Title: Hay balers
IPC: A01F15/10
Filed: 1960-11-18
Abstract: 943,892. Hay balers. SPERRY RAND CORPORATION. Nov. 18, 1960 [June 16, 1960], No. 39734/60. Heading B5F. A hay baler comprises a case in which hay is baled by a plunger 30, a feed mechanism including a carriage 60 reciprocating in timed relation with the plunger 30, a piston 114 and a spring 111 mounted on a control member 110, to which the ends of a driving chain 104 are attached, so that fingers 80 mounted on the carriage 60 may be caused to operate resiliently when an overload of hay occurs on a receiving platform 42. Drive to the plunger 30 is from a tractor through a gearbox 34, a reciprocable chain 90 being connected to the plunger 30 by shear bolts, Fig. 8 (not shown). A spindle 100, to which both the chain 90 and the chain 104 are geared, transmits the drive from the plunger 30 to the feed mechanism. Hay is delivered to the platform 42 by a reel 38 having pick-up fingers 39. To enable the fingers 80 of the feed mechanism to return over hay on the platform 42 they are pivotable in an anticlockwise direction. In a modification, Fig. 11 (not shown), the chain 104 is endless, the piston being secured directly to the chain.

Title: Automatic telephone answering apparatus
IPC: H04M1/652
Filed: 1972-08-25
Abstract: 1405002 Telephone answering machines PIONEER ELECTRONIC CORP 25 Aug 1972 [4 Sept 1971] 39761/72 Heading H4K An answering machine circuit arrangement includes two timing circuits, one of which is arranged to produce a signal for a specific period from the time of receipt of the call and a second of which is arranged to produce a second signal a given time interval after the commencement of the specific period, the second signal being used to switch a signal sensing device responsive to the recepit of a preselected signal from a caller, from the line and to start the playback and recording mechanism of the machine. Receipt of the preselected signal during said time interval causes a special tape message to be transmitted to the caller. In operation a starting circuit 2 operates in response to ringing current to energize a first timing circuit 3 within 3-10 sees., this timing circuit producing an output which operates a relay Y1, for a period which governs the operating time of the machine. This relay causes the line 1 to be connected through to signal sensing device 6. A short given time interval later (2-3 sees.) timing circuit 4 produces an output which operates relay Y2 to disconnect the line 1 from the signal sensing device 6. Contacts of the relay Y2 also cause the motor for driving a reply message tape to be energized whereby a prerecorded message is transmitted to the caller in known manner. One of two messages prerecorded on different tracks of the same tape (shown as two separate tapes T1, T2) can be transmitted depending on whether the preselected signal is received by the sensing device 6 during the given time interval between the energisation of relays Y1 and Y2. If no such signal is received a general message contained on tape track T1 is transmitted via head H1. If the signal has been received relay Y4 is operated by the sensing device 6 and a special particular message contained on tape track T2 is transmitted via head H2. At the end of either message, stop foil causes the tape loop containing tracks T1, T2 to stop and a second tape containing track T3 is started for recording a message from the caller. In an alternative arrangement the tracks T1, T2 may be recorded on separate tape loops and a separate motor used for each tape loop. The preselected signal may be provided by means of a whistle or may be a spoken sound of high volume level.

A double-sided spinning-frame having an overhead creel and a pneumatic suction system for removing fibres when a yarn breaks, comprises nozzles connected to a main duct or ducts running along the length of the machine and communicating with a suction fan provided with a filter box located at approximately the mid-point of the length of the frame and to the side of the rove-creel. As shown, rove from bobbins 6 suspended from oppositely-extending members 5 supported by a central standard 7, is drafted at 9 and wound at 10. There is a nozzle 12 for each yarn; those on one side of the machine communicate with a duct 14 and those on the other with a duct 15. The ducts run the length of the machine; centrally of thin length they communicate by ducts 20, 21 and 23, 24 respectively with filter boxes 22, 25.

Further diluting gas is added by lines 21, 22 and 23 downstream of the valves which are so adjusted that the proportions of the total quantity of SO3 reaching the reactors are 40%, 30%, 20% and 10% respectively of the total theoretical amount of SO3 necessary to effect complete sulphonation. In Fig. 2 (not shown), diluting gas from lines 211, 221 and 231 is fed into line 10 upstream of the exits to valves 12, 13 and 14, so that the dilution of the gas mixture is cumulative.  Reference has been directed by the Comptroller to Specification 988,689.ALSO:A process for carrying out continuous exothermic reactions between liquid phase and gaseous phase reagents e.g. the sulphonation of dodecylbenzene or higher alcohols with SO3 diluted with SO2 and air, comprises passing a liquid reagent through a plurality of reactors in series, to which a diluted gaseous reagent is fed in parallel.

Abstract: 894,873. Twist tubes etc.; finishing yarns. ONDERZOEKINGSINSTITUUT RESEARCH. Nov. 30, 1960 [Dec. 1, 1959], No. 41200/60. Classes 120(2) and 120(3) In a false-twisting device comprising a travelling, endless, flexible, e.g. rubber, band which frictionally engages a running yarn at at least one position and thereby imparts rotation or twist thereto, the band also effects a rotational movement about its direction of travel in order to reduce frictional resistance to the slipping of the yarn around the band and thus reduce yarn tension. Thus the band may be wrapped around a wheel and over small rollers placed crossways in the periphery of the wheel and caused to rotate about their own axes by simultaneous rotation of the wheel about its axis: alternatively, the driving means comprises a pair of hyperboloid rollers the axes of which cross each other at an angle twice the magnitude of the angle at which the generatrices of the rollers and their axes cross. In the crimping process shown, yarn 3, in its travel between twist-stops formed by rollers 10, 11 and 13, 14, passes through an inclined heating tube 16, an air (cooling) zone wherein it is set in twisted form, and is guided by notches 19 in a plate 18 over a band 17 which is rotated and guided by hyperboloid rollers 22, 23, and free rollers 20, 21.
