Title: Grinding machine
Inventor: ROBILLARD EDWARD GEORGE
IPC: B24B49/00
Filed: 1969-05-14
Abstract: 1,272,994. Grinding machines. HEALD MACHINE CO. 14 May, 1969, No. 24656/69. Heading B3D. A grinding machine comprises a base 11 on which are mounted a workhead 12 and a wheelhead 33, a main stepping motor 37 and a screw 36 for producing relative movement between the workhead and the wheelhead, control means 46 for introducing electrical pulses to the stepping motor 37 to produce a grinding cycle, and a secondary stepping motor also connected to the control means 46 to receive the same electrical pulses as the motor 37. An indicator 51 for indicating machine element positions is driven by the secondary stepping motor, and switches are provided which are operated by a potentiometer for operation at predetermined pulse counts for controlling operation of the machine. In the machine described, the workhead 12 mounts a workpiece 16 and includes a pneumatic gauge 18 operating switches 19, 21, 22 which respectively indicate the dressing size, the size at the end of a finish grind, and the final size of the workpiece. The wheelhead includes a wheel 35, and is mounted on a table 25 for transverse reciprocation under the action of the stepping motor 37. An adjustable size control 38 and a dress stop finger 29 engage with stops 31, 28 carried by a compensation slide 26 on the base 11 to perform automatic dressing of the wheel during a grinding cycle. The secondary stepping motor has a rotating shaft which drives the indicator 51 to indicate the position of the table 25. The shaft also drives one component of the potentiometer so that the voltage from the potentiometer is also related to the position of the table 25. Coarse compensation, 54, cycle start, 56, worm-wheel, 58, and new wheel, 52, switches, each including an adjustable potentiometer for delivering a predetermined set voltage, a voltage comparator in which the set voltage is compared with that from the first potentiometer, a numerical indicator indicating the set voltage, and a relay, are connected in such a way that when the potentiometer voltage equals the set voltage, i.e. when the numerical indicator 51 tallies with the preset value, the appropriate switch is operated and a corresponding cycle initiated.

Title: Method and device for shelling long tailed crayfish in particular shrimps
IPC: A22C29/02
Filed: 1957-08-12
Abstract: 826,711. Shrimps &c. shelling. HENNING, W. Aug. 12, 1957, No. 25412/57. Class 28 (2). A shrimp is passed between rollers 1, 2 and against thin moving knives 4 which cut off the shell at the sides. Further side cutting away of the shell especially at the side of the tail is done by a blade 4, Fig. 3, against which the shrimp is pressed by thin discs 9 on a resilient core, in co-operation with another roller 5. The other side shell is similarly cut off by similar but reversed rollers 5a and 6a. The shrimp is then dried by alternating cold and hot (200‹ C.) air to dry and shrink it from the shell. In this preparation the head and tail roots of the shell are separated from the flesh. The remaining shell parts can be rinsed away by a water or air jet as in Fig. 11. In Fig. 11 the shrimps slide down a shoot 19 in which the edge milling rollers 18 and 19a co-operate with resilient pressing rollers 17 and 17a respectively to slit each side of the shrimp in turn. Air or water nozzles in the shoot detach the shell parts. In Fig. 7 the shrimps 3 pass between rollers 10 and 11, the roller 11 being of elastic foam material and the roller 10 being composed of spaced discs with saw tooth peripheries which saw the shell into strips. The shrimps then fall between rollers 10a and 11a the same as 10 and 11 but interchanged so that the other side of the shrimp shell is sawn into strips which after drying can be blown off by a water or air jet. Other rollers with thorn-like pins on their peripheries may detach the shell parts. The heat drying makes the shell part brittle so that they can be grated or sieved off from the flesh. Arms with barbs interposed beteeen other rollers may also be used to tear off the shell.

The sheet may be rolled with longitudinal ribs (Fig. 4, not shown) or with lateral ribs, tapering of the sheet also being possible. A strip 45 Fig. 6 moving in the direction of arrow 59 may similarly be rolled in small increments by a roller 43 a roll 41 serving as a support. As with the sheet the strip may be rolled on both sides simultaneously. In place of the roller 43 an endless belt of cylindrical rollers supported by a backing plate may be used or alternatively a holder for rollers or balls which is reciprocated across the strip.
