Title: Unite tondeuse de gazon a reglage de la hauteur de coupe
Inventor: MILLS JOHN
IPC: A01D34/54
Filed: 1990-07-31
Abstract: Unité tondeuse de gazon dont la hauteur de coupe est déterminée par un rouleau au sol (18). Un élément de réaction (26) relié au rouleau (18) possède un arbre (28) à filetage de vis imperdable et porte une roue à main (32). Un bloc (38) fileté sur l'arbre (28) est relié au châssis (10) de l'unité tondeuse afin que la rotation de la roue à main (32) règle la hauteur de coupe. Le poids du châssis (10) est agencé pour agir sur la roue à main (32) de sorte qu'il sollicite des surfaces profilées de la roue à main (32) et de l'élément de réaction (26) l'une contre l'autre afin d'empêcher une rotation intempestive de la roue à main (32) pendant l'opération de coupe normale.

IPC: F24D3/16
Filed: 1991-10-30
Abstract: Air duct radiators are chiefly used for the decentralized supply of fresh air and the temperature control of workshops and sales outlets, as well as similar enclosed spaces or zones thereof, for example as in Figure 2. The installation is usually performed in a space saving manner below the ceiling of the enclosed space, for example as in Figure 1. In this case, the outer casing (13) of the air duct, which is equipped with through-flow tubes (4), functions as a surface (1) radiating to the enclosed space, and the inner casing (13) of the duct functions as a heat exchange surface (57) for the fresh air flowing through. The through-flow tubes (4) are normally rinsed with heating water or steam, or with cooling water. The air duct radiators, which are preferably assembled in an extrusion process in one piece or from a plurality of pieces made from light metal, are preferably connected to one another by means of flexible through-flow hoses (7) and connecting axles (20) which are secure against rotation. The interspaces (58) are covered by sleeves (8) or end sleeves (9) and simultaneously function as air pressure equalization chambers. In the case of design (A) the air exit (14) takes place between the outer casing (13) of the air ducts and the inner casing (13) of the sleeves. In the case of design (B) this happens through holes (15) in the sleeve casing (8,9) or in the duct casing (13). In the case of design (C), the casings (13) of the air ducts are fitted with continuous longitudinal slots (16) which, depending on requirement, can be covered entirely or partially by a cover profile (17). In another embodiment as in Figure 11, a heat exchanger (56) with through-flow tubes (4) is inserted into a normal ventilation tube (34) without through-flow tubes (4). <IMAGE>

Abstract: A photoelectrical switching circuit (l000) suitable for circuit integration and circuit-size reduction for producing a pulse-modulated light according to light emission pulse signals (gl) and detecting presence of an object by checking if the light is interrupted or reflected by the object, comprises a frequency divider circuit (200) and a signal output circuit (500) and may comprise further a control circuit (600). The frequency divider circuit (200) includes a counter formed by flip-flop and an operation stop circuit, wherein the counter generates light emission pulse signals with variable period and read pulse signals to pick up light sensing signals (p) and outputting the state of the final stage flip-flop as an operation signal, and the operation stop circuit stops the operation of the final stage flip-flop after the operation signal is input. The signal output circuit (500) which provides output signals after the operation signal is input, includes a shift register for shifting the light sensing signals (p) in step with clock pulses (a), a set output AND circuit (549), and a reset output AND circuit (553). The output AND circuit provides a logical product of a set output of the final stage and a set output of the m-th stage of the shift register to direct set terminals of the m + l-th and subsequent stages of the shift register, the reset output AND circuit (553) performs the same operation with the reset outputs and the reset terminals of the shift register, and then the signal output circuit (500) outputs output signals of the final stage of the shift register. The control circuit for making the period of pulse signals of the frequency divider circuit (200) fixed for a predetermined length of time.

IPC: D03D49/12
Filed: 1991-05-24
Abstract: The device (9A,7A,10a,10b,11A) for tensioning the warp yarns (T) allows for tension by operation of the tensioning members (11A,11B) to apply tension to opposite lateral ends of warp yarn sheet and can be adjusted as necessary and required in accordance with the time of weft picking and/or the time of shed closing. Thus, timed application of tension to warp yarns at the time of picking provides for smooth separation of warp yarns at the lateral ends, thereby forming a shed opening without a delay. As a result, failure in weft picking due to inadequate and improper shed opening can be prevented successfully. The decrease of diffrence of tension in the open shed and the closed shed points in the weaving cycle reduces vibration of droppers and as a consequence also fluffering and even the number of breaks of warp threads (T).

Title: Systeme de communication a infrarouge a synchronisation automatique
Inventor: TEICH RUDOR M
IPC: H04B10/10
Filed: 1990-10-26
Abstract: Le code consiste à transmettre une série d'impulsions, les séparations entre les impulsions successives représentant les mêmes données. Même si les séparations entre les impulsions successives représentent toutes les mêmes données, les séparations sont toutes différentes; cette caractéristique permet la synchronisation automatique. Les temps d'arrivée des impulsions successives sont enregistrés; les temps d'arrivée représentent la réception non seulement d'impulsions transmises, mais également du bruit détecté. Les différences de temps entre tous les temps d'arrivée (pas uniquement les temps d'arrivée successifs) sont contrôlées afin de vérifier la cohérence, à l'aide de plages d'intervalles de temps admissibles prédéterminées, lesquelles peuvent séparer les impulsions transmises successivement en une séquence de données. Lorsque l'on a effectué un nombre suffisant de ces contrôles, représentant un degrée suffisant de redondance, il est possible de dériver la valeur de données représentée par toutes les séparations d'impulsions.
