A method of making a cheese vat from a synthetic plastics material and having a perforated wall through which whey can penetrate includes producing the perforations in said wall by means of a laser beam. The perforations may be cylindrical or holes of varying diameter.

An induction coil, preferably for an induction heater, comprises a working coil, an outer casing and an inner lead-through channel for the workpieces, such as rods or tubes, which are to be treated in the induction coil. The region of the outer casing closest to the working coil consists of a layer of a rubber-elastic compound outside which is arranged a concrete casing. Using a two-part outer cas...

In a plant comprising an evaporator (1), Fig. 1 (not shown), a motor 3 to which a consumer, e.g. a pump 9, is connected, a condenser (14), and a condensate pump (16), the motor 3 is provided with a slide valve 4 and a cylinder 5 having a piston 8. To the slide 6 is secured an extension rod 7 which is connected to a piston rod 12 of the piston 8. In order to permit the valve to operate without vibr...

The device is for trapping and drowning rats, and has a container with a partly covering lid. Under the lid is a food board which entices the rat to a tip plate under the open end of the container aperture. - The plate tips the animal to the bottom of the container, from which leads a passage to a tank partly filled with liq.

When transporting unlopped wood there is a need for compacting it as much as possible at the loading. According to the present invention, this is realized by using two pairs of supports 1-4 between which the wood is placed, and which 1-4 are provided with compacting arms 5- 8, which 5-8 are displaceable along associated supports 1- 4, and swingable outwards in their upper end position.

The device is for the removal of rivets from a brake caliper with a lining, and comprises caliper retaining components and a counterpiece. In the active position, the counterpiece locates against one side of the caliper, while a stamping mechanism grips the caliper from the other side. - The counterpiece and the stamping mechanism are movable to and from each other, and relative movement is also p...

The invention is a valve situated in the discharge line of a water heater or the like in worksheds and weekend cottages in order to automatically open for water drainage when temperatures are so low that there is a risk of freezing. A body that is temperature-dependent as regards volume (14; 23) lies against one end of the valve spindle (6), whose other end has a stop cock plug (5). Around the val...

The mechanism is for fitting a platform or auxiliary frame on a chassis frame structure in a lorry, and includes a two-part clamp (3,4). The lower clamp part (3) is fixed to the chassis frame, whilst the upper clamp part (4) is attached to the platform or auxiliary frame. Both clamp parts have attachment back pieces (6,11) and stirrups (8,12). The upper clamp part back plate (11) has a lower secti...

The invention is a collapsible car support, which can be used after the vehicle has been lifted up. It is made up of two beams (namely a longitudinal beam (1a) and a transverse beam) connected to a T-shaped body (that is horizontal in its working position). The underside of three free ends of the beams contain support points, forming plates or projections (1c), while the centre of the longitudinal...

The vernier calipers have a tension spring (1) functioning dependent upon a guide fillet (2) and positioned counter to the underside of a running arm (3). The spring is placed in a position (K) at the front part of the running arm (3) which lies as near as possible to the measurement plane, and a specific torque is obtained which acts anti-clockwise in relation to the force engagement point (J). T...
