Abstract: 1497564 Game N C MILLER and S J MURSET 18 Feb 1975 [21 Feb 1974] 6780/75 Heading A6H [Also in Divisions B6 and G5] A question-and-answer game card device comprises a supporting sheet 1 having disposed thereon first indicia 5a-5e identifying questions; a removable first opaque layer 6 overlying respective question indicia; second indicia 7a-7e identifying a plurality of possible answers to each question, one of which answers is correct; third indicia, such as 10 and 11, indicating whether the selected answer is correct or incorrect; a second removable opaque layer 8 overlying respective third indicia; and indicia 12 printed on at least one of the opaque layers to frustrate attempts to cover-up or conceal an attempted incorrect answer. In use, a question such as 5a is selected and is revealed by rubbing off the opaque layer 6; an answer, e.g. 7d, is then selected and is revealed as correct by indicia 11 when opaque layer 8 is rubbed off. A selection such as 7e would be revealed as incorrect by the indicia 10. The sheet 1 may also carry indicia 14 identifying a category for the questions, and indicia 3 indicating at least one of several possible prizes for a correct answer. The sheet 1 may be of card or paper with a top coat of polymer or hard wax. The opaque layers may be of ink, wax, a paper or plastics seal or the like. The question and answer indicia can be in ink or can be of the micro-encapsulated ink spheres type for pressure activation. A second embodiment is described with reference to Fig. 2 (not shown).

Abstract: 783,635. Washing-machines. MASCHINENFABRIK P. PFENNINGSBERG GES. March 8, 1955 [April 20, 1954], No. 6799/55. Class 138 (2). [Also in Group XXXVII] A water-actuated switch in a washing machine, comprises a lever 6 pivoted at 11 having a funnel-shaped end 5 and connected to a bridging contact 14, so that when the maximum water level in a container 1 is reached water flows through an overflow pipe 4 and impinges on the end 5 thereby tilting the lever 6 and bridging contacts 15. The end 5 of the lever is disposed in a funnel 9 attached to a waste pipe 8. The overflow pipe is S-shaped and is fitted to the container near the bottom. When the switch 15 is closed current flows from R<SP>1</SP> to O energizing a coil 21 which actuates contacts 20, thereby supplying current to (a) heaters 19, (b) the washing process winding of the motor 18, (c) the coil 21 through the contact 22 so that this coil is energized even when the switch 15 is opened. At the end of the washing process an automatic switch (not shown) energizes the coil 25 which actuates contact 26 which breaks the circuit to the coil 21 and supplies current to the centrifuging process winding of the motor.

Abstract: 1449671 Door check units I H W ENG Ltd 7 Feb 1974 [13 Feb 1973 17 May 1973] 7055/ 73 and 23472/73 Heading E2X  Apparatus for checking the opening of a door hinged to a frame comprises a housing 77 for securing either to a door, or to a frame, an elongate arm 10 slidable relative to said housing and adapted for securing to the other of either the door, or frame, a detent on one longitudinal surface of the arm, and a coiled spring 24 on the housing and provided at each end with engagement means which are urged by the spring to engage the arm, one of said engagement means engaging said longitudinal surface having the detent, and the other engagement means engaging the opposite surface of the arm which is not provided with a detent. As shown, the arm 10 has an aperture 11 for pivotal connection to a door and includes along one edge detent recesses 12, 13, a curved portion 15 and a projection 16 along the other edge, and a nose stop 14. The arm 10 passes between rollers 27, 28 rotatably mounted respectively on the ends 25, 26 of the coil spring 24, the spring ends 26, 25 passing respectively through aligned holes 22, and aligned slots 23, in the side walls 18 of the U-shaped housing 17, and the walls 18 having inwardly turned lugs 19 and flanges 20 for fastening to the door frame. In operation, as the door is opened, the arm 10 is drawn from the housing 17 between the rollers 27, 28, the roller 27 engaging the curve 15 so that a greater pressure is exerted on the rollers 27, 28 as the arms 25, 26 are forced apart. As the door is opened further the roller 28 engages in the recess 12 and checks the door. Increased door-opening force overcomes the spring pressure and allows further opening of the door until the roller 28 engages in the recess 13 and against the nose 14, the roller 27 bearing against the projection 16. In a modification, Figs. 5-7, not shown, each roller (67 or 68) has an integral side flange (69 or' 70), to centralize it in the housing (57), and bevelled side edges. In a further modification when the lower roll (88) finally engages a detent (73) in the lower edge of the arm (50a), Figs. 8, 11 not shown, as the door is opened fully, the upper roller (77) rides over a nose portion (76) on the upper edge of the arm (50a).

Windscreens. - In a supporting-device for a vehicle windscreen of the kind comprising at each side of the vehicle upper and lower substantially parallel arms 11, 12 pivoted to the back of the front seat or similar support and a rear screen-supporting arm 10 pivoted to the arms 11, 12 so as to form a self-locking linkage, one or both of the structures is provided with a supplementary locking-bar 21 pivotally and slidably mounted relative to the arms 10 and adapted at its free end 21b to abut against a stop 11<a> carried by the structure so as to maintain the supporting-device in its extended condition. In the construction shown the end 21b of the arm is notched to engage a stud 11<a> on the arm 11, the central part of the arm is slotted at 21a to give a combined sliding and pivotal movement at the point of connection 20 of the arms 10, 11, while the other end of the arm is pivoted at 22 to an extension 9<a> of the windscreen pillar 9. An unlocking of the screen is thus effected by swinging the screen and arms 9 forwardly in relation to the arms 10. Each arm 10 may also be provided with a supplementary catch 23 having a notch 23<a> co-operating with the pivot 22 to prevent inadvertent unlocking of the screen, and the arms 21 may have spring plates 24 adapted to engage the studs 11<a> when the screen is fully collapsed.
