Title: Hydraulic lifting unit on hand pallet truck
Inventor: SCHMIDLIN WALTER
IPC: B62B5/06
Filed: 1978-01-11
Abstract: This lifting unit, which is suitable in particular for pallet transport, has a spring-loaded reversing valve (19) which responds if a load-dependent pressure is exceeded and releases the inflow of the hydraulic medium to a larger cross-section (F) of the lifting piston (18) designed as a stepped piston. For the lowering operation, two different lowering speeds are available thanks to a control valve (33) which has two return-flow passages of different cross-sections. To this end, the control valve (33) has inside a valve sleeve (37) a valve cone (45) which can be moved successively via a plunger (38) into four different positions and thus clears different transfer cross-sections. <IMAGE>

Title: Toilet installation
Inventor: VIVIER HARRY
IPC: A47K13/30
Filed: 1977-03-10
Abstract: The object of this installation is to automatically provide for the cleanliness of the seat of the bowl. The installation uses the weight of the water, necessary for discharging the contents of the bowl in order to perform the tasks of cleaning and of exchanging the cleanliness screen (10, 30, 37) placed successively on the top of the bowl after each use, while the mechanical means used do not take up any extra floor surface with respect to the bowl. Brushes (65), which do not require rotation for performing their task, participate in the cleaning and drying of the cleanliness screens, as well as a cleaning solution prepared by the installation and which continues its action in the bowl after discharge of its contents. <IMAGE>

Patent CH-675918-A5 (CH)
Inventor: SAARILAHTI VEIKKO JOHANNES
IPC: G03B27/62
Filed: 1987-01-19
Abstract: A holder and layout device for originals intended for process cameras, especially for large colour pictures and maps, which consists of two surfaces (1, 2) fitted in frames (3, 4) that come against one another, one of which is a glass sheet (2) in order to show the picture towards the lens and the frames of which are hinged (5) on one side in order to be turnable in relation to one another, and a frame section round which the frames (3, 4) are able to turn essentially round their centre of gravity from a vertical to a horizontal position. It is the intention of the invention to achieve a simple, but nevertheless reliable and easy to use original holder, which in the horizontal position also acts as an effective layout table. In a holder in accordance with the invention the lower tiltable surface is the aforementioned glass sheet (2) that is shown towards the lens, in which case in the horizontal position it forms a light-table with the aid of the auxiliary lights (10). The second important feature of the invention is that the other surface (1) is a highly translucent matt membrane, for example polyester foil that has a chemically applied matt surface. The diffusion of the back-light by means of the matt membrane removes most of the scratches in the original picture from the copy.

ADVANTAGE - Increased heat storage and transfer capacity and braking performance.
Patent CH-617632-A5 (CH)
Title: Foam dispenser
Inventor: WRIGHT HERSHEL EARL
IPC: A47K5/14
Filed: 1976-03-31
Abstract: The foam dispenser comprises a flexible container (12) containing an emulsible liquid (18) and a certain volume of air, a porous element (14) separating the inside of the container from the dispensing orifice (30), and a pipe (16-20) connecting the inside of the container with the inside of the porous element. Thus, when pressure is applied to the container, the liquid penetrates into the porous element through the pipe and the air penetrates into it directly without passing through the pipe. The two fluids mix in the porous element and form the foam. Because of this arrangement, this dispenser can be used in any position. An orifice (28) controlled by a valve (32) allows the rapid intake of air after expulsion of the foam. This dispenser is suitable for food, cosmetic and maintenance products. <IMAGE>

Title: Stacking trolley for transporting and/or storing a stack of stackable chairs, and a stackable chair
Inventor: SCHAFFNER PETER
IPC: A47C3/04
Filed: 1982-07-05
Abstract: The stacking trolley has an at least approximately vertical support frame (40) composed of at least two supports (50). On the lower part of the support frame there is a rack (42) inclined relative to the supports (50) and intended for the stack (44) of the chairs (46) which are to be stacked.

Suitable for use with the stacking trolley is a stackable chair (46), the front legs (8) of which have a smaller outer distance between them than the inner distance between the rear legs (10). In addition, the width of the seat shell (2) is smaller than the inner width between the rear legs, and, as a result, the chair can be slid onto a chair of identical design, starting from the front and sliding to the rear. <IMAGE>

Title: Element wall
Inventor: VOLLENWEIDER ULRICH DR
IPC: E02D17/04
Filed: 1983-11-28
Abstract: The element wall is composed of one-piece, upright supporting elements (2) and a number of runners (6) supported on supporting elements interacting in pairs. These runners are supported in recesses (8) at the front edge (7) of the supporting elements in such a way that they can only be displaced laterally but are secured against a movement to the front. This construction ensures satisfactory covering of the field or foundation lying behind it and permits the greening of such coverings. At the same time, normal forces can also be absorbed by the wall. <IMAGE>

Title: Circuit arrangement for the charge pulse counter of a subscriber station
Inventor: DUBEY PIERRE
IPC: H04M15/28
Filed: 1978-10-18
Abstract: AC charge pulses are transmitted from the telephone exchange (1) via a coil-loaded line (3) to a subscriber station (4), the AC frequency of the charge pulses lying in the transmission range of the coil-loaded line and being 4 kHz. A band-rejection filter (9) for 4 kHz is connected between the end (8) of the coil-loaded line (3) and the subscriber station (4). A bandpass filter (12) for 4 kHz and a frequency multiplier (13) are disposed in a shunt (11) of the band-rejection filter (9). This multiplier feeds the charge pulse counter (10) of the subscriber station (4) which is designed to count charge pulses of the multiplied frequency. As a result, charge pulse counters for 12 kHz or 16 kHz can also be used when the charge pulse frequency is 4 kHz. <IMAGE>
