Title: Improvements in tobacco cutting machines
IPC: A24B7/12
Filed: 1952-07-23
Abstract: 711,445. Cutting tobacco. KORBER, K., and KOPER, E., [trading as KORBER & CO. KOMMANDIT-GES., K.]. July 23, 1952 [May 12. 1952], No. 18622/52. Class 5 (1) The fixed knife 12, which co-operates with the rotary knives 9 of a tobacco cutting machine, is secured to the mouthpiece 11 by easily shearable pins or screws 13 so as to give way if any solid body in the tobacco comes between the knives, and when a screw breaks spring 21 closes electric contacts 22 of wires 23 to stop, or retard preliminarily, the machine. The screws 13 may be weakened by longitudinal bores. To prevent the sheared screws 13 falling into the cut tobacco a wire 15 passes through holes in their heads, the wire being secured to the knife 12 by screws 16. The knife itself is likewise retained by a chain 17.

Patent GB-440790-A (GB)
Title: Improved cereal food product and its method of manufacture
IPC: A21D13/08
Filed: 1935-07-05
Abstract: A biscuit of porous texture is composed of superposed criss-crossed united layers of numerous, thread-like and substantially parallel filaments.  The dough is passed between a pair of rollers, one of which is circumferentially scored with fine closely related grooves and the other roller is smooth.  The dough is removed from the rollers in the form of filaments, which for close settings of the rollers are more or less separate from each other.  When the rollers are sprung slightly apart under the pressure, the filaments may be more or less united by very thin webs.  Such sheets or filaments are deposited on a surface, e.g. a conveyer belt, and each layer is laid with its filaments at a right angle to the filaments in the layer below.  Out of a sheet of about eight such layers, the biscuits are stamped or cut.  The pressure of cutting presses the filaments of adjacent layers together, and somewhat more at the margins than elsewhere, the pressure being just sufficient to unite the layers without compacting them.

Abstract: 147,450. Atlas Metallindustrie Ges. June 11, 1918, [Convention date]. No Patent granted (Sealing fee not paid). Compulsory differential driving.-The differential shafts of endless-track vehicles are connected by gear trains including friction clutches, by the engagement of which relative rotation is imposed on one shaft with respect to the other to effect the steering of the vehicle. The differential shafts 11, 12 are connected by chain-gearing 22 - - 29 with solid and hollow shafts 13, 14, 30, 31 fitted with friction clutches 32, 33. On throwing-in the clutch 32 the differential shafts are connected through the gear train 22, 26, 27, 23. Similarly, the engagement of the clutch 33 effects the connexion through the gear train 24, 28, 29, 25. By these means the shaft 11 may be made to turn faster or slower than the shaft 12 and the vehicle thereby steered. The tracks are driven from the shafts 11, 12 by chain gearing. In a modification one of the differential shafts is geared with co-axial solid and hollow shafts, the other differential shaft being geared to a shaft which can be clutched to either the hollow or solid shafts.

Abstract: 1425066 Grinding VOUMARD MACHINES CO SA 25 April 1973 [25 April 1972] 19649/73 Heading B3D [Also in Division G3] The power or current in a grinding wheel rotating motor is measured and used to control the frequency of a supply to a traverse motor so as to vary the speed of displacement of the wheel relative to a workpiece. The base frequency of the supply is set by selecting the charging rate of a capacitor in a relaxation oscillator. As shown, a transformer 3 produces a voltage signal indicative of the power supplied to wheelrotating motor 2. The signal is fed through a reference voltage circuit 5 including a series transistor voltage regulator, Fig. 2 (not shown), a gain control circuit 7 and a threshold circuit 8 to one input g of a relaxation oscillator 9. Pulses are produced by the oscillator 9 at a frequency dependent on the voltage at input g and the current at a reference input h, the two input signals being fed to a four-layer breakdown element (38), Fig. 3 (not shown), connected to a monostable circuit. The pulse output is fed through frequency dividers 12, 13 and a logic gate selector circuit 14 to a control circuit 15 for a stepping motor 16 which displaces the grinding wheel relative to a workpiece. A control assembly 1, which may include programming stages, provides signals for controlling a rotation direction selector circuit 17 and for setting the gain control 7, frequency selector 14 and reference current supply 10 circuits which may include switching transistors, in accordance with the operating phases of the grinding machine. A circuit 18 may be provided for counting pulses supplied to the motor 16 and thus supplying position information to the control assembly 1.
