Abstract: Les moules qui existent actuellement et qui sont utilisés pour la fabrication de blocs de béton sont en métal ou en bois. Ils sont aussi volumineux et lourds et nécessitent beaucoup d'espace pour le remisage et pour leur utilisation. Dans la présente invention, les moules sont en plastique et ils sont de dimensions variées selon la grosseur du bloc désiré. Ils sont légers et non fixes et peuvent aussi facilement être manipulés. Ils sont en plus, munis de poignées qui en facilitent encore la manutention. Cette invention est utile en ce qu'elle permet d'entasser et d'empiler les moules pour sauver de l'expace, en ce qu'elle permet une livraison plus rapide des blocs puisque le séchage n'a pas à être complètement terminé avant, en ce qu'elle permettrait éventuellement à un particulier de fabriquer ses blocs de béton sans s'équiper de toute une infrastructure encombrante et en ce qu'elle accélère le temps de séchage en réduisant les surfaces. Les moules étant jetables après usage et réalisables à un coût raisonnable, ils ne nécessitent pas d'espace pour être rangés après usage pour les cas où on ne prévoit pas en avoir besoin une seconde fois.

Abstract: ABSTRACT An arrangement for effectively distributing light from a first or main light conducting member into a second or branch light conducting member is disclosed. The second light conductor is movable relative to the first to selectively receive light therefrom.  The first light conductor is formed with a radial bore in which the second light conductor is movably recived. The end face of the second light conductor adjacent to the first light conductor is inclined and finished to mirror surface.  The first light conductor has a unique configuration for effective distribution of light and elimination of undesirable fringes in the output light.

Abstract: Method and Apparatus for Reducing Operating Noise in Axial Piston Pumps and Motors Abstract A method and an apparatus are disclosed for reducing operating  noise  in  axial  piston  pumps  and  motors.   An elongated passage  (88, 98) connects the outlet plenum (86) of the apparatus directly with each cylinder (30) during its discharge stroke, the passage being positioned between the point  (68)  at which the discharge stroke begins and the leading  edge  (78)  of  the  discharge  port  (74)  of  the apparatus and the length and cross-section of the passage being  sufficient  to  permit  gradual  attenuation  of  any pressure differential between each cylinder and the outlet plenum before  the  cylinder  opens  to  the  discharge  port leading to the outlet plenum.  See Figures 1 and 2.

Abstract: METHOD AND APPARATUS FOR MONITORING PERIPHERAL BLOOD FLOW            ABSTRACT OF THIS DISCLOSURE     A heat exchanger (31) cools at a programmed rate a prede-termined area of skin.  The rate at which the area of skin changes  in  response  to  temperature  change  of  the  heat exchanger and the rate the skin temperature returns to normal are then measured and compared to standard rates over a number of cycles.  Impaired peripheral blood flow is evident espe-cially on subsequent cycles as vascular disease slows the rate of  return  to  normal  temperature  of  the  skin.   The  heat exchanger has a cooling chamber  (110)  with one side of the chamber being a cooling surface (111) adjacent the skin.  An injector (130) is connected to a source of fluid (75) having a boiling point at ambient pressure less than the temperature to which the skin is to be cooled.  The injector injects fluid into the chamber and onto the side of the cooling surface opposite the skin to boil the fluid on the surface to cool the surface and the skin.

Abstract: ABSTRACT FOLDING PUSHCHAIR      A folding pushchair has  a  chassis  provided  on each  side  with  two  chassis  struts  (6,7)  carrying wheels  (8).   The  struts  are   pivotally   connected together, and  swing  out  of  a  folded  position,  in which they lie side by side, into a  position  of  use, in which they are  secured  by  means  of  a  fastening device (14).  This  device  has  to  swing  upwards  to release the struts but a seat,  and  hence  the  weight of a child in the pushchair bears down  on  the  device (14), thereby avoiding accidental folding in use.

Abstract: METAL PACKING AND METHOD OF MANUFACTURE               ABSTRACT OF THE DISCLOSURE       Metal vapor/liquid contact plates are disposed in face-to-face contact with respective corrugations inclined to the horizontal across a notional plane.  In one embodiment, a per-forated lamella or partition plate is disposed across the notional plane.  The metal packing which may also be of slit or louvered construction is disposed within a vapor/liquid contact column for the purpose of bringing about mass and heat transfer between liquid and vapor passing in opposite direct-ions therethrough.  The body portion of each metal plate comprises metal that has been slitted to provide both surfaces thereof with a very large number of apertures with little wasted material.  The metal lands defining the apertures are, moreover, twisted and angulated.  The apertures in the plates also trap liquid and expose it to the vapor stream on both sides of the expanded metal affording self-spreading of the liquid and turbulent vapor flow therethrough.  In this manner, the assembly affords optimal pressure drop characteristics, surface to vapor passage area ratio, and vapor/liquid distribution character-istics.  The lamella plate formation may also afford select flow and turbulence characteristics through capillary action between offset lamella land areas of the corrugated sheets.

Abstract: Abstract A heating installation comprises a heat pump, radiators having valves, and a control device (18). A desired value generator (45) for the upstream temperature delivers as an effective desired value (T'vs) a desired value (Tvs) guided by a guide parameter such as the external temperature (Ta) and/or reference room temperature (Ti). The control device (18) comprises a comparator (47) which compares the guided desired value (Tvs) with a variable limiting value (G) higher than the downstream temperature (Tr) by a predetermined temperature difference (.DELTA.T).  The desired value generator (45) reduces the effective desired value (T'vs) at least down to the variable limiting value (G) when the latter is exceeded by the guided desired value (Tvs).  In this way, the condenser temperature of the heat pump is kept low.            Fig. 2.

Abstract: A TESTING DEVICE FOR TESTING A DRAINAGE SYSTEM FOR LEAKS              ABSTRACT OF THE DISCLOSURE       A testing device is disclosed for testing a drainage system for leaks, the testing device being selectively connectible to a source of fluid flow. The testing device includes an elongate tubular member having a first and a second end. The tubular member is disposed in fluid tight series communication between the drainage system and the drain. The tubular member defines an internal annular ledge which is disposed between the first and the second end of the tubular member.          The tubular member also defines a first lateral hole which is disposed longitudinally away from the ledge. A removable blocking disc sealingly engages the ledge for temporarily preventing flow of fluid from the drainage system to the drain during the testing of the system for leaks. A closure is disposed within an access opening for permitting access to and removal therethrough of the blocking disc from the tub-ular member subsequent to the testing of the system after the removal of the closure from the access opening. The access opening and the first hole are disposed longitudinally on opposites sides of the blocking disc. The closure defines a second hole such that the second hole is selectively connectible to the source of fluid flow for filling the drainage system prior to testing thereof. The second hole is sub-sequently connected to the first hole for permitting drainage of the fluid between the drainage system and the drain subsequent to the testing of the drainage system for leaks and prior to the removal of the blocking disc.  A first and a second plug cooperate respectively with the first and second holes for plugging the same subsequent to the removal of the blocking disc from the tubular member.
