Title: A method of and apparatus for peeling pineapples
Inventor: LOVELAND MALCOLM WALLACE
IPC: A23N7/00
Filed: 1969-06-10
Abstract: 1277741 Apparatus for peeling pineapples ATLAS PACIFIC ENG CO 10 June 1969 29465/69 Heading A4C A method of peeling pineapples comprises rotating the fruit through at least one substantially complete turn while performing a first cutting operation to remove substantially all the rough peel portions and subsequently rotating the fruit through at least one substantially complete turn while performing a second cutting operation to remove substantially all the uncut peel material remaining after the first cutting operations. The cutting operations may be performed, using helical or annular cuts, at one location or at two spaced zones or the first operation may be performed in two stages at spaced locations 39, 41, Fig.2, at a first zone 38 and the second operation may be performed in two stages at spaced locations 43, 45 at a second zone 40. Before peeling a fruit is centred with respect to a hollow, finned spindle 49, which makes a first core cut, by  fingers 57, the fruit being then passed stepwise to locations 39, 41 where cutters 65 and (67), (69), Fig.3 (not shown) and (71, 72) respectively make first and second sets of spaced annular cuts. The fruit is then moved stepwise to locations 43, 45 where similar spaced cuts are effected to perform the second cutting operation. The spindle 49 is rotated through substantially one revolution at each location and each cutter makes a cut in a place substantially parallel to the plane of the tangent to the fruit surface adjacent that cutter. The cut peel is collected separately from zones 38 and 40. The peeled fruit is removed from spindle 49 by a pusher (75), Figs.1, 8 (not shown) and forced on to a coring tube (77) which makes a second core cut, an annular section then being cut from the periphery by a stationary or rotated cutting tube (83), Fig.9 (not shown), this annular section being cut into segments by radial blades (85). Each cutter may comprise a cutter head 91, Fig.4, having a cutter 119 rotated on a shaft 109 in a stationary housing 93, a cut-depth gauge 123, adjustable relative to cutter 119 but movable therewith parallel to the shaft axis towards, or away from, a fruit by an actuating cylinder 97, or a spring 101, respectively. Cutter 119 has a flat face 120 for riding over the fruit, peripheral cutting teeth (121), Figs. 5, 6 (not shown), and sharpened projections 126 on the opposite face to face 120 which separate the cut peel into segments. The cutter heads may move from one work zone to the next with the spindles 49.

Title: Data handling system
Inventor: AVAKIAN EMIK ALEXANDER
IPC: H04L12/18
Filed: 1963-07-25
Abstract: 1,039,311. Electric selective signalling systems. BUNKER-RAMO CORPORATION. July 25, 1963, No. 29522/63. Heading G4H. An information retrieval system, for example for stock quotations, comprises a plurality of remote interrogating stations 10, Fig. 1, and a central station which comprises a first multiplexing means 16 to successively scan the interrogating stations for digital interrogating signals, a data retrieval unit 48, 46, and a second multiplexing means 76 to distribute the retrieved data to the interrogating stations. As described each interrogating signal comprise four dialled digits. These are assembled on a drum 14 by a " query logic " unit 24. The drum is arranged so that around its circumference there are 1024 segments each corresponding to one of the interrogating units and in which a dialled interrogating signal is assembled. Further tracks 33 on the drum provide appropriate clock and address pulses. When a complete four-digit interrogating signal has been assembled on the drum it is transferred, together with the address of the interrogating station 10 from which it came, via a temporary store 44, to a data retrieval unit 48-providing this unit is not " busy ". This unit then extracts the data called for by the interrogating signal from a drum store 64 and assembles it in a sixty-six six-bit word register 66. Each of the six-bit words corresponds to an actual speech word which it selects from a store of sixty-four speech words 78 for transmission back to the interrogating station via the second multiplex means 76. This occurs as follows. The sixty-six six-bit reply is written on the drum 14, by sixty-six heads 70 at a position around the drum corresponding to the interrogating station. The speech drum 78 has one speech word recorded on each track so that the complete vocabulary of speech words is presented repeatedly and simultaneously to the multiplexing means 76. An electronic switch 72 takes the data from a single read head 70 and is arranged to progress to the next head 70 after the speech drum 78 has made a complete revolution. The speed of drum 14 is such that each six-bit word for each interrogating station is read by head 70 about 25 times for each revolution of the speech drum 78. Thus in operation a single head repeatedly passes the six-bit words from its track to the multiplexing means 76 which selects and transmits the appropriate speech words to the interrogating stations. The system also includes the feature that to avoid any interrogating station having to wait for its reply until the switch 72 returns to the first head 70, the replay is shifted cyclically in register 66 before being transferred to the drum 14 so that the first word of the reply goes in the track which is next to be selected by the switch 72.

A device for connecting a windscreen wiper blade to a wiper arm so as to be rockable about an axis extending substantially longitudinally of the blade comprises a ear or ears projecting from the back of the blade into one or more recesses of a co-operating second member carried by the wiper arm, the end walls of the recess or recesses being provided with aligned apertures by means of which the second member is pivotally connected to the said ears. A hollow die-casting 7, Fig. 1, attached to a wiper arm 16 is fitted over upstanding ears 4 on a channel member 2 either riveted as at 5 to the blade backing 3 or sprung thereon. A pin 13 passes through aligned apertures in the ears and end walls of the casting and allows the members 2 and 7 to rock relatively to one another. The pin has a smaller end 11 fitting in a smaller aperture in one end wall of the casting and riveting of the end 13a prevents the pin from moving longitudinally. The ears 4 may be struck from the back of the blade backing 3. In a modification, Fig. 3, the ears 18 are struck from the back of the blade backing 21, but may be formed on a separate member as described in the first embodiment. The ears are resilient and formed with dimples 17 which are engaged in apertures 20 in the end walls of the die casting 19. The curved portions 23 on the end walls of the casting facilitates the springing of the dimples into the recess of the casting during assembly. Rocking movement of the blade is limited by the ears engaging the lower portions of the interior of the side walls of the casting. Various modifications regarding the hinge arrangements e.g. a pin with a collar and a spring between the ears and surrounding the pin are described, and Specifications 523,177 and 685,291 are referred to. Springs may be incorporated for holding the die casting normally upright with respect to the member provided with the ears. Specification 665,359 is referred to in second Provisional Specification.
