Patent FI-971325-A (FI)
Inventor: HALME MATTI KULLERVO
IPC: A61H/
Filed: 1997-03-27
Abstract: The invention relates to a sauna stove or a sauna stone compartment and a water-containing system belonging thereto. The form of the stone compartment metal mantle is that of a pentagonal prism, at least at the top. The sauna stove is placed in the corner of the sauna room, so that the front of it is at an angle, e.g. 45 degree, to the walls of the sauna room. Closely coordinated with the sauna stove there are one or two separate, vertical water containers which most suitably have a triangular, prismatic form. These have at least one acute angle and are provided with a hinge device, which makes it possible for the water container to be rotated into contact with, or away from, the stone compartment cover. The bearing part of the hinge may be fixed either to the stone compartment cover or to the sauna room wall. The combined projection of the sauna stove and water container system into the sauna room at floor level closely resembles a triangle. By adjusting the gap between the sauna stove and the water containers it is possible to affect either the temperature of the sauna bath water or the heating of the sauna room when the air circulates as a convection flow through this gap. The sauna stove and water containers may be so designed that the mantle over the stone compartment is for the most part covered, which means that the sauna stove's outward thermal radiation is prevented. The cover of the stone compartment thus needs no special thermal insulation. <IMAGE>

Compasses, magnetic.-In mariners' compasses of the liquid type, provision is made whereby the pivot pin for the card may be withdrawn through the bottom of the bowl, the card then resting on a hollow support. As shown in Fig. 1, the bottom a is of glass and has fitted therein a ring b into which a socket c, securing a cup-like member e, is screwed. Within the bowl, a cross-bar i supports a hollow pivot or support g. The pivot pin j is screwed within the support g, and access to it can be obtained by unscrewing a plug k, which is normally tight on a leather washer f. The ring b is slightly dished, so that when the bowl is inverted and the pivot pin removed, any air bell which may be formed will be located at the ring b, and can be removed by pouring liquid into the cup c.

Abstract: 1,170,451. Door operating mechanism. HAREFIELD RUBBER CO. Ltd. 27 Oct., 1966 [12 Jan., 1966], No. 1472/66. Heading E2M. A door operating mechanism comprises a fluid-operated, double-acting piston 4 connected to door 1 and a cylinder 6 which is slidably mounted on brackets 7, 10 so as to move when the movement of the door is obstructed thereby actuating means for reversing the direction of movement of the door or for stoppirig the supply of fluid to the piston and cylinder assembly. In operation, the door may be opened by operation of a push button, lever, cord, vehicle traffic pad, or photoelectric cell assembly, which causes air to be admitted into the cylinder to displace the piston to the left. When the piston strikes abutment 16, fluid pressure builds up in the right hand end of the cylinder so as to make the latter slide to the right and actuate a trip switch on bracket 10, thus causing fluid to be admitted into the left hand end and exhausted from the right-hand end of the cylinder so as to return the door to its closed position. If an obstruction arrests movement of the door to the latter position, then fluid pressure builds up in the left hand end of the cylinder to force the latter to slide to the left and actuate another trip switch on bracket 10 so as to cause air to be admitted to the right hand end of the cylinder and reverse the direction of movement of the piston. The piston may be pneumatically or hydraulically operated, and the door operating mechanism may be used in conjunction with conventionally hinged and folding doors, besides sliding doors. In the case of folding doors, the door operating mechanism may operate lazy tongs secured to the door so that vertical movement between the arms at one end of the tongs is converted into horizontal movement of the door.

Abstract: 232,688. Gramophone Co., Ltd., and Buckle, H. L. T. Jan. 24, 1924. Diaphragms not associated with tone-arms. - Relates to gramophones or the like, particularly of the kind having a large diaphragm, and consists in special means for enabling the diaphragm to stand upright when in use, to be laid flat when out of action, and to be readily locked in the operative position or to be unlocked by raising the diaphragm-supporting member. The diaphragm is mounted as usual in a ring 19, carried by a spider 18 which is pivoted to the apex of a triangular frame 14 by means of a screw and a friction mounting. The frame 14 is pivoted between lugs 13 on a tubular member 5, rotatably mounted on a tube 6, which protrudes from the axial bore of a hollow airm 3. This arm is mounted between bearings 4 so that it can swing in a plane parallel to that of the record. A spring-pressed latch 10 is pivoted on the arm 3, and when the diaphragm is in the vertical position shown, for playing, the latch engages in a notch 12 in the nose portion 5, looking it against rotation. When the machine is not required for use, the diaphragm-carrying framel is moved backwardly on its pivot between the lugs 13, until a projection 27 lifts the latch 10 out of locking engagement with the nose 5. The latter is then free to rotate and allow the diaphragm and its support 14 to be turned down to the horizontal position. The pressure of the needle on the record can be adjusted by means of a spring 23 within the tube 6, the spring acting through a plunger 22 upon a lug 21 depending from the frame 14.
