Title: Packing installation for chocolates, chocolate-coated sweets and the like
Inventor: SCHMITZ HEINZ
IPC: B65B35/24
Filed: 1970-03-04
Abstract: 1,274,788. Packaging apparatus. F. THEEGARTEN. 4 March, 1970, No. 10454/70. Heading B8C. A plurality of parallel packaging machines A, B are fed with chocolates, sweets from a cooling belt 10 by strippers 9, 11, 12, 13 which can pivot out of operation about pivots 14 when there is an accumulation of sweets against the strippers to allow the relevant articles to travel on downstream. Each stripper covers a greater belt width than the preceding one and is arranged to feed either equal quantities (Fig. 1) or, decreasing quantities, Fig. 2, to the machines. As shown, four rows of sweets are laterally deflected by stripper 9 to an off-take conveyer 7 and passed via conveyers 5, 3, 2 to an intermittently rotating machine disc 1 which also receives sweets deflected by stripper 11 and passed via conveyers 8, 6, 4 and 2. Since it is arranged that the input to conveyer 7 is greater than its output, sweets accumulate upstream of stripper 9 which subsequently pivots to allow the sweets to pass downstream to stripper 11. Stripper 11, normally deflecting three rows of sweets, thus temporarily deflects seven rows of sweets into conveyer 8 which upon filling results in stripper 11 pivoting out to allow seven rows of sweets to travel to stripper 12 feeding machine B. The manner of operation is repeated for machine B although stripper 13 is not normally required to pivot since the output of sweets from the belt 10 is equal to or less than the total output of the machines. Upon the occurrence of an inadequate supply of sweets the above arrangement of strippers 9, 11, 12, 13 results in a sequential shut-down of the machines, i.e. machine B shuts-down first. Each stripper may be actuated to pivot-in again after a predetermined time or upon a predetermined emptying of the appropriate off-take conveyer 7, 8. The strippers which may be arranged on both sides of the belt (Fig. 1) are retained in the discharge position by adjustable springs (15, 16, Fig. 1), counterweights, or servo-motors. Conveyers 5-8 are designed as shaker tables and the four parallel conveyers 3, 4 have separate drives.

Title: Apparatus for winding weft thread on to bobins of shuttles of  looms with simultaneous weaving of weft
IPC: D03D47/26
Filed: 1971-04-22
Abstract: 1336371 Winding up bobbins for weft shuttles; travelling wave shedding looms VYZKUMNY USTAV BAVLNARSKY 22 April 1971 [28 April 1970] 10885/71 Headings DID D1E and D1J A thread winding apparatus for winding thread onto bobbins housed in weft shuttles and of the kind comprising a turret, Fig. 2, an endless chain 10 passing around the turret, under the warp 52 and then back to the turret, thread winding heads 4 distributed regularly around the circumference of the turret, means for causing a flyer arm 44, Fig. 4, on each winding head 4 to descend on a bobbin 12 and its shuttle 11 as it enters the turret, means for causing each flyer arm 44 to wind one weft length of thread onto the bobbin below it whilst the bobbin and its shuttle move around the turret and means for retracting the flyer arm 44 upwardly when a winding is completed, said apparatus being characterized in that there are (a) a clamp 18 on each winding head 4 for holding the free end of the thread 21 whilst the flyer arm 44 winds thread onto the bobbin and for releasing the thread end when the winding is complete; (b) at least one pair of scissors 24 for cutting the thread between the clamp 18 and its bobbin 12 as the shuttle and the bobbin therein are moved out of the turret and (c) a stationary bridge 26 of arcuate shape arranged around part of the turret, the bridge 26 carrying control means for starting each winding operation and operating the clamps 18 and scissors 24 in correct sequence. When a shuttle and its bobbin leave the turret and the thread between the bobbin and its clamp 18 is cut by the scissors 24, the thread end that then extends from the bobbin is gripped by pincers that are not shown and the shuttle then leaves the chain 10 temporarily in order that it may be passed through the shed of the warp 52. The chain 10 returns the empty bobbins 12 in their shuttles 11 to the winding heads 4 of the turret. When such a refilled winding head 4 passes a stop 19 on the bridge 26, the stop 19 acts on a projection 74, Fig. 3, on the winding head involved to cause a resilient laminae 45 to sweep through an arc causing a lever 39 to deflect clockwise in Fig. 3 and so cause a projection 73 to close a switch 30. Closure of the switch 30 energizes the winding head motor 20 to spin the flyer arm 44 and rotate the gear train shown in Fig. 3. Rotation of the gear train moves a flat surface on cam 36 away from the lever 39 and this causes the switch 30 to remain closed until the flat surface is again parallel with the lever 39 whereupon the switch 30 is opened and the winding operation ceases.

[Also in Divisions F2 and G3] A variable stroke hydraulic pump comprises a swash plate 11 actuating pistons 9 in a rotating cylinder block 7. The swash plate is biased to a maximum stroke position and its inclination is adjusted in response to the outlet pressure by fluid pressure supplied and exhausted through a passage 27, under the action of a pilot valve 20, acting on a piston (not shown). The pilot valve 20 is loaded by a spring 21, which also ensures rotation of the valve with the cylinder block, and the outlet pressure acts through conduit 24 on the right hand side of the valve. As shown the passage 27 is connected through passage 25 and valve 20 to an exhaust passage 29. When the outlet pressure reaches a predetermined valve, the valve moves to the left to connect conduit 24 to passage 27 through passage 26. The valve 20 is formed with a larger diameter portion 20a which forms an abutment for an annular piston 22. A solenoid operated valve 30 can be opened to admit outlet pressure to a chamber 19a which acts on the piston 22 to move the valve 20 to the left to reduce the pump displacement. The pump may be part of a vehicle transmission and the valve 30 is operated to set zero pump delivery when the engine driving the pump is started.

Abstract: 1505033 Indicating apparatus; accelerometers DAIMLER-BENZ AG 19 March 1976 [20 March 1975] 11093/76 Headings G1J and G1K [Also in Division B7] A warning indicator for use in a road vehicle comprises means for measuring the distance in front of the vehicle of an obstacle or a preceding vehicle, for measuring the vehicle speed, and for  determining the speed of approach to the obstacle, and a computor for calculating from said distance and relative speed values the braking deceleration necessary to avoid collision with the obstacle, this braking deceleration being displayed as a desired value indication 8 on a scale 1 of deceleration values. Preferably a second indication 9 shows the actual deceleration being achieved. The indications 8, 9 are light spots. On the scale 1, the line 6 represents zero deceleration and the scale marks 7 are at 1 m/sec<SP>2</SP> intervals. If the spot 8 lies in a zone 5 to the right of the line 6 there is no collision risk and the vehicle speed may be increased if desired. The zone 4 represents achievable decelerations on ice, snow, or snow slush; the zone 3 corresponds to achievable decelerations on wet or muddy roads, and the zone 2 to achievable values for a good dry surface. The zones have different colours, and provision may be made for switching out the colouring of zones 4 and 3, Figs. 2 and 3 (not shown) according to the road surface conditions. The distance to the obstacle may be measured by radar, and the speed of approach derived from this measurement. The actual deceleration is derived by differentiating the vehicle speed. If the computer detects an unrealistic measured deceleration, e.g. because of wheel locking, a synthetically generated value derived from the approach to obstacle speed is automatically substituted.

Abstract: 1,183,562. Pulse shaping circuits; digital transmission systems. COLLINS RADIO CO. 7 March, 1968 [22 May, 1967], No. 11204/68. Headings H4P and H3T. The bit-level of received binary data V IN  is determined by comparison with a reference level which is dependent both on the received data and on the regenerated data D. The received data is delayed by less than 1 bit at 11<SP>1</SP> and fed to unit 13<SP>1</SP> which generates the reference voltage to be fed to differencer 10<SP>1</SP>. In one embodiment of unit 13<SP>1</SP>, Fig. 3 (not shown), each received bit is assumed to have a theoretical value of 1v or 2v, and each is multiplied by 1À5 or 0À75 respectively, dependent on the output D, so that a theoretical average voltage of 1À5v is developed on a summing capacitor. This reference voltage varies with variations in the average bit level. In a second embodiment of unit 13<SP>1</SP>, Fig. 4 (not shown), the level of bits at 2v is halved, under control of output D, before the received data is passed to a differential amplifier. This feeds an integrating amplifier which generates the reference voltage, a portion of the reference being fed back to the differential amplifier. Referring again to Fig. 2, the output of unit 10<SP>1</SP> is gated at bit rate, the samples switching a bi-stable 16<SP>1</SP>. To prevent faulty operation should the bit level of all received signals fall below the current reference level unit 21 compares the present value of a bit with the value of the previous bit. If the present value exceeds the previous value by a certain percentage bi-stable 16<SP>1</SP> is forced to its 1-state. The reference level is set initially by transmission of a series of like bits prior to the data bits. This series is recognized by unit 24 which alters the time constant of unit 13<SP>1</SP> so that it quickly sets up a reference level dependent on the level of the series.
