuits and are inductively coupled ; the coupling is varied by short-circuiting a coil 4, and compensating coils 6, 7, are simultaneously open-circuited to alter the impedance of coils 1, 2 and prevent a shift of the band of frequencies. The coupling may be wholly or in part capacitative, condensers being switched in simultaneously with the opening or closing of the compensating coils, Figs. 3, 4 (not shown).

Patent GB-438119-A (GB)
Title: Improvements in the production of artificial textile materials
IPC: D06M11/38
Filed: 1934-05-02
Abstract: Cellulose ester yarns are saponified non-uniformly along their length and are then subjected to stretching in the presence of a medium which has a greater softening action on some parts of the yarn than on others.  Portions of the yarn may be completely saponified and other portions unsaponified prior to the stretching process.  The softening medium may have a greater effect on the less saponified than on the more saponified portions or vice versa.  The softening medium may have a further saponifying action.  The products generally have a varying affinity for dyestuffs as well as a varying denier along their length.  By further saponification of the products, regenerated cellulose yarns of varying denier may be obtained.  The change in the degree of saponification along the length of the yarn may be gradual or abrupt so that on dyeing sharp or gradual colour changes or cross-dyed effects may be obtained.  The saponifying agent may be caustic soda or potash, sodium silicate, methylamine or other aliphatic amine.  Saponification may be superficial or uniform through the cross-section of the filaments.  The softening medium may be steam, hot water, or an organic solvent.  The yarns are treated preferably while travelling.  In examples, cellulose acetate yarns while travelling, or in hanks are treated at intervals along their length with caustic soda and sodium acetate, or portions of the yarns are coated with wax and then the whole is immersed in caustic soda solution.  The yarns are then passed through aqueous dioxane, acetone, glycol mono methyl ether, or ethyl lactate, or ethyl acetate and toluene, and stretched while in the softened state.  The yarns may be weaved, knitted, or netted together or with other textiles to form fabrics or other materials showing colour effects when dyed. Specifications 332,263, [Class 15 (ii)], 370,430, 371,461, 412,600, 417,220, 428,224, 429,103, 430,349, 430,350, 430,351, 430,489, 432,027, and 432,028 are referred to.

Abstract: 741,887. Reservoir pens. AUSCHER, D. Y. May 13, 1953 [May 27, 1952], No. 13446/53. Class 146(3) A device for feeding ink to the Writing member of a pen comprises in combination with thai member two ducts one withir the other, the inner duct being freely movable within the outer to control the flow of ink, each duct opening at one end into an ink container, while its other end lies adjacent the tip of the writing member. As shown, a drawing pen comprises a shank 1 forming a container 2 having two ducts 13 and 14. The duct 13 is frictionally slidable within a sleeve 12, such that its outer end 15 may be adjusted relatively to two blades 5 and 6. The duct 14 is slidable within the duct 13 and carries a sleeve 17 which limits the forward movement of the duct 14 by engagement with the rear end of the duct 13. A weight 19 is free within the container, such that during operation the weight 19 engages the rear end of the duct 14 to project the duct 14 towards the tips 16 of the blades 5 and 6. Ink flows from the container 2 through the duct 14 during writing, while air flows to the container through the duct 13. The distance apart of the blades 5 and 6 is adjustable by a screw 10 co-operating with a member 7 encircling the blades, such that the width of a line to be drawn can be varied. In a modification, the ducts supply a split nib, the inner duct being curved towards the nib, such that its end is adjacent the nib hole. In a further modification, the inner duct is of U-section, the outer duct being of yielding material and contacting the nib.
