Abstract: 894,667. Meat pickling syringes. PETERSEN, F. H. Sept. 15, 1960 [Sept. 18, 1959], No. 31872/60. Class 49. [Also in Group XXVIII] In a syringe for injecting pickling liquid into meat, consisting of a piston cylinder registering at its end with a stout, hollow needle having lateral discharge holes, the inlet end of the needle is attached to the piston, and the needle carries a stop for limiting penetration into the meat. Pickling liquid is supplied to the cylinder 1 by way of a nipple 2 and a non-return valve 4, a spring 6 causing the piston 5 to take up the position shown; on inserting the syringe into the meat, penetration of the needle 9 is stopped by a collar 11, and continued pressing of the syringe then causes compression of the spring and passage of pickling liquid by way of a non-return valve 7 through the needle perforations 12 into the meat; on pulling the syringe out of the meat, the spring 6 recovers, a fresh charge of pickling liquid enters through the nipple 2, and, when the needle is fully out of the cylinder, the needle draws clear of the meat.

Abstract: 343,538. Wireless signalling. H A M M O N D, J. H., Hesperus Avenue, Gloucester, Massachusetts, U.S.A. Oct. 23, 1929, No. 32244. [Class 40 (v).] In a superheterodyne receiver for frequency-modulated signals, the amplitude of the output from the intermediatefrequency amplifier 24, 26, 30 is kept constant by current limiters 28, 29. The second detector 32 is preceded by a frequencydiscriminator circuit to change the frequency signals into amplitude signals. The coupling condensers 25, 27 of the intermediate-frequency amplifier are of high capacity to allow uniform amplification of the entire band of beat frequencies. The invention may be used in the reception of copying-telegraph signals (Fig. 5, not shown). Transmitter. To produce frequency-modulated signals, a condenser microphone is connected across the tuned circuit of a valve oscillator (Fig. I not shown), or amplified photo-electric currents vary the capacity of a condenser in the tuned circuit (Fig. 3, not shown), or selectively switch different condensers in the tuned circuit (Fig. 6, not shown). According to Fig. 4 amplified photoelectric currents produce varying voltages across a resistance 124 which is tapped to supply a pulsating voltage to the grid and plate circuits of a highfrequency oscillator 125.
