Meat 21 especially frozen is tenderized by applying H.F. electrical or mechanical vibrations. In Fig. 2 a coil 13 with applied H.F. vibrates a hollow shaft carrying a clamp 10 for the meat. In Fig. 3 a similar vibrator 20 vibrates the water 19 in which the frozen food 21 is immersed. In Fig. 4 a number of vibrator discs 26 rest on the food 21. In Fig. 7 a rotating drum 61 carrying applicators as in Fig. 9 operate on food on an endless belt conveyer 58, the food coming from a cold store or freezer 56. Each applicator, Fig. 9, comprises a piezoelectric crystal 44 between electrode plates 42, 45 to which is applied H.F. thin conductors 72, 73, the contact 72 being closed only when the plate 45 recedes when pressing on food. Fig. 6 (not shown), is a similar device for vibrating small food pieces, e.g. a chop or steak.

Wire 7 is fed through a roller straightener 8 by grippers 10 actuated by a cam 11 on a slide 9. The cam is rotated by a lever 12 and rod 15 from adjustable coaxial cranks rotated at different speeds and selectively coupled to the rod 15. On the feed stroke the lever 12 is swung to grip the wire and then to move the slide. Screws 19, 20 adjust the pressure of the grippers. The wire is fed through a helical die 33 with mandrel 34 and exterior rolls 28 backed up by rolls 30 which reduce friction in the die which may be lubricated. A blade 37 then moves forward and co-operates with the mandrel to sever the wire.

Title: Improvements in or relating to a method for the secret transmission of messages with the aid of a code
IPC: G09C1/00
Filed: 1934-10-11
Abstract: 450,233. Codes. OLFFEN, J. P. VAN, 138, Sarphatipark, Amsterdam. Oct. 11, 1934, No. 29182. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 12, 1935]. Drawings to Specification. [Class 146 (ii)] Code messages are transmitted in sets of nine letters each made up of three threeletter groups each representing three possible meanings, a tenth letter or the absence of a tenth letter being used in decoding to indicate which of the meanings is intended. The letters of the alphabet are arranged in threes, AAA, AAB ... ZZZ, and each group is given three meanings indicated by an index consisting of one of the numbers 1-9 and a letter a, b, c. When three groups are to be transmitted, their index numbers are added together and the index letters are arranged in the correct sequence. The numbers 1-27 (all the numbers to which the index numbers can total) and the 27 combinations of the letters a, b, c are arranged as the co-ordinates on a sheet, and the letters of the alphabet are filled in consecutively along vertical and horizontal lines leaving a blank in each line. By taking the letter or blank at the intersection of the lines corresponding to the sum of the index numbers and the combination of the letters, an indication is obtained of the meaning to be given to the different groups. In decoding, the three code groups are separated, their index numbers added together, and the combination of index letters ascertained from the key sheet by means of the sum of the numbers and the tenth letter or blank in the code. When splitting up a message into sets of three three-letter groups, one or two. three-letter groups may remain, and in order to complete the set, the group AAA may be employed and given the index number O. Also, if the sum of the index numbers and the combinations of index letters of any of the sets give a blank for the tenth place, the last three-letter group of the set may be replaced by the group AAA. For additional secrecy, the tenth letter may be included in different positions in successive code sets In order to transmit a five-letter code, the combinations of two letters of the alphabet are given the meaning of some of the three-letter groups, and the three-letter group corresponding to the first two letters of the five-letter code-word and the last three letters are transmitted. The three-letter code groups are numbered and the numbers can also be used for coding purposes.

R C C C , the gain of each amplifier being equal to the loss in its associated phase-shift network. The output from each stage is connected to a tapping point on a potential divider 2 from which a variable phase output may be derived from the slider 3. In order to adjust the gain of each stage to be equal to the loss in its associated phase shift network the output from each stage is fed via a rectifier 4, Fig. 2, to a common point, thus obtaining a D.C. signal proportional to the amplitude of oscillation. This signal is compared with a reference signal V REF , to provide a further signal which after amplification is used to vary the resistance of a symmetrical transistor TA connected in a potential divider network across the output of amplifiers stage GA. Similar control transistors are provided in the other amplifier stages.

Title: Plug and plug insertion means for nuclear reactor pressure vessels
IPC: G21C13/02
Filed: 1962-08-07
Abstract: 1,001,580. Reactors. GROUPEMENT ATOMIQUE ALSACIENNE ATLANTIQUE. Aug. 7, 1962 [Aug. 7, 1961], No. 30192/62. Heading G6C. [Also in Divisions E2 and F2] A plug and plug inserting and removing apparatus for use in holes of nuclear reactor pressure vessels comprises a hollow plug within which is situated a means for locking the plug in the hole, and apparatus for gripping the plug, positioning it in the hole, unlocking it and removing it. Fig. 1 shows the plug 1 which contains locking means in the form of a folded aluminium spring 11 having its two ends folded back on themselves to form a pair of bolts 12 which extend through the plug wall to engage an annular recess 6 in the hole 2 to be plugged. To insert the plug, a closing sleeve 22 is placed on the grapple body 14 and the plug retained thereon by a resilient band 23 in the closing sleeve engaging an annular recess 9 towards the top of the plug. The gripper 14, which is carried in tongs 18 of a charging machine is pressed into the hole 2 until the bolts 6 engage, and then retracted. To remove the plug, the closing sleeve 22 is replaced by a similar sleeve (22<SP>1</SP>, Fig. 2, not shown) in which, however, the resilient retaining ring 23 is placed considerably further from the lower end of the sleeve. Because of this, as the gripper is held downward on to the plug to be removed, annular extension 20 passes between the outermost strip of the spring 11 and the plug body to retract the bolts before the resilient ring in the gripper engages the plug recess 9. When such engagement occurs, the bolts have already been withdrawn, and the plug is consequently removed by reversing the charging machine tongs.

Title: Purification of lactams
Inventor: BEER LUDWIG
IPC: C07D201/16
Filed: 1963-07-31
Abstract: Lactams, produced by rearrangement of oximes derived by irradiating saturated cycloaliphatic hydrocarbons and nitrosyl chloride or a mixture of nitric oxide and chlorine are purified by contact with 0.01-10% of Mg, Al, Cu, Zn, a metal of the iron group, a chloride or carbonate of a Group IIA or IIB element, AlCl3 or an oxide of an element of Group IIIA or IIB or the iron group or of copper and distillation. Rearrangement of the oxime may be effected at 80-150 DEG  C. by H3PO4, 80-100% H2SO4, oleum containing up to 10% SO3 or a solid catalyst. The lactams may have 5-12 carbon atoms, e.g. laurolactam, capryllactam, piperidone, oenanthlactam and omega-amino-decanoic acid lactam. They may be liquid or gaseous or dissolved in an inert solvent, e.g. an aliphatic, cyclo-aliphatic or aromatic alcohol.  Catalysts specified are Zn amalgam, a Raney metal of the iron group, e.g. Ni, ZnCl2, CaCl2, ZnCO3, MgCO3, oxides of Fe, Zn, Al, Co and Ni and mixtures thereof.  The metal may be granular and may be activated, e.g. by treating Zn or Al with I2 or a mercury salt.  The purification may take place at 0-250 DEG  C. in an inert atmosphere, e.g. H2, and the pressure may be atmospheric or above or below.  A polymerization stabilizer, e.g. 2,4,6-tri-tert.-butyl-phenol may be present. The product may be distilled out batchwise or continuously and the mixture may be filtered prior to distillation.  In Example (1) laurolactam is treated under an atmosphere of nitrogen with, Zn dust activated with mercuric chloride, nickelous oxide, ferrous oxide, cupric oxide, magnesium activated with iodine, zinc dust, zinc dust aluminium powder and copper powder activated with mercury, iron powder, CaCO3 and BaCl2.  In Example (2) Raney nickel and Raney cobalt are used separately in admixture with Zn dust. In Example (5) methanol is used as a solvent.  In Example (6) the lactam is capric lactam.ALSO:In Example 1 laurolactam prepared and purified by a particular process (see Division C2) is fused with 3% of hexamethylene diammonium adipate and heated at 270-280 DEG  C. under a nitrogen atmosphere of superatmospheric pressure to polymerize it.
