Title: A rotating impact sprinkler
Inventor: DRECHSEL ARNO
IPC: B05B3/16
Filed: 1991-07-15
Granted: 1995-04-27
Abstract: A rotating impact sprinkler comprises means for connecting a pressurized water column to a rotating joint which supports a rotating assembly (7) which is formed by a tubular body (8) with a nozzle (12) for generating a jet, an oscillating arm (20) and deflection means mounted at the end of the arm so as to interact with the jet. The deflection means comprise at least one main deflector (40) which oscillates elastically in a direction which is transverse to the arm between a central equilibrium position, in which the surface affected by the jet is minimal, and at least one lateral abutment position, in which the surface affected by the jet is maximal. The variation in cross section in passing from the minimal surface to the maximal one is sudden, so as to instantly increase the withdrawal of energy from the jet and generate impulsive forces on the deflector. <IMAGE>

Title: Entry-phone for housing block - has door relays independent of number of door speech units to simplify growth
IPC: H04M11/02
Filed: 1969-04-24
Abstract: The entry-phone system has each door speech unit assigned to a relay that operates whenever one of the unit's call buttons in pressed and establishes the wanted connection to the internal speech unit and in so doing interrupts voice connections to other door units. Each relay has a hold circuit to maintain the voice connection. A control signal is derived from a line's call current and controls a monoflop. The latter operates a second relay that briefly interrupts the current to the first relay's hold circuit and releases the relay.

Title: Expanding wall plug assembly - has conical expander which is driven inwards over core to wedge plug in hole
IPC: F16B13/06
Filed: 1969-06-14
Abstract: A wall plug has an outer thin-walled sleeve (4) containing an inner core (1) with an outer conical surface, around which an expander (2) with a mating conical inner surface locates. In the free condition, the expander (2) protrudes a little from the sleeve (4). The sleeve is a loose fit in a hole (5) in a wall, having a flange (13) to locate it against the face of the wall.

Title: Fixture for stamping identification numbers on work pieces - can be operated during actual machining work
IPC: B44B5/00
Filed: 1969-08-02
Abstract: The end of the workpiece is gripped by the surface of the tapered hole of the end plate which is rigidly attached to the spindle.

Title: Adaptive equaliser for digital transmission systems - has differentially-delayed input sampler passed to adders
IPC: H04L25/03
Filed: 1971-06-03
Abstract: The adaptive equaliser, for digital transmission systems, has a first adder to subtract estimates of the trailing interference from sample of the incoming signal before passing to a quantiser and shift register. A second adder subtracts from the delayed input samples estimates of both the trailing and the leading interference and passes the result to a quantiser and a shift register. A third ader subtracts from the further delayed input samples estimates of both trailing and leading interference; and similarly for a fourth adder. The outputs of the third and fourth adders are passed over separate quantisers to the common shift register.

Title: Component for building playground climbing frames - has struts with stepped ends for making overlapping connections using connecting bolts
IPC: A63B9/00
Filed: 1972-07-28
Abstract: The building component is used for making of climbing frames or other playground equipment. The frame component is shaped as a short length of a ladder with parallel struts connected by transverse rungs. The ends of the struts are stepped so that struts can be connected by overlapping the stepped ends, which have transverse holes for connecting bolts. A variety of physical education and training equipment can be built from these sections for playground and nursery school use. A flat cutout is made at the mid-length of a strut with similar bolting holes. These stepped ends and stepped mid-sections facilitate construction of different kinds of structures. These components can be made from timber or from metal or from plastics and in the latter case snap fit fastenings can be used.

Abstract: PURPOSE:To impart the headed information to the service requirement, which is made at each time, with the use of a single device by reading out the whole data in an random accessible digital memory within the time period necessary for the heading operation. CONSTITUTION:A four-bit decimal counter 10 is advanced stepwise in response to the designated information at a terminal 21. If one of FFs 19 is set at a time, the content at that instant is transferred to be stored in one group of FF groups 11 with gates. Decoder groups 12 have outputs for respective groups to generate signals in one of the outputs in accordance with the content of the FF groups 11 so that one of the clock pulses of a pulse generating circuit 18 is selected through an AND circut 13. The output of this circuit 13 is fed through an OR circuit 14 to one input of AND circuit groups 16. The other input is supplied with the information of the  respective bits of the PCM signals read out of a memory 15 so that the headed information is generated in the output. Thus, it is possible to impart the headed  information to the service requirement at any time.

Patent JP-S6336979-B2 (JP)
IPC: B60Q1/05
Filed: 1983-03-22
Abstract: PURPOSE:To keep off any positional slip in a light body in time of a control miss and so on, by installing a timer circuit in a driving circuit which houses the light body or makes it shift to an upright position. CONSTITUTION:A first timer 9c consisting of a condenser C, and a resistor R2 is installed in a control device. In a state of being lighted, when contacts 5a and 6a of light switches 5 and 6 are selected to each of off-terminals 5b and 6b by a control miss and then again put back to the original position each, a light body stil keeps its upright state whereby there is no hindrance for car driving, though a continuous rating current for the light body comes to a stop all the while these contacts are changed over. That is to say, when the contact 6a is situated in an on-terminal 6d, a control transistor 9b of a control circuit 9 conducts a base current via a resistor R6 and with this, a driving transistor 9b is conducted, while charging the condenser C1 of the timer 9c is carried out. Therefore, under this condition, even if the contact 6a is selected to the off-terminal 6b by a control miss, a driving transistor 9a keeps its conducting state for the duration of the charging time of the condenser C1, and sets an exciting coil 4b in excitation.

Abstract: The pliable portion of the article (80) has a first end portion (1) and a second end portion located at opposite ends of the encircling portion of the article. The first end portion (1) includes an elasticized fastening system (120) having at least one segment (15) which is capable of being elastically shirred along at least a portion of its length. The shirrable portion of the segment (15) comprises an elastomeric member which, prior to the securement of the first and second end portions of the article to one another, is maintained in a prestretched and tensioned condition in the desired direction of shirring. The opposed ends of the shirrable segment in the article (80) are interconnected to one another through the prestretched and tensioned elastomeric member. The prestretched and tensioned elastomeric member is maintained in tension by securing it in fixed relation to at least one rigidifying member (28) to form a composite structure which is strong enough to resist collapse in a direction parallel to the tensile forces acting upon the prestretched and tensioned elastomeric member. In a particularly preferred embodiment, the rigidifying member (28) has a fixed portion (30) permanently secured to the first end portion (1) of the article (80) and a releasable portion (32) which can be separated from the first end portion of the article. The releasable portion (32) of the rigidifying member (28) preferably includes means for securing it to the second end portion (2) of the article (80), and the act of affixing the releasable portion (32) of the rigidifying member (28) to the second end portion (2) of the article (80) automatically releases the tension in the prestretched elastomeric member. Elasticized fastening systems of the present invention can be produced at high speed from continuous webs and cut into discrete segments which are transferred onto a continuously moving web at predetermined points along its length, all while the elastomeric member is maintained in its prestretched and tensioned condition by the rigidifying member.
